tianfeng Carburetor Fits HONDA CT 70 90 Trail Bike 90 K2 K3 K4(1970-1977)

except the drain tube hitting the case it worked great i just snapped off the tube

Looks like great quality but did not fit, the bottom float bowl drain port would not allow carb to be mounted, throttle cable did not fit this carb either.

As others have said, the overflow is in the wrong place, but the rest of it is a good fit. I wish someone would have pointed out on a review or a forum that you can tell which carburetor you need for your ct90 by the intake hole size. I ordered another carb which said it fit my '77 and it was clearly different. The intake hole was much larger. Maybe another indicator is if you have the altitude adjustment, then this one will work for you. Overall no issues. Bolted it up and it started on the 3 kick after the gas started to flow. I really didnt even need to change the idle. Rode 10 miles and throttle response was fine and the Idle was good. Only slightly more than a carb rebuild kit and very worth it.

As mentioned, the overflow is in the wrong place and almost in the way. I pulled out the brass overflow, cut it about 3mm shorter and put it back in and attached the overflow drain hose in about 5 minutes. Installed it and it started on 2nd kick and needed little to no adjustment and we were down the road. I just bought a second one for my other CT-90. I will still go ahead and rebuild the originals to have if/when these get mucked up and/or when I go to sell the bikes so the new owner has the originals but its pretty handy to have an inexpensive carb laying around that you can change out in about five minutes instead of trying to clean a dirty one.

I have 2 1974 ct-90's and after 10+ years of wrestling with the carbs I went this direction. Runs good but just dies at idle, idles fine for 10 sec then dies and takes a push start to get it going again. I was willing to overlook the need to trim the overflow and the choke on the top (hits the shroud) but going to toss it.The other bike I ordered a 110 carb and had to buy the larger intake boot for $35 but it always starts first kick and runs great. I wouldn't buy this one...

This carburetor was the exact same model that I was replacing on my CT70 with a Lifan 110 engine. With the adapter elbow already in place off the engine, it was a quick 10 minute swap. Once buttoned up, it started on the first attempt.This carb does not come with any of the extras that many less expensive ones come with (air filter, gaskets, fuel filters); it is just the carb. The problem with the less expensive ones is that there is only one fuel line inlet and you must install the in-line fuel filter. With this carb there are the two fuel inlets, primary and reserve, that come off the typical CT70 fuel tank. Also, the fuel filter is build into the carb, so no need to cut a line to put a filter in. I will be buying another one for my other CT70.

This carburetor works on a CT90 K1 and K2 however the lever that operates the Choke is pinned on upside down and doesn't allow you to choke the bike because the lever runs into the cover mounted over the frame. You can modify the choke lever by cutting it down so it fits under the plastic molding but it does make it harder to find and operate.

Fits a 71' honda ct90 trail. Had to modify the drain as it wouldn't clear the engine. Other than that works perfect.
