Re: Help needed on '49 500VH rebuild

The top of your valve plus cap must be 4.5mm higher than 90 degrees to rocker ax center, how ever you do it.

The springs are related to the intended rev's.

Re: Noise

Some rockers have rings in stead of springs, if the oil banjo's are titened to much at one point the rockers will turn heavely giving the same problems as you have.

Re: 1949 ariel 350 twinport

There are plenty 350 engines, but a 500-600 gearbox and oil tank are difficult to find, so that will belong to the frame.
