Well I WASN'T into scoots.

Now this whole evening is shot. Thanks. I especially like the "RG 500 4 CYL Wide Body..."

Latest "Scooter" magazine (here in Oz) has a V4 2-stroke made by a Spanish company using 4 race barrels from the Minarelli stuff.
V4, 350cc, 110kW (I think, around there anyway).......in a Gilera Runner size scoot.
Hehehe!

I need to take some dimensions under the sheet metal although I'm thinking a liquid cooled single or twin might be my best bet after all for this project. I feel I can hook up a shifting linkage to mate up with original floor board shifting hardware. Any ideas on what engine would be the most compact in size? I'm not really sure what has been produced in L/C form in 250-400CC 4 stroke over the last 20 years or so. I have a couple ideas on locating radiator without cutting any sheet metal. 12 volt lights,etc will be a nice upgrade too.

That's a classic, for sure. Love those old '50s scoots.

Engine-wise, with gears, my personal opinion (valued highly by my children, as you can imagine.......):

LC singles and geared - WR250R/X. Good power, reliable, light, LONG service interval.

AC singles and geared - TTR250, XL250, SR400.

If you're going for a true "twist-n-go" auto single, it's really hard to go past the Piaggio Quasar drivetrain, very smooth and understressed, huge aftermarket, but the Kymco 250cc G3 drivetrains are slightly rougher in operation although they have excellent reliability and performance.

Having said all that, a Ninja twin would be cool.

This B&S has been warmed over and puts out 25 or so hp now. The bike will go over 80 mph if, you are brave enough.

This is very interesting to me. I am currently building a 1975 RT-1 Rokon and will use an 18hp Briggs & Stratton for the power. My engine will arrive soon. Any tips?
