    I can turn the stem for you or I can send the spec sheet so you can take it to a shop for them to do. That way you can use XR bearings on the CR/CRF triples and so on.

    If you could PM me the spec sheet that would be great as I have access to a lathe

    Ok. Gimme a day or two. I have to start my computer to get the link. And I don't plan on doing that until its time to go back to work.

    Any quick advice on a mid-range stumble? While in the middle of a ride sometimes my BRP sounds like it wants to cut out, I just gas it and it gets through. Or I gear up and it chugs on like the tractor it is but I always wonder why it doesn't want to run clean in the midrange? :ear

    Any chance you are rich on the needle? Is this a new issue? Have you made any other changes to the bike?

    i had a simular stumble after a rebuild, was running a 1mm o/s with old stock jets, i put the scott summers size jets in and the stumble went away and performance was better all round... i think mine just wasnt getting enough gas, although in the past i have had choke problems(sticking) to have the same effect:huh

    New problem, just started to act up. I don't have a temp gauge but it could be only when it gets hotter as it doesn't seem to do it when it is cold.

    Not sure mate - it stopped working last year when I was up your way ;-)

    I think it was probably the cable. I have gutted the old one to remove the light bulb holders and warning lights but I'm happy to send you the left over bits if you want.

    FINALLY got the bloody dash finished off, bolted up the few remaining parts and went for my first ride in about 12 months! I can't believe it's been that long! Unfortunately it was only a quick ride on tarmac but fun nonetheless.

    Unfortunately I'll be away for most of the next month or so, but hopefully sometime after that I'll get out for a decent ride.

    he used a KTM stem and milled it down to fit the fork in the cr250. Went to Germany for a supermotoweekend (training, erzgebirg), after a few table jumps it broke..

    I'm not saying it cant be done but you should know what you are doing. moreso with aluminium stems.

    not positive but I assume so.
    I did think of one thing, I put the baffle back in the muffler, would that screw with the mid-range?

    Putting the baffle back could make it run richer.
    I had a similar issue. Start up and off idle, fine.
    WOT, fine. Would blubber and stumble at certain points mid throttle. Chased it around with main jets with little change. Dropped the needle 1 or 2 notches (can't remember) and it cleaned up.
    Might be worth a try.

    Thanks, I can do that. I completely forgot about the baffle.
    Sounds like the same thing, starting better than ever, take off is good, full throttle good, just when cruising along in the lower gears. :freaky

    And....Like Dino mentioned, check/replace that choke plate once you have it opened up.
