175-83 Head

Hello
Is the 125-83 head strictly the same that 175-83 head ?
If not , what is the 175 part number ? Thanks

Hi Michel;
Here is the 83 XC175 parts list:

Thanks. So the 125 head is different from the 175 head.

Yes it is.

For Motomwo. Here's my 360 or 390 ae bottom end motor.

Michel,
That is a 76 360 auto lots of parts will interchange with the 390 auto.

Marty, That tag says 2052 WTH!! All the shapes of the motor say auto? 2052 is a WR?

The numbers are 2052-1243
2052 must be 360 wr.
2053 must be 360 AE.
Sometimes the numbers are funny.

I think someone must had installed a 360WR motor ID tag onto the 360 auto motor. Maybe the factory made a mistake and installed wrong ID tag. That is absolutely a 360auto motor. Could be a 76 or 77.

Marty

Can this 360 AE motor be installed in a 80 + frame ? or only in a 76-78 frame ?

You can install it in a 76-78 frame. It will bolt right in. Here is one of my riders. It is a 360 auto motor in a 78 frame. I have not personally tried installing in a 1980 frame.

Beautiful country Marty, What the hell is that pipe!!

Yep, lots of great single-track trails. I am lucky to live here in northeastern Oregon. The pipe is a 78 390amx pipe shortened on the vertical section of the chamber tuned to the 360 porting and has a Malcom Smith spark arrestor in tail end. I have since the picture was taken I have installed the 78 green amx aluminum tank and a 79 seat to close the gap between the seat and tank. Super fun bike to ride.

I asked about the frame , because several years ago a member of CH send these pics to explain the short tab and long tab !
I ride only 80-85 frame.

I remember that conversation about the short tab/ long tab 78 frames. For the 360 auto or 390 auto motor you would want the short tab frame. They were used on the 78 125CR and 390 autos. Also the neck bearings were ball bearings, not taper roller bearings. I am sure you could put the auto motor into the 78 long tab frame but not sure which front mounts you would use. Maybe the 420 auto front motor mounts?
