Get an in-line fuel filter and you won't have that problem again. I wasn't using one on my brand new engine and managed to clog up my main jet in my carb. I ordered an in-line fuel filter and haven't had a problem since. My tank is also old and little rusty(haven't gotten around to cleaning it)...

Try this: Put the bike on a stand. Start the motor and let it warm up a bit. When it's warm, twist the throttle. If it revs higher with no load on the bike, you need a higher gear ratio. If it still doesn't rev any higher, it's an engine problem and not your gearing. You are currently at a...

The gearing looks like it about a 1 to 1 ratio. Flip the jackshaft sprockets around. Engine should be small on clutch to larger on jackshaft. small on sackshaft to larger on wheel. It looks like you have small to small and large to large. Your clutch will never lock up with that gearing.

Wrong, that screw only adjusts the travel of the hand throttle and limits the rpms to lower than 3600 rpm. The governor controls the max rpm. If you want to adjust the governor, you have to remove the gas tank and play with the governor arm that goes inside the engine. Most frown on this but it...

72 T should do fine. How much do you and the kart weigh?

I found this site a while back. They sell dune buggy and sand rail parts. Thought you might want to look at some rack & pinions. They are fairly cheap and well made. http://www.desertkarts.com/productCat40912.ctlg

Why don't you just get a blue you like and repaint the tank and engine parts at the same time? I'm planning on doing just that when I build my mini bike or quad.

I tend to agree with you engineer. If you do use this idea, definitely weld the loops.

I just looked at one of those at HF the other day. If it is connected to a little black box with a yellow wire, it is the low oil cut off sensor.

****, I was just going to post that... lol

Yes, I was at work and got distracted by my boss. I was also going to say that valve springs would not hurt. I have been told that the stock springs can't keep up with anything over 3600 rpm. Either way you go, you will spend some money on a clone but the up side to that is that you still...

Sideways makes several valid points but a flywheel and rod are a good safe start to modifying a clone. I would also add an exhaust and intake to help it breath.

I'm also interested in a tall bucket seat so if anybody knows where I could find one, It would be helpful. Lefty

Start with scrap metal and play around with the mills. Be prepared to buy a few mill bits because you will destroy a few before you get a feel for the materials you work with. You want a higher rpm for harder metals and slower for softer metals. Just go slow and you will be alright. Set your...
