Quick check…I’ve just set mine to 0.10 mm in 0.15 out. Is that right? Please say yes!
Yes! And not just because you want to hear it
Cheers Mate! I was asking because they were so tight when I first checked I thought I might have misread the specs. Suppose I’ll have to put up with a bit more clatter now they’re properly gapped
It is said I believe that you can make them wider, they’re only that small in the first place because of namby-pamby American(?) regulations, about engine noise I think. Me, I’d want to be sure the valves stay properly shut and gas tight if as and when the motor gets good and hot and everything expands. Just IMHO. There was a recommendation, can’t remember, an extra 0.1mm? HTH
I think 0.1 would be a normal safe margin for error based on my own skill at setting gaps correctly. I’ve just read somewhere else suggesting the range is 0.10 -0.15 in. and 0.15-0.20 out. Sounds like a wider range than normal to me, and I suspect the clatter could drown out the very pleasant but robust sound of my Mistrals if I went for the wider of these settings. All humble opinions gratefully received!
If you’re doing them in inches I would opt for 4 thou inlet and 6 thou exhaust. Works on my 750 Breva and yes don’t those Mistrals sound great especially around 5 to 6 thousand rpm.
As this is a metric bike based forum I tried to save electrons by not putting mm after each figure. Suitably chastened I shall not omit to do so in future
Love my Mistrals!
Noisy is generally better than too quiet. (Tappets I mean)

I was told 15 and 20 max. A bit noisier but safer.And as the Pfatzfeld crew could tell you she buzzes along OK.On the subject of increasing power(that is why you fit Mistrals isn’t it) I have just fitted a K+N air filter.
Dunno about any power increase but Moses could have used them as a backup as they’re excellent when it comes to parting the way through traffic.
