Your build and tinkering videos have helped me out tremendously. Great work keep the videos coming.
That's cool! Thanks for comment ✌
I would take 1/16” off each of the spacers. Won’t cause any problems. Then you have a full 3/16” less of tension when trying to reassemble.
I think you're right! Next time I have it apart I'm grinding the one on the right down for sure. Maybe some on left if needed. I want that rear sprocket as far right as possible in case I do a TAV conversion, but then again, can use washers to play around with spacing anyways.
They sale a syringe at the parts store in the grease section that you can stick on the end of your grease gun and stick the syringe between the ball bearings and it'll spread the grease in between those bearings perfectly.
Yeah I have some big syringes like that actually. Could have used one.
If you pull the bearings out. Remove the inner seals then you can install a grease fitting on the axle to keep it lubricated.
I was just struggling with the same exact thing, the tensioner and brass bushing. I was trying to think of what the heck to use. I was able to fit an indexing pry bar in there and get it up and in no problem.
Well glad it’s not just my bike but too bad they made it like that. I’m gonna shave down that outer right spacer, maybe the one on left a little too. Maybe try to pry the swing arm tubes apart a little too. I ended up just prying the tabs apart a little when I tried that in the vid.
Wow Today’s Just Has To Be The Day I Was Going Down The Highway And My Chain Comes Off
On MB200-2? I think they could use a chain tensioner even stock. On my first ride it felt like it almost came off twice.
The huge sprocket angle is what causes the loose tight issue not the shocks they are always compressed when riding there no tight loose issues with 36 to 50 sprockets

Check this vid at 8m 16s: th-cam.com/video/_OP7e2Or_Ug/w-d-xo.html
You're not the first and you won't be the last to think that. I'm not picking on you specifically, and I appreciate all of your comments! This response is for anyone who is interested.
Shocks aren't always compressed when riding, they go up and down while riding, a lot.
The distance between swing arm pivot and front sprocket is the main problem. If they were lined up, (front sprocket in line with swingarm pivot looking from side of side of bike) there would be no problem at all, it's simple geometry.
The longer shocks add to the problem, causing swingarm to travel even farther down away from frame when fully extended, making chain even MORE loose when suspension is fully extended (like when you are in the air, after hitting a jump). When you set chain tension with swingarm extended, it BINDS up when suspension is compressed.
Another way to combat this if using longer shocks with more travel than stock would be to raise the shock mounts. That would not completely fix this fundamental geometry problem, but it would help somewhat at the extremes of swingarm travel.
Size of rear sprocket doesn't matter that much if at all. This problem will happen regardless of rear sprocket size. It's the angle of swingarm in relation to front sprocket that's the issue. That causes the distance between front and rear sprocket to CHANGE while swingarm travels up and down, lengthening the distance when swingarm goes up (until it passes the center point of the arc path), and shortening the distance when swingarm is extended. It's the same sort of thing that causes bump steer on incorrectly designed or heavily compromised front suspension geometry. It's a fundamental geometric misalignment.
So stock bike has less of this problem than bike modified with longer shocks, but the problem is still very much there on a stock bike with stock chain length, stock sprockets, and stock shocks. The problem is just compounded and worse with longer shocks. You just can't ignore it anymore with longer shocks, things will break quicker.
Most people just do nothing, and set the chain tension way too tight while swingarm is fully extended (at rest). Then their chain constantly derails and ends up breaking, their wheel bearings and jackshaft bearings constantly get destroyed, and their rear suspension is limited and not working correctly because the chain tension becomes a "bump stop" on the rear suspension as suspension compresses. Chain tightens as swingarm travels upward- that is the problem, but it's pretty bad on this bike.
Even the big channels like Cars and Cameras, Reg Beard's Garage, and Gopowersports don't seem to get it yet. BTW I love their content.. it's awesome, and I don't have a bad word to say about any of them. I've learned way more from them then they'll ever learn from me.
BUT... they all constantly throw chains and break chains / destroy jackshaft bearings on their MB200-2 / Hurricane builds. Even when they build a bike to go race for competition, the bike is usually broken and stopped because of broken chains and chains coming off. It's chain tension binding up at top of swingarm travel that breaks things. It's an immovable object (chain tension) against an unrelenting force (swingarm travel). Something is going to break.
But whoever designed this frame also didn't understand it, or else they did but were constrained by packaging issues or some other reason I haven't thought of yet, and did it on purpose.
Either way I knew about this issue years before I bought the bike. It's the main reason I didn't buy one sooner and one of the main problems with this bike IMHO. I almost didn't even buy the bike because of this problem.
I gave a visual demonstration of the problem in that vid link above and have completely fixed it with a chain tensioner. I did not discover this issue, it's a known issue. In general that's why some bikes need tensioners and some do not.
@@bwxmoto Oh I'm not worried about it most of what you say is probably correct I'm just saying i race high horse power drag motorcycles and racing motocross the last 25 years and I've come across these simple issues now and then when changing sprockets struts and shocks
@@kenjuicekrajewski9577 That's cool man I probably misunderstood your post anyway. I never know if I'm talking to a 9 yr old kid or an expert.✌😆 Now that I look, I didn't mean to post all that LOL. Sometimes I get bored and just keep typing. Bad habit!
@@bwxmoto i know all the keyboard experts that never did or built anything or raced anyone etc its tough but you know what your doing just keep doing it! Its all good!!
you should pop the bearings out by the outer race, and put them in a ziplock bag full of grease, and then seal the bag and then work the grease into the bearing by pressing and working the bag.
Once you remove them, they’re pretty much garbage. I just use new ones and pack the new ones.
@@bwxmoto not if you pop them out from the other side by tapping on the outer race. its odd that they weren't sealed
Not all greases are compatible with all other greases. When non compatible greases are mixed togeather they create acids ect and you are most likely doing more harm than good….however if you were able to get all the old grease out and replace it with a better grease , then you are on to something.
Yeah I realize that but I've experimented with different greases and doing this is way better than not doing anything for these cheap bearings. The synthetic grease doesn't seem to interact with the tiny amount of vaseline they put in these.
If it doesn't work, I'll just change them out, which I would have to do to get the old grease out anyways. And the way I remove bearings destroys them so that's pointless.
I guess you could take the seals off and blow the grease out with air and spray some solvent in there to dissolve the grease but that's a lot of work for a $2 part on a cheap chinese mini bike when just squirting grease in there does the job.
Not really a hard job changing them out either though.
All mb200 trailmaster rear is tiight like that even my own trailmaster lol
Snap! Just kiddin
😆
Dont let the struggle give you a bad impression on the MB200. I am looking to put the Coleman 50t on my MB200 I will do a video on it and let you know how it worked out. I really like my MB200 it serves my purpose.
Oh yeah definitely. I think after I file down the right most bushing on the axle it should go together and come apart a lot easier. Something is definitely jacked up with the spacing on mine but it doesn't affect how it runs. 👍
@@bwxmoto spacing on mine is the same as yours.
@@stinkybritches4540 Yeah I bet if you file a millimeter off of the outer right bushing it'll help a little. Next time my wheel comes off I am doing that.
And I might also take a little off the left bushing if it doesn't help enough.
@@bwxmoto I’m definitely gonna shave em next time I need to pop the rear off. I wrestled with that thing way too long.
So I got mine back together the right way after upgrading my sprocket. However, I got the M8 x25 nuts rubbing against the brake rotor and causing the wheel to not rotate. Is this because I have too tight of a swingarm?
I'm not sure, it's been a while since I have looked at it. Could be spacers are not installed correctly, that seems most likely! Is it the end of the bolts? Maybe wrong bolts? Hard to say!
@@bwxmoto part 3 of this video series answered it. Actually. I had the spacers correctly, but between the two spacers facing the brake rotor side, you're supposed to have that bracket that holds the rotor in between the two smaller spacers. I figured that part out, but I would have screwed up the proper chain length if I didn't watch your video on how to compress the shocks. So I already discarded the original shock. So what I'll do is just disconnect the shock from the sprocket side. I have a chain tensioner and a chain guide. Keep the videos coming. They're good and they're detailed
@@Midlifecrisismods Sweet! Yeah lots of people destroy chains and bearing and stuff if chain is too tight when swing arm is extended. But yeah chain tensioner works great on this bike. I haven't touched it since I put that steel roller on and got spring adjusted right. Yeah I still have stuff I want to do to this bike this summer so I'll probably do another vid and update on it at least. ✌
@@bwxmoto hell yeah I'm putting a super modded Ducar 212, pairing it with the juggernator as well premium front end suspension kit from Go Power Sports, plus a real gas tank. It's going to be my main cruiser. Your videos are influential to the mb200 hurricane community because of the documentation so well that you do. Everyone tries to act like they're Emeril. Lagasse leave the main secret ingredient out and say bam and post a video of their badass rig. However, they never show you the secret sauce LOL. Even the exploded view straight from Trailmaster on the rear wheel assembly is vague. Even if you follow it to the T, it doesn't show that that brake spot goes between the two spacers that's for sure
@@Midlifecrisismods Thanks man! Yeah I'm just trying to help people and make a vid that has some actual value to someone, especially when I come across problems. I try to only cover things I'm pretty sure about, at least at the time, and make sure to say if I don't know for sure. I could slap engines together and get more views but there are other people that are much better at that. LOL
These bikes are simple but still, there's lots of little things that can go wrong when you start modding them especially when someone is first starting out working on things in general. These vids are aimed at people who haven't messed with these before or people who have and just want to see how someone else does it. I'm no expert mechanic but in certain areas I hope I can help. ✌
Just went through the rear wheel installation drama last week. Next time gonna grind each spacer down about a sixteenth. I can always add a shim or washer if I take too much off a spacer.
That was my thought too. Going to try to take as much as possible off the left one.
I grinded 1 millimeter off each spacer, reassembly was easier. I noticed the chain tensioners have a thick side and a thin side. Thin side faces wheel.
@@track1219 Nice. I'm definitely going to do that. About the tensioner, you mean the roller? Like the lip on the roller is wider on one side? I ended up replacing it with a steel roller and it works lot better. The plastic ones wore out way too fast.
The 2 chain adjusters that the axle goes through, one on each side. Each one has a bolt and locknut. To adjust tightness of chain. Sorry, I didn’t explain it to well!
@@track1219 Oh yeah I know exactly what you mean. Yup they fat side goes out or that would make it even worse. I did see that but i bet a lot of people would miss it.
You should be able to make the sprocket side spacer smaller? You are just spreading the swing arm and not really changing sprocket to driven sprocket alignment. I would take off 1/8" or better yet have a machine shop take off 1/8".
Remember when you did the uphill race between the bikes? Would be interesting to see what the MB200 does. A heavier 196 bike versus the lighter 200U with a 212. Especially if the 200U still has the 9/60 gearing. In theory the 200U should do the hill quicker with more cc's and less weight.
I think I can take off all I need on the outermost right bushing because there seems to be quite a bit of space between the brake mount bracket and the bracket in swingarm it attaches too. I think they made it too wide.
Plus I think entire wheel is off center to the left. Also the further I can keep sprocket to right the better especially if I want to switch to regular TAV setup.
Question, what is the largest mini bike u have and what’s your thinkin* on it.
Thanks great detailed vid
Thanks. MB200-2 is the biggest.. Needs stronger springs up front or spacers for springs in forks. Other than that it's pretty nice. It's really comfortable to ride too.
Are the sprockets the same thickness?
Both for #420 chain, yup.
..but I didn’t measure them with a caliper or anything. Should be same or very similar though.
The spacer problem ?... you stick a screwdriver through the axle hole to catch the spacer first then with pressure from the screwdriver and spacer will open up the pinch while pushing the tire to adjust to the screwdriver. You're welcome. Also? Any real mini biker knows you're going to have to buy new tires new sprockets new torque converters. It's not a one-and-done thing. But a lot of fun when you're passing motorcycles
ok
Is it mandatory to change the tourqe converter stuff? if im just changing the chain and sprocket my chain just broke so i figured it was time for an upgrade.
Should be fine, I went back to stock front pulley. I’d look into a chain tensioner though if you don’t have one.
the problem with your rear wheel fitment may stem from the stand you are using.
Not enough weight on it to bend anything. It’s just too narrow, or spacers too wide. Probably a little of both.
It’s not grease out of bearings it’s coming off the chain , flinging off high speed ect
I use chain wax.. no fling! That's why it's great stuff.
Does the stock front 10 tooth sprocket do just a good with the rear 60 tooth?
On this bike it probably would, the torque converter works a lot differently than a regular Comet clone TC in my experience.
Bwx any idea how long those spacers are? I have a og mb200 wanting to convert to disc brakes in the rear. Og mb200 only has 2 spacers in the back and I can’t find the 3 spacers for the mb200-2 anywhere
I don't think I ever measured them. I can throw a caliper on them next time I'm in the garage if I can get an accurate measurement while still on the bike.
Also I'm not sure if all the extra spacers will fit on that bike. This bike has a swingarm that might be wider. Not sure.
Hours after I made this comment gokartmasters emailed me saying they just got an order of them in. Thanks for the reply!
@@zombiekill100 Cool that you found them!
@@bwxmoto ya man I’m pumped. I’ve been looking for awhile. I was about to buy a ton of washers and try to get everything sorted then measure the thickness of the washers and have a shop cut me some spacers. And like you said these may not work but it’s closer than what I got lol
Were did you get those rear mirrors ?
Just cheap Amazon mirrors. About $15.
I would have removed the swing arm and used a bottle jack to spread the tubes and not the mounting tabs.
Could have but just tried something with what I had around at the time. I'd rather shave down spacers so it fits rather than try to bend those tubes again anyways though. Hopefully next time i have rear wheel off that will fix it.
I really. We’d to see you step by step put the brake caliper back on. I can’t seem to figure out how to get mine back on after I changed my sprocket .
I’m going to publish a vid today that shows that 👍.
@@bwxmoto I’m doing the exact same mods on my mb200 trail master. Please leave no stone unturned. I’m new and dumb to this mini bike world. Lol
@@truestwarrior23 Yeah but they’re simple. You’ll get it no prob. Hopefully vid is done encoding soon.
@@truestwarrior23 Check it out th-cam.com/video/_OP7e2Or_Ug/w-d-xo.html
Man that looked like a real PITA. I just got my 1st mini bike this week which is a Coleman MB200 since all the trail masters are.out of stock right now and tied up in transit per all the dealers. I'm wondering how this new incoming batch is going to be QC wise. When demand is high QC goes.down the drain. I am okay with a wrench but not nearly as savvy as you or the other big mini bike channels and I'd hate to end up with something that's way over my head.
You'll be fine, trust me. I think one spacer was supposed be be smaller on this bike or something. It's actually highly unusual that something like that happens, and I have 7 bikes now.. And actually the fix is pretty easy if you have a grinder or a file.
I need to file down a spacer, maybe two. It's a pain, but easy. I probably should have done it before wedging it back together but I just wanted to get that step done for the day.
The great thing about these mini bikes is that they are so simple and easy to work on.. most of the time anyways! LOL
Ahh screw it I just ordered the last one Go power sports had left. Hope I get a good one.
@@dankibler4780 Even stock its a good bike. I think main issue id it’s geared too high bit depends on where you ride.
I’m in NE PA and my property is a lot of hills. The RB200 I have now is a 53 tooth rear and can get up them but I can hear and feel the clutch straining. I’m hoping the CVT will be better and already figured on a 53 to 62 tooth rear sprocket at the very least.
@@dankibler4780 9t/ 60t is awesome for hills. 8t/60t even better 👍
Ratchet strap on each side ratchet them apart line up wheel and axle then release
I did think about doing that! But didn't really have a good spot with with sturdy anchor points.
@@bwxmoto your car is a good anchor point a tree 🌲 anything your not going to need that much tension .
looks like thje mb 200 has the same bearings as the coleman ct 200.
For the wheels? Yup I think so. The wheel that GoPowersports sells with the front brake kit has a different size bearing I noticed.
Not sure about the Hurricane that’s basically an MB200-2 with front brake though.
Oh Do You Know Anywhere I Can Order Another MB 200, My Mom Wants One
I think they’re out of stock everywhere now. Might check Facebook marketplace.
Go Power sports put up 10 last night, as of now they are down to 4. They are up to $999.99 with free shipping and no tax if your not in Texas.
I'm running a 54 sprocket with no chain tensioner but I'm also running 11.5 shocks instead of 12
I wonder what happens if you take shocks off and see how tight the chain gets when you let swing-arm travel upwards? People always say they destroy their bearings, I think that’s one reason why.
I think the shorter the better though.. I'd like to find some 10" or maybe 10.5" shocks that have 2" or more of travel if they make such a thing. But also can't be too stiff. I see a lot of those shocks have about twice the spring-rate of these.
I switched to a full tav set up cut the Jack shaft off got the 290 mm 11.5 shock they are soft but better than stock it feels like a cadillac I'm running rk gold chain and had no chain stretch so far and I'm 245 pounds this the second trailmaster I built learned alot from the first build
@@Kevinmcinnis30679 Nice! Are they bigger around than these? I was concerned about the shocks with larger around springs interfering with my 60 tooth. I'm about 200 lbs hopefully to be closer to 180 soon so these should be stiff enough, but I'd like slightly shorter ones and maybe ones with closer to 3" travel, these are only 2". Still better than stock though.
Shocks won't mess with sprocket I'm curious what your top speed will be with your set up you can also go 280mm 11 inch shocks that might work better for you
My mb200 trailmaster have short spacers on it
Shorter than mine? Is it an MB200-2?
