    I would definitely recommend verifying that the depth of the indentations concentric with the bore in the bottom corners adjacent to where the slide bottoms are still at least .010" deep. If they are not, the emulsion tube is at risk for wear, which will cause an excessively rich mixture at low to low mid rpm.
    Has the slide lift hole area been increased by drilling? If so, slide guide, slide and emulsion tube wear will have accelerated as a result.
    Measuring the the indentations concentric with the bore in the bottom corners adjacent to where the slide bottoms is key.
    After having verified good slide guide and therefore emulsion tube condition, float needle condition, correct float height, and correct main jet size, yes.

    Regards,

    I think one difference is the Racetech assembly has their Gold Valve.

    Well actually, I've seen it more times than not on this forum so didn't bother! Its not really bad Internet manners per se, just more an inconvenience. As such, I've edited. :1drink

    Does anyone know if there is an issue with the Clarke gas tank caps? Mine's only 4 months old but is cracking across the top through the logo. I did a google search and there seems to be a few letting go but none in the same way mine is. I'm sure they're a good company and I could get a replacement if I hassled them but probably will have the same problem again in a few months time. I'd rather fix the problem once and for all. Are these caps a generic fit? Will any aftermarket MX type cap fit or are they brand specific?

    Hello,
    it seems that this thread is about 'newer' DR's.
    Mine is a '92 and as you know, different in many ways.
    I tried searching for older models but the search engine here wasn't helpful
    Where can I find data here on the older models?
    It's basically stock, except for a JE piston, tires and airbox-jet modes from Uncle Jesse.

    thanks.

    I just checked the sag, it is more than it should be so I'll add in some more preload and see what gives give. I'd like to get this to ride somewhat like my DRZ did.

    Tires? Probably sooner than you'd think!!!:clap

    How's the coffee?

    Sorry....good stuff.

    I just got back from a test ride after resetting the sag on the rear shock. Pogo stick gone. Rides pretty well, can't wait to get out in the dirt somewhere and see how it does. NM, CO, UT, NV, OR?

    You should plan to ride with us when we get out that way. Maybe a day or 2 or 3?

    I'll plan on it John. I would think NM, CO, UT, NV, OR would be a good test to see if you've got your suspension dialed in :D

    The DR is headed back together after getting the frame powder coated semi-gloss black. While it is apart I took the RMZ450 forks apart and the machine shop is cutting new grooves in the dampening tubes to shorten the travel from 12.2" to 11.5". This will allow me to set the forks down farther in relation to the Cogent rear shock so that steering can be made more responsive.

    Nevermind... figured it out. :)

    I had had a question about preload, but then thought about it a little more, re-read the ProCycle page, and answered my own question. I ended up going with 1" of total preload (0.47 kg springs). I also set the preload on the emulators at the two turn starting point suggested on the ProCycle page.

    It's now 4 PM and the bike is back together. I haven't gone for a test-ride because it's too damn cold, but it feels nice from just sitting on it and pushing on the front end.

    While I was out there, I installed that new case saver that they sell, and that fancy anodized blue rear brake clevis. I was hoping the brake clevis thing would help with the play in the rear brake. It might have helped a little... I won't know for sure until I ride it.

    The red pegs and shift lever are very sharp. Power coated also? It's so nice it'll be a shame to get her mudded up! :D It was 65F here in Nor Cal. Perfect riding weather.

    The red parts are paint, and I intend to paint the rear grab bars and my homemade bag racks red also. They are primered now. A few other parts will be red like the oil cooler brackets and little brake brackets. I intend also to paint the valve covers red- got that idea from the Husky 630. Thanks...

    Red and black have always been a killer combination. Love it. Those red accents really set off things ... and hide a lot of homeliness! :D

    The Huskies red heads are way cool. Great inspiration. :clap

    I dont want to start a flame war or anything.

    but my stock battery in the DR finally gave out.:cry

    im the second owner of the bike.

    it was wrecked and i have bin taping it back together.

    after being crashed having some covers smashed

    forks bent

    tank crushed

    tail of the frame slightly bent.

    the bike STILL rides awesome.:D

    i used to ride a ex250.

    dont ask me what year becuase i had parts from god knows how many different bikes.:stoned

    after being crushed on my buddy's ktm950 :muutt i realized

    i really REALLY "REALLY" !!!

    wanted my own dual sport.:ricky

    though i need to get the hang of dirt riding.

    my skills for a lack of a better term. SUCK in dirt.


    anyway

    back to the problem at hand. i have bin thinking about getting a antigravity battery. i read they are good. last long strong crank. but i haven't got any good answers on wether they can deal with the heat the dr650 puts out.
    this is my eco bike if it aint broke i dont fix it. i dont plan on farkeling up the bike. i love its simplicity and its get on and go ability. so no extra lights. at most i will just go to a dual headlight. since i hate the stock headlight output with a passion. its one of the reasons i dont like to ride at night. planning to just drop in a new bulb and see if its an improvement..

    dang i keep getting off track.

    sorry im a total noob here.

    i think this is actually my first post on ADV.

    i've gone on DR specific forums and thumpertalk but im hardly ever here.
    since this is the axis of evil for DR650's on ADV i figured i'd post here and deal with the onslaught opinions.
