Alright I am having a tough time trying to jet my carbs correctly. My motor is a 4mil stroker/longrod crank, that has been dune ported, along with toomey t-5s, a cool head with 21cc domes for 66.5mm blaster pistons. There are 38 pilot jets and right now at around sea level and I have tried 148,155,158,162,170,172,and 175 main jets but I havent found the right setup. Does anyone have any helpful tips for me? Thanks![img]i/expressions/face-icon-small-confused.gif[/img]

 

My fault sorry....... I accidently clicked the button too many times!

 

u need to do some plug chops, and it will also help if u have a carb sync tool, farmandsandtoys.com has them 4 50 bucks, any1 who owns a shee should have one.first off warm ur bike up on old plugs, then install new plugs and run at full throttle through all gears thn pull in clutch and hit the kill button, then pull ur plugs out and see what uve got. in order to get it exact u have to cut the side of the spark plugs to be about 2 see the bottom part of the porcelin, what ur looking to achieve is a 2mm smoke ring, which would mean a 2mm section of brown on ur plug if theres too much brown its rich and if u dunt see any brown its lean. heres an example of what ur plug should look like when u cut it open.
