New to the Forum as I've just purchased our first karts.

I have 3 boys ages 8-15, we have dirt bikes and atv's which the boys enjoy riding. I started looking at getting a go kart as a project for all of us to work on. Well I ended up getting more than I bargained for.

I started my search looking for a single seat kart that was in decent shape but stumbled on a bargain that I couldn't pass up. I'm now the proud or shell shocked owner of (2) 2006 Manco Scorpions both with the Subaru 6.5hp Robin engine.

I'm feeling a little over whelmed at the moment with questions of normal maintenance, normal breaks or wear points, and just a good rule(s) of thumb for up keep.

Any opinions or pointers would be greatly appreciated. I'm hoping the boys can enjoy their new toys without too many problems.



thanks.

Manco is a good kart and are not nown to have many problems. i myself have 3 manco silver fox gokarts which are very similar karts to the Scorpions and i love them. the only problems i have with my karts are all the same... keeping up with general maintenance. i cant stop riding them.:)

I'm seeing a lot of references to belt replacements. Is there "normal" hours of use limit on the belts or is it highly dependent on the engine, TC, use....

Also, what am I looking for when it comes to warn belts? Missing teeth, shredding, or do they just come apart during use?

Thanks for in the link! I'm picking the karts up this week. The guy was moving and I got both karts for $700. I didn't need to 2, but I also couldn't walk away from the deal. He kept them in his garage and took care of them, so I'm hoping we get several years of fun out of them. Now I just have to figure out where to put them??

Is there a link or thread about kart drive (TC) basics? I don't know a lot about the TC or how that whole assembly is supposed to work.

thats a good buy for $700 i payd $500 for one of my silver fox's and $450 for the other and onemore i got frome the scrap yard for $50 and thin put $10 in to it to get it to run. as for how the TC works im going to say google it.:) or maybe sid will tell you how thay work.

How does a torque converter work? The drive clutch is activated by centrifugal force from the engine crankshaft. The moveable sheave of the clutch is forced in as the RPM of the engine is increased. This contacts the drive belt. The drive belt will then be forced to a larger diameter within the clutch sheaves, thus pulling it to a smaller diameter within the driven unit sheaves. The moveable sheave of the driven unit is forced out, allowing the belt to seek it's smaller, high speed ratio diameter. As this happens, the speed from the engine transferred to the final drive is increased.

The asymmetric torque converter components use a 3/4" top width belt. The belt mass is desirable in applications requiring extra rugged driving ability, such as dune buggies, go karts, mini bikes, ATV's, grounds maintenance equipment, materials handling devices and industrial equipment. It's mounted with both stationary sheaves inboard requiring only minimum displacement.(All the working parts are on one side.)

The asymmetric type torque converter system has sheave faces that have different angles. It uses a belt that's flat on one side and angled on the other. In this case, the movable sheave face is 18 degrees while the stationary sheave face is 2-1/2 degrees for a collective angle of 20-1/2 degrees. By having both the driver clutch and driven pulley fixed sheave faces on the same side (inboard) the system can be mounted on a fixed plate, in the same plane. See the 30 Series TAV2 Complete Kits. This offers some very significant advantages to mounting requirements in many cases. Noting the displacement diagrams you will see that the torque sensing cam assembly is mounted outboard adding further to the convenience of many installations with displacement problems. The asymmetric concept, having the 18 degree angle on one side requires less sheave face travel to lift the belt to larger, comparable pitch diameters of the symmetrical system. This makes it possible to force the belt to a diameter within the drive clutch (at high RPM) that exceeds the usual 1:1 ratio of standard systems. The 30 Series parts on this page are interchangeable with the 30 Series TAV2 Complete Kits which use an Asymmetric Driver Pulley and a 6" diameter Driven Pulley.

The spring and flyweight assembly in the driver clutch actuates the movable sheave and responds to engine RPM and should be replaced if the pins or springs are even slightly loose. If they are not VERY tight the loose pins and springs will prevent the pulley from disengaging. If your machine tries to take off by itself you may need to replace this part. Other problems that could be causing the system to be engaged all the time: dirty components with a lack of lubrication, worn out splined hub, the drum not correctly installed or a weak spring in the driven pulley.

wow... I'm going to read that again after 1-2 beers. :ack2: :cheers2:

Thanks for the links and the explanation. I'm looking forward to testing the machines out (famous last words). I have to cut a track through the tree rows this weekend and turn the boys loose.

Are the shocks on these things adjustable?? I know the ones on our youth quads are, but I couldn't tell by the pics and I didn't think too look closer when I was checking the karts out.

Welcome to the forum, great deal on the karts :thumbsup:

Basic maintenance is just like a car, regular checking of the
-oil level/condition,
-air filter,
-control linkages/cables,
-brake pads

Sweet deal. They look like they are in great condition. General maintenance should not be too much of a problem. Fabroman covered most of the basics

One of the things I'm concerned with on the Karts is the front wheels. Where we ride isn't bad as far as rocks or really rough terrain, but I'm saying that with our only experience being with the youth quads and dirt bikes. What kind of performance impact would there be If I wanted to put bigger wheels on the front to help smooth out some of the bumps?

I understand there might be more rolling resistance, but would it throw the handling/performance way off, or maybe improve it given the terrain? With only 6.5hp I don't want to slow the kart down to much, but I also don't want to shake the thing apart. We take care of our toys, but with three boys they get driven hard.

The only adverse effect to changing the Font tyres is you raise the front of the kart.

Here's a simpler tip: The current tyres have rather tall side walls so, lower the air pressure in the tyres, this will create a cushion effect...
