Re: 2001 800 RMK goes pop!
the 2001 800 rmk head when installed on my ported and piped 00 800 rmk netted 165psi of cranking compression. This is way out of limits for most peoples finances (you have to run 114 or better gas) If you have the 01 800 and ride art sea level, you can get the 00 800 head and top cooling hose for about 160.00 us. I bought the 01 head for mine for 103.00 prior to buying dial a domes to cut compression back to 145 and offer some flexibility in the fuel dept. Putting last years head on the 01 will still produce at least 128.9 h.p. because mine did over 4 consecutive runs on the dyno last year. This will also solve the burn down and holeing of pistons. remember that the needles are leaner on the 01 and the jetting will also be different. later
