hi, did it today . took off 4 parts - seat,trunk,front cover and valve cover. both valves a ok . warmed up engine and changed oil and filter, used 10-40 mobil 1 oil. no i didnt even check that oil strainer ,what for ? now its wide open time maybe i'll try that 9000 rpm, at my weight i'll need a slight downhill helper. i also installed a small windshield , got a 18 x 24 sheet of lexan. took off joke shield and made my own. could of made it a little larger but it keeps wind off the body and deflects wind over my head . lexan cost 18.80 at lowe's,not very thick maybe 1/8 in ,but it seems ok.
