    Will do chap, it should arrive next week.

    Iv'e made a 41mm Keihin FCR from a CRF 450 fit the bike and it works quite well but a pain to get the jetting right. I made an alloy insert to reduce the carb to 32mm and cut away some of the top of the throttle cable housing to get it to fit and used a pull cable only. bit of a job but it ran well and revved to the moon plus no Honda kill switch effect! but the Edelbrock should be a better fit and easier to dial in..

    Its an Edelbrock QuickSilver 2 carb. Edelbrock part number #3116 bore size is 30mm wide x 32mm tall. They are discontinued now but do crop up from time to time. They have no jets and are easily adjusted externally, you just swap out the needles to get the right baseline setting then tweak the adjusters to suit your bike/altitude/air temp etc..

    I have the eddie for the XR250. Love it! Bike feels like it runs much better. Starts first kick, easily (as long as idle adjuster is in right position). Did that with the air box mod, and bike really cruises.

    Love that white tank for the 250. Wonder if it'd fit a 2000? :evil

    If it's got a compression release I'd look at that. Over here, some of the bikes have automatic compression releases, and I've heard of people disabling them because of problems.
    It is full of oil, right? How many miles? Valves been adjusted?

    that page does not give any prices and
    smallest carb they seem to offer is a 36

    or can someone less left-thumbed when it comes to computers
    please post which will fit an XR250




    next issue
    I am looking for a rear shock for an 86
    what all is plug and play?
    does anyone have a working shock too many
    and is willing to part with it a reasonable price?
    thanks

    It has a auto compression cable, and yes :-) I check my oil level religiously. Bike's quite old, just to give you an idea, the oddometer stopped working at about 78k km :eek1 . Valves were adjusted recently but I'll take it to the mech and check them out. Thanks

    I think I have one that is complete that came off an 87. It has an aftermarket spring on it and doesn't have any leakage. I can't make any promises as to what kind of shape it's in internally however. I can double check later but if you want it I'll send it to you for 40$

    Could very well be a worn out cam chain.

    Stanless steel is non-magnetic I believe. I know the magnets don't stick to my stainless fridge. My wife wondered why I wanted stainless, I said you'll see... :evil

    She still managed to hang a dry erase board.... :bluduh

    Well folks the Edelbrock carb was modified to fit today and the bike started after three kicks, a little adjustment to the accelerator pump and idle speed and it seems spot on! The pita Honda kill switch bogging issue is now history and I have a very snappy throttle and a marked increase in power right across the rev range, and very smooth power delivery..

    The Carb is a 32mm version and was for a Hardly Worthitson not a proper XR kit, but an hour in the lathe and it fits pretty dam good using an XR400 airbox boot. I will get some photos up when I get some time to take some in daylight, next mod is the 2006 CRF250 front forks..:wink::wink:

    And now with the forks fitted!!!
