The front pulleys and rear pulleys are still going through their ratio. This means on the flat land (motorways) the bike is held at 2500 rpm at approximately 60mph. I struggle to get past this unless downhill, and uphils drop this to mid 50's.
I theorised that if I can get the engine revs up, I should get more power, and retain that speed.
I used an laser tachometer and reflective tape on the rear wheel to measure its RPM.
at redline with the bike on the stand I had 1580 rpm which was roughly translated to 110mph ground speed. Obviously no good, bike hasn't got the power to achieve this, so I set about blocking the movement of the CVT pulleys to lower the "top" gear.
A 3d printed collar on the rear pulley, that looks like this:
This serves to limit the amount the rear pulley opens.
It goes here:
That is half done, After this we move the attention to the front pulley. With the setup as it is now, the front pulley will burn the belt out as it wants to go through its full range of movement, to solve that, we run the engine up to top rpm and mark on the pulley with a marker the belt position.
Then we print another shim to go on the stub axle and prevent the pulley from moving in all the way, therefore saving belt life!
I did 125 miles yesterday and initial results seem good. Bike can now do 70mph on flat at redline, and hills only slow this to 62-63. Fuel economy SHOULD be improved as well, as the governor is not overfueling the whole time, but I' on the fence on that one.
The rear one is plenty thick enough, but the front blocker is very thin and I do worry that it wont last, so will keep a close eye on it.
