125-200cc 2012 CR125 needs a crank. Options?

After 57 hours of wide open MX my sons CR needs a crank. What are my options? Haven't found any aftermarket crank assemblies on line. Help!

the big end rod bearing? main bearings? a rod kit or new mains would be easier than a whole crank..most rod kits come with the lower pin..just have a shop install the rod

google Vince at "Mr. Crankshaft".

Good work quick turnaround.

About $150 for a rebuild.

Time for a 177!

My crank lasted 41 hours so don't feel too bad. I rebuilt it with a Pro-X rod kit that I got on Amazon, of all places, for about $75 shipped. My local crank guy pressed and trued it for me for $25. Others here gave it a thumbs up, and it seems as good as stock. I actually suspect it is better than stock, being a Japanese part. If the webs are damaged you will need a new OEM crank, I don't believe there is any other option.

Pro-x part# 03.6217

I typed it into amazon and boom it showed up.

My reeds were also shot and breaking up. The $28 OEM crank seal stung the most, though.

I've got 1.2 hours on the new crank and it is smooth and runs great.

I like your thinking! (177) Budget just will not allow it right now..

bit late to the thread guys

does anyone know what feeler gauges i should use to check my wr 125 2003 oem crank, no up and down play but seems to have a decent amount of side to side. the old husky manuals aren't really illustrated well, i cannot seem to find anything showing how to measure big rod clearance.

cheers

Not an accurate measurement(or particularly helpful I guess) but a bit of sideways movement is normal(1-2mm?). I've never actually measured either my 165 or 300 for sideways play! Up & down=bad

I ordered the "kit" from Halls Husqvarna in Springfield - surprisingly economical and the entire assembly arrived in no-time. Since the thing was down, I took the opportunity to send the 144 to Pro Circuit for the head milling and porting, added the Pro Circuit pipe and silencer, sent the power valves to Wally, and threw in the JD Jetting kit. Can't even begin to describe the difference.

To me it seemed more than 2mm, new piston, ring, bearing and it seems to score up the front of the cylinder more than anywhere else.
