HI! Sorry for answering late... Marry Chistmas and Happy New Year! Dont khow the strenge of spring, just use for measuring peaces of broken spring, and pick something same. Still have "very very slow" leakage, but im OK with that

I have no VIN plate too, because my GSXR is JDM.

Hi all! I think much of us faced this problem... Can you advise so methods of solving this damage? Cutting off part of pipe, or trying to unscrew and straighten with heating?

Amazing bike!!!

I probably got it. If servise limit of upper case clearance is OK, so its OK. If servise limit is exceeds, so i shouid choose thrust bearings for lower case.... I think so.

Upper part of crankcase dont have 1-2 mm gap. Its about 0.15 mm.. But also lower par of crankase have them - 1.5-2 mm. I understand that they should be there, maybe tell me how to choose them? And maybe you know the thickness of these plate bearings? Maybe some thrust bearing selection table?

Good evening all! Mates, have one question about plate thrusts for crankshaft. Making some big order for engine overhauling, and trying not to forget any parts. So, question is - do i need this plate thrusts, if they were not there initially? Crankshaft thrust clearance is OK. I doubt it, because in some manual (I don't remember which one) I read "... if they were installed initially ...". And also they illustrated on partlist (pos.12, 13). GSXR 750 1986. Thank you in advance!!!

Already

Please tell me, if i have code "A" on crankcase, which indicates size 35,000-35,008. so when i will be choosing bearing size, which number should I take into account? 35,000 or 35,008 or average between them?

Thanks!!! Of course! This conrods (all 4) are already were there, before i started overhauling. I have drove about 2000 km on this conrods/crankshaft. This is a puzzle that the previous owner left me)) So, will do my best!

Glad to have at least this

And more some codes. This 27A is evrywhere on engine)

I'm trying to figure out if these conrods can be kept. Because, just looking at the picture, they look like from 90. And if the crankshaft for 86 and 90 is the same, then it means that i can install these?

Yes, i measured 18/34. 90s 750 engines are long or short stroke? Could it be, that this conrods from 90/750?
