'89 model with end can (legal, removeable baffle which will stay in) and maybe a replacement HRC type foam airfilter element. Otherwise stock.

Any ideas on main jet sizes to start with? Is it worth changing the jets at all for just the can? (read somewhere the early ones are a tad lean to begin with...)

Cheers in advance.

Stick with a standard filter and go for 118 120..

Am sure there is a search function on here

ok thanks
