    help! xl1200 ltd bogging down

    hello i have an xl1200ltd and it had a lot of cavitation due to a worn wear ring ,it would reach 80kph but with a lot of cavitation low down .
    sorted that problem with a new wear ring and impelor but now there is no cavitation it has trouble starting in the water and wont get past 50 kph
    its like there is a blockage in the exsust somewhere or like its towing a boat!,if i rev it in the water it hesitates and picks up realy realy slowly (no cavitation)
    here is what i have done ...
    checked compresion (cold with 2 plugs left in) #1 =118 #2 =115 #3 =110
    checked waterbox for blockage checked stinger for blockage (euro model with d plate fitted)
    starts fine on trailor and then with hose .
    i have also pulled fuel line of carbs and checked fuel and it looks fine.
    (drained tank from end of season and put fresh fuel in)
    also fresh plugs fitted .
    im a toatal novice but not afriad to have a go please help..
    cheers richard..

    help

    reading through other posts i think this could be a carb issue ?

    if it is (tell me if you dont agrea)
    how do i remove the second exhust the one on the manifold i cant seem to get a wrench near the inside bolt!
    ive mastered the stinger but i need that second bit off to get at the carbs.
    any how to's with pics on here i cant seem to find any.

    so only the stinger is removed to take of carb?
    and im guessing you just remove the airbox by the retaining clip?

    yes sounds like a carb issue, pm osidebill, he is the resident carb guru, yes you only need to remove the stinger, then un clip the air box cover & then the base of the air box bolts to the carbs

    thanks

    thanks for the reply
    i kind of got an idea where im going with this but if oside would give me some input id be most greatfull .
    one more question would spark plugs do this
    the reason i ask is i was useing fresh br8es plugs and they are set at 0.8mm and given i was cavitateing at the time of instaling them
    (i used a full tank of gas more or less in 1 hr)
    would it burn them plugs out real quick?
    i have just instaled another fresh set but this time i have gaped these to1.1mm and cavitation is no longer the issue also it seems a lot smoother on the trailor.
