blaster jetting

[ayron26]

I have a .25mm over pretty much stock blaster except for fmf pipe and answer 2 exhaust, what should i be jetting at and is a 34mm kehien to big for my motor?

around 260 main and no the 34pj wont be too big although it wont really be much of any gain until the compression and porting are imrpoved

[ayron26]

how do you improve compression?

milled head

dont mean to highjack this thread but, i am about to have my bike ported polished, and take about 20 thou off of the head + get boyeson reeds. 260 main was perfect before, but what about now? also will i have to run racing fuel, or just the 93?
