Needless to say lots was discovered today.... The good the bad the ugly.....I suppose it's all a part of the process of restoring a bike! Well I think this motor is a donor motor from a junk yard....I'll let the pictures speak for themselves! I will be looking for a new cylinder head.... This should be interesting ....

Didn't take long to remove the engine, and get stuck into tripping it down...I knew from te onset that things wouldnt be pretty .........

Your timing couldn't be better bud! I have one just like it needing TLC about to fall in my lap. Mine is already red and has all of the parts so I've got a head start...which I will need because I haven't laid eyes on this engine, or any thumper guts in 8 years! This is a great way to get re-aquatinted thanks

OW! You got a mess on your hands. Lot's of broken parts.

This would be a good time to sit down and make some decisions.
Knowing the parts availability situation, the cost and the time that
will be needed to attempt a rebuild on that engine, are you better
off proceeding or punting?

When I see cracked heads, broken pistons, broken keepers, etc.,
Red flags and dollar signs go up.

I'm not advocating either way, but now is the time for a decision that
only you can make. How bad do you want this and how much are you
willing to spend to make it happen.

Dogger-
Yes it is indeed decision time!! There are a lot of these bikes wrecking for relatively cheap. I'm yet to clean everything up and give the motor a good look over....
Really sucks that I keep on finding 'dud' bikes.....
At the end of the day this was meant to be a fun/challenging project. I don't mind the time factor. The way I see it, if I can find another head that is usable ( there are a few places to check ) and snap up some bits that are needed, then I'm going to go ahead. There are bound to be a few xr's that aren't as beat up. I've managed to locate most of the pieces so the stuff is out there. Many of the frame bits and ale gone bits are still available as are second hand parts etc. Tomo is my hunting day, if it's looking slim then I guess I'll call it a dead end.

Ps an email will be sent shortly

No doubt.
I hope my rebuild is not that bad or it will get parted

If you part it.....lemmi know

---------- Post added at 04:26 AM ---------- Previous post was at 03:32 AM ----------

Ok all is not lost!! So I've just been reading that the XL 250 head from the 1985-1987 will bolt on...I think ( to be confirmed by the guy I've just email...). He wrote in his thread about the XL 250 head being RED ( this is to my best knowledge the ONLY difference ) and he had to paint it black....
IF this is the case I beliee I may have found a NOS XL 250 which will bolt right on to my XR 250 body....after all the feast of the parts are exactly the same!!

---------- Post added at 04:33 AM ---------- Previous post was at 04:26 AM ----------

To confirm some of my beliefs I stumbled on this YouTube video...yes I know the bike was running BUT the XL bottom fitted the XR top so leads me to think the same would be true with the XL head!!

Ok im finally piecing this all together....this is what is up:

Not a great deal is known about the interchangeability of the XL and XR parts...I've have spent DAYS hunting for info....finally found some stuff.... The 1984-1987 XL 250 R ( note XL 250 R ) used the SAME head as the XR 250 R the XL engine was red WITHOUT a tachometer!!!! This is why the other bits for the head match up ( vales etc etc ) the XL 250 L had a different head and cam setup to accommodate for the tachometer... Here are two pictures to show you what I mean...

This is the cylinder head cover....from the XL250 without the tachometer....the only difference is NO TACHO.


This is the XL250 WITH the TACHO..... AND it's black...


This may or may not make sense to you, but essentially the part numbers are different because of the colour change very simple....so now I can ( if I decide to ) buy a new cylinder head and head cover ( only they will be red )

---------- Post added at 04:56 AM ---------- Previous post was at 04:52 AM ----------

Sigh!!! I think I'll be well versed in XL/XR motors
After all I know they are basically the same...but it's the nitty gritty details that are always interesting

Hello stevo450

All the best with your XR 250 project, I'm looking forward to seeing you bring this one back! Shame even that Honda engine could only take so much, it definitely deserves some TLC.
