fastbanshee8 Posted January 25, 2006 Report Posted January 25, 2006 I got out my Clymer's manual, and it says to check the pickup coil, which is the little black box that sits behind the flywheel. You might want to clean any rust off the flywheel pickup points, while you have the cover off. If everything is good there, then check the wiring harness for shorts or breaks, and check all of the plugs, and make sure they are clean and making good contact. If all of this stuff passes, and the carbs are clean and adjusted correctly, then the CDI box is faulty. All of this is according to the manual. Quote
J-Madd Posted January 25, 2006 Report Posted January 25, 2006 If you swapped plug wires and the problem stayed with the left side, It almost could not be electrical. You said you checked the boots, but did you actually check the reeds? A broken reed on one side would cause a similar problem. Also..I have had experience with the same problem on a buddy's shee. Cleaned carbs, checked reeds, etc. I finally gave him my spare left side carb and it fixed the problem. We never did find out what was wrong with the carb. It looked fine. Quote
biggun6ss Posted January 25, 2006 Report Posted January 25, 2006 When you put the carbs on do you check to see if your slide is setting properly? Are the jets the same size on both carbs? Did you adjust your air screws the same on both carbs? Did you check your reeds for any damage? Quote
brilei5 Posted January 26, 2006 Report Posted January 26, 2006 J madd is correct. If you swiched around the plug wires and the problem stayed on the left it cannot be ignition. If it were it would follow the bad wire.It is probably NOT the air filter that should effect both sides unless you have individuel clamp ons. I would swap carbs first then reeds. You will need a longer choke tube for the test. but they will swap. If its not spark and its not air it HAS to be Fuel related i.e. carb reeds Quote
blueshee03 Posted January 26, 2006 Report Posted January 26, 2006 is it loosing spark or getting that much gas in the cylinder that its drowning the plug?if your running stock carbs do you have the float bowls switched from carb to carb?they are different i do believe.if they are aftermarket carbs have you tried switching carbs from side to side? Quote
Infamous039 Posted January 26, 2006 Author Report Posted January 26, 2006 (edited) I have switched out 3 different carbs on that left side and no change. I also have installed a brand new coil and still no change. I checked the reed for damage and they looked good, cleaned the carbs again and checked the float. I believe if it was a stuck float the gas would run out of the overflow but it doesnt. I am running a 280 main jets in the bike. The gas is drowning out the spark and the left side weakens. I thought it could have been an electrical problem with my harness or CDI. When I unplug the right side spark plug boot and start it, then the left side runs good, but when I plug both of the spark plug boots up and start it, then left side weakens like its losing spark. I have the pickup coil set at 0.018 and still no change, also installed a new Woodruff Key.What the heck is an Overhaul??????? Also will a 1991 harness fit a 1995 CDI box???????????

fastbanshee8 Posted January 26, 2006 Report Posted January 26, 2006 Sounds like your stator might be getting weak. Quote
jury Posted January 26, 2006 Report Posted January 26, 2006 hey im having the same problem ...that did that untill a bearing went out in my crank and shattered. that engine had a brand new stator.. now i have a brand new engine and the same thing is happining. when i first started it it ran ok on both sides then the left died like before, i have switched the coil boots and the carbs and its not any different. i got a new cdi box and im going through all the wiring. if i do something that fixes it ill will let you know. good luck Quote
Infamous039 Posted January 26, 2006 Author Report Posted January 26, 2006 If you repair yours please let me know ASAP Quote
ogre03 Posted January 26, 2006 Report Posted January 26, 2006 you said you checked the reeds and they looked good. Did you try actually swapping sides with the cages? since you keep tearing it apart anyway next time try switching sides when you throw it together. Sometimes it's hard to see problems with your reeds, it's best to just swap sides to rule it out. Quote
Infamous039 Posted January 26, 2006 Author Report Posted January 26, 2006 OK I will try that, but I just installed new reeds and a new reed cage and no change but I will swap them out and see what happens. Quote
bigboybanshee Posted January 26, 2006 Report Posted January 26, 2006 When was the last time you checked your compression? Quote
Infamous039 Posted January 27, 2006 Author Report Posted January 27, 2006 (edited) I checked my compression 2 days ago and both were at 120lbs then I checked it again yesterday and it read 90lbs, I will check it again and see what happens. I dont know if its from all the gas thats fluiding the cylinder b/c it should change from day to day without me riding it. The bike starts on first kick, before the recent problem the bike ran flawless and strong. I just cant figure it out and I would hate to take it to the dealer and get raped by them.

bigboybanshee Posted January 27, 2006 Report Posted January 27, 2006 Don't take it to the dealer!!!! Have you done a leak down test, to see if your crank seals have gone bad? Quote
