i dont know what those numbers mean but i've ridden to the gas station on 10 psi and as long as you dont try to rip a wheelie your valve stem will probably be ok (tubed tire)

So actually additional question then. I’m presuming that the swingarm sticker is for the OEM tires. Would those numbers differ with non-OEM fitted tires? I don’t mean different width, just makes. My gut instinct is that it’s a “it’ll be close enough so just use the sticker value” thing. My 650 has OEM tires but my 250 hasn’t had anything OEM in quite a few owners I imagine. PO had a 150 or 160 on the rear which I swapped back to an OEM-sized but not OEM-make 130.

I have a good bike pump, I just remembered, but I converted the end to a quick-connector/disconnector for my road bike and I can’t remember if it’s presta only or not. I’ll have to see if it’ll still do scrader valves.

When removing and reinstalling an exhaust header, is greasing the exhaust gaskets just done to hold them in place, or is there some other reason I'm not thinking about?

Follow them because doing so will retain your warranty.

Serious question, is there any data logging in modern bikes? If I didn't volunteer the information, if my engine exploded, how would the dealer know I revved to redline for an hour on the hwy home in 2nd vs putted home at 20kph in 6th gear at 1500rpm in a bicycle lane?

I'm joking in the example, but I routinely rev to 8-9 before shifting. Before I rode it off the lot, the mechanic at the dealership told me to ride normally and just avoid revving over the limit for sustained periods. I guess by the letter of the law I've long since voided my warranty but I'm not sure how Kawasaki would ever know in case something ever went wrong.

You can get TPMS sensors that take place of the valve caps which require none of that AFAIK, but I’ve yet to see a positive review of anything that cheap — always seem a few PSI off, up to like 10 in some bad cases.

Has anyone ever built a motorcycle with a hydraulic drive? Like a pump on the side of the engine and an in-hub hydraulic motor on the swingarm and power transmitted through hydraulic hoses. Instead of a transmission you could have valves and torque converters. All the moving parts would be sealed.

I'd get a kick out of it

If I don't plan to use my Ninja 250 in the next few months, what would be the proper way to drain the fuel?

I'm thinking I shut off the petcock, unclip the fuel line from petcock, attach an aux line instead then let that drain into a jerry can
Run the bike until it dies of starvation
Drain the floats by opening the drain valve
Call it a day

Am I way off base?

I think I have a prime setting so I’ll run that, thanks. The fuel was stabilized way back when but I guess if I won’t be running it there’s no point in keeping it in there.

OK so like in all seriousness I don’t see myself touching the bike in 2020 so

Drain bowls yes
Drain tank no

I can live with that.


I will probably pull it out if I decide to do baby’s first track day next year, or end up selling it. Even then, new gas is cheap so as long as it doesn’t separate and rust my tank I guess I’m fine if I have to drain it next year.

Above advice aside, I’m taking my 650 in for its initial 1k next Thursday. Not for fear that I can’t do the work myself, but I’m going to use the opportunity to have them torque all the bolts on the exhaust properly with the right tools (my torque wrench didn’t fit up into a few areas so I had to guten tight a few bolts), and honestly just to give it a once over. After that I don’t think I’ll be taking it into a dealer again unless it needs major work I’m not prepared to do. I am having them put in the EZ-Drain valve instead of putting the OEM drain plug again so future oil changes will be even less messy, ideally.. At least not until I have to pop the filter.

My biggest failure with self-servicing the 250 was my inability to get a good alignment on the rear tire after adjusting chain slack. I think I ultimately spent a few hours going back and forth tightening, re-tightening, adjusting, re-adjusting. I don’t know what’s “good enough” and what’s “critical” when it comes to rear alignment, but given that it’s one of two wheels keeping me from being a meat crayon I was very anxious about getting it right.

When it comes to the 650, I might be gunshy about servicing the drivetrain until I get a good feeling on what tolerances are okay.

Thanks. In my case I think I was also having some trouble keeping the wheel parallel with the line of the bike. Once I tightened the nut on one side it would go askew just slightly, giving me cause to start micro-adjusting again.

But this is all for lack of practice. It’s just a catch 22 that I have to break — scared of wheel alignment because no experience, no experience because afraid to touch wheel. Once I do it a few more times I’m sure the nagging doubt will disappear, as with everything I’ve done on my bikes so far.

I gather it’s unlikely, but does anyone know where the KWP2000 port on a modern Ninja 650 might be? I’m interested in trying to sniff the protocol but unless I missed it, even the shop manual I have doesn’t go over where I can find this port.

I can’t tell whether it is something that should be standalone or connect to the ECU or what.

I had my first taste of ABS two weeks ago when someone yoinked out into a downtown crosswalk against their light as I was approaching. Super glad I had it, but the sensation was really weird. I wonder if I would have slid out on my 250.

Followup question about my Ninja 250 long term storage. My petcock doesn’t have an “off” position, only on and prime. If I just shut the bike down, fill the tank, and drain the carbs, will the carbs re-fill only once the engine turns on and produces enough vacuum to assist? Or do I need to physically clamp the hose line to prevent additional fuel from making it to the carbs.

So I literally do nothing, just avoid turning on the bike after I drain the bowls? Thanks, I’ll dry ‘er out tomorrow then.

I have a dumb question about the clutch. With the clutch pulled in, is there ANY friction between the plates, no matter how inconsequential? I’m trying to figure out why, with the clutch pulled in all the way, when I shift out of neutral into first I feel the bike clunk forward an imperceptible amount for a split second. Just trying to figure out what is imparting rotation onto what to make the engine or bike twitch like that.

Slavvy posted:

When you pull the clutch in you separate the plates by like a millimeter each, they are covered in thick sticky engine oil that easily fills the gap and create a sort of viscous coupling. And even on dry clutch bikes the drag from the plates rubbing past one another is perceptible. So when you clunk into first, the drag is enough to impart some small amount of torque onto the whole driveline (so the gearbox shafts, chain/shaft final drive and the cush drive in the back wheel), which is immediately stopped at the back wheel because moving the entire bike takes a lot more than that even if you aren't on the brakes.


RadioPassive posted:

Yes, when you pull the clutch lever, you relieve the spring tension holding the clutch plates together, but nothing positively forces them apart, so they slide across each other with very little - but not zero - friction/force transfer.

Makes perfect sense, thank you!

Has anyone had any experience re-covering a bike seat? Is it a tremendous pain in the rear end that I should just hand off to someone else to do?

My N650 seat is super slippery and I'm toying with the idea of buying a luismoto re-cover and the gel insert to throw on instead but somehow I imagine this is going to be much more fiddly than working on bike mechanics.

I probably won't bother until I find a reasonably priced parted out OEM seat on eBay.

Hmm interesting. I'm definitely interested in doing the thing now, but will probably still wait until I can find an OEM swap-in just so I can have a seat in case I royally bone it up.

OK I bought some of that seat gel from AliExpress and I’ll try to DIY on my own seat after watching a few YouTubes. poo poo is like $200 on eBay but $20 on AliExpress v:)v — was surprised there were no Chinese sellers on the ‘Bay. This won’t help with any actual slipperiness, but the stock seat is kind of hard anyway so I’ll replace that and if I still have a bug up my butt to change the seat cover in a few months I’ll buy the luimoto cover I’ve been eyeing.

My Ninja 250 was 50% self-sealing tape, by weight when I bought it.

Including a particularly large section of what was once rear brake line cladding.

No complaints on my Ninja 650. I put an aftermarket double bubble on there but more for the darker aesthetics than for need of actual wind protection. I won’t say it hasn’t helped a little, but the stock windscreen seemed fine IMO.

I ran the double-bubble at medium height for a while before moving it back down to “sporty” mode. The more vertical you put the windscreen the goofier it looks on a Ninja, and the protection wasn’t significantly better.



E: Assuming the tire doesn’t catastrophically shred, what is the sensation of developing a flat tire on your ride? What do you feel/how does it present?

I literally didn’t know that my torque wrench clicked when I first started working on my bike a year ago. I thought they were suppose to slip like the smaller bicycle and firearms torque screwdrivers I’d used before. It wasn’t until I was like “umm I’m pretty sure this is way too snug” that I realized the mistake.

Subsequently, I’m pretty sure my Ninja 250 oil drain bolt is torqued twice as tight as it should be and may or may not come out with an abundance of metal next time I pull it. Fully prepared to have to helicoil it which will probably be a hoot in and of itself.
