What are you doing with the choke? You should set the idle adjuster and it should pretty much be done unless you're traveling up a few thousand feet. Sounds like you're riding around with the choke on at all times.

Know what sucks? Not having a tach on your bike.... I have no idea what my idle is

If there's a valve clearance adjustment that needs to be done, what would that do to the idle?

There's a few things that can cause funny idles...valve adjustment is one of them, carb sync is another. Could also be mildly clogged jets, Seafoam will sometimes clean up an idle nicely. If it were my bike, I'd do the valve adjustment, sync the carbs, and finish it off with some seafoam in the gas tank. Also, check that your choke cable isn't binding...I think you can see where it's actuating the carb by just looking at it while you open and close the choke.

the walkin dude posted:Looked through that page... 1,300 rpm is the answer to my first question, but what about my funny fluctuating idle? Are you setting your idle with the bike fully warmed up?

Yeah, the choke is a big stamped metal slide right on the front of the carbs. Can't miss it when you move the lever. Also, keep in mind that the 1300 RPM level is really a baseline. If the bike wants to idle at 1700, that's fine. Basically it should be somewhere around 1300 RPM. Still a good idea to do the adjustments/carb sync, though.

Odd question that I didn't see any good info on with a quick Google. What does a Ninja 250 engine weigh? I'm trying to figure out what the weight of the bike is without the engine...have a project I've been thinking about starting for a while now.

Electric, right now debating between a ninja 250 which is cheap and easy to get or something like one of the few street legal 50cc bikes which are harder to find. Hadn't heard of a rd350 build but that would be drat fun too. Either way it will likely be a long project but my goal is to run Deals Gap with it once and a while and use it as a test bed for a few ideas I've got.

Has anyone put on new grips or heavy bar ends to reduce vibration at high speeds? How much did it help? I finally manned up and took my 08 on the highway for the first time and after riding at 70+ for 30 minutes, my hands were pretty tingly. Definitely need to pick up some ear plugs, too.

There is a scooter repair shop down the street from where I work, and earlier this week I noticed a nice Ninja 250 sitting out front. I called the guy last night to see if it was for sale and for how much. He said its a 2005 with 7k miles and he's asking $1500. Is this price about right for that year? I've been looking at craigslist almost daily and the few in my area (memphis) are going for over $2k.

I've been looking at craigslist almost daily and the few in my area (memphis) are going for over $2k. That seems remarkably cheap to me, most of the ones in the VA area are at least $2000, and they seldom drop below $1800, unless it's for a really early 00s or 90s model.

I'm going to go take a closer look at it today. I really do want another bike, but I was hoping to wait until spring. If this bike is in good shape it feels like it would be foolish to pass it up.

Hey guys, if I dont have the tool kit that came with my 250, how does one change the spark plugs? What tools would I need from, say, harbor freight?

the walkin dude posted:Hey guys, if I dont have the tool kit that came with my 250, how does one change the spark plugs? What tools would I need from, say, harbor freight? All you need is a spark plug socket, a ratchet, a short extension, another socket (10mm I think) for pulling the gas tank, and some gap gauges to make sure the new plugs are gapped properly. Any auto parts store will carry the appropriate spark plug socket and gap gauge. Don't get this kind of gap gauge, as they're worthless for anything but being a keychain: Click here for the full 800x600 image. Get something like this, that has discrete gauges and a tool for adjusting the gap: Pull gas tank. Gently pull wires off spark plugs. Remove spark plugs with spark plug socket. Check gap on new plugs (.6mm to .7mm). They'll likely be correct, but always check. Brush anti-seize compound on the threads. (optional) Being careful to not crossthread the plug, insert the new plug with your socket and extension. Hand tighten. When finger tight, give it another 1/2 turn with the ratchet. Replace wires Replace gas tank.

Thanks for the guide. What spark plug socket size should I get? After intensive researching I found someone who suggested 5/8''. This cool?

Troubleshooting a 2003 250 that wouldn't start at first, and if it ever does will idle just fine, but dies the moment the clutch is pulled in 1st. It only sat for maybe 36 hours, I've been riding it regularly for months. The carbs haven't been cleaned in a long while, so that was recommended to me, as well as checking the spark plugs and making sure the battery's charged. Anything else I can check/test? I'm throwing in a bonus oil change while I'm working on it since the weather's still nice. So much for studying~

One other thing: always (ALWAYS) get NGK or Denso spark plugs; the Autolite and Champion ones have been known to disintigrate during normal operation, which can destroy your engine. Ask for: NGK Part No. CR8E (For the 2008 and later models) NGK Part No. CR8HSA (for the 2007 and earlier models)

Yup, I've got NGK CR8HSA's in my hands. But the singular question I have is if the 5/8'' spark plug socket I got is the right one?

Great. For my EX500, I gotta have a specific spark plug socket that has thin enough walls to enter the tight holes (ie, CRAFTSMAN deep well socket, or the Kawasaki tool). Does it matter on the 250?

The random socket I picked up at an Autozone worked fine for me.

Yeah, but I wanted to make sure. It's been around six years since I picked up a wrench for a vehicle, and I didn't want to screw up and end up with a stuck spark plug or something. Assurance is always glorious for a noob.

Cross-posting from the questions thread: So I'm following instructions for doing a valve clearance adjustment on my 250. Everything was going swimmingly, I extracted the spark plugs, and opened up the engine and started looking at the clearance of my first valve, the leftmost exhaust valve. So I went and started loosening the tappet locknut so I can turn the screw in it to adjust the clearance. Resistance. Resistance. Just wrench... not too much strength... then the rocker arm popped out of its hole. Shocked, I tried putting it back in and it was tough. The cam itself was preventing me from lining it up with the spring/valve. After much attempting, I decided to pull it out and look at it. It looked as if one of the "wings" pressing on the springs had been broken off. See that the upper part has that "wing" for pushing down. The other side looks like it's been broken off. I'm not quite sure. Are there supposed to be wings? And was it supposed to "snap" off like that? I was figuring that it would be an easy task, but the rocker arm popping out and a possible break of the wing part? How would I fix this situation? edit: Another picture to better see what broke off: the walkin dude fucked around with this message at 22:06 on Oct 5, 2009 |

Here's a better picture. I tried taking off the locknut off this broken rocker and it refused to budge. Normal? Should it spin up and down and allow for the screw in the top to be adjusted?

Can anybody recommend a slip-on or full exhaust for an 09 that's not horribly loud? I currently have a Two Brothers Racing carbon fiber slip-on that's really loud even with the add-on suppressor. It looks cool as hell but I feel awful subjecting the neighborhood to the noise.

I've heard many good things about them, mostly squids complaining about them not being loud enough and old people saying they are just right. As to moving up in size, I still can't get anywhere near my 250's limits so I don't see a reason to upgrade. Once the bike has nothing left to offer me in the corners I'll probably move on to a Ducati mid size like the 848 or some such. Torque would be nice.

SV650's are pretty dope. I've got a 22-year-old buddy who's had a motorcycle since he was 14 and he rides an SV650. Says it's plenty of bike for him, which means it'd probably be plenty of bike for me. I also like the idea of having more torque down low. Waiting to get to 8k rpm can be a little bit of a pain.
