two questions while doing my top end?!?!

Recommended Posts

does a boost bottle REALLY increase throttle response and low end power? i figure just jetting my carb right with jd jetting would do the trick, would this have any type of "boost" :applause::thumbsup: or :applause:

also,

ima been ordering a new head from rhc later in the day i was just wondering. i understand the shim calc on the form here and how to REshim a valve*havent done it yet :applause: * but if i have these new SS and spring kit with a new head....what the heck am i suppose to put in for shim? or is there something im not understanding cause i havent done my top end yet? :ride:

just put in the shims that you already have and assemble the head. once it is all back together, shim the bike and do the calculations for the correct shim thickness. also, i think you should be fine with just the jetting kit.

it might be tight though, and if it is tight (.000 clearence) after your reasemble buy a .006 smaller shim, and if that is still .000, then buy the next .006 untill you get some sort of clearence

even if it is tight you can use the formula t find the shims you need
