Newb 2000 gtx

[davexdm9]

New owner here. Just bought a 2000 GTX . 80 hours on it compression tested 145-150. changed plugs . Question is what should I start with as far as tune up carb rebuild all that ?
Ski didnt get rode much last couple of years. First time out start idle good and then surged after half throttle . After a tank of fuel it came out of that and ran great for a couple of days . Now full throttle from idle it will stuble for a few seconds and then take off . Top speed also effected now . I see that almost all the tempo hose has been changed except for one hose i can see just in front of the carbs. So where do i start fellas. Thanks in advance.

First what model of GTX do you have? Carbed 951, DI 951 or the RFI 787?

Sorry 951 carb

Then yes, full carb rebuild using only Genuine Mikuni parts, new fuel selector, fuel strainer o-ring and replace the gray fuel lines but your's might have had the better black hoses from the fact

A stock carb'ed 951 should only have about 130 psi on compression test. Unless some one has cut the head down and installed aftermarket flame arrestors and rejet. 2000 and 2001 has grey tempo lines. 2002 started back with black fuel lines.
