Who a good identifier at motor years

Recommended Posts

Bought a 97 rm 125, partial engine installed. Ordered a manual and some of the water pump pics in manual are different than what I have. What is a identifier that this is actually a 97 motor.

The prefix of the engine serial number will tell you what generation (year) your engine is.  In your case your looking for J115.

Sorry, I just realized that I posted numbers for the 250's and not the 125's.  This should cover it:

Been there.  At that point your left with spending some serious time on the net looking up part diagram views of what your engine should be verses what it is.  I don't have that much 125 experience but do you have any clutch & sprocket side pictures of the assembled engine?

I'm thinking/hoping this manual is a different year! My crank bearings and seals showed up just now and are proper fit based on ordering for a 97. Of course they may cover many years I guess.

Crank just got rebuilt, he said the rod was the same as a 97, probably the same deal, covers many years. Few pics of right case, maybe something will jump out at someone

Biggest worry being parts of course. Rolling chassis for sure a 97 but ordered a bunch of engine parts that I don't wanna send back or tear up and can't send back. How compatible is the 95-97 engine.

def. not gonna matter. fuel air charge is heading into crankcase at that point any way, if it leaked at all there, which I dont believe it will, it will leak fuel/air charge into crankcase.

Also, I always lightly sand the gouges out of the crankcase around where crank sits, if my case has any gouges.. In your pic it looks like yours may. It may not matter but thats how I was taught so thats how I do it.
