[QUOTE="jason33, post: 1190999, member: 73168"] did you jet it?- you changed the exhaust- that changes the back pressure on the cylinder, higher compression = more atomized air to fuel- it should start easier what does the plug look like- black,and dry= not enough air- wet -too much fuel if the float level is too high, the fuel will run into the cylinder when tipped this floods bikes do you have to choke the hell out of it when you first start it? if so a size bigger pilot will help- if its jetted - it might be too rich- this might be the problem - since you said it has all kinds of stuff done to it- it sounds like someone else did all this stuff??? not you?
