    OK.

    Still waiting on a brake line. Supposedly it will arrive tuesday. I still have yet to route my wiring completely, but it's in good enough shape to take for a quick test spin... so I did. I'm glad I did this. The ride is noticeably improved. I decided to shelf the gold valve for now. I just filled the compression side with 10wt and the rebound with 15 and took it for a ride.

    Nope, no oil cooler. Remember this is an R80, not a 100. They didn't come with one stock and as far as I'm concerned when left in stock low compression form, they don't make enough power (heat) to really need one. If I ever bump this thing up to 1000cc I'll add one.

    You're a dick, Jerome. I hope your luggage racks break. Again...and again.

    Actually, my understanding is these motors run cooler with higher compression.

    no problem Spencer, we all know you are a knob too. I beefed them up...the bike should break first:huh. Watch your aluminium cases then...:evil See you in April dude.

    This seems contrary to Boyle's Law of Gases, but if anyone cares to explain to me how this is possible I'd love to hear it. :ear

    i love this forum for posts like this.
    so, how many hit points does your mage have?

    Say what?

    I always assumed low comp = less power, less heat.

    Boyle's Law of Gases, actually more accurately, the ideal gas law establishes the relationship between amount (in number of molecules), temperature, volume and pressure of a gas.

    Given a fixed amount of gas (in number of molecules), decrease the volume and the pressure and temperature will rise. The more you decrease the volume the greater the temperature and pressure. Yes, a gas heats up as it is pressurized. This added heat and pressure results in an increase in combustion pressure and temperature causing a higher compression engine to operate with greater power and more heat.

    at least that's how I understand it...

    wow, lookin' good man!

    You may have said it already, but which lights did you put on your crash bars? While riding a twisty mountain road in dense fog this weekend it occurred to me that if my headlight winked out I'd likely run off the road--a backup would be a good idea.

    I put some Gold Valves in (well, actually somebody else did it for me at Datchew's Tech Day while I stood there with my hands in my pockets). They really make a difference. I can't feel any brake dive under normal circumstances, just a little when I crank down on the lever. I tried them on my 'bump test'--I hit a 6" curb at a steady 10 mph. I've hit the same curb many times so I know how it used to feel. I got prepared for the hit but nothing happened. The Gold Valves made it seem like I ran over a nickel. So far I can't see a downside. I think you'll really like them.

    They're PIAA 510 driving pattern (not fog) with "super white" bulbs in them. They're available on amazon for $145. Just be sure to get the driving pattern as I've heard that the fog pattern is so diffused that it's relatively useless. I'd definitely have no qualms at all about using these as my primary headlight. At 55 watts each they throw a healthy amount of light. I have them wired up to my high beam switch via their own relay as my primary headlight doesn't have a high beam. My "highbeam" is my regular headlight + PIAAs.

    i'm familiar. it's just not every motorcycle forum where you hear gas laws quoted.

    the mage comment was based on an extrapolation that if you're quoting gas laws during a motorcycle discussion that you're probably also a D&D enthusiast.

    Despite a fair understanding of the laws of physics, I DO get laid and I DON'T live in my parents' basement.:lol3

    I guess it's a good thing that the D&D lingo went right over my head.

    Just talkin shit and playing on stereotypes, no real offense intended. Sorry if that didn't come across. The last thing I mean to do is offend anyone around here, especially those that have helped me out. :freaky


    EDIT: I definitely didn't mean to imply that you live in your parents' basement and don't get laid. After reading that again I can see how that could be inferred. Woops. I give up. I'm an ass.:asshat

    i'm awash in sarcasm. no offense at all.
    i'd only be offended if i wasn't getting laid and was living in my parent's basement.

    I used to think the same thing - but evidently what really happens is that lower compression isn't as efficient. Instead of the charge being converted to mechanical energy, much more of it is converted to heat. Higher compression will 'extract' more power from the fuel and give better mileage.
