Hi,

Nice bike, but why do you want more power?

More power = less reliability and the parts for the 660 engines will be harder to get and probably more expensive. The parts for the racing 660's are incredibly expensive.

I got my standard 640 engine rebuilt and balanced by Swampy when it was new so it was as smooth, economical and as powerful - with the standard carb - as possible.

That electric starter may just save your butt someday. It'll come in handy, if you have to have both feet firmly planted on the ground.

This is an exercise in wasted time.

You won't gain enough power to make the expense and hassle worthwhile,
and you will lose reliability.

There is no need for more power except when on paved roads, because the power the stock bike has is sufficient for any off road conditions.

Bottom line : if you want more power, you should buy a 950 Super Enduro. But unless you have superhuman strength and world-class riding ability you can forget about doing any serious off road with that bike.
