Greetings,
Just found the forum. Longtime Honda guy with very little ATC/TRX experience.
Trying to build a 4 speed motor that has a 4 up shift pattern

I’m using an OEM Honda 50/70 Horizontal engine (Z-50, CRF-50, QA-50, CT-70, Sl/XL70 or ATC/TRX70………)

Can someone help me identify or find the right models and years of ATC and TRX 70 with a 4 up shift pattern?

Thanks!

Mike
