hi can anyone answer this for me? which one was the faster engine out of these choices? Cr500, Lt500 and the kx500engine....... i want the most tourque and power and hop up potential also lets go with the smaller engine the trx250r or the cr250r, Kx250, lt250r and the tecate 250 same question what has the most tourque and power and hop up potential?? thanks

 

yz350

 

Snowmobile/ Sled engines by far (Polaris, Artic Cat). You can bore and stroke your Jap quads all you want but will never touch a sleds power plant.

 

Kind of funny considering many cats use Suzuki/Kawasaki engines. Seen the new generation of 4 stroke sleds from Yamaha?

 

Suzuki/Kawasaki makes 1000 CC 2 strokes for sleds [img]i/expressions/face-icon-small-blush.gif[/img] Oh you mean the turbo charged blown 4 strokes that cant compete with a NA less CC 2 stroke ? Didnt you just prove my point ?

 

Now I'm far from being a sled expert, but if I remember correctly, Suzuki and Kawasaki have both made 2 stroke engines for cat in the past. Since Suzuki owns a decent amount of AC and is still supplying the majority of their atv engines, I would guess they are still making the sled engines also. Japanese manufacturers used to make some nice 2 stroke street bikes back in the day, the RZ 350 engine just now getting phased out now in the US(Banshee.) But I suppose they don't know much about 2 stroke technology right? I mean, Honda themselves have manufactured more 2 strokes engines then Polaris and AC have probably sold combined. How many sleds do you see in a typical winter down there in Kentucky anyway?

 

D'oh, maybe you should check the AC sled page, seems Suzuki IS still making the 2 stroke engines for them, lol[img]i/expressions/face-icon-small-tongue.gif[/img]

 

Isnt that what I just said ? Sleds not quads , he wanted to know faster engines that could be used in a quad correct ? I mentioned sled engines. You can bore and stroke all those Jap Quad engines all you want but it will never touch the powerplant of a sled. I also stated that Suzuki/Kaw make the Cat sled engines. Did you misread something or assuming something I did not say here ? I see sled engines used all the time in KY, there are some winters where we could use sleds and others not.

 

This statement kind of sounds to me like you didn't realize many sled engines ARE Jap engines. See, you put this little embarrased guy in here[img]i/expressions/face-icon-small-blush.gif[/img], and I take that coupled with the second part of your statement to read as a ? 1988fast250x lives in Georgia per his profile, so I doubt there are many sled engines locally available to him, where as I still see sleds for sale by the road all the time, even in July up here in the snow belt. Looks more to me like he wants a cheap, smaller engine that will fit into a rolling chassis without having to do major frame fabrication, something you would need to do to put a multi cylinder, 2 stroke, belt drive into a sport quad chassis. I am not even going to bother with what is more powerful per cc, 2 or 4 stroke. It is well known and documented you can get more out of a 2 stroke per cc per rpm. However, you do realise that using an expansion pipe is a lot like having a blower or turbo on a 4 stroke, right? Anywho, I am with maddog on this one, why not just look for a nice Banshee engine? Proven hop up potential and no shortage of parts in the foreseeable future since it has been sold unchanged for 20 years in atv form. Think of it as half of 468bbc's sled engine, just with chain drive[img]i/expressions/face-icon-small-wink.gif[/img]

 

Scooter there was no arguement here or misunderstanding (well on your part of what Im trying to say) , he wanted to know faster engines. He mentioned Quad Engines, I mentioned Sled Engines that COULD be used in a quad. You're stating because I stated Jap Quads that I was generalizing Jap engines all together. And thinking Im stating something that was not said. There are many sled engines in the 500cc and under that doesnt require anymore fab work then a Banshee motor and produce ALOT more power. And most people in KY dont purchase sled engines locally either. Just pointing out with the money he would spend on a quad engine , he COULD have a Sled Engine. You should see what a used $400 BRP 377cc Rotax and tran did to a Adult sized go kart... scary fun. An expansion pipe is not forced induction into any motor.Making the engine remove the exhaust gases out of the head faster is not forced induction. lol Unless there was a turbine(turbo) on the exhaust and then feeding back into the intake. You on the other hand was trying to compare a turbo charged 4 stroke sled motor to a NA 2 stroke sled motor and stating it was a superior engine. Now your backtracking and picking my posts apart like a troll. If 1988fast250x wants to look at all options I was just pointing out something different then the norm.
