You may have stripped the nut on the crank.

Remove the airbox filter system and replace with a 6-8" intake runner and UNI on the end.

All of these will require rejetting the carburetor, but this is a list in the order I would do them:

Cold air intake
Port and polished head
Torque cam
Big bore kit
26mm carburetor

The right side of the engine uses reverse thread. Make sure you are running your wrench clockwise to remove the nut. I assume you already have a flywheel puller once you get that nut off? The puller used looks just like a bicycle crank arm puller. If the engine is turning over due to the over tighte...

Use regular 90w gear oil. Some transmissions have a fill port where you fill to the bottom of opening, others you fill to the bottom lowest shaft. I'm sure other members will have an approximate volume for you.

You could go with a Joyner metal overflow tank and clamp it to your frame using the proper diameter u-bolts that fit your frame tube:

E650.04.02.02.00

Dorman has a universal plastic bottle: 603-001

Aluminum and stainless 800ml tanks start around $20

The engine is a copy of the Suzuki F10a. You may be able to use some parts locally available for the G10 or G13, but I am not sure you can use a G13 ECU in a F10. Perhaps Klug has wiring diagrams you can use to check against your buggy wiring. Roketa and BMS also use Goka based buggies, so look at a...

There was an issue with the external actuator stripping out on the shift shaft on some units. Make sure the transmission is actually shifting and the cable is just not moving a stripped out part.

I try to avoid adding negatives because I am really non-plused about them and usually end back up at zero.

Can I just add some diesel to the tank to lubricate that bearing?

Leave the clutch arms with stock springs. If you were racing, you might see an advantage - But it will slip the clutch more under load and wear it out faster.

12g slider or 10g roller weights with a red main contra spring will work well in the transmission. Remove the airbox and run a dual layer open air filter on a 6-8" intake tract to improve breathing. You will most likely need a 120 or 125 main jet in the carburetor to compensate for the addition...

I followed your previous problem and topped off the water, but it didn't help. Was I supposed use oil instead?
