MBP Collets

[Uncle Flash]

They're rated highly but I've no experience with them. Anyone here used them?

Going into my 900 Engine this week....

Decided to give them a go, they are cheap and if can offer greater time frame between shimming then well worth it I say.

[Uncle Flash]

The shimming intervals are what attracted me to these collets. They would pay for themselves in just a few months. Thirty thousand kilometres between adjustments on any motorbike sounds almost too good to be true but I haven't read anything negative about the collets anywhere.

I'm going to give them a go.

Any joy with these, Flash? Undecided as whether to buy some or not? Did you need to swap shims afterwards or did they keep the same clearances?

[Uncle Flash]

I'm the slowest rebuilder here and I've only just got around to looking at these and as I'm stripping the motor as we speak, I test fitted a pair on one valve 'just to see'. They seat the valve higher so new shims will be needed.

With the speed I'm going, it could be months before I get this lot back together.
