Banshee Jetting looks Lean, but is running rich?

[Badapwned]

I'm glad I could help someone. Also, I couldn't agree more about people not finishing the thread with how they fixed their problem. It should be absolutely mandatory to finish your thread to help people in the future.

 

Update:

 

Well gentlemen, today was the day to let my G/F ride it. She did good, I was afraid she might get hurt or do something...well stupid.... lol, but she did great. She hasn't had much experience with a quad, let alone a clutched 2-stroke quad, so I'm very pleased.

 

I put in the 25 pilots and 320 mains this morning. The 25 mains really helped with the bogging, it revs much easier now. It just requires some fine tuning.

 

I do have one concern, I have never been on a "well tuned" banshee, or any banshee for that matter, so I am kinda peeing in the dark if you know what I mean. I know what a 2-stroke is suppose to be like, but I am definitely on a steep banshee learning curve. I got a great comment from some guy today, he said I sounded like a "Hot Snowmobile", made me get the warm fuzzy's inside hahaha.

 

My next plan: Wait for my new jets to come in. Put a bigger main in and finally try some fine tuning.

 

I am bringing the whole crew with me tomorrow to go riding, my father, G/F and my sisters. Hopefully we can all have a good time.

 

 

 

P.S. Gas is cheap, they are giving that shit away, I could almost sop it up with a biscuit.

 

 

I will update with how tomorrow goes, stay tuned :biggrin:

Update:

 

Went with the family to the usual place and had a great time.

 

My sisters, which by the way have never ridden anything with a clutch, did a great job. They were able to hop on the shee and cruise around with me.

 

 

The low RPM bogging is almost gone, but I can still tell it is there.

 

Im kinda stuck right now without anymore jets. The ones I ordered have not come in the mail yet.

 

The time it takes to get to the powerband is still the main issue.

 

BTW, I would have to strongly disagree with anyone that says the banshees have to be like a light switch, either on or off.

 

My opinion is if that's how someone's banshee is then its not jetted correctly.

 

When I bought this banshee that's exactly how it was, the motor was either in the PB or barely went anywhere.

Its at least 100 times better then when I bought it, not to mention the guy had a 270 main in, and im already at 320 needing to go bigger.

 

 

One other concern is my pilot jet size. Anyone here with just some pipes uses a 27.5, here I am with pods, pipes, ported cylinders etc, and no way in hell am I putting those 27.5's back in.

 

My air screw may need some fumbling around, we will see how that goes.

 

When I get my jets in I will let you guys know what I come up with.

 

Any comments on my pilots guys?

Update:

 

 

So, I was working on my bike last night, syncing the carbs, and messing with the air screw.

 

I decided to give it a compression check, just for the hell of it.

 

I get 110 PSI in both cylinders, so I am like WTF. What the hell happened.

 

So, I call the guy up who rebuilt my motor, told him what happened, he said to bring it up to his place.

 

So last night around 8:30, I drive to this guys place, etc etc.

 

He did a compression check and got around 150 PSI on one side and around 145 PSI on the other.

 

Conclusion: Don't buy cheap pressure gauges from Murry's or Advanced Auto Parts. Nuff Said.

 

 

So, after that little ordeal was settled, I was telling him how I was having trouble jetting due to the fact my pilot jet was the smallest one I could get and still could not get it lean enough,

 

 

So, he asks me "are your slides in backwards?", I reply back, erhh dunno, I haven't switched them since i bought it from the guy. So he checks, and yes they are in the opposite carbs.

 

So at this point, my whole night is a bust, but, you live and learn. So anyways, switched the slides around, through new plugs in and she fired up.

 

 

He told me when you have the slides in backwards, since they are tapered or cut on one side, it always exposes the pilot jet, meaning it was ALWAYS dumping gas in, so that's the reason I couldn't get it jetted to save my life.

 

 

So, im happy once again.

 

 

I am going to rejet it tonight and take it for a ride.

 

 

Ill let you guys know how it goes.

Ill let you guys know how it goes.

 

25 pilots should be fine anyway, I can't believe it even ran as good as it did with the slides in backwards, otta scream now!

Update:

 

 

Put new jets in, again and again and again....

 

I started off at 25 pilots, 320 mains.

 

 

I am now at 32.5 Pilot, 360 Main, Need Clip Third Notch, Air Screw ~ 1 turn.

 

 

At this point she barely even smokes, I am going to have to order bigger mains, I would have never guessed.

 

 

360's are pretty big jets right? The banshee sucks that gas down and loves it, no bog what so ever at the top end, the bottom end bog is finally gone.

 

 

Im thinking it could use 380 or 390 mains.....considering the way its going now. Who would have knew.......

Update:

 

Went riding today,

 

The banshee is still lean, I dont get it. Just from reading what other people have done to their banshees and what I done to mine, it seems like I would have been done a few jet sizes back.

 

The pilot is to small, its a 32.5 with air screw at one turn, when I pull the choke the bottom end is alot better. So, I am going to put a 35 in tomarrow.

 

The main is to small, when I do a pull and go through the gears, pull the plug, its a very light color, its not even getting brown. So, I am going to pick up bigger jets tomarrow. I will probably throw the 35 in and put in the 380's and see what happens.

 

I am going to silver lake this weekend, leaving tomarrow.....Stoooked as HEEEElllll@@@!!!!

 

BTW, ITS FRIDAY BITCHES!!!!!!!

 

 

I will let you guys know how it goes when I get back.

Update:

 

Just got back from my trip from Silver lake. To say the least, the dunes were closed.......funny right?

 

 

All is well, we went north west about an hour to find some amazing trails, not only were they perfectly smooth, they are endless. Very fun.

 

If anyone has not experienced this type of riding I would highly recommend it. It was the called the "little O Loop" and "Big O Loop".

 

 

Anyways, I went to my local motorsport store to pick up some bigger jets real quick, I picked up 370, 380 and 390's.

 

 

I did have 360's in, to say the least I was not getting any color on the plug. I skipped right over the 370's and went for the 380's.

 

I also put in the 35 pilots, which helped considerably with the 1/8 throttle bog. The air screw is still about 1 turn out, I did not adjust it from the 32.5's yet. I will work that out soon.

 

 

The 380 mains were a good size, I got the brownish color on the plug I was looking for, good power and no bogging at the top end. Lots and Lots of power.

 

 

So, the only issue I got left is around half throttle, its wants to break up, the engine is breaking up, not sure what this would be caused by. I thought maybe it was getting to rich and it was trying to clear itself out, so I moved the C-clip to the leanest position. But it did not change the break up enough for me to notice. I will move the C-clip the other way to the richest position to see if it helps.

 

 

Anyone got any input on engine break up? Is it a rich or lean condition?

 

 

Also, hopefully someone finds these updates helpful. I will stop if you guys are getting bored of my saga! lol
