Spark plug life & failure

Featured Replies

My new plug worked fine on Saturday and so had a few hours practice.  All good - starting OK, no issues.  Many thanks again to everyone for the advice.  I will get the carb checked over and make sure the tuning/jetting is in accordance with the TRS published spec.

I have been finding that the plug cap is the problem, never had to replace a single plug through the 5 or 6 TRRS bikes that I have owned. I think that the act of changing a plug helps with the connection, making it appear that the plug change has fixed the problem, when it will only reappear in the near future.
