bottom ends

6 posts in this topic

im just looking for some info

im building a hybrid quad and im looking for a engine to buy or build

does anyone know if any yz fourstroke bottom ends are compatible with others?

i know yz's/and wr's are pretty close, but what about other engines

a list of what works would be a big help

can a yz400 bottom end mate with a wr400/yz426/yz450 top end?

if it uses the yz400 crank?

Don't use a YZ450 crank if you plan on having the electric start.

Gray, just curious, can you pls explain why :D

The left crank axle is different on the WR to accommodate the larger flywheel and the starter drive mechanism.
