91coupemike Posted January 20, 2015 Report Posted January 20, 2015 Banshee has ran great and gives me no issues until the other day, went wot and it lost power and popped a few times out of the exhaust. It runs fine into the band a part throttle but once you go wot it feels like it's running out of gas. This happened after I filled it up, the fuel level was about 1/2 inch from being "topped off", put a little too much. Could it be vapor locking the fuel cap vent? It's an alba racing cap with thier short vent. Would that cause this issue? Just took the carbs apart and pulled reeds, all looks good. Going to clean them up real nice and try it out. Plugs looked fine. Any suggestions? Quote
sheerider1026 Posted January 20, 2015 Report Posted January 20, 2015 Cold temps/air will lean it out. Try bigger main jet and see if it helps Quote
91coupemike Posted January 20, 2015 Author Report Posted January 20, 2015 It was running fine in colder weather, this was actually warmer then lately, was 70* out. Don't really ride it of its less then 50 out anyways. It was just running like the fuel was turned off and the bowls we're going dry. Quote
Larry's Shee Posted January 20, 2015 Report Posted January 20, 2015 When was the last time you cleaned the petcock/filter ?? Quote
91coupemike Posted January 20, 2015 Author Report Posted January 20, 2015 Never! I'll give it a go too. Quote
Larry's Shee Posted January 21, 2015 Report Posted January 21, 2015 Is fuel fresh? Check that the float bowls don't have gunk built up from evaporated bullshit eco gas in there. Shit looks like jelly, dries up and turns to powder. Quote
91coupemike Posted January 21, 2015 Author Report Posted January 21, 2015 Fuel is a few months old 104 sonoco with redline premix. Jets did have some powder build up but not bad, they're soaking in Chem dip right now. The floats looked good, I did have fuel in the over flow hose, so I'll reset them as well Quote
91coupemike Posted January 21, 2015 Author Report Posted January 21, 2015 I'm kind of stuck on the fuel tank being over filled, does that happen? Waiting on new reed gaskets to get it back together and do a leak down test although my thinking has me to believe If it were an air leak issue the extra fuel from wot should have made it run better instead of great part throttle and lousy wot. I've ran my banshee out of gas once a few months ago and it felt identical to this. I'm running br9 plugs as well, should I go to a br8? Not related to this issue but j/w. 353cc, stock stroke, .020 over piston, stock reeds, pwk 28, pods, t5s, coolhead 19cc, matoon timing plate @ +4. 138 main and 45pilot. Starts great unless it's below 60* outside, otherwise 1 kick with the chokes pulled will get her going. Bike runs good imo, ran a few cars/bikes that run high 8sec 1/8miles and beat them in a race launching in 2nd to keep the nose down but they come around me in the top end of 6th, stock sprockets and 18in tires.

Larry's Shee Posted January 21, 2015 Report Posted January 21, 2015 Have you ever done a plug chop or read the plugs with the correct plugs? Quote
91coupemike Posted January 21, 2015 Author Report Posted January 21, 2015 Correct plugs? I went out and ran it and pulled the plugs, they looked decent but I didn't have a way to cut the threads off so not a "chop" Quote
91coupemike Posted January 29, 2015 Author Report Posted January 29, 2015 Finally got it all buttoned up and she rips again. Never found anything wrong with it besides draining a bit of gas out and resetting my floats. Carbs are slightly out of sync but I went for a test drive and its running good. Quote
