azxvz1284 Posted October 23, 2014 Share #1 Posted October 23, 2014 Is the left side transmission cover the same part for both the XVZ12 (1983-1985)and the XVZ13 (1986-1993) or are does each motor have a different-sized cover?

Wizard765 Posted October 23, 2014 Share #2 Posted October 23, 2014 I believe they are the same.. I know the stator, middle gear and water pump are because I've used them and I think the tranny cover is also the same Link to comment Share on other sites More sharing options...
yamagrl Posted October 23, 2014 Share #3 Posted October 23, 2014 84-93 Same part number. 83 slight variation. I noticed several on ebay Item 15 here http://www.partzilla.com/parts/search/Yamaha/Motorcycle/1984/XVZ12DL/CRANKCASE+COVER/parts.html Click on 15 and it will also list which bikes it fits. Item 20 is the gasket for 83-91. Link to comment Share on other sites More sharing options...
dingy Posted October 23, 2014 Share #4 Posted October 23, 2014 The 83-85 is about 1/2" narrower than the 86-93 version. The motor block has no change in this area over the years. Difference is due to changed stack-up height of the clutch pack when changed from 6 helical springs to the bevel spring. You can put a 86-93 clutch cover on the 83-85 motor/clutch combo. But not the other way. I discovered this when upgrading clutch about 4 years ago. Gary Link to comment Share on other sites More sharing options...
yamagrl Posted October 24, 2014 Share #5 Posted October 24, 2014 I think we are we talking about the middle gear cover on the left. Link to comment Share on other sites More sharing options...
dingy Posted October 24, 2014 Share #6 Posted October 24, 2014 Crap, I need to work on reading comprehension. All side covers, except clutch, are interchangeable from 83-93. Gary Link to comment Share on other sites More sharing options...
azxvz1284 Posted November 9, 2014 Author Share #7 Posted November 9, 2014 Hello Gary, Can the stator cover/housing be swapped between the 1984 XVZ 1200aand the 1988 XVZ 1300?

Prairiehammer Posted November 9, 2014 Share #8 Posted November 9, 2014 Richard, As Gary said, all the engine case covers are interchangeable with the exception of the clutch cover. Link to comment Share on other sites More sharing options...
azxvz1284 Posted November 9, 2014 Author Share #9 Posted November 9, 2014 Is the Stator Housing the same for the 1984 and 1988 VR's and therefore can be transferred between the two bikes?
