Did you see if Jersey Devil can whip one up for you?

You should be able to hold the variator with your other hand to keep the engine from turning over. If too tight, remove the spark plug and feed nylon rope into the cylinder to prevent the piston from completing a cycle.

I typically recommend avoiding Silver Bullet out of AZ for anything. This is pretty typical of them: https://www.utvboard.com/topic/4047-sto ... l-trouble/

I had good luck with an A12 but it does limit upper end speed. I was after torque and was willing to have 30 mph top end speed with my final setup.

I would wait to replace your bore and piston when the original is worn.

Front and rear are the same but rear rim is 2" wider. Use a front rim as a spare and it will fit front or rear. Just make sure the tire height matches your rear tires. The front is less critical if one tire is taller than the other.

4/115mm is the correct bolt pattern. Some of the older buggies used 10mm studs but in 2006 moved to 12mm. If you have an early 2006 model, you may still have 10mm. If you source a different rim, make sure your current lug nuts will work with it or you will need to pack temporary nuts for use with yo...

You need CN250 engine parts for your Roketa.

You can adjust valve lash without the engine running by following the instructions in the Honda Helix service manual:

It will only snap like that if there was play on the axle and hub or if it was over torqued. I doubt this is a warranty issue on an eight year old vehicle unless this was a fresh axle that failed. Contact Joyner USA and Prattville Powersports (bought JMC's inventory) to see what a replacement will c...

Valve timing is set by the position of the cam when the crank is at TDC. Valve lash is set by the two adjusters on the outside of the valve cover. If you did not change to a big bore or anything else, the jetting should be pretty close to what you ran before. Verify what was touched before changing ...

The enriched is just a heating element that pushes out a needle - a t can be wired either direction. Since jetting was fine before, check your valve lash and timing.

What size pilot are you running? You may need a bigger one. My buggy runs a fat pilot 42 or 45 and I have to be careful not to flood the engine.

The Russian Lada automobile uses that ECU version - Try a search on that make of car. Use translate.google.com if your command of the Russian language is lagging.

Timing advances via a spinning weight and by vacuum. Many people block off the vacuum and just set idle advance somewhere between 25-30 degrees based on what runs best for them. More advance may require higher octane and ambient temperatures may affect how much advance you can apply before getting p...

1. Are your shift cable and choke cable strapped together? Maybe the position of the shift cable moves the choke?

2. Is your clutch slightly engaging when in gear pulling your engine RPM down?

Sand takes a lot of torque. Look at doing at least these upgrades: Cold air intake using a 6" intact tract and dual-layer UNI filer and filter sock Long duration torque cam Rejetted carburetor * A ported and polished head will do wonders, but is expensive 12g slider or 10g roller weights in the...

I'm pretty sure my 650 Sand Spider had the battery ground going somewhere to the engine block. For some reason, the Chinese have an aversion to grounding the chassis properly and run dedicated ground to each component instead.
