Scott's Solo 681

[Mastermind]

I've been in this saw a few times. It first showed up already ported.......I tried to save it with a 272XP piston. It turned out sorta ok. Then Scott supplied a new 681 top end.......and it was better, but there was more to be had.

So.......I went back in it yet again. Just a few small changes.

Nothing wrong with that.

Them 681 top ends are rare and pricey little buggers.

And I think the 7910 top end on the 681 turns out a little better.

Yep......

And I've had it for several years. Seems to be a good bar.

What do you like better about the 7910 jug. I thought the 681 jug was the mystical unicorn everyone was lookin for?

The numbers work out better after cutting the squish to allow for the stroke difference. The longer stroke of the Solo means not only does the piston move further up the bore, it also travels further down. So, intake height lands in a better place. The 7910 top end has a huge exhaust outlet.......and a better piston.

Looks real good Moobs.

Don’t know a thing about dem solo’s. But I know what runs good, and that saw certainly does.
