well got the cylinder bored to 44mm for 42 mm witch is already bigger than the stock 40mm :) and i have 42mm crank not the 39.5 stock one .
So fitted the piston and cylinder.. the head was cut out to 44mm also
modified the clutch to 3 plate .
well on the way now lads .
so all wired up other than the tail light .. got SPARK.. that’s a big deal :)
I think with in 7 days i will fire it up ..
I did a mild port job after these pics . lifted the exhaust port 2mm and opened and raised the boat ports at the back 5mm
then knife edge the bottom to match crank case
