I have also posted this on a few other motocross forums in the hope that people will be aware of the dangers.
This will not apply to the majority of bikes used on here as they will probably still use the O.E. one. The original Gunnar Gasser throttle is a quality piece of kit that has been around for a long time. It is a shame that the cheap chinese copies available (mainly through ebay) are not.
I had an issue at the weekend with a Gasser copy. These are the ones with the BLACK cover and does NOT have "Made in Sweden" cast into the body. The plastic tangs on the throttle tube the hold the cable WILL break off sooner or later. Mine did on Sunday afternoon. Luckily the throttle was being closed at the time. It usually happens as you're opening it or WFO. It looks like it is caused by the tangs and plasic cover being moulded badly. It lets the throttle go past the "stop" when closing. This puts strain on the weak (read cheap crap) plastic. A small piece will eventually break off jamming the throttle.
I contacted the ebay seller that I bought the unit from yesterday. Had an email back from him today genuinely concerned about the problem. This is good. But there are a great deal of people selling these who don't know how dangerous they are, or do, and don't care.
I must stress that the good ones have a grey plastic top cover, and "Made in Sweden" cast into the body.
This ONLY applies to the "Gunnar Gasser" style of assembly. No other style (including the Venhill one) has this problem.
