hi all i was wondering if anyone has seen a strocker crankshaft for a 6v z50 motor at all and where and how much

the motor im building will be a 88cctb kit with race head heavy duty clutch high colume oil pump and convert it to a 6v cdi

then im going to convert it to a 4speed and was looking for a stroker crankshaft to install while the gearbox is out

dratv has em for about 170 bucks. I've run them and they are fantastic for the money. You have to run the 4-speed stator and flywheel though.

Powroll strokes 6V cranks but it's more expensive than buying a new crank from one of the mysterious manufacturers of the pacific rim. Other than that, you probably know as many 50-related Web businesses that sell 50-70 performance parts as I do.

What's this about 6V CDI? What's your reasoning behind that, and how do you plan to accomplish it.

Jincheng 50cc 12V cdi ignition fits on 6V tap. This eliminates the points and you can run lights which deserve their name.

will this work with a tb88 kit with race head and with the cdi conversion i have already ordered

You're gonna have trouble finding a 6v height piston for a "modern" head.

They say this works, and I have one to sell:
52MM_PISTON_KIT (OLD_50_DOME) OR (NEW_70_DOME) (SHORT_ROD) (100033)

May be easier to go full 12v and notch the case for 12v Honda CDI, or use a Lifan outer rotor or an inner rotor?

what all do you have to do to the cases to use a 12v cdi? i was planning on doing this with my motor. i was alos seriously thinking about an outter rotor if i can run lights with one, but so far nobody will answer me when i ask if you can

This topic has been covered at least 5 times...go into the search and look it up. The answer is yes..and all you need to do is modify the left case halve by grinding out one of the webs. That's it...then you can install all 12v components.

This piston will work with the xr70 style, tb, and the e22 heads on a short rod crank setup like the 52mm dratv. I've done it with the E22 and xr70 personally. Use a thick head gasket if running a crazy cam though.
