Hello guys , I want to share an experience . I wanted to try longer gearing so got a 15 tooth front sprocket , which I found could only be fitted if the case saver was ground a little bigger , which I did but apparently not enough . I have damaged the inside plate of the chain where it has been catching on the case saver as it comes around onto the sprocket , some of the side plates have actually cracked and the brand new chain will have to be replaced . To top it all the 15 - 44 combination is much to long anyway .
