Grinding noise, after putting carbs back on...?

Question

OK recently i had my carbs(yes two) jetted for my pro circuit pipe, on my 2002 Raptor 660R, and i put my carbs back on today and it runs 10X better, except it seems like this introduced a new grinding type noise, is it those piston like things in the carb possibly? it sounds like its from the front end more, but it may of been that way before, but i never heard it do it previously, any ideas what the new grinding type noise would come from?

Answer 1

Need more details.

Does it happen only when the quad is moving?

At idle?

Different RPM ranges?

On acceleration?

Deceleration?

Cold or hot engine make a difference? - if so, which?

Get close to the engine to try and locate the general area of the noise.

Answer 2

carbs dont have piston things you got other problems
