FYI: That is a standard Azusa U build it frame. http://ombwarehouse.com/Mini-Bike-Frame-and-Fork-Kit.html

The pitch and space between inner plates is the same but it uses thicker plates which makes it wider. It might hold up a little better.

What size sprockets are you using? You might be able to minimize the problem by moving to a larger sprocket on the j/s in and out. Just a thought.

#40 chain is hard to find in the first place. Most minibikes use #35. Gokarts are all over the place chain wise. I guess you just have to change it more frequently due to the riding conditions. Maybe you should move to a bigger/stronger chain like a #420/428? Sorry i don't have a better answer...

Kartfanatic posted yesterday. I know the OP is from 09.

Please remove all fuel before welding! lol, just take the motor off so you don't die...

If you are throwing the chain, it is either not aligned correctly or it is not tight enough. Scrap the current chain an start with a new section. Make sure it is lined up straight and tighten it enough that you have a quarter inch of play.

5:1 might be a bit much. Are you planning on modifying the engine any? Gov removal, valve springs, etc? Here is a gear ratio calculator: http://www.gokartracing.org/Calculate.htm I use this all the time. I have a minibike that takes me to 42 with a 6.5hp clone (no gov, 18lb springs, rejet...

Nice. I'm sure she will be happy too.

20ga is really thin. I used to be in the metal locker industry and we used 20ga for the body of the locker and 16 ga for the door. The bodies got dented and mangled very easily with little effort. I wouldn't use less than 16 if it were my kart.

Not really, no.

lol, good deal. Don't forget to PM me with the pics of the wheels when you get a chance. Thanks T!

I was just thinking about that too. You might want to put a 45 bend in the exhaust to point down and outside a bit more.

Dude, that is awesome!

Hey BigT, I forgot to tell you about OMBwarehouse.com. They are a great place to find parts for minibikes and gokarts alike. http://ombwarehouse.com/home.php

Just switch the large sprocket and the small sprockets on the jack shaft. It may not be ideal, but it will be better. FYI: Chain Dimensions Chain Pitch Btw Inner Plates 25 1/4" 1/8" 35 3/8" 3/16" 40 1/2" 5/16" 41 1/2" 1/4" 50 5/8" 3/8" 420 1/2"...

Jackshaft out 42 Axel. 21 2:1 8.4:1??? This is all wrong. You divide the driven (21) by the driver (42) and you get 0.5: to 1 ratio. Your final drive ratio would be 2.1:1. You need to get rid of the 42t sprocket and replace it with a 10t sprocket. Can you post some...
