Re: Does anyone else own a Honda NS 50?

In 1990, at the advanced age of 39, I bought a new Honda NS 50 with the intent of going racing. I had been eying mini racing, but I didn't want to go with a Yamaha YSR 50, mostly because I didn't fit(6'0" and a svelte 170# at the time), but also I didn't think much of it's antiquated under-squa...

Re: A little 2-smoke humor

Oh, and I see you have a Gyro. I'm not sure which model is the S, but I remember riding one once, and forgetting to lock the steering colum as I stepped off. It sort of toppled over in slow motion like the tricycle on Laugh-In:) To see a good picture of a Gyro, look in the dictionary under "und...

Re: A little 2-smoke humor

The Dealers were supposed to paint a large red dot on the underside of all Iowa Spree seats, but not all did. I think Honda made way too many of them because they could be had for $299 and I even saw a few that went for $199. As far as I know, the only different between the Iowa Spree and the 49 Sta...

Re: broken cooling fin (updated with pix)

What is that, a MB5 cyl.?
It can be run as is, the engineers design plenty of cooling area into an air-cooled cyl.
It could also be welding without any warpage issuses, but it's not necessary.

Re: crank threads

I used to press the mains on the crank and "suck" the case halves together using extra long case bolts.
Going to shorter ones as the two halves come together, obviously.

Re: Question for a guy who knows nothing.

Doing a compression test on something like a Spree is somewhat tricky. The swept volume of the cyl. is so little, in comparison to the volume of the gauge/hose/adaptor, that usually the readings are on the low side. Suffice to say, with one's thumb over the spark plug hole and cranking w/ the thrott...

Early Honda 50cc mini racing.

Re: The Scooter Doctor says hi.

From another post; <<<<Aero 80, probably the most reliable scooter ever made, period. When I had my shop, I saw 10,000, 20,000 mile and more units. The crank and brg.s are robust and the top end is near seize-proof. The exh. port and pipe are big enough to not get clogged-up with 7-eleven 2stk. oil(...

A little 2-smoke humor

Wildfire and the Runaway Spree. (or taking it to the wall) ..It was an honest and fair shop, consequently when spring rolled around, a busy shop. Some bikes had to be turned away. That was one of the unfortunate aspects of being a service writer. The kid, still panting from pushing his rather beat a...

Re: The Scooter Doctor says hi.

Well, I don't actually work on scooters any more, except my 70cc Eton Beamer, couldn't afford it! In 2000, after 25 years as a Japanese Motorcycle tech, I switched over to heavy equipment mechanic. The pay for M.C. techs became less and less over the years and the dealerships are just businesses(not...

The Scooter Doctor says hi.

Hi, I owned and operated a Independent Scooter shop from 1984 to 1991. It was situated near a large university in the South West. I had been a tech in a large, impersonal Honda dealership, which after they sold them, didn't want anything to do with them. I was a good opportunity to strike out on my ...
