DuneRoller Posted January 3, 2005 Report Posted January 3, 2005 I did a search and couldn't find anything that helped. This weekend my Shee started acting up. The left cylinder does not fire in the midrange. It is fine at idle and at full throttle, but if you just want to cruise, then the left cylinder stops firing. Hit the throttle a little more and then it starts firing, backfires the unused fuel and runs ok. I cleaned both carbs very well, changed plugs, switched the plug wires (no change), eliminated all the TORS switches, tried different fuel. Nothing changed it at all. Oh, it has a Ricky Stator adjustable timing stator in it. I moved the timing back to 0 just for testing and that did nothing also. HELP! Quote
Ducman Posted January 3, 2005 Report Posted January 3, 2005 Did you check that the carbs slides are in sincronization? One would have to be out quite a bit to run like that but its possible. Are both needles on the same clip position? Are both carbs getting adequate fuel flow from fuel lines? Air leaks in manifold or around reeds? Broken/worn out reeds? Throw in new plugs? I've had old plugs look good but run bad, usually miss in higher rpms though. Is there rust/crud in the spark plug boots, might cut outperiodically or with moisture. Check compression in both cylinders? Quote
DuneRoller Posted January 3, 2005 Author Report Posted January 3, 2005 Checked carb synch and that is good. New plugs, not used ones (I know that doesn't mean it couldn't be bad so I tried another one to be sure), inspected the carb boots and intake manifolds. I looked at the reeds, but didnt change them because I didn't have access to new ones. Fuel flow is good. I changed all line over to that Tygone (sp?) line. Thanks for the suggestions. Keep them coming. Quote
Bansheerider29x Posted January 3, 2005 Report Posted January 3, 2005 I would say check your reeds, i had the same problem and thats what mine was. Quote
compose2 Posted January 4, 2005 Report Posted January 4, 2005 (edited) check your air filters. my shee had air filters on it that weren't feeding enough air to the carbs. made it run on one cylinder until i was at open throttle. find somewhere clean and dry to test and run your shee without an air filter. see if that helps. if it fixes the prob, just by new filters. by the way, what kind of filter are you running?

compose2 Posted January 4, 2005 Report Posted January 4, 2005 banchetta is right. reverse the plug wires and if the right side cylinder doesn't fire instead of the left, then is an electrical prob. if the left one doesn't fire like before, then its not electrical and should check air/fuel delivery Quote
DuneRoller Posted January 4, 2005 Author Report Posted January 4, 2005 I did switch the wires and the mis/dead cylinder stayed the same. The air filter was freshly cleaned before the trip but I will try with the air filter off (Uni 2 stage filter) and take a closer look at the reeds tonight hopefully. Quote
DuneRoller Posted January 9, 2005 Author Report Posted January 9, 2005 Ok. I took a look at the reeds and they look brand new. No cracks, breaks, or bending at all. Quote
FIRST BANSHEE Posted January 9, 2005 Report Posted January 9, 2005 before I rebuilt my topend my left cylinder compression was lower than the right and my left cylinder was actin the same. I ran a hotter plug in the left side untill I had the cylinders done. br7es in the left and br8es in the right. worked for me,this was a banded not a fix... Quote

We leaned the needle to solve a problem like this before. Quote
DuneRoller Posted January 11, 2005 Author Report Posted January 11, 2005 Thanks guys. I'll keep checking... Quote
NEVER SATISFIED Posted January 19, 2005 Report Posted January 19, 2005 Thanks guys. I'll keep checking... 304812[/snapback] SAME THING HAPPEN TO MINE IN THE DUNES, FOUND OUT HAD LOW COMPRESSION IN THAT FAILING CYLINDER. WENT HOME AND REDID THE TOP END, AFTER I HAD CHECKED THE NEEDLE CLIPS, THE CARB SLIDES, THE JETS, PLUGS FILTERS, BLAH BLAH BLAH... BIKE RUNS LIKE A CHAMP NOW. THIS WAS MY LAST RESORT. Quote
SDD Posted January 19, 2005 Report Posted January 19, 2005 Pull the pilot jet out of the carb having the back firing issue and hold it up to a light. You probably have a grain of sand or other crap plugging it up. Quote
Yunggunnazracing Posted January 20, 2005 Report Posted January 20, 2005 When u took the carbs off and put them back on, did you make sure you hooked up the Choke hose, i did that yesterday. I jetted mine after i added RDZ drag pipes and i left the choke hose off and the right cylinder was misfiring and spitting flames out and it was the choke hose. Its located on the intake side of th carbs near the bowl, it runs from one to the other, try that. Quote
