Finally got around to service the Jonway. Been winter in South Africa I picked a lovely day all of 20 degrees C (about 12f)which is a rather warm day for winter. I replaced the rollers as I couldn't find sliders. The old ones were 21 grams and so was the new ones so I didn't expect a gear ratio change. The old rollers were slightly flat spotted and the kitchen scale indicated 21g for all. But after the service and the first pull off I noticed a sluggish scooter, until I hit the open road. Where normally I would do almost 6000rpm at 70mph here I was doing 5400 rpm at 75mph. So even though the scale indicated 21g each, the scale is what it is made for slimmers diets and not so accurate, the old ones obviously were slightly lighter through use. I can live with pulling off in "2nd" because after that the scoot pulls nice and strong.
