GSXR 750 '88 Restoration Part 9

And here we are, at the point which I have to check everything inside the engine.
And since a few people asked me how can one determine what colour the bearings are if you don't have any marks on crankshaft, crankcase of con-rods, I decided to make a video to show how can it be done. Because it can!
Watch this video to find out how can you determine something that seems to be a huge problem!
0:29 What if there's no codes anywhere?
1:10 Con-rod identification
2:35 Crankshaft code identification (for con-rods)
3:54 Crankcase code identification
5:35 Crankshaft code identification (for main joints)
6:58 An alternative way...
10:53 Some gearbox measurements (usually neglected)

Hey Chris just a little info for u the bearing shells r thinner toward the joins they r made on purpose like that to act as an oil reservoir So u can c measuring there is incorrect I didn’t have this info u r sharing from Yamaha so I bought a selection of shells purple White blue black and I Tried various in the different brg bores! As u can c that is a long winded procedure but as I knew what thick the dif coloured shells r I could take educated guess on all the. Mains. I repeated this on the big ends and ended up with Purple every where but am super happy as the oil clearance is all excellent now really good video think u for sharing

Thanks for the info!!! I'll keep that in mind. I thought the were of the same thickness all over. But what you say make sense! Thanks again!

where did you find main and rod bearings? ive been searching for new bearings for my 95 gsxr1100w engine with zero luck.

[@REBUILDLab]

How do you clean the oil routes inside the crankshaft?

[@ChrisSofos]

Good question! I use parts cleaner, followed by a good blow with compressed air.
