MatHolland Posted June 7, 2010 Report Share Posted June 7, 2010 alright..anyone lol. i really want to get my shee up and running...when i first got this banshee it had a bad stator... I put a new stator on it, ran it down the road, and it blew a head gasket...put a new head gasket on stock head..before i did anything else, i did a compression test...it needed a rebuild...so i rebuilit the top end and now both cylinders have equal psi. i went out to go down the road and it didnt seem right...changed the plugs and went down the road still no go..it was cutting out a little, and seemed like not all the power was there...so i came back to my house, pulled the plugs and the one on the right side looked like it was really lean..320 mains in both sides and left side is fine..the plug is burning down at the bottom, but at the top its still white...i put new plug caps on it...checked for a spark and getting good spark. its smoking from both sides..but it dont run right..still cuts out if you pin the throttle....im out of ideas..carbs clean, jets are clean...revs up if you pull the throttle on one of the carbs at a time.. things ive tried...new plug caps..put timing back to stock..cleaned carbs thurouly....replaced choke tube....pulling on the throttle cable 1 side at a time and it revs up...reeds are fine..has a new stator.... mods...toomy exhaust, k&n pods, adjustable timing plate (set at stock right now), 320 mains, 25 pilot, tors eliminated, stock head shaved i guess because it has 180psi at 400ft above ground level.

TNTS355 Posted June 7, 2010 Report Share Posted June 7, 2010 Sounds like you have an airleak. Did you do a leak test after replacing the topend? I know if sounds stupid but even after replacing reeds or boots I do it. Quote Link to comment Share on other sites More sharing options...
MatHolland Posted June 7, 2010 Author Report Share Posted June 7, 2010 definately not the jets. took float off and cleaned the float needle...carbs are in sync..lines are not plugged up coming from the petcock. have not done a leakdown test. probably going to round up the supplies tomorrow and make one, because im not getting anywhere..I sprayed carb cleaner on the intake boots, and didnt notice any change in the idle.

MatHolland Posted June 8, 2010 Author Report Share Posted June 8, 2010 also, my left side isnt really smoking much? my right side is smoking a lot more?? Quote Link to comment Share on other sites More sharing options...

I will still go with an air leak. Keep us posted. Quote Link to comment Share on other sites More sharing options...
spurdy Posted June 8, 2010 Report Share Posted June 8, 2010 Choke tube between the stock carbs. SP Quote Link to comment Share on other sites More sharing options...
TNTS355 Posted June 8, 2010 Report Share Posted June 8, 2010 Choke tube between the stock carbs. SP said he already did that Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted June 8, 2010 Report Share Posted June 8, 2010 you said your still running the 25 pilot jet....try stepping it up to a 27.5 mine was cutting out from idle to mid throttle because the small pilot wasn't able to keep up to the FMF Fattie exhaust. pretty much all aftermarket performance exhausts need to be runnin a 27.5 pilot Quote Link to comment Share on other sites More sharing options...
MatHolland Posted June 8, 2010 Author Report Share Posted June 8, 2010 (edited) how do i find an air leak...i sprayed carb cleaner all around the boots and carb and didnt notice and change in idle...i guess a leak down will tell me where it is exactly? could it be that one of the cylinder gaskets didnt seal or head gasket didnt seal or something? also, everything was fine...the jetting was perfect for that exhaust when i first got it. ive put everything back to how it was since i got it except for the k&n pods...i can pin it wide open everywhere and it still does the same..but i will try to get a pilot a little bigger..i thought pilot was basaically the idle jet.

fastbanshee8 Posted June 8, 2010 Report Share Posted June 8, 2010 What a lot of people fail to realize about the pilot jets is this. They flow fuel 100% of the time, while the engine is running. No matter where the engine is in the RPM range, the pilot jets have fuel running through them. Quote Link to comment Share on other sites More sharing options...

TNTS355 Posted June 8, 2010 Report Share Posted June 8, 2010 Here is a link to build your own leak tester. http://forums.everything2stroke.com/showthread.php?t=16162 I made my own out of pvc, tire valve and a slime pressure guage. If you need me to take a pic of it and send it to you I will. Apply 6psi, no more! Quote Link to comment Share on other sites More sharing options...
MatHolland Posted June 8, 2010 Author Report Share Posted June 8, 2010 I will try getting some bigger pilots..although that would be happening to both cylinders and not 1 right? If you don't care post a pic of the leakdown tester you made. I have saw a cpl different designs. I am wanting to go to the store and get what i need..its raining outside so a good time to do some work in the garage. Quote Link to comment Share on other sites More sharing options...
TNTS355 Posted June 9, 2010 Report Share Posted June 9, 2010 I think the freeze plugs at 1 3/8. The pipe for a stock 26mm is 1" pvc. Quote Link to comment Share on other sites More sharing options...
