Yoshi Kits
« on: April 17, 2012, 05:00:54 PM »
Yoshi 812 kits - are they any good?
Will one for an F1 fit an F2?

Thinking about getting a spare F2 head and doing some performance mods - the F2 already is designed to rev higher than the rest of the range hence the stronger springs and different valves - are there any other changes that would make a good bit of difference?

Would it be worth upgrading clutch, cam and chains etc and are there any suitable upgrades available?

I have ordered Hondaman's book but it says it's mostly for the K range so I don't know how much help it will be with the F2

Any advice appreciated

Robbo, make sure you get the right pistons for the F2 as it runs a higher compression

Not the compression thats the problem it's the chamber size in the head is different (bigger) so F2 head with F1 pistons = LOW compression; F1 head with F2 pistons = BANG
