Had a search but cant seem to find anything yet so if someone has asked this already then my apologies... When I start the VTR (its an 02 with 30,000kms) from cold it makes like a clicking or a ticking noise that builds with the revs. The clicks stay around until the engine is quite hot/warm ie: if I warm it with the choke for 5 mins or so in the morning it will still make it but after the warmup and the 10 minute fang to work the noise is gone. After the noise is gone, if I turn it off then turn it on a few minutes later the noise is still gone, so I figure its to do with heat? My old FZ750 and the RG's never made noises like this: is it a V-twin specific noise or just because my old bikes werent as advanced?
