Sthus Black Spring Loaded Chain Tensioner For 49cc 66cc 80cc Engine Motorized Bike 2 Stroke Engine

Review, important need to know, installation guide br>br>However, I wish the spring had more tension and the screws/bolts weren't made of aluminum because one of them snapped on me. br>br>Also, for those with higher cc engines or torque, make sure your chain is tight before installation because when you engage your clutch even slowly at high speeds, the bottom of the chain fully pulls on the tension wheel, and if the chain is not tight enough, it will cause slack in the upper part of the chain, causing your chain to lock up in your housing, bringing your tires to a halt or, if you're lucky, breaking your chain There is no need to lift the lid. Just click the pull-down menu to click on Step 1. Next, place the spring into the mounting plate where the 2 small holes can be (Top one in tension) o.

You won't believe how much of a difference it makes if you don't have one and are still using the stock idler/tensioner. This is the ONLY upgrade you should make if you don't do anything else!.

They're simple to install, but they're thin and flimsy (you can bend them by hand), and they don't seem to provide enough tension on the chain, so I drilled additional holes above the pre-drilled holes. For a little more chain tension, I drilled holes for the spring. The bearings are better than your typical cheap white/yellow roller bearings, and I've only put about 100 miles on this tensioner and had to adjust it every other ride. Replace the lock nut on the pivot bolt with a nylon nut after just 30 miles of easy riding. There should also be a bearing on the pivot to prevent play in the tensioner arm. However, because of the thin metal used and other factors, I would not recommend it.

UPDATE: For the past two months, I've been using this tensioner. It's still in good working order and isn't broken. To provide more tension, I drilled a second hole higher up. Excellent work!! br>br>Thus far, everything has gone well. It was only a few hours ago that I installed it. I was using the tensioner that came with the kit, but it continued to move, causing the chain to jump. I put it on and drove her around the block, and the chain worked perfectly. The pedals hitting the bolt heads is not a problem for me. On first inspection, it appears to be sturdy and well-made.

It will work with almost any chain you can throw at it, but it will make a lot of noise, so get the one with the sprocket.

great. This is a great set. Pulley is a little wider than it used to be. After the installation, I was able to touch the tire and/or engine mount. I just needed the extra centimeter of clearance, so I put the pulley in another hole and bent the arm slightly. It turned out nicely and the lines are still straight. It's far superior to the one from the factory. All of the assembly is also covered by the chain guard. You must reshape it if it is to fit. So I did. I used pliers, a hammer, and a table vice, and everything turned out perfectly. After everything was put together, I drove a few miles to test it out. The pivot bolt had backed out of the arm, which I had noticed. Recommend that everyone double-check their bolts. To aid in the process, I placed two nuts. In order to attach the chain guard, I needed to purchase a longer bolt than the one that came with it.

It's a good idea, but it could be better; for example, the spring is too weak, the bolts enclosed are too short, and there isn't enough room for the chain guard. 0The best thing to do is get the chain tight enough that you don't need a chain tension device; I got mine tight enough that I didn't need one, and it runs great with no slapping, jerking, or jam ups.
