Replaced the stock carburetor flange with one for a Yamaha RD street bike (part #345-13565-70-00) from HVC Cycle. The RD flange is supposed to be better because the opening is centered and therefore not partially blocked by the reed cage. The carburetor is now closer to the exhaust, but there still seems to be plenty of clearance.
Cool. So all you had to do was sand away those wings? Any other fitment issues?
Also, what reeds did you use?
Thanks,

Getting rid of the wings is all that’s necessary. The only fitment issue I ran into was when I tried to replace the OEM carb with an OKO carb. The OKO is slightly taller and the carb opening on the RD flange angled a few degrees less than the stock TY flange. This causes the OKO hit the top of the crankcase. The OEM carb fits fine and I think some people just ignore the contact between carb and crankcase with an OKO. Originally I used the stock reeds, but recently switched to a set of Boyesen “trials” reeds. I think they made a bit mid-throttle improvement, nothing dramatic.
Thank you for the clarification. John over at TYtrials in the U.K. offers another brand of reeds made in Florida for Banshees mods. I might consider those.
Did you find and improvements in performance using the new intake manifold? Recommend it?
Thanks!!
Patrick
Sorry, I didn’t do before and after rides to see if I could tell a difference. The intake was changed as part of rebuilding the engine. I should do an A/B test sometime.
Hi my name is Clyde,I’m looking for a exhaust outlet for the muffler on a stock 1976TY175 do you still have yours
Sorry, I don’t have one for sale. I’m going to hang on to the OEM one in case I decide to put the bike to original condition. It’s pretty beat up anyway. They come up for sale from time to time on ebay. There are a couple listed now.
I think a ty250 silencer is close to the same as a ty175. The aftermarket one I purchased is supposed to fit either a ty175 or ty250.
