Picked up a brand new blaster recently. Broke it in some but as I push it harder it won't rev., just sputters and goes flat past 1/3 throttle. Took the air box lid off and it runs like a raped ape. Mechanically everything seems to be OK. Anyone else get a new blaster that runs extremely rich? BTW at sea level and about 60 deg.

 

I've never heard of a need for a jetting change after break-in on any model.

You sure the air filter just doesn't need cleaning?? Did you change fuels or injection oil?? Did you change to pre-mix??

If it isn't the air filter, take it back in to your dealer. Even if it does require jetting, warranty will cover it and all the trial error required to do so.

 

lean is fast but can be BAD your realy hurtin the thing. put the lid on and go down 2 sizes and check it and from ther go down 1 size at a time till you get jeted right

 

and you could try dropin the neddle a clip move clip up to lower the neddle. pilot jet close to 1/4 neddle is 1/4 to 3/4 main 3/4 to full .
