Speed/Ninja crank
I have a Speed and what they said about the speed crank with tung weights is correct, it also has the black coating, not sure how to tell about the timing. Our speed motor is great, it is blaistic, off on power, thats why we tried the ninja, it has smooth power, but inconsistent tuning. I ended up puting our backup V-Spec in just before the main,its been in the box for 3 months, I just leaned it out 1 hr on top after the warm up, and after the main it came off at 230, OS solid consistent motor, but I'mstill gonna try just swapping the cranks and I'll let you guys know how it does

Massivmods, i think maybe you think of the old GRP ninja? The OS Ninja is same bore/stroke as the V-spec/speed.
I got some info that the Nonja enigne has bigger crankcase volume than the V-spec and this is why you get more power from the V-spec case.
The ninja crank has araound 210-214 degrees of duration while the v-spec is araund 220-223. In theory, the V-spec crank will have more outright power, if you compare timingwise, but thre is alot! of other factors in witch crank is the easyer one to drive and gives you the best laptimes.

Well the v-spec does have a different powerband than the ninja. I wouldn't say either one is more powerful, but they are different. The v-spec has slightly more bottom end from my experience with both engines. That can be attributed to it's 3 port sleeve vs. the 5 port sleeve of the ninja.

when the rod went I replaced it with a stock vpec rod and drilled a oil hole. I was wondering if I could use a speed rod as it is predilled.

so, what rod is in a promod vspec? it has a speed crank with vspec sleeve. It is not a vspec rod. it has knife edges and an oil hole.

fyi, i did a search on google earlier for the heck of it looking for certain parts and found vspec cranks NIB for 50$ and less. I actually found one for 35$ brand new.
I know they have garbage crank pins, but for that price it does not even matter. Even if you only get three gallons, you could get a new rod and crank for 70$ pinch the sleeve and put in some tko's.
120$ and you have a new motor
