ninja parts in a v-spec ??
Someone told me i could put jx .21 parts in my v-spec. It needs a piston & sleeve . Do i have to replace the crank also. I would think i would have to. Anyone have experience with this . Thanks in advance.

If you use a speed or JX crank, you will need to use either the JX or Speed rod. The reason is the oil hole is different in the cranks of the jx/speed and the standard vspec. Other than that, you should be able to drop in the jx sleeve and piston right in. Be sure to check the rod though. It may be a good idea to change the rod just in case the bushings are worn. Good luck.

Sorry i didn't say but i am replacing the rod as well (with a speed rod or ninja rod) as the bearings, seals etc. I am doing a complete rebuild. I could get a repinch but thought i'd just rebuild & see how it goes.
go for it

We tryed this and the v-spec has a differen timing than the speed and jx.
you can put a jx sleeve in a speed and vice versa but it you put the ninja sleeve in the v-spec it wont tune up properly, you'll have to put the crank in aswell. and if your going to all that trouble you might as well just leave it all in the ninja

I've seen a hybrid motor which of speed/jx parts run. The motor I saw was a fellow racer who had cracked his speed case, and was just fooling around. The motor he had built was just plain wicked! It was impressive enough for me to order the parts to build one just like it. I run speed motors and have to say that his motor had the bottom like a speed, but would just keep reving.
