3000 rpm? What rpm do you start your dyno run at?

ok..that's about the same rpm we start our pull's too..it's making good power,any track times yet?i have a buddy w/a 06 w/same power as ur's and he was curious of what they should run.

Sorry it me so long to respond its a WR 450 crank 97mm bore, 14:1 cp piston, 45mm HSR Carb, and running VP M5 fuel, I ported my own cylinder head stock valves and springs, web 923 cams. No stroker in this one but my new 501 will be a stroker 98mm bore.

2004 DS 770

red 05 plastics

red 05 seat

stock stearing stem

stock handle bars

ODP A-arms

custom +7 swing arm

not quite 3 quarts of oil

a little bit of oklahoma sand, and Genoa sand, and Off Road Ranch sand/dirt

ron wood front 16t sprocket

sprocket specialist 40t rear sprocket

530 chain lubed with wal mart chain lube



71 horsies

61 ft lbs



But thats only because it was like 100% humidity, and like 140 degrees outside, and dyno shop had no ventilation, and the dyno tires were like 100 lbs each, and it was slipping the tires on the drum, and slipping the clutch, and the timing was extremely retarded, and the only fuel we had for it was like 180 octane. So with all that considered, it normally would have been like 97 hp and 75 ft lbs, easily.

if you went to mrx01 or mr12 youd see more hp and more overrev.
I have thought of trying MRX01. I have a different exhaust cam on the way that has 4 more degree's duration .020" more lift. That and some degree changes should bring up the rpm at which it makes peak HP. Still need a good Dasa drag pipe to finish it.
