250-500cc cracked swinger!! 09 wr300

well as most of you know i bought the Glenn Kearney bike. it showed up monday and I assembled it. i spend the last few days going over it. greasing all bearings, changing all fluids, adding goodies, chain, sprockets. basicly completely tearing it apart and re assembling it. as i was poking around with the linkage today i found this crack. i thought i would pass the info along. I am not in the least bit mad about it. after all it is a race bike and was ridden as such. im passing the info along because it could have been the was it was ridden or could be a flaw in the welding process overall. so give your swingarms a good once over. i hope it is just mine. as for now im gonna ride it and keep and eye on it. if it gets any bigger im gonna pull it and reweld it.

i def dont recomend you ride it. but, if ya gotta, drill a tiny "stop hole" on each end of that crack to prevent migration.

I'd strip it and get it rewelded...easier to weld that small crack than replacing the whole swingarm.

That will be easy to grind out and weld.

or you could scrap the whole bike?

Just keep an eye on it. re welding is really the only solid choice here
