    For the front brake I was referring to the EBC sintered pads. Pretty much their best pad. They are well below the performance of the OEM Nissin pads.
    Both are rated HH ... the Nissin is worlds better in my experience, but do wear quickly if used hard.

    The red EBC Kevlar ones I use in the rear brake. They are fine for me, don't need a lot of power there ... and can still lock up easy enough. I tend to drag the rear brake, so the hard wearing Red Kevlar ones seem pretty good. YMMV.

    You guys are awesome, thanks so much for the help and all the great info on diagnosing the issue.
    I wont have another chance to peel away some tape until Monday when I am back at work (the bike is parked there) but I'll let you know what happens!
    It was just confusing because the plugs did not indicate a rich condition.
    so the consensus is remove some tape and turn in the mixture screw?

    Grifter thanks for your response and input. If I do seal the rims I will try to post results.

    You could adjust the pilot screw via the following method:

    Start the engine and warm it up. Lower the idle speed below the factory spec. Starting from a setting that is known to be lean (1-1/2 turns is likely but not guaranteed to be), adjust the fuel screw to obtain the highest idle speed. Adjust to 1/8 - 1/4 turn richer than that. Then, adjust the idle speed back to 1500 rpm. Report back with the setting.

    In order to determine whether, as Rumlover suggested, the mixture was lean before the tape was applied and is only now rich, you could gradually remove more and more tape, testing after each change. If he is right, there will be a sweet spot where it runs better than it does now as well as how it ran un-taped. If the problem gradually gets better as you untape, but never gets better at any stage than before it was taped or now, then you started out too rich and taping only made it richer.

    Regards,

    This was just a quick search, but I remember there being better videos out there.

    If I understand the instruction manual for the Vapor unit, it's basically just a handlebar mount. The mounting bracket goes around your handlebar in much the same way you'd install a RAM mount. Then, the vapor bolts up to that, so it sits closer to the bars than the stock unit. However, it looks like they make it very easy to fab up your own mounting system, so you could probably just do whatever the hell you wanted with it.

    Sorry I don't have a pic, but the Vapor does come with an aluminum bracket that you can use to mount it to the front of the upper triple clamp.

    Highway Dirtbikes has some interesting stuff..

    I'm planning on getting a billet Vapor mount from HDB and relocating my key switch this winter.

    Might want to double check that. Mine did not come with an aluminum bracket, but it did come with a plastic bracket that clamps to the handle bars. I believe that bracket you mention comes with the protective case that many order with the Vapor.

    I have been happy with the placement using the plastic clamp. It is actually is a better placement if you intend to keep and use the stock speedo (I like the mechanical odo and trip meeter).

    Hello friend, i think your DR need a chain adjustment, remember that the chain when is properly adjusted must move about 10 mm. More than that is a loose chain.. :deal if need a better reference, the maintenance manual may be helpfully.

    Hope it help.

    https://www.facebook.com/photo.php?fbid=10151276738467930&l=bedbb74d41 shows the dash on my DR which I am still working on with the Vapor installed . From the factory it comes with a little clamp/base that connects to your handlebars. Unless you purchase the high speed bar mount made from alum. I like it the light isnt over poweringat night and its always easy to see unless you are at a realy odd angle from it.

    Best carb for the trans-am trail.

    My BST has been modded and actually isn't all that bad, but I have been wanting to upgrade to the pro-cycle mikuni pumper.


    Doing the trans am this summer, are there advantages to one over the other?

    I am thinking I may have to rejet during the trip or have to make fuel adjustments on the road.

    You will not have to re-jet. I ran the entire TAT on a carbed bike. You'll never know the difference.
    BTW, 13K I believe was the apex of it.

    Wont matter, the engine is plenty big enough.
    A 610. Carbed I rode
    On a carbed 250, maybe you'd feel it , but not on the big bore DR and its not like your living up there, its up and over. Like I said youll never notice, The DR is the perfect weapon for the TAT. If your jetting is dialed in now, it will be fine for the trip Bri.

    For those of you who've tinkered with dr650 suspension mods I've got a question:

    If you could have ANYTHING done on yours what would it be; forks from a donor bike, different swingarm and/or shock or would the ultimate fix be too cost prohibitive wherein a prudent person would save the cash and apply towards a different bike altogether?

    That could be it. I did order mine with the "dash", but ended up not using the dash portion.

    I'd buy a different bike, or I'd buy the Racetech rear shock assy and Racetech emulators and springs.

    Thanks for the reply! I'll do some research on the racetech mods.
