Greetings, just found your channel. I have 2 mini bikes, one is a Massimo Warrior mb200 (which is a rebranded baja warrior) it has a predator non hemi 212cc wit a billet flywheel, +.020 billet rod, hot265 cam, thin head gasket, stainless steel valves with 26lb valve springs, and a vm22 carb. My other is a trailmaster mb200-2 with the factory 196cc with the billet rod and billet flywheel, cm cam, 26lb valve springs, and a vm22 carb. These are great little engines with a few mods

Welcome aboard!

[@spuds7677]

I am building a Ducar 212 and I will be doing all of this tonight. 275 cam, billet Rod, 24mm carb and exhaust, should run pretty good for my needs.

[@MikesGarageShop]

That is exciting! Is it for a minibike?

[@Deucealive75]

The choke lever to the left is choked. Moved to the right is choke off. Pulling the governor is never a good idea unless you do not care about shortened engine life and the possibility of catastrophic failure. Governor removal should only be done at the time of an engine build. There's nothing wrong with the governor/throttle linkage. It's a 30 year old Honda design that is still used to this day. The only negative is the Coleman return spring which is too long and can bind. I shorten the spring and use a small spring like you used here. I run built engines with the stock linkage and governor. Both bikes are 45 MPH plus. One of my bikes runs to more than 50 MPH at 5600 RPM. The Hisun 196 is a good quality clone engine. Easily a better quality engine than the 196's that Harbor Freight sold prior to the Predator coming out. It's too bad so many of them have been abused and ruined then called junk by those who ruin them.

You didn’t remove the washer that’s on the govern wheel shaft. It will vibrate and ruin the engine eventually.

[@brianparker8031]

I’m sure people have already said this but you know you still have it on choke it runs better with choke off

[@Joe..3.8.0.9_]

If you do pull the governor , you need to put heavier vavle springs in , i believe 18 lb springs and yes there was nothing wrong with that governor

[@user-gt3xx6lc1o]

1/4" hole is smaller than standard for 5/16" tap😂

[@user-gt3xx6lc1o]

That dark inboard spring looks to have too much slack in it as if its in wrong hole

[@indianachrisUDX1313]

Liked and subscribed!

[@davidbjerrum6178]

also instead of drillin and tappin that old governor hole you could have just cut the arm off the shaft and put it back in the case. that way if a governor is ever wanted to be reinstalled the hole isnt all messed up. just sayin

[@user-gt3xx6lc1o]

Lots of sketchy stuff here good idea to put a couple sizes bigger pilot jet in while working on carb. These engines are notoriously lean from factory for epa reasons and they start much easier with less choking.

[@2bskor6]

You need a clutch. A common problem nothing to do with the linkages. As others have said turn the choke off when it warms up.

[@bigram7235]

I have the exact bike one ride and the throttle was stuck open. Exact symptoms your was having. Did you ever locate the problem?

[@jonlambshead5115]

That Fly Wheel Is Weighted For A Governed Engine , It Needs A Aluminum Billet Fly Wheel, A Much Lighter One Because Of The RPMs It Will Be Doing. That Heavy Fly Wheel Doing Those Kinds Of New RPMs Will Get Destroyed & Do Major Damage To That Engine. That Old Fly Wheel Is Not Designed For That.

[@MikesGarageShop]

Jon I have to disagree. I’ve seen lots of ungoverned engines run with their original flywheels and never cause damage. You’re not in the business of selling aluminum flywheels are you?

[@jonlambshead5115]

@@MikesGarageShop Ha Ha Ha . your Funny. Ok You Will Find Out Yourself

[@user-ru7he6qj2w]

@@MikesGarageShop the magnet is glued on, hes not wrong. Ive seen them blow up. Just get a 30$ pvl flywheel and never have an issue again

[@Deucealive75]

@@user-ru7he6qj2w Not only that. With enough run time above 5K RPM he's going to ruin the rod. And what they do is run it right into valve float then find out from youtube videos that they need 18 lb valve springs which makes matters worse. It's a shame because the Hisun 196 is a pretty good engine. I just opened my nearly 7 year old Hisun for a mild performance build and it looks great. It will get a billet rod and cast aluminum flywheel.

[@noxxy3676]

Hello I have the same problem of when I turn it on it was to go but what happend was when I was riding I found the throttle return spring on the ground bent it a little then put it back on and the. It stated making the problem

[@timbates5320]

Great video,keep up the good work

[@MikesGarageShop]

Thanks!

[@vedysneakysnake6155]

Will the link to that whole pull start mechanism bolt right on to the engine or will I have to just replace the coil

[@MikesGarageShop]

I’m not sure what link to the pull start you are talking about? The pull start will not get in the way of the new throttle set up.

[@georgerossier]

Who is going to tell him

[@rickduncan2929]

I did

[@jayhouston1614]

How are you going to repair anything when you don't understand the mechanics of the choke?! You now have it in the on position which helps you start it and then you move it right to the off position to see if it stay running! It will not go nor sound right when you give it gas! 😂😭🤣😭😂😭🤣

[@butcherknife59knife46]

Nice watching you trouble shoot the problem. I hope you removed the washer on the governor it just setting behind the weights. Iv’e watched a few and just my observation. Carry on

[@MikesGarageShop]

Thanks!

[@Joe..3.8.0.9_]

Wrong turn chock off !!!!! It was off ,!!!!! Leave it !!!!;;;

[@barrydavidson6249]

Duh

[@quintinalvarez3922]

There wasn't anything wrong with that bike the governor was on the whole time. You took that bike apart for no reason. But you live and learn.

[@Deucealive75]

That's an incorrect assumption and not surprising. It's clear that the owner of the bike worked on it trying to get more speed. And then gives the bike to a guy who doesn't know what he's doing troubleshooting with the choke on. That's a 15 minute fix and a faster bike when done, if you know what you're doing.

[@aydenleyva8156]

Take the choke off

[@858415]

Slap on a $30 vm22 carb and be done

[@MikesGarageShop]

I can see that as a solution. Some people love diagnosing the problem, some like to use it as a reason to upgrade.

[@fuckface8944]

Hey mines has a governor delete and it’s stuck accelerating can’t get it to stop it’s just stuck in gear any info anyone ??

[@MikesGarageShop]

Is the throttle stuck open? Take off your air filter and inspect the throttle plate or slide. Does it move forward right away? The clutch might be seized. KZbin search those items to help guide you if you need help.
