Hello everyone I have still been working on my predator 212 swapped yl2. Unfortunately the chain keeps coming off just about every time I ride it. I cant figure out why this is so I was hoping maybe someone here could give me some ideas. I started by checking to make sure it had nothing to do with the chain tension or chain and sprocket wear. I have replaced the chain recently and checked for any issues like loose links or seized links and it is all good. i have not replaced the sprocket but it seems to be in working condition still. This didnt stop the chain from coming off though. I also checked alignment between front and rear sprockets and it was very straight.
My next idea was to create this tensioner but it actually caused the chain to derail more so I scrapped this very quickly
Next thing i tried was two tensioners right above each other so that there wasnt any uneven force on the chain this was alot better but only about as good as it was with no tensioners it also caused the top end of the chain to wobble where it used to only be the bottom end. this seems to only happen on clutch engage and disengage but its still causing chain derailing somehow.
This final one is the best i could get of my chain alignment just to show its straight. With the tensioners I was able to run it alot looser as you can see in the photo but the looseness also caused that chain wobble which seems to either happen on clutch engage or just from the engine vibrating. I also noticed that the engine shakes pretty violently under full throttle but it is secured well so Im not sure whats causing it or if it is the cause of my chain issue.
So what i would like to know is does anyone have any suggestions to help the chain stay on more consistently? Also do your guys predators shake like crazy at full throttle? I wish I could get a video but the only time it happens is when I cant be holding a camera.
Quick edit forgot to mention that the overall length of the chain is 67 inches and the slack measurement I calculated was .2 inches of slack this is far too tight and I run it at 1 inch about instead.
