HERE IS WHAT OUR VERY GOOD CUSTOMER VERN SAYS ABOUT THIS CARB SET.

Hi Jack & Claudia Yes, the carb,and the CT110 boot are a good replacement for the stock 1977 CT90 carb and boot. No adapting.

I replaced the main jet with a 66 and it runs fine. I haven't checked the spark plug to see if it is running rich but it doesn't misfire, sputter or bog down at high speed (45-50 mph)

The carb's overall length was shorter than the stock carb by about 3/4 of an inch. Whereas the CT110 boot was longer than the CT90 boot by the same amount, 3/4 of an inch. The combination of this carb and the CT110 boot resulted in the same overall length as the stock carb and boot.

The intake opening of this carb is larger than the 1977 CT90 stock carb and the CT110 boot has a larger opening than the CT90 boot, so it was a perfect seal. I did have to use a larger hose clamp because of the new diameter.

Even the cable and end cap fit into the slide without any adapting.

Thanks for stocking & providing such hard to find items and useful information. My CT90 hasn't run this good in years!

Thanks for a great site!

Thanks again Vern
