+3mm crankshaft worth it??

[James2132]

I Have a taotao 150cc scooter and was planning on upgrading the crankshaft to +3mm how much more proformance should I see?

[blueboy5000]

About 2% over all.

Just out of curiosity, why the crankshaft?

[James2132]

Well I'm finna put in a Taida 61mm drop n kit so might as well add a stroker crankshaft while I have the engine apart. But i should get a lot more takeoff speed right? With the + 3mm crankshaft?

[blueboy5000]

You will get more torque, not necessarily more low-end speed..

But will the tourqe gains really be noticeable? I already have the Taida 61mm cylinder, now Im Just waiting to save up my money for the $124 3mm crankshaft. I'm thinking about just installing the 61mm by itself because I can hardly wait for the crankshaft. But 150 Scooters r so slow I should really wait on the +3mm crankshaft I guess.
