Title: Poor Performance
Post by: pjcroziersmith on October 06, 2011, 03:37:39 AM

I had my Vitality 50 4T in for the 3000Km maintenance.  Before the maintenance I could get 55km/hr (35mph approx) on the flat, but since I can't get more than 40Km/hr (25mph approx) on the flat.  The mechanic says there is nothing wrong with the scooter and that is the way it is supposed to run.  He has had it for a month and claims he can not get it any better, personally I don't think he even looked at it since.  He still maintains that the scooter runs perfectly.  Anyone got any suggestions?

Did he adjust the valves gaps ? Maybe he didnt set it correct?

Just a suggestion.

That is a good possibility on why the power is low.
If the valves were tightened a little too much, the compression
will be a scratch low because of blowby on the valves. at least
have it checked soon before you burn a valve.
 good luck, Kymcorider

Thanks for the suggestion, I will have to have a look at them.  At least I have all winter to get it running properly as I do not ride during the winter.
