lighten flywheel

[boonman]

look at the ones they have posted in this thread, they count, yet they have helped no one...

 

Yup, I believe the ONLY reply in here that was informative was wrote by myself. Hrmmm, I didn't see you whipping out any flywheel specs.....

"you may have been walking a lot longer than me, but that doesnt mean you are any better at it."

 

Nope, but I HAVE lightened ALOT more flywheels than you, and may be, just a little bit better at it.......

So anyway, everyone just needs to pull their twisted panties out of thier asses

 

I don't wear panties, so that ain't gonna happen.... And

and have a good time

 

I defintely will. I have a wedding to go to. Free booze, and good food. I'm all for that...... A little dinner, cocktails and some dancin'. Ain't nothin better...

 

Well, except for takin a rip on the shee........

 

Lokar, bro. No hard feelings...... It's all good....

[lokar]

 

You know, I have feelings.... and they hurt!

 

 

PS- I meant nothing personal, just some harmless fun. I am sure all of you are great people. I guess its hard for me to convey my sarcasm over the internet, but I am just a free spirit who just loves a good arguement. So to everyone, dont take it personally and I hope to at least contribute something to this board. I have read plenty of good and usefull information on this site. Although my I love fourwheelers, my expertise is in automotive. My last project had me searching through countless boards and forums having to deal with punk ass teeny boppers who think they know all and are complete assholes to anyone new. I actually never really posted on those boards, but I would always see the same thing, 90% of the answers people got were 'try a search' or some other useless answer. (I say useless, because most of the time people were looking for a different answer or could not find it using the search) Anyway......

I rarely get involved in matters like this but you are way out of line here.

First of all if you knew anything about this site you would realize that the top 20 posters in this site are not 14 year old punks but rather passionate about this site and spend many of their waking hours contributing. Yeah some of it's BS but most of it isn't. These are the most dedicated people that this sport has and if you had been around here more than 15 minutes you would have read the post about "positive feedback" and recognize that these guys would do anything for a fellow banshee owner.

They do this even to the point of giving away information that they make money with.

If you were around more than 15 minutes you would realize that boonman also runs a machine shop and in reality is giving you information that he makes some of his bread and butter with. As generous as I am, I wouldn't do that.

Consider too that every 15 minutes some idiot finds the HQ and posts some retarded thing like "what's the best premix" or "what kind of pipes should I get" and "what kind of tires are best" or another top 10 idiot thing to ask is "does lightening the flywheel do anything" or better yet "how do you lighten a flywheel".

The response to that is #1 do a search. It should take all of 15 seconds to find 200 postings about it. And if that's too much to read, then think about how irritating it is to reply to this question every other day.

The #2 response is nothing. You, like everyone else that scraped together enough money to get a lathe or signed up for machine shop or knows someone who has seen a lathe one time, will just have to practice on your own and hope it works.

So far 2 of the top contributers to this site offered you more than you should have expected and they got a punk reply from someone who claims to be an adult but acts like a 12 year old who just learned how to cuss.

There are to ways you can deal with this.

1- appologize without a bunch of BS extras and learn from the people who know what they are talking about or...

2- check out Bluetraxx.com Since most of us are banned from there anyway, you will never have to deal with our immaturity again.

[Oilsmoke]

Lokar So how old are you?

 

What parts do you make for a Living?

[BdBanshee]

i was wondering just how much top end you would lose by lighten the flywheel.....i might be interested boonman to send mine to you......again sorry for adding more ?s to this post....yea yea yea i can go to search and look it up but i am just to god dam lazy this morning and this post just so happened to be right in front of my eyes. so bash me, make fun of me blah blah blah....i could carelsess..i am just out for answer

 

To get back on topic...............

 

You will not lose any topend, you will gain throttle response.

 

If you want more informative answers do a search, we have went over this many times in the past.

[Meat]

If I could justs through my 2 cents on the "search for it "controversy. I think this thread is the perfect reason why no one should ever reply to a thread with "search for it". It just causes chaos and animosity among the members. The new guy just asked some simple, altho common questions that should have gotten a quick and to the point reply. You must remember, we were all new to this at one time and learned via asking questions. If we condone the asking of questions, then whats the point of coming here.?

 

When you come to a message board to talk about quads\whatever, you come here to interact with others, thats the beauty and the fun of these internet forums. When you ask a question on a subject, its usually because you don't know the answer and you expect your question to be answered. If you wanted to search for your answer, then the poster would have searched, but he didn't, he asked a question on our wonderful forum and should be granted a respectful reply.

 

advantages? disadvantages? TRY A SEARCH!

If you guys insist on just telling people to try a search, then i suggest you phrase it so it doesn't come off as an insult. Try something like.... "lokar, this is pretty popular mod. Look around, you'll find plenty of info." And thus.... avoiding fighting and bickering and the hijacking of a thread.

 

Finally. Lokar. The main advantage of a lightened flywheel is a faster revving motor. The flywheel is mounted on the end of the spinning crankshaft. By shaving off some of the flywheels material, the crankshaft has less mass to spin, allowing the motor to rev faster than with a heavier flywheel. There are disadvantages too. Heavier flywheels will produce a smoother powerband, the powerband will be easier to ride because the revs are not going up and down and up and down as much. You would not want to shave your flywheel for woods\XC type of racing where your racing in a lower gear and at lower speeds where you don't want to be shifting and revving the engine. Same holds true, but to a lesser extent for mx racing...... you'd sacrifice a few hp for a more controlled\easier to race kinda power. You can buy flywheel weights or heavier aftermarket flywheels. Higher revs are more desirable for drag racing or building a super fast TT motor, or building a dune motor. You wont find many if any aftermarket heavier Banshee flywheels because there's not much of market for.... Banshee's racing in the woods and MX tracks, they are just not as common as the Banshee's built for speed and raw power. Heavier flywheels have another perk, heavier flywheels can help with low speed stalling, more spinning mass makes the engine harder to stall. If your threading your quad through the woods and your in first gear and you have to slow to a crawl to get over that rock garden and through those trees, a heavier flywheel has the advantage. You can buy flywheel weights and heavier than stock aftermarket flywheels for every size 2-stroke dirt bike, the Honda 250r and Iv seen em for the new YFZ450's. There IS market and a valid point for heavier flywheels. MSD makes a Banshee ignition that eliminates the flywheel alltogether ! They market thier ignition towards the MX Banshee's, where others perfer the slower revving stock flywheel when MX racing. It all comes down to personal preferrence on this flywheel issue. Some guys like em fast and wicked and high revving... others perfer a more mild, easier to race, tork'ier motor.

 

From what Iv read here on this forum..... EVERYONE and I mean every single person who had Boonmans flywheel mod done were 100% satisfied with the way thier motor ran with the lighted flywheel installed. If your a weekend warrior kinda rider than check into the lightened flywheel. The worst kind of riding for a lightened flywheel would be XC\Hairscramble racing through the woods.

I do disagree with one thing on Meat's reply. When I raced XC and hare scrambles, I switched to a lightened flywheel, and I liked it. I felt that the engine came out of the low end bog a bit easier. And with the -2 swingarm, it hooked up just fine, and wasn't a bear to hang onto. I'm not ported though.

[lokar]

Meat, I could not have said it any better myself.

 

Okay, now that the drama is behind us, I have a specific question about this. Boonman, with your experience in the woods, did you feel that you had to shift more and had a more 'radical' power band with the lightened flywheel? or was your feeling that everything was better. I had been thinking about adding some weight to the flywheel to keep it from dropping out of the revs. (This is from my experience with cars.) Do you have any experience with a weighted flywheel?

[Meat]

I do disagree with one thing on Meat's reply.

Ya know I never comment too much on these lightened flywheel threads cause I personally have never tried one. Im thinking that a heavier flywheel might not be a good match for the banshee's engine design and thus there are no disadvantages to lightening it.

 

I personally feel that the reason it works so well on the Banshee is that it is a twin cylinder motor. Since it fires every 180 degrees of crankshaft rotation, there is a lot less need for flywheel weight than on a 4 stroke that fires every 720 degrees.

 

I can see needing weight to get to the next power stroke when the crank has to go around twice!

 

If you don't want the power and RPM's coming on faster(acceleration), then you probably don't want your flywheel lightened.

[boonman]

  Boon would you say there are no disadvantages to a lightened flywheel

 

I would definitely say that in my own experience, there aren't any disadvantages. HOWEVER, I do not have a ported bike. I am on stock porting. (well, just a little clean up of the transfers I did myself, but no timing changes.)

 

Boonman, with your experience in the woods, did you feel that you had to shift more and had a more 'radical' power band with the lightened flywheel

In my woods riding, (which is about 90% of the riding I do) I didn't find that I had to shift much. My clutch is retardedly stiff, so I hate using it, only to start out. Or, if I absolutely have to. So, most of my riding is rolling on and off the throttle. I have noticed that the THROTTLE RESPONSE is greatly increased. I guess that one could say that it makes it a slight amount more "hairy" to ride. The powerband comes on instantly. When you want it, it's there. No four stroke like smoothness. My bike bogs less with a lightened flywheel. When you need the RPM's, they are there. No delay. You hit the throttle, and it happens. Now, keep in mind that I run a -2.5" shortened swingarm. So, traction isn't a problem. Well, except in sand, where I get too much traction. Anyways,

 

I had been thinking about adding some weight to the flywheel to keep it from dropping out of the revs.

This isn't needed, because like BD said, there is power being applied to the crank every 180 degrees of rotation. You don't need the mass to keep things spinning untill the next power stroke. Also, these effects only hurt you when you are trying to accelerate. Small amounts of weighted change on a crankshaft yield huge changes in what happens inside the motor. HUGE. The less rotating mass you have, the easier the engine can perform combustion and make power when YOU WANT it to happen. Not after you want it to happen. I would say that if you have stock tires, and a stock swingarm, this is not the mod for you in the woods. There is more of a "hit," not much, but it is noticeable. It may light the tires a little easier on a stock bike. but, I haven't noticed any problem on mine. But, remember, that the banshee isnt' a woods bike. Ify ou want to run competitively in the woods, you won't be able to do it on a stock chassis'd banshee. It is like riding a bulldozer, when everyone else is on a skid-steer.

 

a lighter flywheel will allow your engine to get in the powerband quicker with the faster revving engine, but.... its a two way street, the engine revs will fall faster and you'll be off the pipe when you wanna be on the pipe." Does that make sense or not ?

 

In my mind, (and i don't build banshee motors either, so keep that in mind) falling off the pipe is an ill fated concern, and one that doesn't hold any weight. I would want my engine to start decelerating when I let off the throttle. Not keep me moving....... When I was racing, I was either on, or off the throttle. And when you do let off, who cares where the RPM's end up, you can pick right back into the powerband instantly. It is of no concern to me. I will never forget when Fixitrod took my bike for a ride. now, keep in mind that he has a stroker. If I remember correctly, (this was at Coalfest) his exact words were "holy shit!!!" And he had a grin across his face. My bike is stock, but feels like it has much more power, and is more rider friendly. CRISP is the only word that comes to mind. A linear connection from the carb(s) to your brain. You think, I need RpM's, you crack the throttle. With a lightened flywheel, there is NO delay. It is there. And when the engine wanted to bog, (like being in too high of a gear), it seems to me that the engine spins up and out of the bog faster, than it would/did with a stock flywheel.

Boon, how much do you charge for your flywheel shavin' service ??

Do you shave off the maximum amount of material as possible, or is there a "sweet spot" that you shave to ?

 

I PM'ed you a price, and I remove as much as possible, without compromising the integrity of the flywheel.

do you notice that when you let off the gas that the bike slows down quicker?

[boonman]

Nope, bike doesn't slow down quicker.....
