So my Hobbit runs great. Pulls hard and feels strong, but somewhere between 40 and 45mph, something in my transmission is letting go. Engine revs way up and I feel the belt hook back up when I let off the throttle.
Setup is a TJT, DOS race gears, DOS ramp plate, polini kit, Vforce reeds, oko 24, calibrata pipe,
I've tried every belt and tension setting you can come up with, currently running an OEM replacement from treats.
I've tried two different rear pulleys, one of them with a yellow contra from treats. The only change there was the same belt slip at a lower speed, ~40mph on the yellow spring, ~45mph on stock.
I have two working theories.
1. TJT pulley cheek is slightly larger than the cheek on the clutch bell side. Maybe the TJT is carrying the belt past the point it can grip the inner cheek?
2. "Pedal mode" spring is being compressed by a lateral force introduced to the gearbox by the new straight-cut race gears. Or just sheer brapp.
So has anyone had this problem?
I've got a spacer to replace the pedal mode spring, and I just ordered a new polini Camino variator from Belgium. So if it's either of those, I'll get it. I hope.
Now please tell me why I'm stupid and none of this will ever work.
