Hi everyone. I’ve been a Ski Doo and Can Am guy for a long time. I’m now the owner of two 951 Seadoo’s. The one in question is a 2001 Gtx. I bought the ski in rough shape not running. Over the winter I restored the entire ski. Spared no expense. The 951 has a new WSM crank, wossner 88 mm pistons, new fuel lines, oil lines. Rebuilt the carbs, After a forever wait getting a crank for this due to Covid I finally got it running. So here is the issue. Starts and idles great. Has a bit of a bog from 1/4 throttle if u are slow to accelerate. I’m going to adjust the low speed screws for this. The main issue is it only hits 5700 rpm. Pretty much from 1/2 throttle up it just changes the tone of the engine. If I pin it from a stop it pulls hard, will flash to 6200 then drop to 5700. I checked the water valve and Raves. I ran it with the caps off and made no difference on top. It made the bottom end worse but that’s to be expected. If I add choke at full throttle it quickly starts missing so it seems fuel supply is ok. Plugs look chocolate brown. I’ve spent lots of time searching and trying things people on here have done. I have not been able to verify the tps adjustment. I’m having issues finding the pin out for the Mpem as I can’t reach the sensor connection to test there. I’ve heard conflicting info about how much the tps effects the carbs engines. The engine sounds flat at higher throttle if you know what I mean.
