Carb kits

Q: I have a 1981 Honda 750 Classic. I am having trouble finding carburetor repair kits. Are OEM kits still available? All of the dealers here in Ohio have closed. Any help would be appreciated.

A: You might try Matt Wiley at Moto-Vintage.net, as they sell K&L carburetor parts. Sirius Consolidated Inc. (siriusconinc.com), also sells kits for that year.

Throttle response

Q: Hi Keith, I enjoy reading your articles in Motorcycle Classics. I just got a modern Triumph T100 and I noticed the on/off throttle response at lower speeds is very “jerky.” I read up on this and it seems this is a common problem. There is a device called a booster plug which I have installed and it seems to help. Is there a better way to improve throttle response (i.e. ECU program). Thanks.
