    European trackday experience / contacts?

    Hey everyone, I'm looking for some advice and help. Has anyone done any trackdays in Europe, particularly in Italy, France, or Germany? Do you have any friends or contacts that do trackdays there? I am trying to plan a trip this summer, but I don't know how things will work with the language...

    Dying of cancer, but I have a dream (18 tracks, 13 countries) - RIP, Jonathan Ko

    Who? My name is Jonathan and I am a long time member of BARF (I bought my first bike from yanabanana over 10 years ago), and admittedly not particularly active since I live in Seattle now. About 2 and a half years ago, I was diagnosed with cholangiocarcinoma, or bile duct cancer, which is...

    why *must* brake fluid go bad?

    Random question. We all know brake fluid is hydrophilic and will go bad if left in an opened container. My question is, why does this have to be the case? I have noticed that the brake fluid container is not airtight after opening. If I squeeze out all the air in the container, then close...

    want to diagnose weird noise?

    Hey, Anyone want to diagnose some random noise off the internet? My gsxr doesn't really sound right to me. I can't really describe it. Maybe a bit clunky. I have no reason to think that there is anything wrong, though. Starts up and rides well, valves are in spec. I've attached a zipped...

    electronic suspensions

    Electronically actuated valving this seems like an interesting idea. Any reason why it wouldn't work on a motorcycle? Why doesn't motogp use them? http://www.tomsguide.com/us/cannondale-bike-suspension-terrain-shocks,news-6203.html

    new carbs, installation questions

    Hi all, I just bought some new carbs for my cbr on ebay. Is there anything special I need to do when I install it? I know I probably have to sync the carbs, but anything else I need to worry about? Do I have to adjust the needles and jets? Thanks.

    15000 miles, shock service?

    Hi all, I have a 2004 gsxr 600. I'm taking it to a suspension shop to have the forks serviced and shock resprung. The suspension shop guy suggested I have the shock serviced as well. Is he trying to upsell me? Is it worth doing at this point? Thanks, Jon

    one cylinder not firing

    Hi all, So cylinder #3 on my bike is not running properly. The header pipes for that cylinder just doesn't get up to temp. The bike is running just ok. It does feel like one of the cylinders might be off. I was able to do a compression test and it seems ok. Here are the readings (dry...

    milkshake oil on valve cover

    Hi all, I was checking my valves the other day. When I opened up the valve cover I saw this milkshake looking oil on the valve cover. Usually, this means water contaminated oil, but my bike is a clean 2004 gsxr600 with 15000 miles, no smoke, and oil changed just a couple hundred miles ago...

    lojack review/rant

    So I got lojack installed on my bike a couple weeks ago. Just wanted to let others know about my experience. I paid $900 for it with early warning feature. It basically makes lojack a bike alarm which pages/emails you if your bike is moved. I tested it yesterday, and the warning came about...

    what does "setting up suspensions" entail?

    Hi all, Just bought a new bike which needs its suspensions adjusted. I understand adjusting sag and can probably do it myself, but what do you do about compression/rebound? Right now, they are all at the factory defaults, and it feels harsh. Is there any good rule of thumb? I'm a lighter...

    seduced by new bike

    So my 98 cbr600f3 was recently stolen from me. It was the best. I knew every quirk, every little flaw. I felt comfortable and safe on it. Losing it hurt alot, but what better way to mend a broken heart than to upgrade to something hotter, younger, and sexier. So I just bought a 2004...

    would you buy this bike?

    Saw this bike on craigslist. It's a 2005 cbr f4i for $3500 This is a really nice bike with 7623 miles on it. I put it in my garage over 2 years ago and it was running great. After winter, I went to start it up and it wouldn't start. I took the seat off and found a mouse nest under the seat. I...

    would a gsxr600 work for me?

    So I recently had my bike stolen (f***ing thieves!) and I am now looking into buying a new one. Old bike was a 98 cbr600 which I mainly used for riding around town and trackdays. I'm thinking about moving up to a ~2004 gsxr 600. I liked my old bike because it had more relaxed ergonomics...

    safety fail

    I don't usually do this, but saw this vid on youtube. Don't know if it has been posted before. Search on "safety fail" turns up nothing. http://www.youtube.com/watch?v=8uAcmrUEp2U&feature=PlayList&p=E38B57E5035099D4&playnext=1&playnext_from=PL&index=4

    washed bike, now won't start

    Hi barfers, Hoping for a little advice. I washed the bike yesterday, and now it doesn't run. Unfortunately, I was pretty liberal with the hose. I could have perhaps shorted something or got water somewhere I shouldn't have. It was running perfectly fine before that. This morning, I was...

    rearset installation problem (connector won't fit)

    Hi all, Hoping you can give me some advice about my problem. I bought a rearset with the rear brake switch from woodcraft and went to install it. The oem brake switch comes with a male connector, but the woodcraft one is the female version of the same connector. Woodcraft tells me to chop my...

    track technique question

    Hi all, I just got back from a trackday, and boy are my legs tired... My quads and hamstring are the worst. It seems like the hanging off riding style forces you to support yourself with the inside leg and not much else, since your arms are supposed to be pretty loose on the bars. Is this...

    measuring tire pressure at the track

    So what is the right way to do this? I know you are supposed to measure pressure on a cold tire, but I would think pressure changes alot with ambient temperature. Do you check it between sessions?

    quick brake questions

    Hi all, I'm rebuilding my brakes and ran into a couple small problems. Here is a picture of a set of pads. The wear is actually uneven. I'm wondering if I should reuse them. No big deal if not, since I have extra set of pads. Also, the manual calls for the caliper pin to be lubed with...
