Thread: Gp1200r

Hey everyone
Im new to this site and the ski world and have just bought a 2000 gp1200r with works intake grate ,soloas impeller 13/19 i think , r and d ride plate the motor have been rebuilt and has wisco pistions in it. I love the ski as it goes better than i thought it would. It has a top speed of 111 which i did on a fresh water dam is this a normal speed for this ski?
I have just pulled the motor down as one piston was at 95psi and the rest were at 100 psi, i found no signs of any probs so i have ordered a set of rings and wave eaters through steve as he has been great to deal with. If there is any hints or problems with these skis would be great to hear about them.
Cheers Matt

Solas 13/19 is the correct after market prop. for your ski.
Don't believe the 'dreamo' that shows your top speed.......It's wildly optimistic. 62/63 MPH or a genuine 100 KPH is nearer the mark for a stock GPR. Check it with a GPS for an accurate reading.

Compression is VERY low on your engine, yet you say it's rebuilt???????
It should be around 130psi and EVEN on all cylinders.
Perhaps new rings will cure it?????? Good luck.

Ok i will see with the gps, and yeah i hope the rings will raise the comp.

Be sure to de-glaze the bore, otherwise the new rings will not bed in.

Is there any sunshine coast riders on this forum would be good to go riding with some other skis

I have seen that the squirt thing out the back has been takin off is this normal should i put it back on?

yeah and a 5/8 plug that break every time i go out

Looks like it has had the cat removed and d plate installed as so diffrent exhaust pipe at rear. Thats maybe way i need ear plugs when riding it.
