Also its time for a chain and sprocket there buddy
The teeth on the front sprocket look pretty bad in the picture. If the rear is anywhere near that worn i would replace everything. The chain your just supposed to replace when you do the sprockets. The chain could break if you let it go too long i suppose, but from the looks of it you will shear the sprockets first. You also don't have a case saver nor chain guard on there, so it would suck to find out the hard waywhy do i need a new chain and sprocket?? what will happen if i don't get one do u think this chain is going to break ..??? i just oiled it today .. if uv time look at my recent post about the jets in the carb and see what u think..??
