    Hi,

    I checked my oil level today. I warmed the bike up for a few minutes, shut the engine off then checked through the sight glass. With the bike vertical, the level was hovering about 2 mm above the lower mark in the sight glass.

    Could this have caused any engine damage? I changed the oil 1000 miles ago with 2 quarts of oil and a new filter.

    Also, the bike has a small leak opposite the side of the cam bore plug - near the spark plugs. This is probably where some of the oil went. I am going to fix this soon.

    Thanks.

    As long as the oil is above the minimum you are completely safe. That's what the minimum line is there for.

    Has anybody tried the new Mojave Shock from Procycle..........probably not as they've only just started selling them.

    I spoke to their staff and I'm slightly confused about what the Mojave Shock offers. Staff member said it only has damping control but no compression but has Cogent's new internals (shaft etc all new). Where as the exchanged one (if I sent my stock shock to cogent) has damping and compression. :huh To tell you the truth, I don't understand the two and maybe confusing myself. :1drink

    Anyway, I'm sure the Mojave has to be an improvement over stock. :D

    The Mojave shock has adjustable rebound damping but the compression damping is fixed. There is no prevision to adjust the compression but it could be changed by altering the valve shim stack. This is pretty common for non-reservoir shocks as there is no place to actually put the compression adjuster. The internals are the same as Cogent's 'shock shaft assembly". It's the same stuff that Cogent puts inside their reworked shocks (which ProCycle has also).

    This week I'm picking up a 2008 DR650 which is stock. I'm sure I'll be doing plenty of "improvements" over time to prepare it for my adventures. Until then I'd like to do whatever is needed to prevent getting stuck or blowing up the engine. This is my first priority.

    What I think I know:
    Neutral position switch loctite? Where?
    Chain roller removal...why?
    Fuel tap change? To what? Why?
    Neutral safety switches?

    Can I get some clarity on the above and whatever really matters that I don't know?

    Thanks!

    Relax, unless you ride the DR like a 125cc motocrosser, you'll never hurt it. :D

    Same thing. All you'll ever need to know about the NSU.

    I dunno, still using my stock vacuum petcock at 45,314 miles. There is just no way that I'm going to remember to turn the petcock off every time I park the bike for the night.

    It's almost summer here, there's nothing more important. :deal

    MBD, that just about covers it. :clap

    I'll actually have to be conscious of my rpms. All my rides so far were 250cc or less and flogging has become S.O.P. for me.:deal

    Guys,

    I just finished rebuilding the top end of my '98 DR650, and I have this weird carb/jetting(?) issue I can't seem to find an explanation for: when the bike is warmed up, after idling for more than a minute, for example when waiting at a stop light the engine has an hesitation or sometimes just stalls as I try to take off or even blip the throttle in neutral. Sounds to me like running too rich at idle (am I right?). It happens ONLY if the bike idled for some amount of time, like a few minutes. It doesn't happen if it only idled for a few seconds.

    I am using the stock BST40 carb with stock components, here is a list of the components I recently replaced (all with brand new stock, OEM parts):
    - ALL orings
    - pilot jet
    - needle jet
    - jet needle (6F19)
    - plastic spacer under the needle E-ring
    - diaphragm
    - throttle valve (slide)
    - throttle valve guide (with equiv. KTM part, as Suzuki doesn't seem to sell this separately)
    - pilot screw (currently set to 1.5 turns out)
    - fuel enrichener ("choke") plunger

    The OEM Mikuni #140 main jet is installed ( I did not replace this one) and also I have a new OEM pilot air jet but I wasn't able to get the current one unscrewed from the carb body, it's stuck and seems to just break instead of coming out.
    The needle E-ring is installed in the 3rd (standard) position.
    I'm using a GSXR 40F0 pipe, with the stock exhaust header, and stock un-cut airbox, the snorkel is also installed. The air filter is a K&N, just cleaned and re-oiled.


    Given the carb is clean and float height adjusted properly, what could cause this rich running at idle? I mean in the stock form, the DR650 is known to run a little bit lean. What strikes me is that even with my bone-stock configuration (apart from the exhaust) I have a rich condition and don't understand why... I'm running out of ideas... any help or suggestions would be highly appreciated. :scratch

    LE. if it matters, we can't get pure gasoline here in Europe. All gas we can get has at least 5% ethanol.

    I had a similar issue with my BST40 that I chased unsuccessfully by leaning off the pilot. Fixed it with an FCR. Upon subsequent reflection, I decided it may have been a fuel enrichener aka choke problem. Maybe?

    I was thinking about the enrichener as well, that's why I replaced the plunger.
    Another thing I omitted to say is I'm using the IMS tank with the locking gas cap. Often when I take off the cap, I can hear the hissing sound and see the tank collapse a little bit, as the pressure is released. Maybe this pressure that builds up in the tank can affect the mixture as well?

    Is there any down side to completely removing the neutral switch? I have ridden dirt bikes my whole life and dont need a switch to tell me its in gear or not.:lol3

    Does anybody know what size of bolts the Acerbis handguards use to clamp on to the handlebars? I apparently lost all four of the bolts and I need to replace them before my ride this weekend.
