Higher Revs Initially

Recently the scoot has had a strange condition. From cold when setting off the engine has to use higher revs for about the fist 3/4 mile or so. I'm talking 6000 revs to maintain a speed (indicated) of 40 mph. Then after that the revs drop to normal, 6000 revs would cruise the scoot at around 70 mph.
It can't be the belt as it that was worn then the revs to speed ratio would remain constant. My thoughts are that the variator pins are sticking (JCosta). Has anyone else had this and did a good cleaning and dry lubrication solve the problem. Looks like it is a half day in the garage checking it out - now where did I put that 8mm socket?
Any thoughts appreciated.
Cheers,

I seen variator pins ware out on the tips leading me to believe that the constant rubbing and heat friction would cause some bits to stick on the moving part of the variator plate. A problem that [ JCosta] have .

Hello,

Looks like I'm checking the wear levels on the pins next week.

Found this site, is 16 gram the correct weight for the Silverwing or do I have to get the kitchen scales out?

I might be wrong but dont j.costa have a office in Warrington??

Hello Mark,
Searching the web they don't appear to have anything in the UK, even their UK website doesn't exist anymore.
Ordered 15.5 gram pins from Germany. Will get a new belt at fit that at the same time, keep the current one for spare - carry it with me on long trips.

Cheers,

could put the honda variator you have back in and take it for a spin to see if the revs become constant to prove your jcosta pins theory

Just my opinion the JCosta has 12 pin .The Honda variator has 6 rollers, 28grams x 6 =168 grams, J costa !@ pins X 16 grams = 192 grams. That might make your Swing slugish. Your call.

Hello Tinman,

I think the new JCosta variator has only twelve pins, mine however has sixteen.
16 x 15.5 = 248.
As it is a totally different design it is difficult to compare the two accurately.
The JCosta is a competition item, it isn't really marketed as an everyday upgrade. However the performance of the Silverwing with one is far better than a stock scooter or one with 26 gram DP Sliders in it. I tried it. Plus the scooter has less vibration which even if it gives a lower miles per gallon return the comfort factor makes up for it.
Off to my local Honda stealer tomorrow to order a new belt.
Cheers,
