Thanks for the tip - I will have to think about the 7" as i'll trade better bottom end for a slight loss of top end right? In terms of belts I've read a lot on this forum about not getting the "cheap ebay" belts. The ebay belts for my kart are like $7 vs. $20 from the proper sites that...

I recently had some kind of problem where I burnt out my TrailMaster 200cc TC driver unit. So I went on eBay and found a replacement for that unit. I'm now having a problem with belts getting destroyed after a short amount of driving. I looked closely and the driven unit flat sheave part seems...

So I got the new TC today and added the spacer and then 1/2 driver that goes on the engine side. I then got a straightedge our and i'm a good 1/8" in front of the driven unit's back plate. I checked the series 30 manual and it doesn't explicitly say they need to be parallel - but it sure looks...

Yea I hear you...but yesterday I had to really clean all over. I soaked everything but the weights (that was new) in citric acid solution and brushed all surface rust off. Then I took everything to th wirewheel on my grinder and got it nice and clean and shiny. Kart then ran for about an hour...

Hi - I apologize but I’m not sure how to determine my gear ratio. My tires are 16” and I’m using what looks like a comet 30 cvt clone. Attached are more pictures but i think what it tells us is that something caused the belt to abrade the driver side. We ran the cart for an hour and it performed...

Yea it kinda looks rusty but it’s not. Yesterday it was perfectly shiny once I reinstalled everything. I took it off and it’s very smooth to the touch. Thing is none of this was a problem before I did the upgrades. So something changed when I replaced the zinc weights and reinstalled.

Sorry pictures would help...the belt has been used for a while and no problems before I did the upgrades. As you can see in the pictures the driver faces the belt rides on look like they have some mort of heat damage. When I installed they were shiny and looked like new.

Hi - I recently did a few mods to my go kart when the belt got stuck in the TC driver. I replaced the zinc weight assembly including the springs on the driver unit (connects to engine). One spring was bad and one of the bars was slightly bent. I thoroughly cleaned all the parts on wire wheel...

Yea maybe i'm overthinking it and when I need a part I should just rely on the parts supplier to get me the correct thing. Still kinda bugs me that I don't know the exact engine I have and a service manual with torque settings, etc. To make things more complicated I double checked and my...

Hmmm...i checked the gx200 specs and it’s the same bore and stroke. I guess that at least tells me the intervals should be the same as gx200. Unless the valves and heads and gaskets could be different?. Unless i read it wrong...

Just an update for future info seekers... I tried everything but welding (don’t have welder) including drilling out with some heavy duty left handed bits. Bit broke and got stuck and thought I was done for. Then I read anickodes post and used a hacksaw to get the top of the bolt off. Once I...

Hi - I have a trailmaster mid xrx and I'd like to start some heavy duty performance mods. The engine is black and the only thing I can see as a model anywhere is "168F 6.5" on the side of the engine. The specs from the manufacturer for the engine show 200cc and the following: Max Horsepower...

Really appreciate the offer but I’m in Pennsylvania. Although I do spend a lot of time in Coppel most weeks! Maybe it’s time to learn how to weld? What type of welding would you suggest for small jobs like this that I’ll need occasionally? Dare I try and get a welding setup from Barbour freight?

Is it possible the threaded bolt is reverse thread and I should be turning to the right instead? It’s probably a Chinese knock off of a comet TC....

So I tried the heat but no luck. I was thinking though doesn’t heating the bolt expand it in the shaft and just make it tighter? Or am i missing something?
