Flat tracking 90 build

[DAM shop]

Any idea on a good brand of tire and tire size to use for a 90 flat track build?

12" cart tire like on the flat track 70's. Are there any tracks near you that have a class for 90's with adults?

You going modern or old school?
If old school is what you are looking for we usually ran 16" or 18" lawn tires. You can pick some up today at the local Tractor Supply.

going old school, thanks for the info. This trike is a 90 bored 5 over, Powroll stroker, ported and polished head with race springs, web 69 cam, hi/lo delete, Jetted 110 carb right now have a 24mm mikuni trying to get jetted right. chrome recoil cover, extended axel, will be going with old school rear fenders. All sitting on a tube frame. Will add this to a collection of two other strokers and a Big bore 110. we have Two more future builds in the barn if we care to do them, we might just sell the parts and let somebody else do it. To many toys.

No tracks.

Good deal on the Old School Build.
On the carb I would start small on the jets ant work my way up. Mikuni's can be kinda hard to tune especiall on a 90/110.
Will it run with the carb on it now and if so what exactly is it doing?

[DAM shop]

It does run now on this carb. I need to jet bigger but for the most part it's running good. I have Mikuni 22 on my other builds with a 30 pilot and 100 main

I was gonna say a 22mm may be the better choice.
You may also play around with where you have the needle set in the slide.
