i put about 20 break in miles on my moby the other day and it was running great. I had some minor issues with the varplus and figured others could help. ive done plenty of reading on these things, and have some experience, so im not completely in the dark to some of the tricks of the trade.
basically the thing feels great and smooth, really flings me right up to speed. although it took me a while to realize that going from about 3/4 throttle to WOT made no difference. it was because my varplus was not opening all the way, as they tend to do so frequently, and not letting me into my highest gear.
it is also apparent that its not opening fully because there is a rubber ring around the sliding cheek from where the belt finds its final resting place. the belt hangs out in the same spot for too long, with the cheek trying to open further but instead it just rubs belt rubber off onto the cheek.
every now and then something would happen and allow the varplus to keep opening... sometimes a quick burst of WOT would get me up there, sometimes going down a hill (although that didnt help as much as i figured it would). this would allow me to reach the highest gear and DAMN what a huge difference it makes. im talking 6-7 mph im losing out on.
i want to know what needs to be done, _assuming_ its all together properly (i believe it is), to get this thing to function properly all the time.
as for the specs of my bike, its a ported 50cc cylinder from QK (technix brand), matched, 14.12 sha, G3, and im running the lightest weights. oh, and im running teflon based spray lubricant as specified in the french instructions.
two things i can see affecting the varplus' ability to open fully are belt tension (and therefore return spring tension), and roller weights. If I put in a bigger set of weights (maybe even half mids, half lights), will that allow me to get into that higher gear? What if I weaken the engine return spring by bending it in a little?... i feel like if that is weaker it will make it easier for the engine to variate.
thanks for reading.
