Rim identifaction YZ 125 X

The front wheel pictured below was remove from a YZ125x. It does not have the correct prefix, or does it?
These types of discrepancy's are common, manufactures have all sorts of supply challanges.
Did these bikes come from the factory like this, who knows.
This type of information would only be know by the purchasing officer of the time.

Below photo a pair of DID rims removed
from a yz 125x.

Note the the prefix 1G8R .
The same rim is also found on the 125D.

Rear suspension.

The YZ 125 X has a longer momo shock than a 125 C . The rear swing arm is also different. There is a 30mm difference with the YZ 125 X being longer. Other changes are a chain tensioner and a different chain guide. The chain adjusters are also new for the 125x.
All chain rollers and pivot bolts are the same as a 125C.

Engine paint.

The engine must be painted in a semi gloss paint. This engine will be painted in two pack, just as it was 30 years ago. I am yet to do some experimenting with two pack flat black's on engines. I will post information once I have worked it out.

Engine preparation.

The engine components must be stripped clean and checked for any cracks and misalignments.
Also damage to any sealing surfaces must be corrected now.

Make sure all threads are functioning correctly.
Check engine mounting holes are not elongated.
All seal seats must be undamaged.
