I've came across this before in a few other posts. I had a blast today riding but the dust killed me, I swallowed a good pound of it lol. The parts of my face not covered by goggles or helmet were a nasty combination of two-stroke smoke and dust lol, you gotta love it. Anyway I better clean the filter after that and put the stock one bike in in the mean time. Usually I used gasoline put I don't have much (other than the premium for my bike lol) but I do have mineral spirits and from what I've heard, it does the job. I'll probably get to it tomorrow so I'd appreciate a reply. Thanks again.
