my quad had wierd compression problems since I got it, getting worse lately. Did several compression test with and without oil today to see it's only 60psi. once i touched the decompression valve lever it fired right up.
Is there a known problem with these? do the valves maybe carbon up and stick? Once it fired up I took it for a 10 miunute spin down the street and did 45 mph for an italian tuneup. Once I shut it off the plug was black so I adjusted it a bit, ran great, then never started again... The pullcord is super easy to pull. My 300 feels like it'll rip my arm off if I dont get it the first try
I dont know how it works but I think it may have a broken spring that would keep it closed for normal operation.
