Ask the same question again (as with handlebars) because some have answered to it I try again a larger circle with the topic of tooth belt squeaking. Unfortunately, with my Thunderbird some of the timing belts squeaks mostly at slow speeds 40-30-…Km/h. Have already asked at Triumph but not yet received a solution, if you know one? I know the silicone or oil is definitely not a solution, so the sense of the maintenance arm toothing goes I don’t know how the ingredients react with the belt material. I hope that the topic can now be found directly via the search engine. Who is interested can also look at the topic of handlebars because the topic of zanh strap squeaking was addressed for the first time. Best regards T-BirdYP5
