Well the 86 trx motors and the 85 atc motors are the same thing. Should be nothing to worry about. All liquid cooled 250r motors can fit in any year 250r frame trx and atc.

No, something is different, the piston is coming up to far.

Not sure of the Year of the engine.. Honda is no help. I called 4 dealers.... waste of time..

Someone must have a book with the serial number for the engine.

I have the serial numbers for TRX250 for 86 to 89....

I Brought it to a shop and they were confused....

Please Help.....Thanks

I think you need a spacer plate. It sounds like you have an 87-89 long rod and an 86 piston in it. That would make the piston come up too far. If you look around there is all the info you need, or wait till wilkin's or beerock see's this thread, they know more than I. One thing I do know is that the numbers on the engine won't tell you anything. You have to check the numbers on the piston and rod. I have seen a thread not too long ago that compleatley explained everything with the numbers for the pistons and rods from different years. I'll try to find it.

The post by dave83 has the numbers for the piston and rods, that should help.

If your shop was confused then I think you need to find a new shop to take it to. Less than 5 mins of looking on here and those 2 links should be all you need. Mechanic HA! lol

Most dealers don't want to take the time to look info like this up for you, and every one of them should have the book required to do this. You are in luck, since I have the book. The motor is out of an 86 ATC. The TB06E means its out of an ATC, the 2509951 is the sequence number and tells me it's an 86. If the number began with 24 it would be an 85.

For future reference
86 TRX TE12E-1000001
87 TRX TE12E-8000001
88 TRX TE06E-8100001
89 TRX TE06E-8200001

These are all the beginning sequence numbers starting with the first motor built each year.

whats up with the piston stickin out of the cylinder? did you just rebuild this motor or what? sounds like the motor had a spacer plate and you bought the wrong year piston?

you cant go by the id # on the motor who knows if the motor had a 87-89 crank in it when you got it. just because its a 86 things can get misleading.

stop bringin your bikes to the shops in your area, none of them know crap about the 250r.If they do work on it and do something wrong they wont back it up theyll just say something else broke, since the boike is so old. dude just call you got a 250r mechanic a phone call away...
