OEM crank size

[Rockyp]

I'm searching around for the OEM crank size for a 99 GSX. I've read some saying 88 and others saying 100. I'm not sure which one to order. Any help would be appreciated.

The stroke is 88mm.

It's 88mm, you can also use 1g 7 bolt cranks and Evo cranks.

For future reference, the 100mm cranks are for striker engines.

4g64 crank is 100mm stroke, 4g63 crank is 88mm reguardless of bolt number (6 or 7).

And stroker engines are, 4g64 crank in 4g63 block (2.3)L stroker. Or 4g63 crank in a 4g64 block destroked (2.1)L
