Need help fixing my sumo - June 15, 2010, 11:19 AM

Posted this in my intro, looking for some help if possible.

I'm looking for someone that can put a new rod on my crank. I found a guy in baltimore that can do the work, as well as some shop in kentucky (mrcrankshaft.com). They both seem to have reasonable rates, but I'd like to keep it local.

From my limited mechanical knowlegde, apparently some sort of pressing device is needed to do the job. The two shops that I have talked with have told me $75 and $50 per hour, which I think is a fair price for both. Obviously I would like to try and keep the cost down as much as possible because the rebuild looks like it will cost me $600-$700 as it is.

Let me know if you can help a fellow rider out, i'm trying to get this thing back on the road asap, and help bring some business to a local shop/person in the meantime. Thanks guys.

What bike?

You need a 20 ton press and a crank truing jig minium & 2 indicators. (a crank fixture helps)

Your best bet is to send it off, most shops around here are $$$ or dont have the ability

you cant beat this guys prices...

Hey its a xr650l

thanks for the info. I'm thinking that it might be better to take it to the guy in baltimore. When you include shipping I imagine it will be about the same price. And add on top of that the turn around time...

including the new rod, i gotta get my cylinder honed out (probably a new sleeve as well). I gotta find the time to get this all done, and i hope soon.

Actually the xr650l cylinder can be bored out up to 2.4mm. If your cylinder is stock size (100mm) there is plenty of room to take out any damage or if the cylinder measures inside service specs then a good honing to break the glaze will put you back in business. Let me know if you need the cylinder bored or honed because we have a boring bar at work and I can take care of it for you. As far as the new rod we ship them out to a company in NC because they can do them a lot cheaper than we can but the prices from the place in Baltimore are awesome so you might want to take advantage.

yup, mines already been bored out, so i'm probably looking at a new sleeve too. One guy i talked to said that the cylinder could potentially be honed out and be good to go. Not sure if he's right or maybe I misunderstood him.

In any case, if you'd like to do the work i'd be happy to bring it to you. I work in reston so if youre in herndon thats not far at all. And i'd be more than happy to pay any fee's associated with it. Just trying to keep the costs down and keep it local.

If it's only been bored once you should have plenty of room in the Cyl wall to go larger.
