VIFFR Posted January 9, 2015 Share Posted January 9, 2015 99 5th Gen that has 70,000 kms. I did the valve clearances at 50k and whilst some are our of spec it wasn't by much. Today I started it (its about 38c outside). And there was a rhythmic taping. Tap tap tap. Sounds like it could be a valve issue. I can't hear it over the cam whine/ exhaust note off idle. Any ideas fellas? Thanks! Link to comment Share on other sites More sharing options...
fabio222 Posted January 9, 2015 Share Posted January 9, 2015 I'd have guessed valve issue too although I'd hope not seeing as you did them recently enough. Link to comment Share on other sites More sharing options...
VIFFR Posted January 9, 2015 Author Share Posted January 9, 2015 More info. It's about 2 traps a second. No performance issues. I thought it may be injectors needing cleaning. I'd have guessed valve issue too although I'd hope not seeing as you did them recently enough.I made sure that when I did them, if the spec was .22 +/- .02 that I set them to .22Not correct figures, but you get the idea. Before I adjusted them the was no issue with noise. I had the bike apart so I thought I'd do them. Link to comment Share on other sites More sharing options...
fabio222 Posted January 9, 2015 Share Posted January 9, 2015 Maybe try clean the injectors and balance the throttle bodies? Link to comment Share on other sites More sharing options...
VIFFR Posted January 9, 2015 Author Share Posted January 9, 2015 Maybe try clean the injectors and balance the throttle bodies?I'll do that thanks. I noticed when I started the bike after lunch (bike was at 68c) the ticking had gone. I'll put some injector cleaner in the tank and give it an Italian tune up this weekend. I'll do the throttle bodies next weekend when I'm home. Thanks :) Link to comment Share on other sites More sharing options...
fabio222 Posted January 9, 2015 Share Posted January 9, 2015 The temperature difference wood alert me to valves again. This is a strange one. Try cleaning and balancing the throttle bodies anyway, I think they're meant to be synced up after valve jobs anyway (at least on carbs...tie supposed to balance the carbs after doing valves). Best of luck, let us know how it goes! Link to comment Share on other sites More sharing options...
AllWeather Posted January 10, 2015 Share Posted January 10, 2015 If it is only doing this from cold it could be blowing exhaust gaskets either on the head / pipe interface or the coupler of the 2 pipes at the rear Link to comment Share on other sites More sharing options...
VIFFR Posted January 13, 2015 Author Share Posted January 13, 2015 Well the noise has stopped. I've run it 3 times since then and there has been no nosie at all. Spoke to a mechanic who said it could be an injector. It's coming apart for a major service in the next few weeks so I'll see what I can get done in a weekend and go from there. Thanks for all your input so far. Link to comment Share on other sites More sharing options...
