I bet I know the answer to this, and I bet it's the same as Ammanas. My nifty new-to-me 2002 Ninja 250 sat all winter, and wouldn't start this spring. I don't remember if I posted here or in the "new to motorcycling" thread, but someone pointed me to the carbs. I drained the carbs and filled them with Seafoam, and let it sit for a while (a recommendation that a friend uses on his cantankerous 250's carburetor). Drained that, drained the tank, and put in clean new gas. It started! Then creeped up to 7500rpm and sat. If I touched the choke to turn it off, it died. If I looked at the throttle with intent in my eyes, it died. The next week, I started it up again. It crept up to 5000rpm, then down to <500, then back and forth. Same choke/throttle behavior. After a few minutes it slowed and died, and now won't start again. I passed the MSF class this weekend and got my license, so I'm excited to get out there and practice! The bike still won't start, though. Not enough fuel getting to the engine? Was the racing engine coming from the residual Seafoam? Am I looking at having someone who knows what he's doing take apart my carbs?

racing engine comes from the choke being open. you can try fiddling with the idle screw as ive been doing (to no avail). seafoam didnt help when i added 3/4 of a can to the gas tank and ran it/flogged it for a while, still runs at odd RPMs or wont stay running at all

-Inu- posted:Yessir I'm going to try 15/45 and see how it works. I didn't want to change the gearing too much because as much as I would love the low rpms for my commuting, I bang the thing around in the mountains way too much to justify gearing for top speed. I play in the mountains too. You can down shift, you know.  Where did you order your sprockets from?

It's mostly the loss of accel I'm worried about, since the 250 doesn't have much torque as it is. I work at cycle gear so I just ordered the stuff directly from Vortex and Tucker Rocky. Motorcycle superstore has a really good price on that Vortex sprocket though.

Said goodbye to my little Ninja last night. On to bigger things in the very near future. I've been pricing out insurance on all sorts of new bikes. My Progressive insurance rate with an SV and ZX-6R is cheaper than the one I got with my 250

Still the 250 though.

Thankfully the guy came inside and admitted to hitting "that red motorcycle out front I think" Even gave me his insurance card and I've already got a claim opened, faxed them a quote from a local motorcycle shop today, waiting to hear back. Now that I think about it I should call them and change my contact number since I lost my cell phone on Tatsu.

Fresh EX250 owner here! I just took delivery of BlueBayou's cafe-racer'ed out '04 Ninjette. She's actually customized it so much that she removed the tac. Anyone know of any cheap clip/bolt on tach that I can plug in and just clamp to the triple tree?

Well it'll be Modify Evolution's call, but I think she'll want to stick with analog gauges. Can I get some sort of simple little thing for cheap that has the proper rev ranges? Everything I'm finding from google tops out at 8k, some 10k.

Well, there's this: http://www.denniskirk.com/jsp/product_catalog/Product.jsp?skuId=407845&utm_source=google&utm_medium=cse The stock instrument cluster would probably be better though, since it comes with various useful idiot lights, a temperature gauge and a trip meter. http://cgi.ebay.com/ebaymotors/ws/e...id=120539098665

Wow, and yeah, $170 is well more then we want to spend. I was hoping for like $30. I'll talk to her, see what she wants to do. Might just put a stock cluster on it.

Everyone who owns this bike should go out and regear to 15/45 right now. I just got done swapping my sprockets and it feels like completely new bike. Cruising rpms are so much more pleasant at 80-90mph and downshifting to 5th still gives you some passing power. First gear is actually usable now, whereas before taking a turn from a stop would leave you redlining or having to shift mid turn. Consequently, downshifting from 2->1 doesn't feel like the rear is going to lock up anymore. There is a slight loss of acceleration but the bike is much more rideable now. It's noticeable but it isn't a deal breaker. You can actually cruise in the power band instead of having to basically click past every gear to get to 5th or 6th. frozenphil, I'm not sure if I'd personally do 41 teeth or not. Based off the feel of 15/45, I think 15/41 would turn the bike into a total dog. I only took the bike out for a 5 minute ride around the block so I can't comment on how much different it feels during a long commute, but I think 15/45 might be enough of an rpm drop. If you do wind up going 15/41 please post a trip report though! I'm curious how the bike will feel with that gearing.

At least on my 08 250 I find first gear to be very usable in traffic. I mostly ride on streets commuting. I think it just takes getting used to riding at 10-11k RPM, and knowing when you need to go into 2nd. I'm sure it's a different situation on the older 250's though. Downshifting from 2nd to 1st is kind of touchy, have to clutch, put rpms up and then ride the clutch a bit. That took a lot of getting used to.

Regearing will help with the downshifting issue...you're making it so that at 11k you're at a higher road speed, which gives first a great range of speed. So you can downshift while going faster and not be at 11k. Gearing is sort of a funny thing, it took me a long time to wrap my brain around how the changes in gearing would affect real world riding. Phil, I'd try swapping out fronts. Much cheaper and very easy to get an idea of what you want. 1 tooth up in the front is about equivalent to 3 teeth down in the rear.

This is what you said...you could just boost the front up to 16 and see if that gets you where you want or if it's too much. I only recommend this because fronts are ~20$ and rears are ~50$. Plus you should have access to an impact wrench so changing the front is way easier than changing the rear. I know the 250 wiki says it doesn't fit but this guy installed one on the new gen and it seems like it's fine: http://www.ninja250forum.com/index.php?option=com_content&task=view&id=105&Itemid=1 I'd obviously check carefully for any clearance issues anyways, but it should be fine.

I know the 250 wiki says it doesn't fit but this guy installed one on the new gen and it seems like it's fine: You don't even need an impact wrench to change the front sprocket, it's held on with two small bolts torqued to about 14 ft-lbs. I got the old sprocket off and swapped on the new one with the bike's onboard toolkit in about 5 minutes. There was more work involved in getting the chain slack re-adjusted.
