Hey mate mine came with a gx160 originally so I just just had to re-drill the mounting holes on the original mount. Maybe you can fabricate one up?

No i am just running thr standard crank. Didnt shorten it but had to grind the counterweight to clear the conrod. Take as least off as possible. No balance shaft means less inertia to spin so it gets to higher rpm quicker

Here's the finished product :) https://youtu.be/-0qhKkUgOaY https://youtu.be/-1PDBEQq2yU

hey joekr keep the pics and detail coming. So interesting. Looks awesome. One question.. why solid wheels? That must be rough!

You don't need to but it will improve throttle response instead of being sluggish. You will like it. https://youtu.be/7JbNzoUjpFw Watch this video and pay attention to how he lapps the flywheel to the crankshaft with valve lapping paste...

Also a tip for removing the balancer bearings if you don't have a puller small enough. This is what I did. Couldn't believe it worked! https://youtu.be/nkRmKWktW70

Hey guys, just a few pics from my recent build if anyone is interested. It pulls hard! So much fun. The clutch is getting quite hot so I think im going to run purple springs in it. Has anyone had any experience with the noram star?

Hey Joe could you post a video of you running your engine at 9k rpm? That would be cool. Thanks mate.

Joe405, 9200rpm! That thing must be screaming!!

Hey Chancer I couldn't believe my luck but I actually won the kart at a local tool store that had a Sidchrome competition going. It was setup with a 160cc and wet clutch and didnt have much go about it. Ive done a few things to it now. :wai:

Yeah firemanjim I noticed that after I popped them on. I thought the logo would go to the outside but obviously you can only have the logo to the outside on one side. I dont think it will make too much of a difference for me since I won't be racing.

:iagree::thumbsup:

ok thanks kartfab. Does anyone know what rpm I would be getting with hd springs, arc flywheel, arc conrod and high flow intake with the "stock" cam?

Looks like fun!

Im not sure but I think I may have a 4500rpm rev limiting coil. It is a clone that I bought recently. Im not sure how to tell?

Hey Fabroman, I live in Dysart, QLD. It's a coal mining town. If I go to a smaller sprocket on the axle and are just driving around on dirt, grass and road stop starting all the time I think it would be too much on the clutch. I had a 75 tooth on the back but I did not have enough clearance so I...

Hey guys I have a kart which had a gx160 and swapped it out for a gx390 since I weigh 100kgs. I am running a dry clutch with 73tooth on the axle and 15tooth on the clutch. It has lots of torque which is great but not a lot of top end. I was wanting to know what would be the cheapest route of...
