Chain Tensioner - Right Side


Product Description

Right side chain tensioner for the 2 Stroke Shift Kit. Although Sick Bike Parts does not feel that chain tensioners are necessary we give the customers what they want. This right side tensioner may reduce how often you need to adjust your right side chain. However, we strongly recommend you first investigate why you are needing to adjust your chain on a regular basis. This usually indicates an assembly problem. Note, this is designed for use on a standard bike. Some modification will be required for use on a fat tire bike application.

    I have a fat tire mongoose bike with GT5 racing motor . I had to design my own tensioner for the right side. This right side tensioner is to weak spring to small Chain keeps jumping off. So I made my own. Works flawlessly perfect with a heavy duty spring. Never jumps off. If you would like a photo of my tensioner please email me at
    Sick bike parts I would love to show you this tensioner it's far better than what your selling. You could have my tensioner as s a kit real easy. Thank you Glen Shaw Island Motor Bikes.

    As is stated this was used in a fat tire application. It is not designed for that application and required some modification by the customer. It was never intended for use in a fat tire application.

    got the tensioners they say u dont really need them but they make a big difference . glad i got them . the left side bracket i had to drill out a couple holes bigger cause they was off just a hair but was an easy fix. the left side fit perfectly . the engine i had diddnt have one the holes for the left side bracket but thats what a drill is for . the aluminum is easy enough to drill through and hardly no pressure is needed to do so. remember to be careful when drilling as its aluminum. in all i feel they are must have parts it not only helps ur shaft from ware but reinforces ur motor shafts and studys up everything. im more than happy with the jackshaft system and the tensioners .
    the jackshaft 2 kit is a damn good bargain for what u get even tho the kit cost more than the motor i ordered but i have disk front and rear brakes and needed it to keep my disks . another good thing to have is the double brake handle that comes in the kit. makes it much easier i feel . will order again in the future.

    It's a necessity, but it doesn't work that great. If you have the shift kit, you can't have much slack in the chains because it will fall off easily and ruin everything. If you use the engine lift to tighten the chain, the right side of the engine will lower and it will cause your engine to be lopsided. The tensioner is a little bit hard to figure out, even though I am mechanically inclined. It doesn't feel very secure and I'm constantly having to tighten it. I had to get a more powerful spring for it because the stock one wasn't giving enough power to hold the chain in place.

    this chain tensioner is the best thing you can do for your moterized bike nothing but good things to say years ago the chain popped off all the time i mean all the time the cheap freewheel that cost 19 dollars got 1 -2 mm slack on the races of the bearing and the chain popped off even a brand new one the chain tensioner that goes on the seat post it just raises and lowers the rear of the engine well you can only raise it and lower it so far before you bend things this chain tensioner solves a lot of headaches the chain even poped off when i started it not any more you could put guides on it to further reinforce it as in the you tube video "SickBikeParts R.H.S. Chain Tensioner Modification" it looks like its very fail safe thank you sick bike parts
