This would be good. I'd almost come to the conclusion I was going to do this anyway because it's all very marginal at best. I may even need to file a slight flat on the spindle "rim" at the 12 o' clock position. Whatever else is going on, this won't do any harm and is most easily done with the spindle off the bike.Haggis wrote: ↑Wed Jan 12, 2022 3:45 pmIs this not the case with high lift cams.
They were re ground to reduce the base circle which gives a similar effect as a high lift cam.
This makes the cam smaller, just like yours.
The fix was to machine a bit of the case to allow the follower to move further down.
I'm going to replace the spindle anyway because it wasn't like this when I built the engine and also the spindle has rotated on its seat, which shouldn't have happened.
They list the extractors but they are out of stock. I may have found one elsewhere.Adrian wrote:I don't know if our hosts can confirm this, but I gather tappets with slightly smaller diameter feet are "a thing", might be worth investigating.
Also pretty sure our hosts have screw-out extractors for cam and idle pinion spindles, slide-hammers seem a bit extreme.
I'll look into smaller head tappets next time I have the top end off. I'm hoping I can deal with this issue without pulling the motor apart.
