I already have one kart with a lightly modified 212 hemi that I left the governor on and it is plenty of fun but I recently was gifted a second kart from a friend and and wanting to build a more aggressive motor for it, it's going to be used off-road with some decent hills so I'm wanting to go...

Hey Guys. What is more important ? Having the rear wheel centered in the frame or chain alignment ? If I center the wheel I'm off about 3/8" between the clutch and sprocket. I can offset the wheel easily with spacers but it will take some surgery to offset the engine which is pretty much...

Maybe a dumb question.....Ill be looking for a Tecumseh engine for a 2 speed mini. I know that the clutch will be secured with a bolt thru the clutch, into the shaft. Does the shaft of the engine have to be a certain length. Thanks in advance.

I have been working on an old Manco TrailCat. The frame has been cleaned up and painted the engine is a completely stock 3 1/2hp Tec side popper. My problem is that the air cleaner housing hits the rear fender unless the engine is completely forward in the adjusting slots. With the engine all...

Hey guys, newbie here to the mini bike life. Just picked up the Coleman CT200u which I believe is a gx200 6.5hp clone. What are some of the BASIC things you guys did when you first got your bikes? How about replacing the Chinese spark plug it comes with , a LD-F7TC is oem plug. What's an...

Hello, I have a 1971 Speedway Shark mini bike with a very tired 3-hp Techumseh engine. I'm thinking of swapping the engine to a new $99.00 China unit from Harbor Freight. I'm concerned because my engine is mounted at an angle, the Techumseh intake manifold is angled so the carb float is level...

Just wondering if anyone has replaced there Rupp seat covers. I bought one from ebay and it came with some button things that you apparently push through the fabric and then bend the tabs on the other side of the seat pan to secure them. Do you drill out the old snaps on the metal seat pan and...
