Wondering if by dropping my needle jet clip it would reduce the hard carbon build up on my plugs?[99 600 mxz]checked the compression and it's even 140psi.Fouled my first plug but have noticed that it runs a black colour since i've owned it.I ride the trails at a moderate speed 1/4 to3/4 throttle so the main jet wouldn't come into play a whole lot.What are the stock main jets for this machine? I haven't checked because I have it serviced each winter.I ride at about 1000ft. and rarely see it colder then -15c
