    Question 2006 Vx110 Help! Engine revs all the way to 8000 but tops out at 35mph

    Ok this is my first time posting so bear with me, I bought a 2006 Yamaha vx110, I took it out to the lake last week and no issues, then I take it out this week and it will rev all the way up but will not go more than 35-37 mph. I pulled the air filter and it was clean, no oil in the air box, I checked the plugs, they were still good but I changed them anyway, and I pulled the pump off to inspect the impeller and wear ring. Both looked fine but I will post pictures fir second opinions. I canít figure out why it wonít go over 35. Any help is appreciated

    Heres some more pictures, I noticed the white spots in the pump but non of those spots are actually on the wear ring in front of it, it has a few scratches but when I rub my finger around it I canít feel it, itís still smooth inside

    You need to check the clearance between the impeller and the wear ring, I think .014" is max. The white spots are normal, just salt deposits on the alum stator housing.

    .014-.018 inch is normal clearance. .024 inch is max. Impeller has a few nicks and the pump liner looks like it's a little sanded. I bet your clearance is the main problem.

    The clearance is about .023, so that bit of clearance issue would cause a 20mph drop in performance?
