ISO Yoshi ST-1 & ST-2 Specs

[nightrider]

Hoping to finally work on my slabby this winter.

I have a set of Yoshi ST-1 and ST-2 cams but don't have the set up specs for them.

Anyone have a scan of / or can quote me the specs from the set up sheets please

(most likely going to put in the ST-1's. Don't think I will have the time to put in shortened valve guides and all)

Perfect Jaydee, just what I needed

ST-2 Specs are more for the future, ST-1's are going in this winter for sure.

Doing a bit of head work. +1.5mm intake and cleaning up the ports plus a tad more cc's. ST-1's cuz I got em.

Easy stuff this year. Big stuff next year
