Bansheeman1121 Posted October 16, 2004 Report Posted October 16, 2004 Mine soundsto be doing the same and i have narrowed it down to the crank seals Quote
Shee_Man Posted October 18, 2004 Author Report Posted October 18, 2004 Wow, sounds like it could be anything. All of you guys who had this problem... you mean by putting on the choke the left side would start to fire again? Even the coil problem? Also if my crank seals were starting to go or I have an air leak to the extent that it won't fire unless I choke it while idling... if I do a plug test, should my left side be much leaner than my right? Or at WOT is the engine not able to suck more air through the hole since it's moving such much more? Quote

It could be many things. you've got all good anwsers,hope one of them helps you. have you check your reeds, maybe flip then, or replace them. A reed staying open will cause that cylinder to have low compression and not want to fire down low. Quote

A reed staying open will cause that cylinder to have low compression and not want to fire down low. Yup... I swapped the reeds from left to right cylinder and the left still wont fire except when choked. It's this "choked" thing that makes me sure it's an airleak or crank seal. However if it was a crank seal would I already have melted my engine... I mean if it won't even idle on that side without choke wouldnt i melt the piston in 10 minutes of normal riding... which i've done way more than like this already. does more fuel help fire low compression?

FIRST BANSHEE Posted October 22, 2004 Report Posted October 22, 2004 have you done a compression check, haven't seen those numbers yet. Quote
Shee_Man Posted October 22, 2004 Author Report Posted October 22, 2004 bought the gauge... only problem is that it looks like I cant thread it in with the gas tank on and I was in a rush at the time... next time i'm out in the country I'll do it. Another idea I had was... could it be crappy sealant on my case halves or a hole in the sealant... or would this affect both pistons... the crank was just changed with 10 hours of riding on it... so I doubt it's the crank seal... everything else looks pretty tight and sealed up when I checked. Also could it be my float height is set too low in that carb? Would that cause a lean condition? Quote
BitchenBanshee Posted October 22, 2004 Report Posted October 22, 2004 Am I wrong, or would a air leak in the case affect both cylinders???? I would think a crank seal would cause problems with both cylinders! Quote
J-Madd Posted October 22, 2004 Report Posted October 22, 2004 It wouldn't likely be the coil, or anything electrical b/c when you swapped plug wires, the same side had the problem (correct?). Could the fuel line be stopped up? Also, if you had access to another set of carbs, I would put those on and see if it fixes the problem. I had a problem that occurred at high rpms I fought with for 4 weeks. Swapped electrical parts w/another shee, re-jetted about 50 times, etc. Didn't work. I put my stock carbs back on and it ran fine. Quote

A bad crank seal on the clutch side will suck oil and foul the plug, a abd crank seal on the ststor side will usually run lean Quote
