Mullet Man Posted April 24, 2006 Report Share Posted April 24, 2006 (edited) EDIT: oops, title is suppose to read "need some direction" not "new some direction" shee started acting up on me last weekend. didnt go riding this weekend because of it. right cylinder is lean. plug was semi white in color. left side is a milky brown (looked good to me). the right side exhaust pipe doesnt kick out as much pressure as the left side does (tell by looking at it and sticking your hand over it). when i rev it up some, it will sputter and backfire a bit out of the right side and run fine for a few moments and then continue like its choking. when i rode it last weekend, after engaging a higher gear, it would stumble for a second and then pick up and haulass (caused me to lose a race with another banshee and a modded 450r ) obviously its getting spark otherwise the plug wouldnt be whiteish... i changed out plugs (BR8ES before and after) just to see if that would help...and it didnt. i took it down to the reed on the right side. because thru searching on here i had read that a torn reed can cause an issue like this...it looked intact and clean to me. no apparent leaks in the intake tract. the choke crossover tube is and was in place have i narrowed it down to a compression test and a carb issue or are there other things i could also be checking? this just came out of nowhere and it ran fine every other time i rode it with no symptoms at all... i run yamalube at 40:1 with 93 octane. any ideas? thanks MM Edited April 24, 2006 by Mullet Man Quote Link to comment Share on other sites More sharing options...
batoutofshell Posted April 24, 2006 Report Share Posted April 24, 2006 make sure the coils wires are tight on the coil black and orange Quote Link to comment Share on other sites More sharing options...
Mullet Man Posted April 24, 2006 Author Report Share Posted April 24, 2006 make sure the coils wires are tight on the coil black and orange 506784[/snapback] spark has to be good, otherwise the plug would be black and carboned up. not whiteish...right? or you just thinking maybe an intermittent issue with the spark firing? after tonite, i wont be able to respond until this coming weekend...

Mullet Man Posted April 24, 2006 Author Report Share Posted April 24, 2006 (edited) lets see compression reading on both sides please. 506790[/snapback] havent done one yet. i will be doing that next weekend. oh, i also disconnected the TORS box and the switch at the throttle.

dogboystoy Posted April 24, 2006 Report Share Posted April 24, 2006 Either your carb caps have come loose and your air/fuel mix is getting messed up on that carb (happened to me), or you need to adjust the screws on the top of your carbs to balance both sides. That was also an issues I had. Quote Link to comment Share on other sites More sharing options...
Mullet Man Posted May 5, 2006 Author Report Share Posted May 5, 2006 OK, compression test results in ~108psi in both cylinders (bike wasnt completely up to operating temp, only semi warm). i found that when the choke is out, either half or all the way, the right exhaust has the same amount of pressure coming out of it as the left does. when the choke is closed, then the right cylinder is not working properly and you have to give it alot of throttle for it to show the same amount of exhaust pressure as the left side. both reeds look fine and look to be in good operating order. took the float bowl off and removed the main jet, float and fuel valve and cleaned with carb cleaner. i didnt mess with the pilot jet at all tho...could this be part of my problem related to the choke? also checked the crankcase fluid and it is full so i dont think a crankseal is an issue from what i have read about it from searching on here i'm still figuring out this whole carburation thing, so thats where i need direction. any ides about the choke thing?

fastbanshee8 Posted May 5, 2006 Report Share Posted May 5, 2006 Pull the right carb, and clean it real good. Sounds like your pilot jet is plugged, partially or completely. Take out the pilot, spray some carb cleaner in it, and blow it out with some compressed air. Make sure both air mixture screws are turned out the same number of turns, also.

batoutofshell Posted May 5, 2006 Report Share Posted May 5, 2006 I noticed on mine the right side was doing the same thing and I realized I had a bad pingle wasn't getting enough fuel to supply both carbs at idle,I didn't clean it just got a new one for an 87 it was old! pulled the choke same thing because it was sucking from the left to supply both. Changed it out and BRAPP BRAPP ready to rip. Just a thought Quote Link to comment Share on other sites More sharing options...
Mullet Man Posted May 5, 2006 Author Report Share Posted May 5, 2006 i walked both screws in and then backed them out 2 full turns on both carbs. i noticed that the right carb slide moves just a cunt hair sooner (barely barely noticeable) then the left carb does when engaging the throttle. but that shouldnt be anything i would think i need to address. you really have to be looking to notice that at all Quote Link to comment Share on other sites More sharing options...
Mullet Man Posted May 5, 2006 Author Report Share Posted May 5, 2006 BOS; what is a "pingle"? Quote Link to comment Share on other sites More sharing options...
biggun6ss Posted May 5, 2006 Report Share Posted May 5, 2006 Pingle is a type of fuel valve. If you are pulling the choke out and it runs better either you have a clogged jet or you have an air leak. Quote Link to comment Share on other sites More sharing options...
sheefreak Posted May 5, 2006 Report Share Posted May 5, 2006 I am leaning toward the air leak. Anytime you are in the carbs to clean anything, always clean the pilot jets. They are the first to plug. There is a slight possibility this is your problem as you explain that it clears up at WOT. Clean the right carb againa and hit the pilot jet. IF that doesn't fix your problem, better look for an air leak. If your spark plug is white, that side won't last long so be careful. At 108 psi, you may want to think about at least a hone and re-ring soon, if not the whole top end. Quote Link to comment Share on other sites More sharing options...
Mullet Man Posted May 7, 2006 Author Report Share Posted May 7, 2006 well, the pilot jet had one tiny little speck of dirt in it. carb cleaner wouldnt blow it out so i had to take a bread tie wrap wire and clean it. that cured all issues shees back to normal. both plugs are back to a brownish color and all seems well! on the compression test, i didnt warm the bike up but for about 30 seconds before doing it. i think that is why the numbers are low. i'll perform another test next weekend with a good amount of warm up time before hand just to make sure but i'm confident the quick warm up is why the were low. thanks for the help/ideas guys!!
