84-85 tecate cylinder difference kxt / kx questions answered

[cr480r]

the kx cylinder on ebay is tecate cylinder. I contacted the seller about a couple of his listings, he doesn't know his parts. Even from the picture shown it is clearly a tecate part. I was looking at a kx cylinder while I was comparing the picture.

Great read and pics. Did Sprock Racing ever complete their bigbore KX cylinder??

I have my 250 motor here and will definately pick up a KX cylinder for it when I get the chance. Think I may drop it in a 300EX chassis instead of a bigger fourstroke.Maybe some green fenders to keep with the green machine theme...

I have a non-kips engine laying around too. My kx cylinder for it needs a lot of work before it can be used. I was thinking of putting it in a 85/86 lt250. The frame is already made for the side exiting exhaust. A blaster would be a fun one too

Thanks t3 lopes. That cleared up alot.
Ill know everything about this beast, then it will take my life.

lol

Damn it all. Turns out that the cylinder I bought was a kxt. He said he would refund $, but still. Oh well, it looks like the hunt continues. Perhaps someday.

Keep looking, it'll turn up somewhere. Half the fun is looking, good deal on getting your cash back too.

I only need the KX cylinder, got the ignition a while ago and have a new 38mil flatslide. I can't wait to try it all out. Think when the time comes I'll be using a KX500 reed cage as well. Should flow more then the Tecate cage and I'm gonna use my Vforce II in the KX500.

Hadar, you will definitly fine 1 . Just keep your eyes open and BAM there it will be . Thats how I found mine, for 30$ and 30$ shipping, 60 bucks . I couldn't pass it up. I love these freaken Tecates.

did kawasaki ever use a stator likr the tecate on any of there 2 strokes? I have a smaller stator. Is this the 83-84 stator?

[BigGreenMachine]

You have the 83/84 KX250 flywheel/stator and CDI (black box). It fits the Tecate and makes the bike rev up and down faster resulting in faster acceleration. I have the same setup, never got the chance to run it though.

[Tecate250]

why did they use a different,smaller setup? I noticed that the magents are bolted on. Can these be replaced? Also the same magneto is almost identical as a cr 80 mag.

[cr480r]

They use a smaller flywheel on bikes so they are responsive and rev quickly, The atv's used a heavier flywheel for many reasons, one is to run the lighting system, two is so it doesnt stall as easy(kind of a pain in the a** with a grabby clutch), and I think another reason is for safety. I put an 85' kx ignition system on my tecate and it really woke it up, It required slippping the clutch alot more, and traction was not as good. I dont think I would replace a functional tecate ignition, but I would definately buy KX if I was replacing faulty parts or rode at the dunes much.

Does the KXT piston/rings work in these cylinders?

[scooterroo]

i have heard conflicting reports. some people have said yes, that the kx and kxt piston is the same part number. yet some tell me they are totally different. i will eb using the complete kx setup with the kx piston and rings. that along with the kx ignition i got off you, the bassani pipe and answer hottip silencer, and the vforce reeds and 38mm carb, the thing oughta be a snot rocket.

All tecate part #'s have been superseeded by the kx #'s. Remember, The intakes are the same between cylinders. I have had both tecate pistons and kx pistons and they have always been the same physically. Cranks, rods, cases, etc are all the same. Don't let this confuse you. I've built several engines from cases up and wisecos are all the same#. And yes if you do it right, they are very quick. Infact quicker than i had imagined. My strong running tecate cylinder engine of last year doesn't have a chance against my nicasil kx equipped engine. You do however loose some roll on power in the mid range, where the t3 cylinder would pull through a bit harder, but then sign off early. Kx engines are meant to be ridden in the high rpm range more than later PV equipped cylinders. They make power, and lots of it but you have to be more aggressive to use it. In the sand it should fly. We'll find out this weekend.

Scott I wish I kept that ignition. LOL Sold my 500 and going to tear into my KXT once I track down the stuff I need. Would like to do a KX cylinder swap.

The midrange loss concerns me. There was nothing gained in the midrange tecat-z? How does the bottom end compare? I trail ride a lot and play on some wide open beaches/sand piles and like the top end/mid power. Maybe the KXT flywheel would give me an effective bottom/mid for the trail riding I do?
