Default 2001 KX 250 cylinder

     

Anyone know what other years will work on my 2001 KX250? I found a few on ebay. I pulled the top end off last night, and there's 2 good groves all the way through the cylinder. Looks like I was about one ride away from catastrophic failure. Also anyone know if I can have mine replated? Thought I read in my manual that they couldn't be replated.

Not sure what route to take here. Any ideas? I'll get some pics of the cylinder. I would like to keep the stock bore. Although I'm not completely against a big bore kit, I would like to keep reliability. Feedback is greatly appreciated.

So far I've found a new oem cylinder for $302. I'm going to make a few phone calls to see what the shops say.

Well my local shop wasn't very much help. They want to sell me a new cylinder for $388. I found a 03 cylinder on ebay, but am trying to find out if it's compatible. I've heard of a 01 going into a 99. Not sure on what adjustments if any were made.

Anyone?

You can replate it. I doubt if you can get it replated with the same "stuff" that Kawasaki used though. Some say the reason for that is that no one in the business wants to risk their reputation by running what KX's used to come with. One of the best deals I saw recently was an offer by Eric Gorr to include plating for 190 dollars with porting or when you buy a piston. Maxpower does good work from what I have seen. I haven't had anything plated in 3 years though, so I am not sure who is really hot on it now.

Any idea about the cylinder swap? I was wondering if a 2002,or 2003 cylinder would work. My local shop was less than forthcoming of any knowledge. I know the 2002 has the same compression, but a smaller carb.

Here's a 2002 cylinder. Auction ends in 5 hours.

If it were me I would buy the Ebay one and if it wasn't right I'd relist it.

I'm thinking about it, but there's a 2003 that ends in a week too. I've heard better things about the 03 having a broader powerband, and it came stock with the same carb as my bike. Plus it looks to be in better condition. Through searching on google it appears that it may work. Just wanting to get a educated opinion. Hopefully someone can shed some light on this for me. If I can pick up a new cylinder for half of what it's going to cost to replate, and it will work, I'm all over it.

When I am curious about a swap I look to see if the part numbers on the linkage to the valve are similar, base gaskets and pistons, cranks etc. For instance yamaha ran the same head for at least 5 years on their 125's. the only piston change involved the pin size etc. I bet they would go with if you have the valve with it.

I've been looking at part numbers all day. I think it would work, but I'm going to call Millenium tomorrow to see if they have one in inventory. I'll just go ahead and get the right one. I don't want the hassle of having something not right.

I'm also going to contact NW sleeves tomorrow and have a talk with them. I'd rather have the cylinder plated versus sleeved, but price may play a factor. I can pick up a brand new cylinder for $302.

I would replate......however, you can install a 93 thru 04 cylinder on your 01, provided that it comes with the power valves! I have actually put an 03 cylinder on a 98 and only had to buy the center valve. I would stay with the 01 due to the fact that every year Kawi changed the power valve govenor, pipe, and black box settings and sometimes you can end up with miss matched parts that often results in poor performance. Of course every item can be changed out if you have the time and $$$$

Thanks for the info Crogg! I figured if I tried it I would run the risk of having something not right. Especially having to buy a new pipe because it doesn't line up.

Anyone recommend someone to do the repairs?

I contacted Millenium, and they're only 7 days out for the work with a price range from $175-240. US Chrome is 2 weeks out, and about the same. I haven't talked to Max Power yet, but their site says 1-2 weeks.

Go to ericgorr.com and see if he has one in the garage sale bin. if he does and it isnt the same year as yours call him and see what it would take to fit it. that would be the fastest.

I don't see anything on his site.

I just called NW Sleeve, and it would cost more for a sleeve versus a plate job. $278!

I think I'm going to go ahead and finish tearing it down, and then send it off to Millenium. The person I talked to was very polite, and took the time to go over everything with me. I could buy a new cylinder for a little more, but I think I'll get better results from having them replate it instead.

I've got enough going on around here that my wife wants done. She wont be heart broken if it takes me a couple weeks to get my bike running.


Any tips for getting the head bolts off?

I sent mine to phat head racing and had a 265 big bore done. Really livens up the bike and is only about 600 bucks for aluminum head and 2 domes all youll have to get is base gasket and the kit. Definatly worth the time and money.

That's a possibility down the road when I can afford to spend the money. I found another 01 cylinder that I'm going to try and get. Once I've knocked out a few bills, I may consider a 310 kit on the extra cylinder.
