Worked for me. My left grip was intermittent. it looked ok. But I resoldered both joints and it works fine. I replaced the grips with aftermarket ones. nice soft dirtbike ones. I purchased 2 sets and used both RH grips. Used hair spray to glue them on. Super glue at the ends to seal. Then a little silicon to make sure no water gets onto the grip.
I was a bit worried at first that the new ones were a bit thick. But they warmed my hands up fine. Will try them in the cold in a couple of weeks when I head south.
