TN BANSHEE Posted December 31, 2011 Report Share Posted December 31, 2011 Hello. I bought a banshee a couple of months ago in pieces and rebuilt engine. Never heard it run before i bought. Bored one size over, trinity 2 into 1 carb, toomey pipes, no air box lid. Engine starts after a couple of kicks and runs okay. It will not peak. It just hits a certain point and stays there. I read on here to cut the green/yellow wire to cdi box for parking brake and un plug tors box. Did that and no difference. I have jetted from a 160 main tIa 225 main. No difference where i move the jets to. 1 time it peaked on me with a 185 main in it and kind of scared me but when i let off the throttle it back fired and died. Then would not start for around 3 minutes. When it did start it ran only on 1 cylinder. I pushed it back in garage to start checking spark and then started it and it begain running on both cylinders but never agian would peak. I am not familiar with 2 strokes like i am with 4 strokes. This is my first 2 stroke so any help will be appriciated. I ordered a new coil and cdi box tonight to get me started in the right direction hopefully . Thanks Quote Link to comment Share on other sites More sharing options...
Phelps Posted December 31, 2011 Report Share Posted December 31, 2011 have you tried pulling the choke while riding to see if it helps? did you leakdown the motor to make sure you got it sealed up good? a clean bog is signs of being lean. if it's a rough bog and smoking a lot it maybe rich, but doesn't sound like it.

robert0762 Posted December 31, 2011 Report Share Posted December 31, 2011 Make sure you check the gap on the pickup. Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted December 31, 2011 Report Share Posted December 31, 2011 I heard of engines bogging when the pistons are in backwards. But I think is almost to the point where it just barley runs Quote Link to comment Share on other sites More sharing options...
TN BANSHEE Posted December 31, 2011 Author Report Share Posted December 31, 2011 I never did a leak down. But I put new crank seals in. I live in Crossville, TN. The thing that gets me is it peaked one time and ran awesome when it did. I put jets back to exactly that again and nothing. Quote Link to comment Share on other sites More sharing options...

Start with a compression test and then do a leakdown test on the motor. Then run down a list of EVERYTHING that is done to your bike and report back....

dillbilly Posted January 2, 2012 Report Share Posted January 2, 2012 x2 on keeping it simple. Don't know how many times I overlooked the simple stuff. Quote Link to comment Share on other sites More sharing options...
TN BANSHEE Posted January 2, 2012 Author Report Share Posted January 2, 2012 (edited) Well I think I am gettting somewhere now. I forgot it had adjustable timing. I started reading about adjustments on it and i had put it exactly how i took it off at -7. Read on here it should be +4 or +5. i adjusted it and started up awesome and sounds totally different. took it out for a spin and started peaking but could tell i had the wrong jets in it. ran around and peaked out 5 or 6 times just having a little fun with it and then started backfiring and died. No fireright now. it is just like the first time it peaked and then died. i am thinking it may be a coil or cdi getting hot now and loosing spark. maybe the timing will fix my peaking out after jetting it. I waited about 5 minutes after it died and fired it right up first kick. Edited January 2, 2012 by TN BANSHEE Quote Link to comment Share on other sites More sharing options...
