YUNGGUNNAZ:
top is the 89 off ebay.2nd. is a 99 and 3rd is off another 89. on the pic with all three left is 99,center is 89 off ebay and right is a 89.notice angle at the top of intake(roof) on the right cylinder compared to others.this one has exceptional mid and top end.not from this alone mind you.

Younggunnaz,

If you have a outbored <88mm ironsleve,you know you can use a Ho..a piston! :wink:
89mm and further up to 92mm I think.But you have to make a spacer underneath to raise
barell to suite porttimings. :evil:

About barell -89 with some "strange" inlet-roof ,I?m blind proberly,but unlight me plz again! :?

YUNGGUNNAZ:
bottom right cylinder looking just above intake port.this section is slightly angled down to aid booster(auxillary) ports when using the spacer.also the booster ports are angled different from 99 cylinder hoping for a swirl affect somewhat.i'm still a rookie with ideas to trybut been fooling around with these things since f7 rotary valve days.just having fun.have a 90mm  piston and gasket on the way.right about the red bike piston.might try that this year on one of them if this don't get er done.also once a few races are gone plan to plate this liner.
