Need help what year is my Honda CR250


Recommended Posts

Does the cylinder have a deep gouge where a circlip failed and/or wrist pin slid out?

 

With the damage seen on the cylinder head you can also suspect bottom end problems, bits of bearing material making their way up the transfer ports.

Once the cylinder is removed, checking the connecting rod for up/down play and a visual inspection should tell you more.

 

Quick observation but both are safety considerations,

-the front brake line is routed incorrectly, it should pass behind the lower tube (less prone to damage)

-with no front number plate the brake line also risks snagging on the triple clamps at full fork compression.

The 97 Cr250r has two shock connecting rod links, where the 98 and 99 models have a one piece design.  This is one way of differentiating a 97 from a 98 and 99.

All three 97, 98, 99 have a single radiator and side panels that tie into the radiator shrouds.

92-01 cases interchange as well as cylinders and most other parts.

There are minor differences, but most parts will interchange ok.

There are however some parts that you need to watch out for. 
The 96 CR250 has a domed piston and 97 CR250R has a flat top piston.  The heads are obviously different to accommodate piston dome shape.

I don’t seem to have actual pictures of the links that I mentioned, but here is the microfiche pictures.

As you can see from these snapshots I grabbed from some microfiche, the links are completely different and so are the frames.  I’ve circled the point on the frame where the links attach.

The 97 frames have one large tab on the frame for attaching the two links.

The 98-99 frames have two tabs that allow the one piece design to fit between as its attached.

As a side note, the 98-99 models don’t have a lowering link option, but I was able to adapt a 2000 lowering link to fit.  The attached actual picture is of an adapted link fitting on a 99.  If interested, ask me how.

I can't seem to find the engine number but the serial number 10th digit is a 'V' which I've heard is a 97'.

The stator cover with the Honda logo next to the front sprocket guard is plastic. Anyone have a picture of the 97, 98 and 99 shock connecting rod links?

Anyone that sells Honda OEM parts does. Look at the schematic.

Is the head repairable?

To answer your question, “Yes its repairable.”  
Is your head usable as it is, “Yes it is usable.”

Now to better answer the question.  The head is repairable if you know of a reputable shop that can re-cut the same contour of the combustion chamber and deck the mating surface along with it.  All while making sure you don’t change the cc’s volume of the head.

Then at that cost why not just buy a new one for ~$80.

If your just looking to get riding again, you can get by just cleaning up that head a little, by lightly polishing the high points in the combustion chamber to prevent hot spots.  Then on a sheet of glass and some fine grit sand paper lightly surface the head to check for warping.  Note: be careful not to push too hard while doing this so you don’t angle the surface.

Is doing this the right way?  No!  However when funds are tight, it works.

Good luck.
