Turn signal switch with P/N61318048152AM will only fit with switch support with P/N32722072175. The original Magura switch support is too high, so the switch does not connect properly to the switch support. This leaves an opening visible.                              

Without direct comparison, it can be difficult to distinguish the difference between the R25-R25/2, R26 and R27 exhaust pipes. This photo shows how you can easily determine the type of exhaust pipe:   The R25, R25/2 exhaust pipe is significantly longer at the straight end than the R26 exhaust pipe:

For unknown reasons, the supplier of the after-market throttle assemblies for the R51/3 – R68 models (pn 32722072350), has decided the modify the design of the sliding block. The old sliding block used to have recesses to hold the cable ends, the new version does not. While in the new version the cables cannot “escape” either, the cable ends can rub against the inside of the throttle body causing unwanted wear. We therefore remove the new sliding block from the throttle assembly and add the correctly designed older sliding block. This however increases the price of the throttle assembly.

There is a clear length difference between the side stands for the R50 – R69S models and the R50US, R60US and R69US models (due to different configurations of the front fork) These are therefore not interchangeable.

The width of rims can be measured in 2 different ways: the inside or the outside. This means that one and the same rim can be indicated both in (for example) 2.15 “and 3.08″ WM2: inside 1.85″ (47 mm) outside 2.72″ (69 mm) WM3: inside 2.15″ (55 mm) outside 3.08” (78.2 mm)

There are 2 versions available in the market. The one on the right has a lower push button housing. The hole in the housing does not align with the hole in the connector, as a result the wire cannot be connected properly.

BING jets are stamped with numbers, such as 35, 40 (idle jets) and 110, 115, 120 etc (main jets). One would expect that these numbers refer to the diameter of the jet bore, however this is not the case. This is confimed by the company BING in Germany. A few examples of main jets measured with a wire / jet gauge: BING 44-051 main jet 130 = gauge 120 (= 1.2 mm) main jet 125 = gauge 110 (= 1.1 mm) main jet 120 = gauge 105 (= 1.05 mm) main jet 110 = gauge 95 (=0.95 mm)
