Question I don't have enough space to mount my carburetor between the engine and the frame

Is there any way I could extend the carburetor witha piece of pipe or anything to make it fit. The reason it does not fit is because I installed the universal U-Mount because my frame was too thick, and that raised the engine, making me unable to install the carb. I have the NTTC Carburetor from my kit.

You might be able to buy an offset intake tube.

I think I've seen people do that.

Other than that, it might be a cut turn and weld job.

Definitely post a pic... the last thing you want is to have to use an offset intake... especially if you like going fast...
Mine had clearance issues and I got mine to fit on with a shorty intake, i had to notch the air filter housing a little tho, but it all fit... barely...

One of the members here, Powertool, used a copper elbow from the plumbing section of a hardware store. Slice the end going over the intake, and secure it with a hose clamp. Or at least that's what it appears. I plan to try it myself, when I install a motor on my Roadmaster Granite Peak, which is the same make/model bike he built.

Like everyone else says post a pic!

I did something ugly to get my air filter to fit on. I don't recommend it but it still seems to filter air fine.

Yup, that's ugly... but if the filter isn't restricted sometimes that's what needs to be done...
A shorty intake would solve that problem tho if you can find one, it would put the carb about 1" closer to the cylinder and about 1" lower as well. It will move the powerband up just a little but that could be a good thing depending on how you ride.

Yeah, I don't have a short intake, I was considering grinding some off on the bench grinder to make it fit better, but, meh, it's been this way for 100s of miles.

Where there's a will. there's a way.
