The stock drive train will handle that there is no way its 3 times more powerful than a HY 30.5. I would spend my money on upgrading to a 4 bolt Zenoah though you will be a lot happier IMO.

Why did you title the thread Rovan Motor? It looks like OBR to me. ;)

OBR has some great motors.
 
some where round here is a kdx 220 shop manual---- here it is! -- lets see-- units of power: KW - x - 1.341 = HP. Units of torque. KG-M - x -7.233 = FT-LB. according to my abacus-lol- the venrable hy 30.5 produces 1.47 hp @ 12,000 rpm.- I really think the factory should have me over there for the dyno run-- I would have leaned the carb out a bit-lol! yea, 1.25 ft lbs of torque @ 12,000. - damm, i wish the kdx would have been 20 pounds lighter--- would have kept it---
 
well-- the abacus broke. soo- back to the texas instruments calc. - 3.8 kw x 1.341 = 5.0958. five horses.- thorbreds i assume-- this has gotta be the obr---
 
looking at doing the same with my dunerunner,looking for an upgrade for an engine. ive talked a little bit with the guys at daves discount motors,and still looking for more input as to more power as well as speed,ive seen alot of different things posted....soooo...any help would be greatly apreciated
