Scott's Solo 681

[Deets066]

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.

I've got a 7910 jug and piston, but I just can't bring myself to take the 65 cc jug off the one I've got.
Besides I still have a smurf to build

The 681 was the last latest, biggest 6 series Solo made.....I dunno if I could put a 7900 jug on one. A 665 maybe, but what 65cc P/C runs as good as a 665 does...tough one. Scotts saw runs nice.

It's not like Wow.....what a huge difference!!!! Besides......your 665 is dialed in. Please don't tamper with it.

I'll try to have a 665/7910 hybrid for you to run too.
