David Good to hear the TY had a win. I used the strobe connedted to the car battery and found the timing to be about 25mm from TDC and altered it 22 mm. I did not notice the differenceto tell you the truth. Will stick with this for a while. But now will use the strobe to check the timing. The cam fo...

David I will give the dynamic timing a go tomorrow. I previously made some timing marks in the flywheel and case and standard timing looks about another 6mm BTDC than your 22mm. My points gap is on the low side. Points seem OK so I believe it must be a worn cam to have this effect? It will be intere...

Rob I have been mucking around wit some Koni shocks and adjusting shims and drilling holes in pistons etc. I have examined a friends pair of new Ikon shocks with the spring off and damping is very slight.
