hello Everyone,

My name is Juan..I recently purchased a '09 Honda Rebel 250, this is my first bike and I recently completed the MSF basic rider course. I am waiting for my shipment of Jardine Slash Cut pipes, however, I have no idea about re-jetting the carb? Is this something I can do..or can I have someone do it like a shop? I have never worked on a bike before...I do have experience on cars..but not bikes. Also, anyone in the Los Angeles area? thanks.

thinking a 09 doesn't need re-jetting, but I could be wrong

I'm guessing it probably does, because all newer bikes seem to be jetted too lean by the factory to satisfy the EPA. But, I wouldn't do it till you first make sure. When you get the pipes installed, put in a new set of plugs (save the old ones, they are still good), go out and ride it about 100 miles, and pull the plugs. If the insulators are a medium tan color, the jetting is ok. If they are white or light tan, the jetting is too lean. You can find pictures all over the internet showing what a plug should look like with proper jetting.


If you find it is too lean, go up one size on the main and slow jets, and open the pilot screw about 1/2 turn more. Put in more new plugs, and ride it another 100 miles and check it.

If it still shows too lean, go up to the next available size. You will need new plugs for each test, but save them. By the time you get it right, you may have enough plugs to last for years.


FYI, my completely stock '04 plugs do show a slightly lean mixture, IMO. The plugs are not quite dark enough. I believe the '04 and '09 have the same jetting. IF the new pipes reduce backpressure, it will be even leaner. Jerry.

Welcome, congrats on the '09! I personnally like the way my original pipes sound. But here's a link to spark plug color.

Congrats on the new '09 Rebel. Got one myself a few weeks ago and have rode it a lot. I'm a newbie but I'm hooked for life on riding. I'm sure you'll feel the same on your new ride soon. Be safe and enjoy riding.

I personally wish the Rebel could be made to sound like a Harley, because they are my favorite sounding bikes, and one of the few bikes that actually sound like a motorcycle. But alas that is not possible. The Rebel does sound good at idle with loud pipes, but rev it up a bit, and you would swear it was a Briggs&Stratton powered lawn mower with a rusted out muffler.

I wouldn't want to try to make it sound like anything other than what it is. there have been many threads about trying to make a Reb sound or run like something other than what it is, and it still comes down to the fact that it's a Reb. Exhaust mods to make it sound like a Harley invariably fail, waste money, and potentially shorten the working life of the engine. If I wanted a Harley, I would have bought one.

I actually intend to buy a Harley, a pre FI pre Twin Cam Electra Glide. I considered a Sportster, as they are so cheap used, but they are simply too small for me, and uncomfortable even with forward controls (which are available for the Sportster from at least 100 different companies) I figure if I am going to get a Harley, I might as well get what I really want. While I do love the sound, the main reason for wanting one is it's simplicity. The EVO engine is actually designed to be rebuilt over and over again, and parts will always be available.


As for the Rebel, it is a great bike, and I love mine, both riding on it and working on it. It is also a very simple bike, but is not rebuild friendly due to it's pressed together crank, non replaceable crank bearings (not easily replaceable anyway), and the fact that it does not use cam bearings, when the head wears down, you have to replace the whole thing. I think it is possible, with proper treatment and maintenance, to get a LOT of miles out of the Rebel, as it is well built, but I will not try to rebuild it. While easy, the parts cost wouldn't be worth it.

And yes, I do wish it sounded better. Even using a 360 degree crank, British style, would give it a better sound, and some vibration. It's hard to tell what my own Rebel sounds like at speed, but the Rebels I have seen go by at 40-50 mph have no sound other than a kind of hum. I totally understand that it is what it is, and I like what it is, Just wish it had more sound and feel to let you know there is actually an internal combustion engine down there with pistons going up and down. Jerry.
