Those chain tensioners are amongst some of the best things you can do to these bikes, and they make a few different styles but man these bikes have a lot of chain pop issues especially bikes with rear shocks, when I installed a chain tensioner it changed everything, took me a bit to find the perfect chain adjustment for it but when I did it was a complete game changer.
Yup I haven’t had one chain problem since that tensioner installation. And the 12” shocks are too long really which makes it worse. My brother even rode it for hours in the woods and stuff and he’s bigger than me - weighed over 200 lbs at the time.
Thanks for your videos they're very informative. I realize this is a year-old video but wondering if the spring you use on this chain tensioner worked out I've done mine exactly as you have done and mine seems to be too tight strangely enough. Thanks again for the great videos
Hey thanks. Yeah I ended up drilling a hole higher up on the chain tensioner arm and that helps a lot. It was too tight how I had it. I’ll have to see what’s in this video but I ended up using a metal roller and that worked way better too. But yeah, if you drill a hole higher up on the arm, it takes a lot of pressure off of the chain, but it still works great. And actually I haven’t touched it since and I’ve ridden it a lot and it just works. It’s probably time for me to take it apart and re-grease up the bearings in there and see how it’s wearing and stuff. I’ll probably do an update video on this bike soon.
LOL I was making a riding vid today and was taking a vid with my phone and your comment notification popped up. Pretty funny, I captured it on gopro. I'll give you a shout out. 😆✌
You've demonstrated exactly what I need to do on my new MB200-2 mini bike. Where did you purchase the 1/2" od rod and which spring are you using? Great job and fun toy!
Thanks! Yeah tons of fun. I actually got that on ebay I think. Kind of expensive there. Maybe some local welding or metal supply shop would be cheaper.
Can I suggest that you drill a second hole on the adjuster arm and just run the spring over the bar and back down. It will double your tension. I think you want it stiffer so when it’s a quicker depression of the shock the adjuster reacts faster.
Good idea! Yeah I’ll try it see what happens. 👍 It’s crazy how loud that thing is though. 😬. But good news is chain stays put when riding. So it is functional at least but at higher speed there’s s a pattern of loosening and tightening that I can hear. Maybe some more tension would help that. 🤷♂️
Good explanation of what happens with the chain when you Change the geometry with larger shocks. I’m assuming that if you stay with the stock shocks there will be less of a need for a tensioner? Probably something I will still do eventually but I don’t plan to change the shocks for awhile.
Thanks Yeah I had problems with the stock setup though. It's worse with longer shocks though. I think ideally you'd want same or just a little longer length shock than stock but with more travel. These are 12", I'd rather have 11" shocks and they make them but they are a lot stiffer. I rode it yesterday and these feel pretty good to me and I'm about 200 lbs.
@@bwxmoto I am 6'3" and 205 so I might need to address shocks sooner then later. It would be nice to see Go Power Sports start supplying or making things like the chain tensioner kits. My bike shows up Friday and then fun begins.
@@dankibler4780 Nice! It's a good bike even stock.. but I like the lower gearing, but I want the 8 tooth for more low end torque still. Changes so far have been good though!
Gopowersports 12” shock upgrade. Not sure I would recommend them though. I think I’d try to find some shorter ones, maybe 11” or 10.5, and they have no or very little damping so they’re bouncy. Still way better than stock shocks though, but I’d like some with more damping.
I went to Lowe's and found a few that looked right and a package of a 5 more and found one that worked. I'd buy a few and you should be able to get one to work. I think it was about 4 in long when coiled up but a shorter one could work too.
Thanks for sub! This is all experimental for me though.. But, I did ride it a couple times since this vid and I can say it does work! No chain crunching on the driver pulley and it doesn't fall off, also the shocks are great. Way way way better than stock. Have not felt it bottoming out at all and there's noticeably more travel and ground clearance. But I think I need stronger chain tensioner spring or hook it up so it's stretched out more. Also this chain tensioner makes more noise than I was expecting. Not sure if normal. I think I need the 8 tooth front sprocket though, and stage one. It doesn't really compare to a stage one Predator with 8t/ 60 tooth like on my EX and BT but it still climbs 100 times better than stock. Haven't done full speed GPS down hill test but did have it up to 41 MPH on flat ground. Runs good!
@@bwxmoto yeah I’m stuck in limbo now waiting for my parts to arrive to build the tensioner. I’m also doing a stage one with the mb200 super header as well. You and I are building the exact same bike .
@@truestwarrior23 Yeah that sucks! I waiting for my chain tensioner parts for a week or so.. Then it got cold again, then other stuff got in the way. Took longer than it should have to get this far. LOL But I also have stage one planned and front brake too! And more stuff! 😁🤘
Oh maybe that chain tensioner bracket is reversed. That has a thick side and a thinner side. Can't remember if that would cause issues like that or not. I'd have to go look at bike but it might.
The four bolts that hold the brake disc to the wheel hub. I have the spacers on the same way they came off, exactly like yours. I did get a new wheel put on, would flipping the wheel around make a difference
Yeah definitely more low end grunt for climbing and acceleration. It also gives your TC belt a mechanical advantage and they last way longer. I have burnt up belts in one ride trying to go slow up hills in the woods before with even a 9t front and stock rear sprocket.. Lower final drive gear ratio allows you to crawl slower without belt burning up and climb steeper hills basically. Check my vid coming out tomorrow 👍😎
@@DC-gh9yv Thanks! Yup I like to run the bikes stock for a while at least to gauge what the mods do. For steep hills though the stock gearing is way too long but ok for moderately steep hills or flat ground.. Stock setup really flies going down hill though!
@@truestwarrior23 There’s a bunch of different sellers for those. Some of them on Amazon you can see look identical and they have different dates. The ones that ship sooner seems like there are a couple bucks more

Even with the stock shock the tensioner is a good investment.
I think so!
If you can move your jack shaft to the swing arm pivot your chain tension will remain constant.
Yeah but you can't very easily do that on this bike. You'd have to re-design and rebuild the frame.

If I wanna ride tomorrow I’m gonna have to go back the stock sprocket .

Did you have a problem with the brake disc bolt head hitting the back side of the brake caliper? I can’t figure it out. The wheel will not spin
No but I think the axle spacers might be on wrong if that happens. Or could be something else I guess. Trying to think what else might cause that. 🤔
Oh maybe that chain tensioner bracket is reversed. That has a thick side and a thinner side. Can't remember if that would cause issues like that or not. I'd have to go look at bike but it might.
Actually after re-reading your comment I'm not sure which bolt head you mean.
The four bolts that hold the brake disc to the wheel hub. I have the spacers on the same way they came off, exactly like yours. I did get a new wheel put on, would flipping the wheel around make a difference
@@190dopey Maybe but I wonder if the wheel is identical to stock or maybe it’s different enough to cause problems?
Just ordered 2 of these bikes 🤙 what's the advantage to the bigger sprocket,just more low end torque?
Yeah definitely more low end grunt for climbing and acceleration. It also gives your TC belt a mechanical advantage and they last way longer. I have burnt up belts in one ride trying to go slow up hills in the woods before with even a 9t front and stock rear sprocket..
