How long is it a chain should generally last?

Earlier this year (Feb maybe?) I had a new chain & sprocket set fitted and I've had to constantly tighten it up from it getting slack every few weeks, cue last night when I lubed it up and tightened it to the point where I've maxed out the alignment guide and even then it could stand to be a little tighter.
The only thing I can assume is the chain is mismatched to the bike? (It was a DID kit I ordered from wemoto.com which is normally pretty good)

I have changed two chains. Both had over 12k miles. Another chain went 15k miles with no need for change.

I can say fairly confidently it's the same lever even though the TW200, TT225, XT200, and BW200 all use different part numbers for their lever assemblies. If only there was a database of diameter and spline pitch of kick start levers I bet you could source one super cheap.

Bigger than just me saving money on my kit is to assist the XT225/TW200 community in not being charged $350+ for kickstart kits. Instead we can source parts from the TW200, BW200, TT225, XT200, and XT125 to build a kit. So sorry for the effort port. I just wish there were junkyards for motorcycles like for cars so you could get your hands on the parts and do measurements without having to buy them.

You have an XT or a TW? Both my Tdubs have been kickstart so I can't help you on parts but let me know if a picture or measurement might help. $350 is a pretty insane price for that kit, considering for around that you could probably get a whole motor with kickstart, but that's only for the TW because I don't think the XT ever had kick?

Have you seen this?

Me too, I run into this lots with shocks/forks being put on bikes they didn't come on. I'll be interested to see what your results are in the end, do you have access to a lathe?

Did you lube it regularly? That's like way, way too short a lifespan unless you just fitted it and forgot about it. What do your sprockets look like? Post profile pics of sprocket teeth, top down pics of the chain riding on the sprocket.

Was it fitted with the adjusters as far forward as possible? What bike, what chain pitch (numbers on the links)?

I have an XT225. Thank you for the offer on the measurements. If something goes awry that may be useful. That thread was the impetus for this project. That parts list will run you $300 shipped minimum. I'm currently at $150 shipped and that includes a clutch holding tool, new seals and o-rings, the clutch lock washer, etc.

To my knowledge the only difference between the XT225 and TW200 kickstart assemblies is a slightly different lever size. Same diameter and spline pitch though. They never put a kickstarter on the XT225 stock but it is a "bolt on" modification requiring no custom work.


I'll post results after attempting to install my cobbled together kit. No lathe here nor do I have any machining knowledge.

Yeah there is very little difference between the XT and TW motors. XT is a 6 speed with a shorter countershaft. In fact, one of the "hot" mods on a TW is to take a XT or TTR motor, split the cases, and install the TW shaft. I think there's also some machining involved. Then you have a TW225 with a 6 speed. There's also a guy on the forums making a countershaft "adapter" to go on the XT225 motor for an easy swap, but that sounds sketchy to me.

Common misconception that; that fun is relaxing. If it is, you're not doing it right.
My (admittedly rushed) tank paint job is starting to rub off where I grip with my knees. Is the answer "more than 2-3 light coats of clear next time"?

It's a Gen1 KLR so I'm not going for concourse quality here, but did want to redo the tank, apply repro decals, and have it last reasonably long. Once the decals are on future touch-ups are probably not going to happen, so interested in getting it to be semi-lasting.

Surely there are though? We have them in Australia, though some of them have pretty ludicrous prices (one wrecker in Melbourne wanted basically as much for a KLR centrestand as it would cost to buy a new one from the US and pay for international shipping + GST).

my paint guy says correct curing is more important than many coats. 2-3 light coats sounds like not enough but its up to the individual clear coat in the end

If it comes on right after starting it's probably the headlight. This may be stupid, but are you sure the low beam is on and you aren't just seeing the running light on that side?

The high beam and turn signals only cause failure warnings after you try to use them.

Welp, it stopped coming on. May be the signal lamps' connection is a bit loose since I dropped the bike and it separated for a moment earlier? I will root around in them if this comes up again.

Thanks for your suggestions!

You were totally right! Headlight is dead. Now I know what the running lights are :v:. They seemed bright enough in the covered parking that I didn't notice... It was fun to discover this distinction at the tail end of a 450 mile journey.

I did the same thing the first time. I've burned through two low beam bulbs already. When I asked the service people about it they just said it was normal due to vibrations.

It looks like a simple enough bend, but I honestly have no idea what I should do to straighten it. Do I throw it in a vice and just yank on it cold? Heat up the bend? Completely detach the spade and get someone to weld a new bit of metal on there?

gently caress knows. The box they shipped it in was slightly too small, and those flanges weren't adequately wrapped (and were sticking out of the box at one point). I assume it got dropped on its end off the back of a truck or something.

I just realised I didn't mention, it's a givi top box rack. The bent plate is 3mm thick steel of I don't know what spec.

IANAE but seeing as it's just a cargo rack I'd just put it in the vice and straighten it cold. Do it in one motion, don't go back and forth to get it perfect and you won't work harden it enough to matter. Then hit it with some rattlecan so it won't rust where the paint cracks.

take lots of pictures of the bend and the packaging from all angles first so you have proof it was damaged before you fix it.

How does a rev limiter work?

Sagebrush
Feb 26, 2012

ERM... Actually I have stellar scores on the surveys, and every year students tell me that my classes are the best ones they’ve ever taken.
It's an electronic feature where the ECU (or CDI box on older bikes) stops firing the spark plugs when you hit a certain RPM.

Engines without electronic ignition generally don't have rev limiters, although there are mechanical (usually hydraulic or centrifugal) systems that approximate that behavior. The spinning ball thing on top of a steam engine is called a "governor" and it serves a similar purpose, for instance.

Are the injectors interrupted too? Or is that why engines grenade when you bang them off the limiter for too long?

Slavvy
Dec 11, 2012

To add to the above:

Cdi's and older efi bikes have a simple spark limiter that just cuts off the ignition coils. Hitting the limiter sounds the same as a car, as in ringdingdingding until you change up/close the gas; the sound is the engine rapidly dolphin-diving over and under the limit rpm.

Modern fancy bikes often have 'soft' limiters that operate on a strategy. So let's say your maximum engine speed (the speed the engine is physically unable to survive, horsepower notwithstanding) is 10,000rpm, you might have a soft limit that comes in at 9,000 by retarding the timing and reducing power, usually in conjunction with flashing a shift light. Hitting it feels like the engine just doesn't want to pull anymore. This works great if you're actually riding the bike and it's gradually (by ECU standards) climbing up the revs, but doesn't work if you decide to whack the throttle open in neutral or something, so you'll still have an old style hard limiter at say 9600 as a backup.

As to why they grenade: a variety of factors but usually because you're putting in too much heat but not taking it out because you're standing still with your stunta krew instead of moving at 100mph like the designers intended.

As Slavvy notes, some modern engines have fuel-cut as well. Not all do and it's obviously impossible to do that on a carbureted engine.

If you're running the engine at full throttle but with the ignition going in and out, you're going to be dumping some unburnt fuel out the exhaust and you'll probably get a lot of popping and afterfiring. It may be over-rich for a few seconds afterwards and run poorly. It shouldn't cause any engine damage beyond whatever happens from running the bike at its maximum rated engine speed -- maybe you'll blow out your muffler cores but that's not a huge deal. Heat is a big problem (more combustion events per second, increased frictional heating), but so are more esoteric factors like the increased centrifugal forces on any rotating assembly, which increases the changes of e.g. your crankshaft blowing itself to pieces, or the connecting rods elongating (and potentially breaking) from the forces. It's a distance measured in thousandths of an inch, but if your engine is built to close tolerances that might be enough to run the pistons into the valves or the like.

Basically try not to operate at the redline for any length of time. It's fine to hit it with some regularity, just don't stay there.
