Thanks for that,,
My 485 is in an rz 350 street bike,,,with electronic servo power valves,,,,,,i am aware of the problems with the "trinity" domes,,,but i have to say i have no problems with mine (27cc 10 degrees and about .50 squish.
I did specify what i wanted,,and that it was going in a street bike,,,,,Harry looked after me,,,,,i have done 8000kms in nearly 3 years and it hasnt missed a beat.
I have a zeeltronic fully programable ignition and pv controler,,,,and a map switch on the bars with 2 curves.
Despite a lot of shit on the net about these motors,,,WHEN built right,,,they simply RIP. and 100hp is easy to crack.
