    Top speed for XLT1200

    What should the top speed be for a XLT 1200 running stock? Compression on all cylinders 120-125 psi. Is this about the right compression for this motor. Reading taken on cold ski. D-plat mode installed.

    One should always take compression reading with the motor at operating tempture and the throttle wide open. Otherwise you will not have accurate readings.

    My experience is similar to Chip's ... my 1999 XLT ran 58 - 59 mph stock. I had GroupK cut the stock head for a little more compression, put in a D plate, free flow in the exhaust, a GroupK cut stock ride plate and a Solas 12/18 and R&D (or Riva) intake grate. Setup that way it would run 63 - 63 mph GPS with VERY good holeshot for a big ski. Great hull, seat and steering on that ski, I still miss it ...

    Thumbs up Check it out...

    Hey dude, ok check this out... I've tested my XLT on several conditions. Top speed on 120psi compression on my ski (100% stock) GPS'd 57,58 & 59 on a REEEEEALLY perfect day & I could barely hold 59. I've spoken to several XLT owners & they state the exact same thing. Now, I just installed the R&D intake grate & ride plate & I went out to test it yesterday & under choppy conditions I GPS'd 58,59. Never got 60 but I know under better conditions it should get that very low part of that number 60! hehe. I'm workin on it.
