johnson2011 Posted December 5, 2011 Report Share Posted December 5, 2011 so i rejeted my shee for winter and put 280 mains in it with stock piolets and stock air screws and everything for now. but it was too warm to test the new jets cause the top end was super boggy, so i let it sit for a while then tried to start it again when it now is cold outside bout 20 to 30 degrees F outside but the dam thing wouldnt start. so im like wtf and went through the carbs everything seemed to be fine in the synched them and tried it again nothing checked the plugs they were wet so i thought maybe fouled so i kicked it over and the both plugs sparked like a son of a bitch. so as a last resort i shot a small amount of either in the carbs and the bitch fired right up. but wont stay idling i drove it around and the topend felt great but as soon as i tried to stop i had to keep giving her gas otherwise she would die and i would have to give another shot of either to start her back up. i compresion tested her and it was about 95 psi on both sides, im lost need help thanks!

fastbanshee8 Posted December 5, 2011 Report Share Posted December 5, 2011 Time for a new top end. At about 100 psi, it's time to rebuild them. Quote Link to comment Share on other sites More sharing options...
johnson2011 Posted December 5, 2011 Author Report Share Posted December 5, 2011 Time for a new top end. At about 100 psi, it's time to rebuild them. alright dam it was hoping it wasnt that, i kinda figured it might be thou. im gonna have it retested thou cause i was using a old ass tester that didnt exactly work right. i had it without an air box on too if that matters at all for those stock piolets and screw settings trying to start it.

fastbanshee8 Posted December 5, 2011 Report Share Posted December 5, 2011 You need to put in some 27.5 pilots, if you're still running the stock carbs. A lean pilot will make for very hard starting. Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted December 5, 2011 Report Share Posted December 5, 2011 On comp test Wide open throttle, kick till gauge stops moving. Plug adaptor must be same length as plug threads. Did you set float heights? What jets were you running before and did plug chop show it was good? Are you talking air box lid or whole air box? Decide how you want to run it and tune for that. When you get back at it start with new plugs. Be sure you have float bowls on correct carb, they are different. Be sure crossover tube is on and slides are in correct carb. Reclean carbs and be sure you can blow air through all passagesl. What did plugs look like from summer riding? Quote Link to comment Share on other sites More sharing options...
