Pros and Cons of 1200 GPR
Just picked up my 1998 XPL about found out how delicate the 951 engine is.
Mechanic suggested the Yama 1200 GPR. I know nothing about them. I need to know pros and cons.

a disadvantage would be storage space, when wanting to ride 2 up, for the day or whatever

The one gripe I have about a stock GPR is the holeshot is god awful.
Pros: HULL, HULL, HULL, and did I say HULL

Some pesky cons on a stock boat, but can be remedied easily:
OEM Powervalve retainers (slip out and cause valve to drop)
fix: Waveeater clips
Wide Seat (ergonomic issue)
fix: get use to it
CAT CON (can crumble and break apart in exhaust)
fix: D-plate or O-plate
Holeshot (kinda weak and sluggy)
fix: Jetworks Mod holeshot kit
Intake grate; Dangerous (can cause pump overstuffing and danger when letting off throttle at (W.O.T.)
fix: Aftermarket grate
Factory RPM reading (inaccurate bar graph display)
fix: Aftermarket tach; i.e.) Pet-2100 / Tiny Tach comm.
Fuel Flapper Door/Screen (can casue fuel flow to get restricted)
fix: remove it
Oil injection Lines after 4-5 years (can slip off and seize motor "lack of lubrication")
fix: Remove and go Premix or install new lines
YPVS Servo Motor failures (electrical failure)
fix: replace or go gas valve
Great Handling Hull; very predictable
Easy to work on
Affordable Vs. 4-stroke
Parts still available and in abundance
Upgrade to 1300 easy
Lots of room for horsepower improvement & performance
Lots of technical support for this platform on this forum.
* I know the cons outweight the pros on my list, but don't take this literally, the cons can be easily fixed and this can be a very reliable machine !!
