    Adjust Carbs XL 1200 LT

    I've been searching the forum for information on adjusting carbs on my 99 XL 1200 LTD. I'm planning on rebuilding the stock carbs and was reading that it's best to remove the tamp caps and clean\inspect the high and low speed jets. My concern is how will I be able to properly adjust these since they are buried under the exhaust?

    Also my engine blew so I'm concerned the carbs were too lean. Should I rejet with the intent to protect the engine or are the stock jets ok. My ski is 100 % stock minus the D-Plate.

    If your ski is stock, don't bother. It's not worth the work involved. If you plan on modding and going with T handles, do a search on how to install them. Los of info.

    I just dismantled all three carbs and have a question.

    Lets say the jackass that previously rebuilt the carbs put the diaphragm assembly on backwards.

    I'm sure it's not good but how would that impact the engine.

    The ski had 130 hrs on it and it seemed to perform pretty well up until my pistons blew.

    The carb that had the diaphragm on upside down also happened to be on the same cylinder that had the bad piston.

    Thoughts?

    Not sure, I bought the ski with 126 hours on it and I think I put maybe 15 hours on it. They were pretty clean inside though. Internal filters were pristine, not a spec of crud.
