Hi, my CBR 250R is only 560Km old and the lower part of the chain slider got broken somewhere and came out hanging. I tried pulling out the upper part of it to remove it completly, without removing the mud flap or anything. But I failed, its too tight or fixed to somewhere near the swingarm joint. Can anyone tell me whether replacing the chain slider is a DIY for a beginner (only done an engine oil & oil filter replace by myself yet)? I have read here in this forum that early ageing of this chain slider is due to some chain tightness or wheel alignment issues. But to check all those, I have to take the bike out to the ASC, and for that I have to replace the chain slider. Any suggestions would be helpful.
