Rear drive available...would you?

[jasonm.]

Correct me if I am wrong. ..But I believe you can put a 1300 1st gen rear drive unit on a 1200. So, IF YOU had a 1300 1st gen. and had a chance on buying low mileage 1200 rear w/shaft and swing arm complete at a really cheap price , that you personally inspected . Would you buy it for your aging 1300 to keep as a spare???

If you do put an MKI drive in an MKII, you must also use the MKI drive shaft. They are different lengths.

 

MKII is bottom shaft in picture.

Which drive shaft is longer 1300? :canada:

[dingy]

The 1200 (MKI) is shorter than the 1300 (MKII)

 

Also MKI does not have seal like MKII does.

 

Had wrong picture in my previous post, fixed now.

I believe for the 1300 you would be better off picking up a second gen rear drive for a spare. If I am not mistaken the only difference is the the second gen has an extra hole for a sensor which you simply plug. Other than that I am pretty sure they are the same.

Thanks for this info on the shafts. The one I can get is complete w/swingarm and shaft. I took a quick look at it. The guy said. "take it home and inspect it and let me know"...I did not take it right then. BUT wanted to get a reply from you guys on your thoughts. ALSO, MiCarl said the 2nd gen. rear, ended up placing the his 1st gen rear wheel 1/4" to the left. Which was shown by the axle sticking out a 1/4" to the left more than before. The exact reason I do not know. Almost as if he left out a washer on the axle. Which I dooubt he did. I did check the Yamaha site and there is a pressed in spacer that has a different part # than the 1st gen 1300. Has anyone other than MiCarl used a 2nd gen rear on a 1st gen...???

Vmax is another option. Seems to be a LOT more Vmax pumpkins on

Ebay than MkII's. I got one from a supposed 12Kmi 85 for $100 plus $30 shipping. It was clean enough to believe the mileage. Bolts right in. Use your MKII driveshaft, no need to swap swing arm. I didn't note any offset difference. Axle ended up at same place. I would assume if there was an offset difference the axle would have ended up in a different position laterally.

 

Bike really likes the 10% higher revs. Zero effect on gas mileage even cruising at 5K RPM @ 80MPH

In a word No.The 1200 final drive as a complete unite is a lot more maintenance.If you dont grease the shaft were it connects to the final drive it will wear and you will lose the shaft.The zerk is useless. There are no longer any 1200 shafts available.If you want fresh gears then transfer the 1200 gears to the 1300 pumpkin.Not any more work then swapping out the whole rear end.

AS it is, I always remove the pumkin to grease the Ujoint splines at tire changing time. So also greasing the "other end" is not a biggie. Vmax is always an option. But I like the lower RPMs the stock Venture turns. But didn't someone say(sell) here you needed a shim/spacer for the Vmax rear ?

Swap just the gears? you make that sound easy. I have torn thru engines. I am not a novice on such things. But rear drive gear swaps require seals and shimmiing. Which I have done before. Just trying for the simplest replacement in very good condition...as close to stock as possible.
