Stink Racing

I've slotted the cam drive so I can adjust it and set the cam and crank at the std positions. The cam drive is a degree or two further forward than normal which would be right with 1mm off the block.

Ignition timing has been changed but made no real difference. Block height has changed. I just want to set it correct. To do that it must be measured.

Slotting it both ways still doesn't tell me where it should be...

Had it out on the track today but there's still no top end.
Pulls nice and clean from the bottom of the rev range then goes flat at 50 or 65%. Revving higher it starts to miss.

I will be looking at the timing first, then the cam timing.

The motor is still in the tuning stage. Last meeting showed a slight miss in the mid range and up. At Sully's suggestion I changed the timing which helped a bit.

Since then I have fitted the lightened flywheel (woah! what a difference) and enlarged the mains a little (very little). Next weekend we shall see how she runs now.
