El capitan Posted August 21, 2010 Report Share Posted August 21, 2010 decide to address the carb mani gaskets which were leaking, and finally use the rebuild kit i bought forever and a day ago. tore it all apart and found that both diaphragms had holes in em'. one had a tiny pinhole... the other.... pinched and a nice slit in it. fuck me.

ReconRat Posted August 21, 2010 Report Share Posted August 21, 2010 I've had a few of those. It seems to be a weak part of the design. The vacuum diaphragms just won't last forever. I prefer simple throttle slides like Mikunis have. I remember gluing one shut with RTV, but I wouldn't recommend doing that. It would have to be fixed again soon. The bad part for me was when I went to buy a throttle slide/diaphragm, they said I had to buy an entire carburetor. I refused. That was overseas in Japan and the carb cost near as much as the used motorcycle. Or it seemed that way at the time. Quote Link to comment Share on other sites More sharing options...

El capitan Posted August 21, 2010 Author Report Share Posted August 21, 2010 Scored a set of used diaphragms on eBay for 70 bucks shipped. Better than 99.95 a piece without shipping for the new ones. And I'll get them next week instead of 3 weeks or so. Quote Link to comment Share on other sites More sharing options...

ReconRat Posted August 28, 2010 Report Share Posted August 28, 2010 After fiddling with carbs, check for air leaks between carbs and engine. That would cause a rough or low idle. No problem at higher RPMs. Spraying water around the joints will seal them temporarily and the idle will go up or smooth out. Quote Link to comment Share on other sites More sharing options...
El capitan Posted August 28, 2010 Author Report Share Posted August 28, 2010 It idles good, no leaks at the manifolds either. I'm going to check the hats that cover the diaphragms tomorrow. It ran real strong today, and I think my mileage has improved by quite a bit. I never knew how bad it was til I saw how good it has become. The throttle response is really quick and snappy. And my exhaust has a nice crisp bark to it. Quote Link to comment Share on other sites More sharing options...
