xr 75 parts

Recommended Posts

Hi i know it's 80-200 area but still i didnt find a better place to ask.

i'm looking where to buy parts for xr 75, now i'm not sure about what year is it, how can i find out? i prefer by engine number because in the frame it's hard to see.

Are the engine parts are the same as the newer xr80?

for now i'm looking for the valves, and i saw somewhere that they all the same, so i want to make sure.

thanks, Amit.

If it's a rider you're far better off to build a more XR80/100 engine (bolts right into your frame) than to try and scavenge parts for your XR75 mill. If it's a restoration... You're call.

For a 1977-78 XR75, pretty much everything will work from and XR80. For a 1973-1976XR75, totally different.

Thanks for the replay.

now my problem is that i dont know really what year is it.

is there any way to find out by looking on the engine? what is the big difference between the old engine to the new?

thanks again

The valve covers are totally different. That's the quickest way to tell. Everything is differnt, piston, head, cam, cases, etc.

The one that i have is with the cooling fin,

So the cover with the cooling fin is for the new engine?

i saw in ebay one with fin and it say that it's for 76 too, so he have a mistake?

I have the cylinder off also so i can look at the piston too, what is the different in the pistons?

Thanks again
