Has anyone ever added a helmet lock to their bike? My aprilia doesn't have one and the seat lock on my RD doesn't work any longer. If someone could like to one that'd be great because when I looked around for one I didn't have much luck.

Your aprilia doesn't have the passenger seat loop for a helmet?

Thanks for the feedback. The basic idea is that I want to learn how to handle roads of roughly these conditions:

So bad, but not like forest trails. If it comes to choosing between being able to go 2 up and learning what I need to learn for this tour, the latter obviously wins since I can ferry someone else around with the old Elite 80 (which is a pretty hilarious thing to do in San Francisco. Maxing out at 8 mph on some streets around here happens occasionally)

Eh, you'd probably be ok on a DR350, definitely would be ok on a DRZ400. Any significant freeway riding would be sketchy, but you could do it, you'd just be winding the hell out of the engine. Nice thing about the DR350 is the 6 speed gearbox, DRZ400 only has a 5 speed but has a fair bit more power, being water cooled and with some additional displacement.

The benefit however, is that my bike was in excellent mechanical condition, had a new paint job and was full of new parts when I finished while a ~$1500 KZ650 would still be a crapshoot.

My 700 did the same thing until I dicked around with the idle screws a bit. It was mostly happy with them being at 2 turns out but started on two cylinders most of the time. I found which pipes were cold and turned the screws out a quarter turn each. This seemed to fix the problem. It only runs funny now for a few seconds if I let it set for weeks.

I tried this and it didn't make any difference. My bike takes about a minute of cranking (spread out over 10-second intervals) before it fires up, and will only fire up if throttle is held wide open and even then, only the leftmost cylinders will run for about 20 seconds before the other two kick in.

I've seen issues like this caused by bad vacuum petcocks or clogged regular ones. They just aren't opening all the way so the engine is always starved, it will be extra evident when starting cause you will have to crank the hell out of it to get enough vacuum to flow fuel to start and then only the left 2 will run due to gravity feeding them fuel first.

If you have a prime setting see it it makes a difference but remember that Pri also means reserve on many bikes so you may have issues if you try to run it like that and use reserve to get to a gas station.

I can reiterate this. Guy wanted $1000 for my bike. Talked him down to $800. Was able to ride it home, but when I got it to the shop, it cost me about $750. Granted, I could have saved myself some cash by doing the work myself, but I'm a wrenching newbie, though I'll be attempting to do this in the future.

There wasn't even a proper air filter in it... just what appeared to be aquarium filter replacement smashed in the box :confused:.

I convinced a friend to buy a $650 ninja 500 from a towing yard. All we had to do was put brake fluid in the rear brake, and it worked fine. We did a full electrical rehal for $300 cause it had no working lights, but that's it.

Later she bought a ZX-6R for $2000 and spent over $700 fixing it.

The one thing I don't get about a potential petcock issue is that the bike restarts fine when warm, even hours after it was turned off.

I have a petcock that doesn't use a vacuum hose. I know it flows plenty fine because I accidentally turned it on while it was not connected to the hose, and spilled poo poo everywhere. Whoops.

The original F2 petcock uses a vacuum line, but mine was replaced by an F3 one at some point, which is gravity feed, I guess. I had to block off the vacuum line to stop the engine from getting an intake leak.

I'm using choke. It's even harder to start with no choke. Interestingly, my choke doesn't seem to work properly. At some settings it will make the bike die, at others, it will increase the revs as it should. I don't get it. Have no idea when valves had been done last.

You can get away with using a beam type one to ballpark it. The torque spec is 14.5 ft/pounds though so you can't use the one that's linked. Beam type ones are cheap.

You don't strictly-speaking need a torque wrench, as long as you can manage tightening the drain/filter bolts without over-torquing them. That said, a torque wrench is a handy thing to have, and the beam-deflection ones are both cheap and durable (ie they won't go out of calibration as easily as similarly-priced click-type ones).

Something like this:

Last spring when I changed the oil, the old one was black, the new one was light for five entire minutes and promptly turned black as well the moment I turned on the bike.

It was rather reminiscent of a winter day.
That reminds me, the winter killed my loving thread. :argh:

Are car engine cleaning additives suitable for bikes? I don't want to pour some nice expensive mobil 1 stuff in and later find out that I have soap on my clutch. I mean the additives that you pour into the old oil and let run for five minutes before changing the oil (and gawking at all the crap that was in it).

Also, should I change the filter? I only ran it 1000km with the old-new oil so I don't want to. I get a strange feeling like I've asked this before but I need to post anyway so I could click the question mark.

Just sayin', if you have the cash to spare for a few hours/days, you can usually hit up a Pep-Boys/Autozone/Kragen etc. auto parts store and "rent" one for the cost of it as a deposit. I paid about $100, used the wrench to change my oil, brought it back and they refunded the entire amount. So, free.

If you literally have $25 in your name, then this may not work for you. :v:


e; This is actually something they do, I'm not saying "buy one and then shadily return it later." Just ask if they loan out torque wrenches.

Well it ain't soy sauce!
I hope this is a good place to admit i'm a dumbass, because here it comes.

I did the first oil/filter change on my '83 KZ440 yesterday. I had a new filter cover bolt, drain plug, o-rings, and spring/washer ready just in case anything looked suspect.

According to my clymer manual the first two steps were "1. unscrew the filter cover bolt. Remove the spring and washer. 2. Remove the cover and filter, discard the filter."

Followed by the steps of putting it back together.

"6. Insert the bolt into the cover and install the spring and washer. Insert the filter and reinstall into the crankcase."

This confused the poo poo out of me becase
A) I'm a dumbass.
B) It wasn't clear on if the spring and washer were above the filter on the bolt, or below.

So when i removed the cover and old filter there was NO spring or washer present. Any thoughts of putting it back together based on what it looked like when it came apart went right out the window.

So i put it back in the was i thought it should go, and guess what? according to this diagram I put it in backwards.


Click here for the full 580x707 image.


I put the spring on top of the filter instead of underneath it, huzzah.

I went for a ride today and all seemed fine except for a bolt in the rear hub assembly that sheared off at some point. While looking for the bolt size i came across this diagram.

How bad of a gently caress up is this? Am i basically running with reduced filter efficiency because of the adjusted location? The oil pressure light never came on so i don't think the engine was starved at any point, although I did push it hard a few times. Should I get a new filter and more oil and do a whole new oil change when i fix it?

I did use castrol GTX 10w-40 for the change as it was recommended in multiple kawa forums for these older bikes.

Quick question: I bought a replacement carb for my KLR 650 from a guy, but when it showed up it didn't have the bracket that holds the throttle wires in place. It's essentially useless without this part, and the only place I've found it for sale is bikebandit where it's $40. The carb itself was $70. I told him this and all he replied was that he didn't have it. Do you think I should ask for $40 back? It seems like a pretty lovely thing to do.

update: did paypal dispute for $40 (being fair, not even asking for additional shipping costs) and forwarded the guys tantrum to the admins on the KLR forum

How long was your ride? If it was fairly short (say, <50 miles) then I wouldn't sweat it. Definitely change the oil and filter; it's cheap insurance. Your oil was going around the filter rather than through it, and the filter may have been damaged by being incorrectly installed.

E: If the spring and washer weren't in there to begin with, you were already in that boat. The PO didn't kill it, so I'm sure you did no harm. Kudos on having all the necessary spare parts on hand.

Question about Seafoam (prompted by this thread): How do people use it on their bikes? Just dump a bunch into the fuel tank and oil? Is it possibly to suck it into the engine using vacuum like the how-to video shows on a bike? I don't think my bike's got any engine vacuum hoses (doesn't need any emissions gear).

MrKatharsis

feel the bern
:eng101: Your bike has a fuel hose from the gas tank into the carburetor/FI unit.

As I understand it, Seafoam is for blowing out carbon buildup from incomplete combustion. Cars may benefit from this, as they typically go 100,000 miles at relatively low RPMs. This should never be the case for your typical motorbike, which will probably be wound out regularly and then get crashed, parked or parted out by 30k.

Half a dozen goons will probably follow up this post with stories of how Seafoam alone resurrected their old CB350s.
