    gp1200r make it go faster need help ?????

    ok so ive decided that im not guna bother buying another ski and do a four stroke engine conversion i will just spend money on my 66v engine to make it go harder since i mainly ride my ski in the surf but i still want it to go half decent wen im on flat water. Need ideas on what to do like should i just sell my ski and buy a 1300, change the top end to a 1300 , buy a stroker engine someone give me some ideas on what i should just do instead of me stuff assing around

    A Lot of bolt ons you can do to the 1200 and will make it run great. Do some searches on here. First mods should be- reinforce tunnel, intake grate for hook up and safety. Rejet the carbs and flame arrestors, modded rideplate, prop, heads, keyway, V-force reeds ect.....

    Just depends on how much money you have to spend and your skills. A well setup 1200 can go 75mph+ Add a 1300 topend, even unported can go upper 70's. Been there and done most all setups before.

    Its much easier to reinforce it, than for it blow out and sink your ski. here is the link- http://www.greenhulk.net/forums/showthread.php?t=7240

    Here is the link for carbs- http://www.greenhulk.net/forums/showthread.php?t=70129

    If your riding on smooth water and need more speed- the r&d rideplate can be modded for more angle and increased speed, just depends on your conditions and what your after.

    How much do you want to spend? Kevin "water woody" might just sell his whole big bore stroked tripple pipe set up. Over 86 mph at 4,200'.

    He can even port your cylinders and make it a big bore engine. Www.wcporting.
