questions about new mini bike

[Everett]

This Is for everyone who is just curious about mini bikes but doesnt have any experience... like me.


I just got a new colman with that hisun motor. I use it for climbing mountains and work. I have removed my govenor for reliability. How far can I go without upgrading the flywheel.

You removed the governor for "reliability"? I removed the cats on my Stang for better emissions too,

Hello @Everett ...welcome to the Oldminibikes.com forum.

By limiting the achievable rpm's, the governor is what keeps the stock flywheel, and connecting rod from failing and imploding.

For safety's sake, you have gone too far already.

One solution is to install a torque converter. It will keep max RPM in a safe range on that bike governed or not as long as you keep the stock gearing.

Yeah lol I had already had problems with it jamming.

Yeah I Understand that is foolish to to but like I said I had already had problem with it and I Wanted a little more speed

And if you like your lower right leg to remain connected to your body you should reconnect that governor..

I would really like to install a cvt and I probably will. I am curious about the flywheel fracturing.

I plan to install 18 pound springs and some basic engine work. I do not wish to hotrod it becuase Like I said I use it to climb mountains Mostly. I have heard of people using those timing keys to get a little more low end torque. Are those dangerous?

I was never a huge fan of it anyways tbh do you know anything about those timing keys?
What do those effect as far as low end torque that is really what I Am looking for.

You mentioned the connecting rod imploding. I have not heard of anyone upgrading the connecting rod even after achieving greater than 6k rpms. But yeah the flywheel is a concern

Torque converter and the bike will feel like a 125cc motor cycle.

There are some good pictures of that. Lol

This is why you don't over ride a governor

You could see the magnet bounce off the gas can and land on the floor.

This is a flywheel EXPLOSION. Flywheels explode and they dont care what is near them when they do. The previous video only shows the magnet coming off the flywheel.

Thank you , I could not find the good ones. I'm still looking for the one that shows the guy's leg. I think YouTube blocked them.

Get a Tachometer and stay under 5000 rpms and it will never blow up !

I see that definitely looks dangerous.
