rxp random flat spot
Was out with a few mates and took turn riding the ski,i was riding my mate rxp (stock) random rpm and throttle position the power just shuts off for a second and then pulls. Eg cruise at 4500 then wot it cuts out like the power shut off then comes back on power..any one encountered this situation and advice on where to look and test..

I have encountered that with bad injectors Which 48's do you have?.... feels like a hiccup, change sparkplugs..

I believe he said he was riding his mates stock rxp. I'd start by changing the plugs.

Fuel pickup, fuel pump, DESS post, are you getting the dreaded beep beep beep when this happens or just an engine surge or flat spot?

service was done 1hour ago...i dont think it is the injectors, wouldnt the ski run lumpy if a injector is faulty? this issue is the ski just feels like it switched it self off, then a second later power is up but everything on the dash is working and reading while the cut off..can faulty tps sensor course this to happen?

what was done in "the service done 1 hour ago"? -- what I am getting at is: WHAT WAS DONE INCORRECTLY... The local dealers around here can really screw up a good running machine-- when they perform general "service".
