There is a known issue with he engines in these motorcycles where the bolt for the timing chain tensioner comes loose and causes excessive wear in the timing chain guid with causes the timing chain tensioner to come apart inside of the engine which will cause the engine to have to be replaced due to loose metal fragments in the engine. I went to my local dealer yesterday 12/27/2025 to talk to them about my issues and one of the mechanics pulled me back too look at a bike with the same issue and the engines was completely disassembled so they can fix it.
