Tim D. Posted December 20, 2014 Report Share Posted December 20, 2014 Hi Chaps, So have taken the head of the engine and extracted the tappets and camshaft... As I suspected there was some serious pitting (had seen some by looking up while doing the bearings).. 3 of the lobes had worn sigfnicantly.. Wouldn't have done much for valve opening.. Cam had done about 40K miles and was a triumph tune item.. Also found that the pads of the rockers that act on the valves were V worn.. Again would reduce valve opening (impossible to set gaps properly!).. Cheers Tim Quote Link to post Share on other sites
Peter Cobbold Posted December 20, 2014 Report Share Posted December 20, 2014 Tim. Never mind just wind up the boost a bit more to compensate !!!!! Peter -only joking Quote Link to post Share on other sites
RogerH Posted December 20, 2014 Report Share Posted December 20, 2014 Hi Tim, what valve springs do you use. Many people put uprated springs in and then go touring. Cam wears out. Use standard springs they will work up to 5K with no problems. Roger Quote Link to post Share on other sites
Tim D. Posted December 20, 2014 Author Report Share Posted December 20, 2014 No idea what was in there. But using standard now. Tim Quote Link to post Share on other sites
