I was thinking of just making my life easy and buying dial a jet but was told by several people not to do it, so my question is can anybody tell me what I should jet at ? its a 2004 yamaha blaster with the following mods
28mm carb
v force reeds
reed spacer
key adv
k & n
open lid
fmf silencer with fatty pipe
lightned flywheel .............................. thanks for the help

 

Try a 280-290 main jet, and drop the clip on the needle one position. See if that helps.
We had a similar set-up on our Blaster, and these settings worked pretty good for it.

 

i have the dynojet kit and im runnin a 360 jet

 

dynojet jets are smaller than OEM jets. You usually end up with a larger number in those.

BTW, is it a Mikuni or a Keihin?

 

We can't say what sizes unless we know what kind of carb is on it. With a mikuni it would be around the 300 some where, but with Keihin you will be in the 150 range.

BTW, the dial-a-jet still requires you to have jets that are close to perfect, usually one or two sizes smaller is what they reccommend.

 

Well, I'm afraid someone else is going to have to help you then.
I have no idea how a dynojet # compares to a Mikuni #.......

If in fact you are using a stock Blaster carb. (Mikuni)

 

i have a stock carb. teh dyno jet kit said wiht none- mild engine mods and aftermarket exhuast and no air box lid to run the 360 main jet taht they give u adn put in the needle with the clip on the 3rd spot down. thats what im doin and its runnin prtty good. when the weather gets getter im gona exparement with different jet sizes and perfect it a lil more.

 

its a 28mm cpw carb, i bought it on ebay, it says it uses all kelhin carb replacement parts, so the name on the carb says cpw ( carberator parts warehouse) it looks like they put their name on a carb....maybe you have heard of this carb ?

 

anymore ideas on where to start on the jetting ? im gonna install it all tomorrow so more infor would be nice, thanks for the help
