i have a Yamaha vx110 it have only got like 39hrs on it. last year i took it out and it would run about 65mph. i took it out on sunday and it wouldnt run over 34mph in the L-mode or normal-mode. the rpms are at 6,800 and wont go over it in ether mode. when out of the water it will rev higher. anyone have a clue,

I'm having exactly the same problem with my VX110 Deluxe.
Anyone have any suggestions?

i figured out the problom. i pulled the plugs out and they looked very bad. the funny thing is that it ran fine.no skip idle fine. went to advanced auto parts and they matched them up with new ngk plug. put them in went to the dock and put it in and soon as u started to take out you thought you was on a new ski. let me know what you find out on yours

Sometimes too much oil causes this. Also, air filter gets oily and dirty sometimes.
