I haven't actually measured the engines to see if it would even be
possible to fit an EX250 motor in a rebel 250, but it seems like the
radiator and related stuff could be mounted on the rebel frame with a
minimum of hassle, and getting the front and rear sprockets to line up
should theoretically be doable, and I'm already thinking about how to
adapt the controls...Has anyone already researched and shot down this
idea? Or, conversely, know if it would be possible and have any
suggestions? I like the idea of the tiny little cruiser that can
actually go fast, . Plus, I'm over 6'1, so I'd look like a clown on a
tricycle on it, which would be pretty awesome. Thanks!

For 7 whole HP gain ??? Why bother ?

It'd be cheaper to pick up a used Ninja 500,, and you'd gain
30 + HP.

You can look like a clown on a little crotch rocket :-)

Take two aspirins and masterbate. If irrational delusions persist in
the morning, buy a Chinese or Korean cruiser and plot a strategy to
get it registered.

I suppose he could buy a small cruiser with the EX250 engine
already installed by Kawasaki... but it probably wouldn't
make him look enough of a clown.

All kidding aside that is a decent bike, half a Ninja 900 engine,
with belt drive. IMHO its descendant the Vulcan 500 is even better.

There does seem to be a certain type of hobbyist for whom stuffing
inappropriate engines into even more inappropriate frames is as
good as it gets.

True. I love my 454LTD, I have to sell it though. Too many bikes.
About as close to a cruiser as I want to get, but it is a great bike.

Hey now, 36 HP vs 18 for the rebel, that's double, good sir. I must
say, though, I never knew there was an eliminator 250. I've never
actually seen one. Rebel 250s are everywhere, and ninja 250s are just
as common, and I like the idea of picking up a cheap rebel and a
crashed ex250 and making a wacky frankenbike for $2000. Plus, de-
badging it and watching people try to figure out what the fuck it is
would be entertaining as well.

You must have seen different dynos than I did, I saw 20 for
the Rebel, 27 for the Ninja.

Because no one keeps them.

Or a non-crashed Ninja 500 for the same $$$, 60 HP and no need
to fuck with it :-)

Yeah, it'll bolt right up. I know a guy that made the swap in a weekend.
The only problem he had was the hose clamps fubarred on him when he took
them off the old bike so make sure you have a few spare clamps around. Have
Fun!

Awesome. Anyway, the ninja motor could potentially get me far more HP
than the rebel just because it's actually possible to find performance
parts for the ninja. Also, I don't need a ninja 500...I already have a
v45 Sabre and a kz650, I've got "cheap sport bike" pretty well
covered. This was inspired by me recently seeing a rebel with a blown
motor for $400 and a beat-up ninja 250 stuntbike with no title for
$300. I know that those kinds of deals don't come around that often,
but $700 plus some work for a zippy little goofball cruiser that's
very unique seems like not a half-bad deal. If I can find deals like
that again, I may just go for it.

Far be it from me to rain on anyones freedom of mechanical expression
but I would rest easier if I get the impression this is a practice run
before you get real serious about it. IOW: It is your first practice run
at mechanical artistry.

The reason is there are actually good reasons for doing swaps. Super
Motard with a combination of [MX, road bike], hill climb with a
combination of GP MX or in line 4 cylinders, V-twins, et cetera, land
speed record bikes cobbled together from road race frames and faring
with whatever engine class you think you can beat the clock with.

*BUT* you see the pattern here? Typically you combine two or more
separate genre such that you end up with a bike that is suitable for a
third. For instance, had you picked a chassis that is world renown for
its great handling but underpowered, it would make huge sense.

Because it is there is a good enough reason for me but it just makes for
more interesting topic if it actually solves at least one problem
without creating two more. You are solving the low horsepower problem
and maybe possibly getting a [braking stabilitiy, high speed wobble,
traction, gearing, cornering problem] because of your chassis choice.
Understand if you come back and say "I had to lenghten the swingarm two
inches to eliminate tank slappers" it helps, but you have to be
committed to learning stuff like that or risk finding out why they make
sandpaper out of tiny little rocks.

I understand, but they way I see it is this...they are both the same
size engine in the same format, with similar dimensions, so center of
gravity will change less than it would with, say, a fat guy riding it.
The top speed of a rebel 250 is around 80. Well, the ninja 250 I rode
topped out at about 92, so I don't think there's a huge chance of
increased wobble. The exhaust will be something to figure out,
because I don't want a sportbike exhaust on it, so I'd probably have
to re-jet if I can actually wrangle the rebel exhaust onto it, or
figure something else out. I know the rebel brakes aren't impressive,
but the idea isn't to have a canyon-carver, so it shouldn't be a huge
issue. Anyway, I figured that my first engine swap project SHOULD be
something like this, where everything is low-powered enough that if
something goes wrong, the bike isn't going to tear itself apart and
make me hamburger. It's all theoretical at this point anyway. The
earliest I could consider getting into something like this is 3 or 4
months down the road. I do appreciate the input.

Have you ever looked at the brakes on a Rebel? You don't want to go faster.

Buy a 450 Rebel or better yet get a bigger bike.
Anything CAN be done with time and or money and skills. Ever watched
junkyard wars?

That's what you're talking about here.

Why re-open a thread that was finished last March? Do you really think
that the OP is still interested in this mental masturbation?

My news reader or NNTP server had a hiccup and brought in a bunch of old stuff,
which I didn't notice the OP date on until it was too late.

That's interesting. I came back after the holidays and found
my mailbox stuffed with thousands of messages, some several
years old. Also, all of my recent mail appeared in triplicate.

Clear signs of admin troll pranks over the holidays.
