Ok so girlfriend recently revealed that she still owns a scooter that I knew she had 4 years ago, except it's been streetparked for 2 years and hasn't run in that span of time. It's a Honda Metropolitan so it's carbed and kick-able. What's the checklist of stuff I should do before trying to kick it on? Take the carbs off and submerge them in cleaner overnight seems like step 1 Drain the tank and put in fresh gas, then flush the fuel lines seems like step 2 New battery seems like step 3 Anything else I would need to do before trying to kick it over? (Obviously before I'd ride it probably also worth checking the rest of the fluids, oil, brake, w/e (Do these things even HAVE brake fluid?) Should I get a new battery in the thing before I try kicking it on, or will it start from a kick even if the battery is hosed? Anything else that I would need just to get the engine to turn over? edit: no brake fluid for me. Drum lyfe I guess.

Throw a spark plug at it as it'll likely be gummed up. Don't immerse the carb that is a stupid thing to do 90% of the time and will only cause more problems. Take it apart and blow out all the passages with carb cleaner + compressed air, immerse just the jets and emulsion tube if you really need to. You'll probably need to take apart the handlebar switch, ignition switch and associated connectors if it's sat completely exposed as they likely be corroded to poo poo. The brake light switches probably aren't in great shape either. It shouldn't need a battery to run but you really, really don't want to be kicking a mystery scooter that may or may not start at all so it would make your life a lot easier to have one in there.

Or at the very least hook it up to a car battery with jumper cables. It’s 12v, so it will be fine. Will definitely help with the troubleshooting as an ECU that’s not getting proper voltage can make it feel like you’re having carb problems, coil problems or any number of things.

If it's like other scooters the CDI will run off an AC stator coil and won't give a gently caress about the battery situation. But it's a Honda so may well be dependant on DC 12V just because they like to be difficult. Either way gently caress diagnosing a no-start when all you've got is a kicker.

Anyone have some recommendations on good motorcycle literature? How/why they work, history of development, comparisons between the different manufacturers, all the like? I'd be stoked if I could find some kind of course for learning the basics of motorcycle mechanics but I haven't had much luck there. In the meantime I've just been hungry for any kind of bike reading.

 my Harbor Freight one seems wildly overbuilt for what it is and is incredibly beefy, but certainly wasn’t $5, and is not what I’d describe as high quality even though I have no fear of it breaking within my lifetime. I feel like sometimes high end tools get into the whole weight reduction thing to their own detriment

Compromising strength for 'weight savings' in hand tools is definitely real and definitely idiotic. But I've also found cheap tools tend to compensate for poo poo materials with bulk as well, although my cheap chain tool came with pins considerably more resilient than the motionpro replacements.

In the meantime I've just been hungry for any kind of bike reading. I've had Modern Motorcycle Technology on my shelf for a few years. It's got a wide variety of technical stuff, but without going into full engineering discussions. Total Control by Lee Parks and Sport Riding Techniques by Nick Ienatsch both cover the generalities of how the bike works, in addition to being very good books on how to ride. You can also look for anything by Kevin Cameron of Cycle World. Good luck finding them at a reasonable price, though.

Ate poo poo on black ice trying to get to work this morning, bent the heck out of my shift lever but no other damage. Is it worth hitting the lever with a blowtorch for a bit before trying to straighten it out, or should I just go to town with a hammer? Also I should probably take it off the bike first either way right e/ womp womp

Being that it's bent at the weld I would probably just buy a new one, if it breaks there won't be anything left with which to shift.

Condolences. Dumping the bike on a cold wet morning is definitely something I've done. Just get another one, and don't mess with that one until it arrives. Chances are bending it back that much will cause it to snap right off and you won't be able to ride.

Jim Silly-Balls posted:I think that’s a picture of the stock one. They said they don’t have it off the bike yet Nah that's mine, I took it off after posting/before edit. It's supposed to have that big bend in the middle to clear the sprocket cover, the bad bend is the one right next to the peg. I ended up putting it back on without being able to straighten it at all, because I had stuff to do and also got anxious about snapping the peg off, which like HP said would render it totally unusable. It's sort of manageable, I won't be winning any races but I can just about upshift by tilting my foot and jamming it in the gap.

If you do try to fix it, heating it up with a torch is a better idea than bending it cold. There's a reason blacksmiths work with hot material. Heating it up will destroy any heat treatment in the metal, of course (the shift lever probably won't have any) and any surface finishing (oh well).

You know how many people are riding bikes with bent shift levers? Tons. Heat it up and bend it slowly, a little at a time. If it snaps, get a new one. Shift levers are usually cheapish.

Original flavour is £70-100  I'm trying to find out if there's any unofficial swaps I can do, because KX levers look like they'd probably fit and are significantly cheaper, like £10-30
