Alsport Trisport

[Troyleedee]

Picked up a trike and had a few questions on the motor and possibly year of the bike, i was told it's an old snowmobile engine rotax 650, not sure if its 2 or 4 stroke and the carb is wrecked, plan on cleaning it up and taking it out to the desert, any information would be much appreciated, Thanks!

Nice Alsport.

I hope to clean it up and buff the fiberglass and all the chrome, pretty pumped it came with vintage Fox air shocks, Fox quoted 83$ a piece to rebuild

Those shocks aren't original. It came with a set of coil overs. Maybe two, if the option was chosen. http://rover.ebay.com/rover/1/711-5...0001&campid=5335845805&icep_item=264715496798

Those trikes came with Showa shocks.

Pretty sure that black paint on the body isn't suppose to be there. EZ off oven cleaner would probably wipe that right off.

A guy on ebay has some NOS factory Showa rear shocks for the trisport for 100$ a set, or should I keep the Fox air shocks?

That rotax is probably why the rear frame was cut. With a 650 power the diff may not last long

The air shocks could be a nice improvement, over the originals. But, if you don't intend to carry excessive weight, there really is no need for them. Showa is a long standing, high end product maker. Their shocks are, or have been used on almost every motorcycle ever made. With the adjustability, built into the Showas, ride comfort and height should not be an issue.

I dont think the rear frame has been cut

That raised section above the shock crossbar shouldn't be there. The crossbar should be just straight across. Solid from shock to shock. On many snowmobile engines the carb will run right into that bar. I did similar to mine to mount a mikuni on the kohler.

and the fox airshocks are from around 1978?? popular or off dirt bikes back then and they were very pricey!!for the day they are worth something now

What I meant is that it should look like this. The center has been cut and an upper brace was added. These, including maybe yours, came with snowmobile engines. The carbs normal position put it right inline with the bar.
