Yes those boxers are nice for that....the 950 were supposably checked at the first service...tell you the thruth ,I don't believe they even done it now, by the amount of time the bike was in the shop...lol....
It's something now I diffetnly check into...looked at a few videos and that valve service on the triumph don't look to complicate at all...not much stuff to remove or required any special tools...it has rocker arms...unlike the ktm engine we're the cam is sitting directly on the bucket shim..needing to remove cams for any shims swop out...
