Suspenders 43 Posted August 20, 2013 I bought a 2000 YZ250 recently. $800 and I ran it down the street and it shifted and ran. I have in the past always looked for bikes that are very lightly ridden and this was not. So far I have installed, Piston kit Cylinder Power Valve Stator Clutch cable hoping the clutch is sound. Crank seals & due to this, suspecting the crank bearings. Lot of money and it ran fine initially until I got home and wound it out and it all went sour from there. So now it is $1800 and climbing. Was it the right call ??? Share this post Link to post Share on other sites

AATA 0 Posted August 20, 2013 A friend of mine just last week asked me to rebuild a 1999 YZ250. Needed a new crank and complete top end. I priced it out and it was $1,000 on the very low end, but probably closer to $1500 after he fixed some of the other issues. He had 2 other Yz's for his sons, so it's now a parts bike. If it was in better condition overall, it may have been a different decision. But for a KTM RFS? If it just needs the cylinder machined, a new piston/rings and a valve refresh, it might be worth it. Personally I would take the money and put it towards a newer bike if it's in his budget and part out what he can. I parted out a 1996 XR600 for about $1200. I sold things very cheap (a lot of parts went to SDAR members) to make it a quick process. I'm sure he can get more for all the KTM parts. Something to consider. Good luck!

bikeslut 1 Posted August 20, 2013 He's currently beyond "punt"...he either fixes it correctly (what he's doing) or parts it out and loses money. He should, by all accounts, have a well functioning bike when he's all done Share this post Link to post Share on other sites

He should, by all accounts, have a well functioning bike when he's all done Sometimes punting it is about losing money. If it were my bike, I'd have to think about it a good long time before I decided. Anyway, fixing it should yield a good bike for Axel. It was a fun bike at the track, much better than my Husky for that job. Here's the start to a new life for this Katoom.

tntmo 910 Posted August 25, 2013 Under the valve cover it looks good. Untitled by tntmo2, on Flickr The spark plug shows some signs of oil burning? Untitled by tntmo2, on Flickr And maybe the exhaust ports? Untitled by tntmo2, on Flickr Austria....G'day mate! Untitled by tntmo2, on Flickr The valves also show the oil consumption. Untitled by tntmo2, on Flickr Oil on top of the piston. Untitled by tntmo2, on Flickr Scuffing on the piston skirt, I have seen worse. Untitled by tntmo2, on Flickr There are some nicks, pits and scratches in the cylinder. Time to get it replated or replaced. I'm not sure if they will show up on the picture Untitled by tntmo2, on Flickr Just my hack garage mechanic opinion, but I'm thinking piston kit, cylinder and head refresh. The con rod has some side to side play that has me concerned. If I can figure out how to post a video, maybe some of the less hack mechanics here could give me an opinion?

TrophyHunter 15 Posted August 25, 2013 Austria....G'day mate! I'm thinkin' Australia, but I'm a hack colloquialism guy... Looks like good calls based on my limited knowledge. I think there should be tolerance measurements on the crank. Share this post Link to post Share on other sites

paulmbowers 236 Posted August 25, 2013 If I can figure out how to post a video, maybe some of the less hack mechanics here could give me an opinion? My understanding is the side play is no big deal, and normal. If, as on my motor a few years ago, there is up-down slop, that'd be a no-go. Share this post Link to post Share on other sites

tntmo 910 Posted September 19, 2013 I made the drive up to San Juan Capistrano today to meet up with Bob Hulka (CAflash) from KTMtalk.com. First he took care of the cylinder head, cut the valve seats and installed some nice KibbleWhite valves. Everything on the head was in good shape, we put it back together and Bob even removed a broken bolt. He put together a new cylinder and piston along with a KTM gasket kit and sent me out the door at a very reasonable price. Highly recommend Bob if you need anything KTM related. PMB, he told me to say hi to you! Share this post Link to post Share on other sites

Bagstr 288 Posted September 20, 2013 Tntmo, I am curious as to your technique for cleaning the mating surfaces. Is grit on glass, or what?? Share this post Link to post Share on other sites
tntmo 910 Posted September 21, 2013 Tntmo, I am curious as to your technique for cleaning the mating surfaces. Is grit on glass, or what?? If you're talking about the head and cylinder, Bob Hulka used a wire wheel on a bench grinder. I usually use a wire brush. Share this post Link to post Share on other sites
tntmo 910 Posted September 21, 2013 Well, it runs! Almost done, need to change out the rear wheel bearings and install the chain. Got a fuel leak on the carb, hopefully I have an o-ring or that will be holding up the bike. Untitled by tntmo2, on Flickr Share this post Link to post Share on other sites
