We have seen several examples that the pressure build-up blows out the gasket. The pressure could also cause the crankcase seal to blow. Either is a potential for a failure of the stator windings and pulser coil. A simple solution to this pressurization problem is to vent the magneto case. The tubing is inserted through the magneto case grommet at one end and into the air box at the other end.
Installation takes about ten minutes.
We have been working on this development for the past 3-4 years. A lot of testing has gone into the development. We are very close to having this product line available for sale. The balls are pre-inflated to the desired pressure prior to mounting the tire. Mounting of the tire is similar to mounting a tire when using a foam tube insert.
