First Generation Ascots > The Thumper Years: Modified To Full Customs
FT 500 modified
Chronic:
This weekend i attended a Bikeswap, and found a Mikuni Flatslide 37 mm carburator!!!
It´s one mm to small to fit perfekt, but not a big job to fit it properly...
Anyone who have thoughs about this carburator on the FT?
J6G1Z:
Are you sure that it's not a 38mm?
White Brothers used to offer a 38mm carb kit back in the day. Usually it was installed along with a larger bore & a higher performance camshaft. A 38mm might be a bit large for a stock street Ascot. A 36mm might be a better fit. I have a 38mm Mikuni flat-slide that I've been hanging onto for the future & have considered trying it on my bike. One of the things that will make the fit easier, is a 90 degree elbow at the carb end of the throttle cable. That will allow for more clearance at the top of the carb.
Here are some jetting specs from ThumperStuff for a 38mm Mikuni flat-slide that was mounted on a Yamaha SR-500.
4.0 Slide
190 Main
55 Pilot (That may be rich & could possibly respond better to a 25-30 Pilot)
389P2 Needle Jet
6FJ40 Needle
Good luck & please let us know what you find out.
