hi everyone! hope you all are having a great friday!
i made a engine mounted chain tensioner that goes on the outside case unlike a traditional one.
heres how to do it. (please note, this will not work with all bike engines etc. please do this at your own risk)
tool and materials
1.drill with pilot bit, 5/64 bit and a 7/64 bit
2. grinder
3. longer bolt ( if found one laying in my garage so i used that)
4. 1/8 steel, and 1/16th steel (i used the 1/16 for my cover because my clearances are tight. i would recommend using 1/8th steel if you have enough clearance)
5. spring (i used a old governor spring, but i recommend you spend the 2$ on a spring)
6. the old chain tensoner that came with your engine.
7. ratchet with 14mm socket and a adjustable wrench.
so first thing you need to do is cut the 1/16 steel into a rectangle (3 and 1/4in by 2 and 7/8in) then you drill the 2 holes in the plate to match the top 2 screws on the clutch plate with the 5/64 drill bit. then replace the top left bolt with the extended bolt
BE CAREFUL ON THIS STEP.
drill a 7/64 hole where you want the swing arm to go. (i would move it up to avoid it hitting the crank arm)
cut a 45 in the lower part so you can gain access to the lower left bolt. (optional, but i did it anyway)
next we make the swing arm , cut a 4in piece of 1/8th steel, then drill 2 holes with the 7/64 drill bit, one on the edge of the steel, the other about 1/4in away from the edge.
then you grind it down until it swings freely. ( you can see what it is supposed to look like)
after that you need to put the swing arm bolt facing outward, YOU PUT THE WASHERS IN THIS ORDER
bolt head, washer, plate, washer,
then adjust the swing arm so it had no play, but swings freely, then interlock both bolts.
then add your pulley on the other side like you would normally.
drill 3 small holes with the pilot bit in the swing arm for the spring. then drill a small hole in the airfilter of your bike (you can mount the spring on the engine, but this was easier for me). and
BAM! you have a engine mounted chain tensioner
(you may also need to bend the plate so the swing arm is aligned with the chain, i had to do that)
