Next question, can you put a 250s jug on a 230s bottom? I have found a few cylinders with pistons as well as 250 heads with cams on ebay. What is your thoughts?

 

I have to replace my rings and head gasket on my 230, and I am building a second motor

 

You can, but you have to keep in mind the 250 jug is taller due to a longer rod in the 250, so you would lose compression on a 230 with a 250 jug. Taller jug also means longer cam chain. Then the issue of a 68.5mm bore. Where would you find a 68.5mm piston with the smaller 16mm wrist pin? A 250 has a 17mm wrist pin.

To me, the most attractive part of the 250 is the longer and bigger rod. Longer rod = more rpms and bigger = not breaking it. The 230 rod is so weak, that seemingly once you start burning oil and have to re-ring, the motor is junk. It will continually require re-ringing until the rod is fixed.

 

Oh, and if you get a 250 head, you have to get a 250 exhaust header. Probably worth it though. Why not ask the guy on ebay where the rest of the engine is?

 

Just wondering where you saw a cylinder and piston on ebay for an lt250s quadsport, I didn't see any and I looked a couple of times. They are all lt250s quadrunners, or thats what they say.
But if your looking for a good cylinder and head for an lt230, this guy has one cheap on ebay with .50 over bore. It says it came off a running engine and it didn't smoke. The piston looks new. The price is $112 or make an offer. Take a look, you could make an offer of $70 and he might counteroffer with like $90 and no thats not my cylinder and head, mine is only .40 over, but .50 would be awesome.

1mm = .040 inches... and .50 is likely in milimeters, therefore .50mm = .020 inches

 

If your wondering, it will give you 239.75752676625 cc's of power. So it will be about a 240cc engine

 

66mm = 229cc, 67mm = 236cc, 68mm = 243cc, 69mm = 251cc, 70mm = 258cc, 71mm = 265cc, and 72mm = 273cc

66 - 68mm in stock 230 sleeve
68.5 - 70.5mm in stock 250 sleeve

72mm in big bore 250 kit

 

My motor just bit it. Instead of rebuilding, maybe I should put something in with a little more power...... and maybe some fuel injection......

 

holy crap, everyones motor seems to be kickin the bucket. either i got lucky and got a strong motor or maybe it must be the climate here. i just bought a roost boost for my 230 with a AMR monster coil which i think may increse my throttle response by 20% i believe. what kind of fuel do you run? i run around 100 octane and still going strong on the OEM piston.

oh and for the people who have been wondering what a roost boost is. it is and igniton add-on made by Answer. it suposed to boost your spark andmake a 230 more fuel effecient. sounds kinda odd to me, i can ride WOT for hours on a tank of fuel.
