I've run into a problem while trying to get a little 90cc running properly.



Right now, I can get it running but it has some serious problems at idle. First problem is that when it is at idle, the motor oscillates. It runs all the way to 5k rpm or so then drops down to almost nothing, then does it all over again endlessly.

Second problem is that if you try to give it gas, any throttle makes the engine die. If we take the choke off it just revs like crazy.

I have completely cleaned and reassembled the carb, cleaned out the petcock, , gas tank, fuel selector switch, and fuel lines, and have a pretty good hang of adjusting the idle and high speed jet, but nothing seems to be working.

Sounds like an air leak around the petcock.

Edit: Oh hey look at that, another page!

I was reading about valve adjustments on the new Ninja 250R and I see a quote that surprised me. This quote was regarding his local dealership not carrying shim kits because they just don't do many valve adjustments.

quote:

When I inquired about the number of valve jobs done on sport bikes the comments from two service departments was "they don't come in". They are often wrecked or sold before the first valve clearance check.

Is this a common issue in your experience? Am I going to need to have shims on hand in a variety of sizes lest I wait a week for them to come in on order?

No need for shims on the 250, it's you just have to adjust the tappets, There's a factory tool that makes it a bit easier that I bought and really like, but if you've got a good tool set you should be fine.

I've not seen this to be true for the 2008/2009 250Rs.

For those wondering, here's the valve adjustment guide I was reading. Looks like a bitch. I'm also digging the "from the factory" incorrectly set mixture screws which need the plugs drilled out and the mixture set properly.

Save yourself the trouble and just buy a hot cams shim kit. I find it interesting that they switched from the screw type adjuster to shim under bucket though. Anyways, 7.48 is a very common shim size, I've used mine in the ZX6E, ZX6R, SV650, FZR600, etc.

Edit: Almost all bikes are mixture raped from the factory to pass the emissions tests at certain RPM.

That's what the guy who made that guide I linked goes on to say he used. I'm picking mine up this weekend most likely so I won't have to deal with it for a while.

Did I miss the part where you bought a new 250?

I haven't bought it yet, but that's what I'm getting. The wife decided that it was dumb to get an SV since the 250 would be better to learn on and she can use it once I am ready to move on to a different bike. She won't let me buy one of the "ugly" pre 2008 250s and the cost difference from new in this area isn't worth the hassle of buying used.

The Ninja 250 people love those tires. Since 130/70-17 is the same size as the rear on the '08+ Ninja 250, have a link to the ninja250.org wiki which outlines all of the tires available in that size.

Yeah guy, take it to the dealer. Warranties aren't like car insurance; your rates aren't going to go up if you make a claim on your warranty. I don't fix a thing outside of routine maintenance and wear items on any vehicle I own while it is under warranty as that's the entire purpose of a warranty.

A leather suit and a full face helmet aren't going to save you from a tire moving at interstate speeds hitting you in the melon, pushing you head on into a concrete wall, and sending you over a bridge afterward. The only way you avoid that is huge helpings of luck.

Anyone with any experience with bike covers have a recommendation? I am unfortunately lacking in garage space so my bike has to sit outside.

I'm currently looking at this cover, but I am open to suggestions of known good covers. My primary concern is waterproof-ness and durability (won't melt on the exhaust, won't tear at the seams, etc...), with price in second, and storage size dead last.

Any suggestions for a tank bag for an '09 Ninja 250? I'd like to be able to hold my lunch bag when I go to work. I could probably make due with a cargo net for the lunch bag, but eventually I'd like to cruise up to my parent's place in Tennessee and a place to store a change of clothes or two would be nice.

Also, magnetic base or straps?

Doesn't matter as long as the bolt won't back out.

Phat_Albert posted:

Depends on the design. If the bolt has a shoulder, it may allow the spool to spin. Most that I see bolt tight to the swingarm though.

They have a section of no thread at the top of the bolt, but it is smaller than the thread and appears to be more for allowing the spool and spacer to sit directly on the bolt instead of on some threads.

I've worked on the threads for an hour with a tap and I just can't get the drat bolt to go the final half inch or so. It's got a good half inch or more of thread in the hole, but I'd much rather have it seat all the way to avoid any buzzing or rattling.

laymil posted:

What's preventing you from going the last half inch?

The threads in the hole on the swingarm are preventing it from going in all the way. They were extremely crudely tapped from the factory and full of gunk so the bolts wouldn't catch more than a thread or two initially.

Looks like I need to pick up some machinist oil or something to finish tapping them because brake cleaner must not be floating all of the metal shavings out good enough.

I've always wondered how you lube a chain with gear oil...just oil up a rag and wipe it down? Seems like you'd spill that poo poo everywhere.

I pour it directly on the inside of the chain (the top of the chain just before it is underneath the rear sprocket), wipe up the excess with a rag, and go for a ride to allow science to push the oil through the chain. I get a ton of throw off doing it this way but my chain is cleaner than when I use the grunge brush and chain cleaner stuff.

Jack the Smack posted:

Everyone tells me to ride before to warm up the chain, so that the chain is hot and can absorb the oil better. Then you let the bike sit for a while after cleaning and lubing. I personally oil the chain after I'm done riding for the day so it can sit overnight. Even the dealership's mechanics that I go to says this is the way to properly lubricate a chain.

I wasn't aware of rubber being able to absorb things, much less needing to be hot to do it. I guess the metal expands around the o-rings allowing the oil to seep past them?

Is there anything terribly wrong with the chain adjusters being a couple millimeters different side to side? It seems no matter how close I get them they move a tad when I tighten down the axle nut.

I know the "Hocks Noise Braker" sounds a bit like pseudoscience, but in my experience they really work, loud noises are significantly reduced, but you're still able to hold a normal conversation with the plugs in.

I always associate surefire with the tactilol arfcom crowd and that one dude who poses his family with guns and stuff. It seems fitting that they would offer earplugs with metal halos and poo poo to make it look like you're wearing an ear piece.

If you're destroying engines by running plugs with the wrong heat range, you've got other bigger issues that are destroying motors.

The plugs being the wrong heat range isn't what destroys the engine. The plugs getting so hot that the electrode melts and other pieces start breaking off and traveling through the combustion chamber, destroying poo poo in the process, is the problem.



Most people who have used the Champion plugs in their 250 just experience the bike running like poo poo or get stranded on the side of the road when the electrode melts.
