85 Vfr750 Gears Slipping And Grinding - esp 4th.

Hi all. Just read thru this article and it sounds allot like my problem

http://www.vfrdiscussion.com/forum/index.php/topic/72644-4th-gen-clutch-issues/page-6

When i goto 3rd it starts slipping in and out of gear making a grinding noise.. 1,2,6 are OK.. With 1 and 2 perfect.. 4th and 5th seems worst

When the bike idles and i lean it left and. Right the noise changes to a light rattle inside as the bike tilts...

I have a spare motor, will be first time crackinga trans issue in many yrs.

Any ideas?

One mech said sometimes the trans wears into the cover and i should shim it or something.

Do i have to drop motor to split case?

Tx

Also - the clutch seems to work fine, I can change gears really well at the mo - no "late/early" grabbing indicating the plates are still A ok i hope

 

Bent or worn shift fork ??

 

It sure sounds like the shift forks and gears are smoked. No sugar coating the task at hand.
