thanks fish, if these can be verified ?, ( as in..some folks check them maybe ? ), i'll make this a sticky .

 

[fishfiles]

I have the TRX300FW and A engine serial number breaks , but only from 88 up to around 96 or so , will try and get them up there also

I had someone ask me the serial number on the 07 500ES motor I got on that parts bike a while back.

I've never noticed a SN on an engine. Where is it usually located?

 

[fishfiles]

Jeep , on a 300 it is on the right side top of the case in a square box , same on a TRX250A , the 450 is on the upper , left rear crankcase , can't see with the covers on , I have a 500 in the yard of a friends right now and you can see in the pic , you can't see nothing , would guess it is the same as the 450


here is a chart of the TRX450 engine serial numbers

 

[Kjlowe34]

I have a TB05E
2142250

what could that be? I don’t see it on the list

[Goober]

You’re just looking for the model number TB05E-21
The 4225 you’re seeing is the case number
