- Filmed over a two year period, join Matt as he gets his good old Baja Dirt Bug mini bike up and running again. Staying true with his love of keeping things original, he goes the hard route to get a little more torque out of this micro-beast. Enjoy!

i love a good lesson on minibike motors. thank u so much for putting the math on screen too. your way of explaining things along with the visuals really helped me understand everything. like n sub!
Wow!! Thanks for such a nice comment!! I’m glad you enjoyed and thanks so much for subscribing. Take care!!
I have a new Coleman ct100u , 3hp engine.I put a tachometer/hour meter on it so I don’t over rev it.
Thanks a good idea! Keeps the engine alive longer!!!
wich app do you use for the speedmeter
love the video btw
It’s called “Speedometer” by Tim O Studios llc, in the app store. Glad you enjoyed! Thanks for watching!
Baja doodlebug....these are great I have 3 of them....
Glad to hear! I really like mine. They are a simple, affordable and fun little ride. Thanks for watching!
That's known as a Doodle Bug here in the states. A tough, popular bike that is very easy to modify. The commom trend is to 212 swap them. The little stock engine is great though if you just like cruising around.
Thanks for the info! Honestly, with the lack of suspension, I wouldn’t want to go much faster than the stock engine can give… The 212 mod would be best suited for a teenager who doesn’t mind a sore back! Thanks for watching!!!
@@mattsws Hi Matt ...what's the CC of the stock Engine ?...did I here you say 97cc ?..Thanks Trev New Zealand 🤗🇳🇿
@@mattsws Matt...you can put stiffer springs in the stock engine's clutch so it revs up higher before the clutch engages, especially for heavier kids, you don't need the 212 Predator unless you are going to modify it Or like gobs of low end torque : I'd advise a Torque Converter if sticking with the Stk Engine with heavier riders..cheers T
@@trevinskiking2165 Hey man! Yeah its a 97cc engine that puts out just under 3hp!
@@trevinskiking2165 You are absolutely right about the stiffer springs! It ended up being a lot of work, but when I made this video I was set on my idea of using a bigger sprocket. Work out well, but the springs would have been easier! Thanks for watching!
So it doesn’t seem like a huge torque increase?
Just enough to make taking off with me on it (175lbs) doable without using your feet to push off… I think it was worth it.
@@mattsws is it alot slower ?
you look like freddie dredd
That’s the nicest thing I have been told in a while…. Thanks for the compliment and thanks for watching!!! Lol
Very wrong about the knock off parts, but that's your uniformed opinion
Ok boss!
8:50
Thanks for watching!
If I was you I would cut the fat part of the sprocket hub off with a hacksaw then weld and grind the crap out of it
Yeah, that definitely would have been easier… Thats why I called the video: The hard way!
Find a washer that fits the big sprocket weld it up drill holes
That would have been too easy! I wanted to do it the hard way!! ;)
I got the same engine and go 30-35 mph
Yeah, if your light enough and you have the gov removed, you can’t get them going surprisingly fast. Thanks for watching!
Had exact same engine, replace carb with $13.00 adjustable carb (non epa) on Amazon. Also air filter plastic cover way too restrictive, cut some slats out of middle air filter cover. Went from 27 mph to 32
It’s surprising what you can squeeze out of a little 97cc engine! Thank for the comment!
Good video man !!!
Thanks!!! Really glad you enjoyed!
What did you search up for the carburetter ?
Type “97cc carburetor” and you have a bunch from all different sites! Thanks for watching!!!
Bon video bud 👍✌🇨🇦
I’m glad you liked it! Thank you so much for watching!
Just bought my daughter a nice used one today for $150. Came right home and ordered a new carb throttle grips and cable for $18 new air filter for $15 (the carb and air filter were missing). Probably gonna order new brakes and chain after I get it running. Hers is a Baja blitz
Yeah, that is whats great about these little bikes. All parts are available and super cheap!!! Never takes too much to get them running AND they’re great fun!!! Good luck and thanks for watching!!!
@@mattsws ordering a Mikuni style carburetor and header for it now. The carb it has kinda sucks with very little throttle movement. It’s almost idle or full speed. Deleting the governor when I put the new cab and header on it.
@@GratefulEd907 Awesome!! Keep me posted on how that goes!!!
@@mattsws I just did the 212 predator on my mine over the last few weeks only working on it here and there and waiting for new gasket but got it back together and just fired it up for the first time 20 minutes ago so I feel confident I can do hers too. But yeah I’ll come back and let ya know how it goes.
I’m having so many issues with my throttle assembly. Can anyone help
Yeah, whats going on?
@@mattsws idk if you have Instagram. I could send you a pic to make it a little bit easier. But there’s like no adjustments I can make for it to run properly. It’s either to tight or to loose. I either need new springs or a throttle cable. I could also be missing something I’ve been watching videos on them and nothing seems to help.
Sorry, don’t have Instagram… Take a look at the video at about 9:00 mark. You can see how smooth the throttle should move. A few seconds later, you can see the governer linkage assembly below. Pause the vid and make sure everything is hooked up the same. If that doesn’t work and the movement is still stiff, you might have to change the throttle cable. This can happen is the bike has not run in a long time and has been left outdoors or in a damp place. Hope this helps!
The engine is a Chinese copy of a GX-100
Thanks for the info! Its the only chinese clone I have and despite my belief that they are inferior to OEMs, this little guys has always started and ran great. Doesn’t even burn oil! Maybe I got a good one! Thanks for watching!!!
Build a fast minibike!!!
With no suspension and a rough terrain, I can definitely say that 16mph on a kids minibike is fast enough for me!!! Thanks for watching!!!
