My bike was making clinkity noises for the past couple of weeks, and I found out it was probably the cam chain tensioner needing adjustment. I looked it up and performed the surprisingly simple operation, and now the noise is gone.

My question is: should I be planning to do something to my cam chain soon? Or am I safe as long as the noise is gone? I ride a Kawasaki EN450 if it helps.

race tires on road are a great idea, ask me!

Should be fine now that the noise is gone, just keep an ear out for it, but the adjuster should automatically keep it all sweet.

The wiki page I went to only has periodic emission inspections listed for Illinois, nothing on safety or VIN inspections. Easiest way to find out is to phone up the DMV tho.

Meanwhile you can all aspire to be these freedom loving states:

http://en.wikipedia.org/wiki/Vehicle_inspection_in_the_United_States#States_without_safety.2C_emissions.2C_or_VIN_inspections

Add Oregon to that list - the only inspections are emissions tests, and those only if you live in the Portland or Medford metro areas (and only for four-wheelers, bikes are exempt).

Given the Merlin had a 6:1 compression ratio, redlined at 3,500 rpm and only made 45bhp/litre, even Harleys have more sophisticated engines. The Merlin even had carbs (and so was reliant on the wonderfully-named "Mrs. Shilling's Orifice" in order to not stall under negative g).

(Yes, yes, I know the Merlin was supercharged and even turbosupercharged, so the compression ratio is pretty irrelevant)

I have a question.

Hypothetical situation. (That I've hit twice this year)

Bike has sat long enough to have the bowls empty.

Bike has vacuum operated petcock with ON-PRI-RES.

How long typically should it be left on prime to fill four ( :smug: ) bowls?

You can always justify it as being one of the reasons you were capable of getting 22,000 miles out of a 690 without catastrophic engine failure. I mean, it makes as much sense as using their specific oil, right? :ohdear:

Early engines had excessive wear on the roller rockers, that's the only problem I know about. I'm not sure why everyone thinks they're time bombs.

Although I don't like not being able to hear my engine as well (shifting), for longer trips earplugs are a must unless you dig tinnitus. In-ear headphones work fine for music listening.

I do it every day, but it's reportedly legal here. I keep the volume low though so you can hear things around you. I don't think my rides around town would be nearly as enjoyable without some music to listen to along the way.

8 hours of music takes some battery life. If you're piping it through the bluetooth piece you're also using for nav directions it probably won't last. I recommend you save your phone battery for emergency calls unless you have an on-bike charging setup.

Ah, thanks. I was a little paranoid that I'd have to replace the cam chain or something. I'm getting better and better about being afraid of mechanical jobs, but I doubt I'll ever get rid that small niggling feeling that I forgot something.

Which today was totally justified, as I realized half-way home I forgot to plug in the radiator fan motor :downs:.

For those that listen to music via earbuds...how do you get them to stay in your ears after putting on your helmet? The neckhole of any fullface helmet I've used is pretty tiny, and it knocks out any earbuds I attempt to wear.

IF you envision yourself on long rides repeatedly:

Get a set of Bluetooth helmet speakers and a phone power adapter for your bike. If you ride any kind of boring long distance it is easily the best money you'll spend after a seat (if necessary), enables you to hear gps directions without staring at the screen, and you can still wear real foam earplugs underneath for wind noise protection.

Grab your helmet straps with your hands and use your thumbs on both sides to push the earbuds in while you pull the helmet down over your head. This should help keep them in. Also, pull some slack up above your collar so that when you move around your shirt / jacket won't be pulling them out.

Use your thumbs to squish the helmet pads so there's like a channel leading to the ear spaces in the helmet. Pull apart a bit, and it should slide on without grabbing the buds. Make sure you've got some slack in the wire, or it'll pull them out when you head check while riding.

alright?
I put some holes thru earplugs that I cut a bit shorter and have been using those. As long as there's a hole all the way thru the sound comes out well. A soldering iron or hot nail on one end make a smooth hole that can wrap around the headphone end. I do that first, then drilled the hole thru the rest of it.

As for them falling out, the foam helps that for one, but I tuck mine thru my helmet strap. After I feed the strap thru both buckles I put the cable in between both buckles, then finish threading the strap thru. When you pull on the cable it tends to just pull on the neck strap.

Also make sure you're using in-ear-canal type earbuds, with a silicone or squashy foam tip, and not the type that typically comes with your phone and just lodges in the outside part of your ear. The latter type won't do poo poo to reduce exterior noise and you'll have to crank the music to hear anything, which just means more cochlear damage for you. And, the former doesn't pull out as easy if you get a set with a good fit.

I've been pimping old-school Nokias as bike-use phone/GPS/music players for a while now, but now I can update my recommendation to include the new Lumia 520 - GPS (but no compass), free turn-by-turn navigation, somehow a capacitive touchscreen that works with gloves (or maybe it's just the best resistive touchscreen ever), and pretty good battery life (2 hours with music player playing and GPS navigating dropped the battery indicator by 15%), and you can get it handset-only for £130.

On a related note - someone, I think it was here, posted a little circuit suitable for underseat mounting that you could use for charging a phone, but I can't find it any more - anyone remember who and where it was?

I can still hear my exhaust (which of course is legally restricted to below the danger level for long-term exposure) at 100mph, so maybe my crash helmet is just extra-quiet or something.

It's not like hearing gets bad to a point and then stops tho. It keeps progressing. My dad and my friends dad are both starting to lose their hearing and neither one of them will put in loving earplugs. It's pretty infuriating because I'm the one that has to repeat myself when he DGAF.

Uh yeah, this. Your bad hearing doesnt make you immune to further hearing loss.

Oddly enough, my dad has terrible hearing from loading bombs on planes in the air force in vietnam. Apparently one of the last things they would do before the plane took off is load the bombs, so the engines would be started and decently spun up as they were loading, and the air force didnt require hearing protection back then, it was optional :gonk:

Dunno specifically for your issue, but my bike makes funny whistling noises out of the gas cap when it's cooling down (like right after I turn it off). I found out it's just gas vapours venting, and it's extremely common and normal for my model to make that sound. Maybe your issue is the same, but they designed the vent better so it doesn't whistle,and you're only now noticing it cause you got it wet?

Not sure what kind of bike you have, but on both of mine the 'cap' covers both the sealed tank opening and a drain ring for rain / washing water. There should be a drain hole that goes to a tube that dumps down near the bottom of the bike. That way if you open the cap after a rainstorm it doesn't dump a bunch of water into the tank. Worth a check to make sure this tube isn't clogged with some crap.

If it's the old-style screw-on cap then I have no idea, but hosing your bike down is going to cool it off so the tank is more likely to be sucking in air than blowing out fumes.

I have a ninja 250 and it does this when it's cooling down. Can't offer much advice because I only bought it a few weeks ago, but from searching around on various forums it seems to be normal for this bike. It's actually pretty loud sometimes, like someone making a high pitched humming sound. What kind of bike is it?

There's a pressure-relief system built into the gas cap to keep the tank from exploding when it's mostly empty and gets hot and all the vapors expand.

No worries.
