Update. I installed the 22g dr pulley sliders, I noticed a slight improvement in the upper mid range but nothing to write home about so I got an EPI maroon secondary spring and a set of main clutch springs. There is now a noticeable improvement in the low and mid range as well as a downshift feel when decelerating. It gives a great mid range response and keeps the motor revs up when coming out of a corner. I have another 300 that I left stock so I am able to feel the difference. The only negative is that the revs are much higher now at slow cruise and midrange.
Next mod is to remove the flame arrester, higher flow air filter, remove air box lid and rejet the xarb.
Today I pulled the spark arrester, cleaned the air filter, removed the pre filter and air box lid and I couldn't get the quad to do any more than idle, advancing the throttle or going wot would stall it which tells me it need more fuel so I'm now looking for a jet kit but in the mean time put everything back to stock and all runs good.
