How to identify my motor ?

PostAuthor: IronGears » Tue Jan 09, 2018 6:51 pm

Happy New Year everyone !!

This is my first post here as I have recently purchased an XV750. I will be picking up the bike in a few weeks.

The current owner had purchased this bike as a donor for parts but didn't end up using parts out of it. So it was stored for short period. I managed to get it for a very decent price. The current owner has not heard or seen it running but claims the engine has compression.

So the frame is an XV750, but the motor is an XV1000. I have searched the web and the forum to get an idea on how to identify the motor but had no luck. The reason I am trying to identify the motor is that I need to get a starter motor to get it running, along with some other bits and pieces to pass the safety check.

So the question is, is there a way to identify the size of the motor by its appearance or is there another way? Are all XV starter motors compatible or interchangeable with the XV series motors?

The bike needs a bit of TLC, but my plans are to convert it to a Tracker style bike by the end of this year. But I would like to have it running first.

I hope I haven't missed any crucial info.

Looks like the engine number starts with 1TE, if so, it would appear to be a 1992 XV1100 Engine. All early 750/920 starters were the bendix type. Yours uses the later model starter for the 1000 and 1100. Those were all the same until the end of production in 1999. I can't see if the solenoid and the drive lever assembly is there from the pics, but here is a link to the OEM starter in the US. You should be able to find these locally on Ebay. https://www.partzilla.com/product/yamah ... dc16110422
This link shows the part numbers for the solenoid, drive lever assembly you will need. https://www.partzilla.com/catalog/yamah ... ter-clutch
Other part numbers can be determined from this site....

That engine is definitely newer than the 1000. The capacity is cast into the bottom of the front cylinder, facing forward.

If you plan to run the stock air filter of the 750, you need to either run a long hose over the engine from the front cam cover, or swap the front and rear covers. If you swap - which I did - you also need to take the splash cover attached to the end of the front cam and move to the rear cam.
