HOTROD Your Coleman Mini Bike! 13 MPH Speed Gain!

Welcome to my minibike series! In this episode I go over how to hot rod a Coleman CT200U and increase its top speed by 13 MPH! I cover how to remove the speed governor, install and adjust heavy duty valve springs, and installing a performance carburetor kit! But that's not all! Stay tuned for when my friends and I race the mini bikes we modify in the Gambler Mini Bike 100 Mile Enduro!
UPDATE! I've learned and improved a ton since doing this first video. Check out my minibike playlist here: • Motorcycles and Mini B...

Like this video?! Check out the same bike 5 YEARS LATER! It's now an off road monster!

You guys took the governor out the hard way. It is super easy to do if you remove the flywheel first. Then take a punch and push the shaft holding it into the block. Everything comes out with the shaft. Then remove the gear, You can pull that clip off easily, then put the shaft back in the block. Easy Peasy.

I’ll never forget the day I first rode our mini bike as a kid. It had no brakes at all. I drove around the yard and got moving pretty good then wham right into the close line pole.

For those critics out there the duty cycle for mini bikes is completely different than for a lawnmower so removing governor is ok.

Here's a Hint for cold starting any of these engines. With the Kill Switch on Kill... Give it Full gas twice....Crank the engine over twice with the Choke on.... This gets a little fuel sucked into the Compression Chamber AND gets some Oil flowing at the same time (less dry start damage!)

10 years ago, I got into 4 stroke open class go karts. At the time, they ran the 200cc engines. Started out with a cheap clone engine. During the 3 years, I swapped out pretty much everything, apart from the rocker stems. Broke 2 crankshafts, 1 set of lifter rods and rockers. Chewed up 3 stock con-rods. Embedded so much metal into the cylinder wall, I decided to build the engine from scratch. New block and side cover. Genuine Honda crankshaft. ARC billet rod, flat top piston, billet flywheel. Light weight aluminum pushrods, performance camshaft, stiffened rockers. Stainless steel valves, seats and bronze valve stems. Stiffer springs. Was a mix match of different kits available from different race shops. Also, upgraded to a Mikuni VM32. Dunno, how many horses it made(probably 12-15HP), but it got to 50-60 mph on the straights easy in a 150lb go-kart. Moral of the story: never EVER run stock clone parts past 4000 rpm. They will not survive for long, 2-3 hours tops.

liked and subbed, i've been tinkering since i was 7, at 19 bought a bug, swapped the engine on it in 90 minutes. life does throw you some curves, had congestive heart failure 2 years ago, got myself a "valve job", now i'm runnin fine :)

[@sanesaint8725]

Just put a bigger back sprocket so your motor will last, don't take out your governor unless you have money to keep buying New motors

[@goodboyringo9716]

Sorry guys but if you dont install a billet piston rod without the GOV you will blow the engine (at high RPM's ) to the moon.

Lmao I love the US General toolbox with "Snap-On" taped over it

This was much easier on B&S engines from the 1970's. My brother and I defeated the governor on our 2 seat Sears go-kart with an original top speed of about 18 mph. We got it up to about 35, but the engine lasted only about 45 minutes at that speed. It was a thrilling 45 minutes though.

Add Straight pipe Mufler, take trotle screw off, add smaller sprocket, bigger air filter i didnt change my carb .runs nice not hard to start dont have to keep giving trotle to keep it running.

[@MrHanky_YT]

I got a sick feeling in my stomach when you were grinding off the governor arm with the crankcase open right next to it.

Impressive video mate and great editing skills for a youtuber who has this amount of subs, I love it keep going!

[@billlee1724]

Never watch one of your videos, literally thought I was watching a ad for a can cleaning service for a second! That was a good one lol

[@bruin4937]

That was both fun and interesting to watch. There is more involved with the upgrades than I originally thought, but this video should help! Thanks, Jason!

[@samuelhubschman2300]

You guys are awesome love seeing grown men who still know how to have fun!

[@JasonExplainsThings]

Oh man... the bikes got messed up in the race last weekend. Should I do a video about how to fix a mini bike that's been decimated? :-) Video about the race is up now! Go watch it!

[@jfdashley9028]

we learn from our mistakes and can also from each others mistakes. I love your enthusiasm.
