    Taking out 66v engine, what do i need to know?

    I've done tons of work on the 65U engines in the older gp1200's but my buddy has a 1200 XLT with the newer powervalve engine. His stator side cylinder has no compression so I'm gonna pull the engines and have the top end done. My question is, what are the steps to removing this compared to the 65U engines? I'd imagine the are very similar. 1st I would think you need to pull that huge exhaust off. I've never dealt with power valves, what do I need to do to take the linkage off of them (cables)? It is important to keep those 2 adjustment nuts in the same place, or is it easily adjustable when I re install it? Do the carbs need to come off before I can lift it out? Anything else? I do have a service manual also! Thanks a bunch,

    Eric

Remove the bracket from the PTO cylinder. Dont mess with the cables. It is important to keep those 2 adjustment nuts in the same place, or is it easily adjustable when I re install it? You wont have to worry about this is you just take the bracket off. Do the carbs need to come off before I can lift it out? It is easier if you take 'em off. Anything else? Its pretty straight forward.I do have a service manual also! Thanks a bunch,

    Question ????????

    Hey Eric..

    If you're only dealing with the one cylinder..??

    It'd probaly be easier to just do it in place..??

    Have you assertained the amount of damage yet..??

    By NO compression do you mean zero..???

    Most time's a good used piston and jug will put this machine right..!!

    Will save a ton of time/swearing taking the carbs on/off..!!!

    Gerry...
