hey guys tried to search this didnt have no luck i have 2010 model bone stock ready to get some more performance, is billblue mikuni tm33 carb way better than a dynajet kit or do the rejet and put the mikuni carb money toward the 351, or do both new carb and 351. crap to much to think about. one more question if i rejet were do i get a 0.018 bit no help from local hardware.thanks for any suggestions.

 

Look to a hobby shop or on-line for the drill bit. Beware of cheap ebay bits.

 

The mod recommendations depend specifically on how much power & where on the power band you want to add the power. Answer these questions will answer your question.

 

Thats the way i would go.

I can't speak to the mikuni carb upgrade but I think i have done all of the other upgrades and the BB351 is the one mod that stands out . ( I'm still running the stock cvk carb )

 

A machine shop tools source will have it. I checked on MSC and found that drill.

From what I have read, get the displacement of the Big Bore. I do not own a KLX so I have no experiences yet.

 

I'd put the $$ on a 351 kit. It's cheap to improve the CV carb response quite a bit. Once you've gone BBK - you won't need the pumper carb anyway.
