You know, I was talking to a friend about how I ought to get the KTM back together, sell it, and look for another YZ450, CRF450, or similiar track only bike...BUT, I think I realize now that in the big picture, it's like the Duc (now Bimota).

Some bikes just cost a little more to own, but they are freaking worth it. I KNOW that I will have to spend 1000-1250 every two years or so in maintaining my Ducati motor/bike so it is done properly and to fix the little stuff that will go wrong (starter relay as of last ride), and I will still continue to do it. It's my vice and I'll enjoy it. It's much less ($50 per month average)than I would spend on the heavy drinking (or other hobbies) I would have to develop to decompress as often as the bike allows me to.

This KTM has been alot of fun and repairs are probably in the same ballpark on a monthly average ($50/month) from the time I have owned it.

There is nothing makes me grin more than a track day/Sunday Morning Ride/Hill Country Ride on the motard. LOL in the helmet is hard to beat.

Cheap costs for sanity.

And the KTM freaking rocks when it is sorted and happy. Let's just get em all fixed and hit GSS up again ASAP.

I also might recommend setting aside $50 per month for future use.

I'm embracing it. , I'm waiting for my LC4 to let go so I can finally see its innards. if it is anything like the forks were, it's going to be ugly.

TWS (Texas World Speedway) may do the trick this weekend. if not, there's always gss in september...

Greg I would recommend splitting the cases and cleaning everything out in there. There is no way to know if any little piece of ring made it down there, but chances are very high that it did. You do not want to spend the money to rebuild it now, only to blow the bottom end in 5 hours. Plus when bottom ends go, they are violent. Not like a top end which quitely fades away.

I had the same issue when I rebuilt my crf (minus destroying the rings). Check the cylinder and make sure you cannot hang your finger nail on any groves in the walls. If you can, you may need to bore and replate, or just replace it.

If you do tear apart the bottom end, might as well replace main bearings and seals, and possibly trans bearings and seals.

Welcome to the wonderful world of motard engines! At least they are simple enough to do the work yourself though.

im not very mechanical ... I was surprised i got this far. I had to get someone to cut the cam chain for me, but i ended up doing the rest.

I might have to bug linz and pay him in beers to help me tear it down and replace some things to save some $ not sure yet

ive been quoted upward of 1800 for complete rebuilt, and even got offered a new 4 hr motor for 1500. so we shall see

I can't speak for the others, but make no mistake about mine - it blew up because it was ridden hard and past the rebuild maintenance interval. Do as I say, not as I do.

The only reason my bike isn't back together yet is because I'm lazy, busy, was down for surgical repair, and, as important as anything else I've said, have a lot of buddies that don't mind me borrowing off them at the races.

I don't drink much beer, Greg. Bring Southern Comfort. But seriously, I'd probably rebuild yours before I did my own. I've been known to do that kind of thing.

Take it by Kerry's. Have him inspect the rod and internals. Order parts accordingly.

Dude, you're more than 1/2 way there, do as Lynz says....get someone to inspect and order the necessary parts and throw her back together, but you better find somone with a chain press.

Cut the cam chain with a die grinder. Protect the engine's open holes with rags while grinding so no extra gets down in the engine in the chance that you don't split the cases. Grind the pins off a chain link, toss the outside link, push rest of link out. Keep chain from falling into crankcase with a tie-wrap or safety wire or something like that. Easy.

Wes has a chain press. The link is a size 30, but a size 35 die works fine, too. Kerry is supposed to have a chain press, too. I'm counting on that, actually.

Kerry will tell you if you need a rod. I think you do, especially if the engine has a lot of hours on it, but the KTM rods are some of the stoutest you'll find in a 4-stroke single, so he tends to err on the side of conservatism. That said, RFS motors seldom chunk rods, but bearings and pins wear out.

Or, if your junk is out of the frame, just bring it over and let me look at it. (That's right, I wanna look at Greg's junk.)

Your junk doesn't look anything like I was thinking it would, thank .

I don't see any witness marks on the valves in these pictures. One exhaust valve seat looks a little funny, though. It doesn't looked properly seated. Not sure if it's the picture or angle or what.

Also from this picture it's hard to see any evidence of a leaking head gasket. Got pix of that?

Have you checked these valves to see if they leak yet?
