Welcome to the forums.

 

well thanks guys!! just wondering what mods work on these and what doesnt. i have full fmf exhaust and k&n filter but no jetting. i have a reed spacer as well but havent tride it out yet.

 

this sounds like it would be right up FtWFLH alley's on the scrambler.

 

Welcome Mstg7993,

I bet these guys will have you running lead holeshot on your scrammy in no time! ...8-)

Cheers,

thats a good start for mods, reed spacer will help out, putting the exhaust and the air intake on will help, definitely will need to rejet though so you don't blow it up, bored out or flat slide carb would make it run a lot better, high compression, porting, and you can do a lot of clutch work depending on what you want. ie: eye watering speed or arm jerking low end

 

Welcome to the forum!!

 

You rally need to jet and clutch to that pipe.Jetting you should start around a 260 and drop down until the plug burns light brown.Clutching I would try a Polaris brown primary spring and either a Aaen blue or HPD violet run stock S55 weights

 

should i leave the pilot and needle stock? ive always heard the real power mods are in the clutch
