Bridgestone 90
- Thread starter oldjeep
- Start date
I've done a long line of 2 stroke snowmobiles, but never one with a rotary carb.I have never worked on a two stroke until recently. Joe has a RD350 that we are tearing down the motor for Paul to do a full rebuild. Alien tech in there don't you know.
Toss this in the office now until I decide what level rebuild this is. Pretty sure that it will be a - leave all the patina and just get it moving build. There is one source of parts, they are not cheap, and the bikes are worth little when done.
I guess that I will need to paint it. The upper triple had been welded poorly (couldn't see it under all the gunk), the painted portions of the fork tube were bent and dented in more directions than I really care to fix. Bought a good used complete fork, but it is red. Since the paint code is unobtanium for the bike, trying to decide if I should go for a similiar metallic blue or just paint it up like the CA95 (Rustoleum safety blue)
Too bad they don’t make spray on Bondo that is self sanding. Someone did the “Mop and Glow“ on the CL160 and just painted over everything, rust, dents etc.
Sometimes pride of workmanship touts the dollar value of the end result.

Yeah, I really don't want to have to do it. This was just going to be a make it run kind of build. If you could actually find touchup, it would be no big deal. I'll likely just sand and primer the 2 fork tops and then decide later when this one runs. Takes about 20 minutes to take it apart, so no big deal deciding later.Oldjeep says above ”I guess I’ll have to paint it ..”…sigh !!! Mission creep occurring already and only on post#6 !!!
Yeah, I have done that for old cars back when I used to build LBCs. Unfortunately these days with all the environmentally friendly ingredients it is hard to get a real match, especially on a metallic color like this one.

I really, really suggest that you look at the hobby paint brand "Testors" found at Hobby Lobby or an RC shop for that metallic blue color or a close match.
The 62 rear fender needed repair, and I just needed a close matching color to the old original paint. Testors red and clear coated with the same brand. See pic. Also back in 2017 I was able to match the deep metallic red on my VT700 plastic side covers with Testors paint. Here is a shot of the 62 rear fender during the build. Not recommended for fuel tanks though.

Definitely worth a shot. The only thing on the BS forum (which I can read but not join) is that GM metallic blue is sorta close, but not very close.
I have matched many metallic's very close. Its worth a shot, if you have a vendor close by you maybe surprised. I blended a 1981 Goldwing top shelter with what was a GM colour with metallic. It was flawless to the normal observer. I was amazed myself how close it really was to the original colour.
Like I said, actually been there and done that - for like 30 years
Even the old school paint shop downtown was hit or miss in terms of actual color matching. The only real way to do this is with multiple spray outs and a paint guy - and that exceeds the budget of a bike like this.Been out of the country for a couple of weeks - was supposed to be one, but our illustrious leader caused some issue in the southern Caribbean that necessitated a longer stay. 35th anniversary trip, so not complaining about more than what the extra week cost us.
Mainly just trying to assemble what I have, next is to get the wiring harness sorted out. It was cut up a lot but I think that the diagrams I have will make it pretty easy to reconstruct.

Major congrats on the 35th anniversary, happy for you both.

Over fifty years ago a Bridgestone 90 was the first motorcycle I ever rode.
It was a great summer.

One of My friends had the trail bike version, of that 90, only one I ever saw that had a rotary shift pattern.
Yeah, it is weird. this one is also a "Trail", although it seems to have the "Mountain" double rear sprocket setup.

The "Trail" came with a dual sprocket setup as did the "Mountain". However the "Mountain" had an upswept pipe, short seat and more robust luggage rack. I also have a "Trail" version.
Started work on this one again since it is the last project in the garage. The FZ750 sold early this spring and the MZ Skorpion left a couple of days ago. Unfortunately had to yank the engine since it has been leaking all over the table I was storing the bike on since I first added oil. Seems like there is a gasket issue near the rear of the case - which means that I have to split the case. This is one of those - never should have started it projects due to cost of parts and eventual worth. But since we have gone down the road this far, will put this one in the loss column eventually and let the FZ750 and MZ suck up the loss.

Looking forward to seeing it road ready.
Never been a fan of vertically split crankcases, PITA to reassemble.
