    How to take a Modded Ultra 150 back to Stock

    I have a 2000 Ultra 150 (JH1200A) with a number of mods, all listed below from original owner's invoices.

    I wish to tear the engine down and put it back to stock. All H.P. modded parts are available for trade/exchange/etc. for high quality stock parts. Please P.M. me if interested in swapping.

    I am interested in getting your help on the steps to go through and the parts to replace to get my machine back to a reliable/dependable/stable stock condition. Thanks.

    MODS

    Below is a list of all invoice data that the original owner gave to me at time of purchase. It seems that all mods were done in the first summer of ownership. And having talked to the seller/owner - he was very proud of his machine and all it could do. I bought it in April 2010 -- 10 years after original purchase. It had 91 hours on it when I bought. So you will see that he did a compression test in 2006 at 85 hours.

    trade out the exhaust pipe and stinger, carbs [ complete rekit if questionable ] and air filters & cyl head for all stock, ride plate, impeller and grate should be ok, stick with a good quaility tcw 3, be cautious of water in fuel, run and pop the throttle several times when removed from water, store the bike with the rear tilted down, use stabil in off season and run periodically.

I should have all the hardware for the airbox also. I am in HI right now till the 15 and should be able to round it up when I get back.
