Just got a torque converter for my gx390 but the backing plate bolts are a different thread pitch than the motor. Can somebody tell me what bolts I need to get to mount the backing plate to the motor?

I’m trying to add hydraulic brakes to a go kart that wasn’t really designed for them and adding a master cylinder that requires a pull on the rod instead of a push would be a lot better so that I don’t have to build a complicated lever system. However I haven’t found one online. Does anybody...

So I’ve built a couple of go karts by buying run down frames and restoring them and putting on some upgrades. This has been a lot of fun and the karts are not bad but stuck within the limitations of the frame. (bad Ackerman caster and camber angles mainly). And a lot of weight. For my next...

Today I tried to improve my braking system by creating more leverage but somehow it got even worse. Before I could lock it up with enough force but now I can barely move the pedal. What I did was weld in a longer pivot rod going to my caliper, about twice as long but it seems like it has greatly...

So I think I may have been oiling my clutch wrong can someone point out to me where I’m supposed to be putting the oil and any other things I might be doing wrong? I’ve been putting a drop on my finger and rubbing it around the piece on the left where it rests on the shaft. I do this every time...

Well I’ve tried everything I know so far and my hydraulic disc brake still can’t stop my cart. I noticed only one side of the rotor has marks from the pads and the outer pad (the one not pushed by the cylinder) is the only one that is showing any wear. I have checked the slide pins,they move...

I’m running a stock gx390 and looking for more power. The problem is I need to keep it quiet because I mostly ride around my neighborhood, but everyone says the stock muffler is terrible and it’s the first thing that should go... so are the other bolt on mods a waste of money if I’m keeping the...

I have two Honda engines a 240cc and a 390cc and I was wondering if I can swap the smaller head onto the bigger motor for more compression. Does anyone know if this will work? I’m also looking into some other upgrades like the cdi coil and porting the head myself. Unfortunately I don’t think...

So I just put A new clutch on my 13hp go kart and it shakes like crazy when you’re accelerating but as soon as you let off it stops. I did some research and most people have vibration problems but this is a straight up death shake. I killed the the motor after about 30 seconds because it was so...

Alright this is a wild one. Just got my restored 13hp go kart running and it did great today. But while cruising back home the mounting plate completely snapped in half. I’m thinking maybe the chain was too tight? Also the torque converter was too hot to touch, is that normal? No idea what...

Hey I just finished rebuilding an old go kart I got for free. Most of the parts are brand new. (Live axle disc brake sprocket. Hubs bearings torque converter carburetor.) the motor runs good and with the rear end jacked up the motor will rev up to max rpm with no problems and the wheels will get...

I just want to get some input on the design of this frame because im new to all of this. Are there any obvious flaws in the design? Does the cage need more bracing? The shocks sag when a heavy rider is in the kart, Relocation? Drivetrain is a honda gx240 w/ torque converter and 6:1 gearing...

Hey guys I need your help. I recently finished building a go kart with a honda gx240 motor. I love the power compared to my old 6.5. Well yesterday I was given a gx390 because it was "broken." It ran just fine when I put my carb on it. (gx390 Carb) So my question is: What parts can I use off of...

I have a honda gx240 8hp. The motor sat for about 15 years. I have completely restored this motor, so it is basically brand new. I also have a carb from a honda gx390. The motor runs pretty well but it is hard to start. Whenever you first start it up it seems like its idling low and wants to die...
