Hi All, I would like your opinion please. I am rebuilding my Bandit 1200 engine. It has done 80000 miles and 5th gear went tits up. I have got the bits to sort this, my problem/query is do I do the big ends and main bearings whilst the engine is in bits as a precautionary measure. There were no knocks rumbles or strange noises prior to the strip. I have had a look at the main bearings and there is very little in the way of marks just some shiny wear patches, the journals look fine too.
