Springtime Mods

[kamp0ss]

Alright so spring is right around the corner and the Banshee is getting ready to hit the trails. As much fun as I has last fall riding, as a first time banshee owner, it is time to do some new mods for the new season. I have done a lot of research the past couple days to see what else I can do without taking the engine apart and doing all the expensive stuff. I'll list the different things I've considered, so that you guys can hit all the points and help me out. Some are noobish questions, but it is only my second season with a banshee (not counting winter) so go easy on me

 

Here's what I already have done to my shee. Pro Circuit Pipes, Vforce 3 reeds, it has been jetted, I think I have pro-designs air intake, but I don't know what the stock looks like, so I'm not sure.

 

I really just want to get more noticeable power before I start taking the engine apart, but here's what I want to do, or am not sure if it is worth doing... please tell me what you guys think is worth doing, not worth doing, or anything I missed that I could do to get more power.

 

 

1. Shave the heads - From what I've read .040 is a good amount before going to race fuel. It's fairly inexpensive, and people suggest this is the next step after reeds and pipes. My cousin said to get a new cranks before you do this.

 

2. 2-1 Toomey Air Filter - I read somewhere this is better for airflow, but you will have to adjust your jetting if you do this. I mostly ride trails and sand pits, is this worth doing, or will it suck in the sand. I am 80% sure I have Pro-Designs air filter right now, which do you recommend? I also saw that you needed to move your coolant if you get this. I also saw a K&N filter lid that was supposed to let in more air too, if I were to keep the box I would consider this method, what do you think?

 

3. Boost Bottle - My friend says its good for throttle response. But 90% of people say its just looks and is garbage.

 

4. TORS eliminator kit - Can someone please explain this. I see it everywhere, saying that it is a must do for banshees. Can someone tell me how to check if it has been done, or not. I also read you need a Kill switch if you do this. Is it worth it, what are benefits?

 

5. Bigger Carbs - I heard these were great if you planned on upgrading your engine later on or just staying the same, but I also heard they were pricey. I would rather do a couple cheaper things than buy one large mod, but if it is worth the money I suppose I wouldn't mind looking into it.

 

6. Cool Heads - I really didn't do too much investigating on this, but I've seen a lot of people have them. I can kind of guess what they do, but what do they do exactly?

 

7. This is not a product, just a question. I did 32:1 mix last fall but I was smoking my cousin out big time lol. What mix should I try next to get rid of the smoke and make it more lean I guess...?

 

 

So as you can see, I have ideas, but no direction as of now. Any help is great, and if someone can tell me what order things should be done, that would be even better!

 

Thanks all.

First off welcome to BansheeHQ!

 

1: As far as head mods go, you can either buy a cool head and correct domes OR have your stock head milled. Me personally I run a Noss Cool Head and love it. Just really depends on how much your budget is.

 

2: If you don't see much water I prefer ditching the entire air box and running open k&n with outerweared pod filters for maximum air intake. If you do see the occasional puddle you could possibly suck water having it set up this way just fyi.

 

3: Boost Bottle= Trust me, the stock intake tube works just as good and boost bottles can possibly crack your intakes resulting in an air leak.

 

4: IMHO getting the TORS off the bike should be a priority. Look on top of your carbs, if there are big ugly boxes on top then you will need the removal kit. If there are caps with your throttle cable coming out of the top and it looks clean and neat...your TORS should be gone already.

 

5: Honestly, right now I wouldn't waste your money on bigger carbs. Stock carbs will run well up too 70HP and I promise you won't be reaching that until your ported or running a 4mil crank. I still run stock carbs on my Aggressive Dune Ported stock stroke and it rips hard.

 

6: Read answer 1

 

7: I've always ran 40:1 Klotz R-50. You may need to check your jetting and do a plug chop.

 

There are some great members on here, I'm sure you'll have some good mods to consider and everyone will have there opinion on your questions.

 

I would recommend calling a site sponsor on here to order whatever you need.....I always use Wildcard Racing and they are great people. But any sponsor will be awesome to work with, just personal opinion.

i think zilla pretty much got it all. the only things i have to add are if you still just want to mill the head i would do about .030 to be safe. Cool heads are pretty and the removable domes are nice but the simplicity of the stock head cant be beat. especially in the realm of simple and cheap mods. A timing plate set at +4 is a decent addition as well. I picked my timing plate up from here on BHQ for $30 used a couple years ago.

[Larry's Shee]

One of the site sponsers rechambers and mills head for $80 about. Don't recall who, just clic on them. Timing plate is a good mod, sticky on how to do it yourself. Also change trans oil. Do a search, do not start a thread on which frigging oil do I need.

MULL engineering sellls the shaved and rechambered head for pump gas, for 85 $$.. im thinkin about ordering one for myself..

[derekr8885]

Jimat passion racing engines rechamber and cut my head for the 4 mil...awesome work

[kamp0ss]

1. have the head domes cut. this will give more power than just shaving.

2. not really worth doing, a pro design with k+n filter is good

4. TORS is good, to check, just look at the top of the carbs, is there a box on top of them?

7. i run 40:1, but what kind of oil do you have? get a good oil an run 40:1. if you change your premix ratio, you should check your jetting.

 

- What exactly does it mean to have the head domes cut vs having them shaved? My only worry with getting a ton more power is that I have to change other stuff to compensate for the power and thats just more money I gotta spend.

- Which k&N filter is good for riding trails, seeing occasional mud and water? I know some are good for dirt, some are good for trails, it depends what kind of riding you do.

-I am pretty sure my TORS are done then, cause there is no box on top of them, just chords coming off of the carbs.

- I have been using Castrol 927 oil.

- The milling always confused me, I am a rookie with engine talk. I plan to do the engine work once I figure out how it all works. Right now I just don't know what and when things need to be done. If there was a rookie answer sheet this would be much easier lol. I guess I am just taking baby steps. I have about 300 to spend on upgrades, and I prefer power over cosmetics. I know when you start doing stuff to the engine you gotta change other stuff to compensate for the power, and I dont wanna spend my budget on tuning the engine then have no money to change stuff that needs to be changed to handle all the power. Is this too confusing? I guess what I am looking for from others is a gameplan, such as, you already have this(i.e pipes and reeds), so now your next step would be this and this (i.e milled head and flywheel), and as a result of the increased power you will need to do this (i.e get a better clutch). If this makes sense GREAT! but if not I will try and re-explain lol.

- My cousin recommended the next mod I do would be get a new crank, would this be worth considering?

-Can you explain what +4 means for a timing plate? Does it mean 4 more notches? What exactly will a +4 timing plate do?

 

One of the site sponsers rechambers and mills head for $80 about. Timing plate is a good mod, sticky on how to do it yourself. Also change trans oil.

- That is a good price. What would be the benefits of doing it myself, vs buying a +4 like Coupelx mentioned? My trans oil is fresh, are you refering to changing it if I do the mod on the timing plate?

 

 

 

**Thanks for all your help, I am a quick learner so whatever time you waste on me is going toward a good cause! lol This is all great info, thanks for your help thus far!

Why is he telling you to get a new crank? Like a 4mil? or what?

he said it gives more mid range power. i dont like when 4 strokes get off the line faster than me!

I think it's Jeff at fast...he gave me the same price on a milled head. Real nice guy. He deffintly recommended a milled head and +4 timing plate, he said best bang for buck

What does this go for all together? How much does it add? I was considering sending to herr's and getting a trail port job

Okay he must be talking about a 4mil crank then

[BigRed350x]

Kevin at Herr Jugs Racing can take care of everything you need... Sounds like it will be a good build.

[Larry's Shee]

Be sure to use the proper flywheel puller wether you go adjustable plate or modd your stock (free). It's called a Banshee flywheel puller , not 2-3 jaw gear puller, fyi. Less than $20. Sticky for doing this is at top of this section.

[kamp0ss]

Because the weather has gotten so nice out so fast, I am going to hold off til the end of this riding season. I have decided to get a port job from Herr Porting.
