VTX1800 Valve Adjust - Always Noisey
I`ve got 24K on my odo, had the bike since new in 2002. Have adjusted the valve clearances 3 times (once every 8K). Apart from the fact its the worst bloody fiddly job I hate doing, I was always frustrated that even after hours of careful adjustment, the valves were always noisey, ticking and tapping...especially at idle. Finally consulted my dealer who told me to make sure I adjust the clearances to the low side of the tolerance for each gap, i.e, make them on the tight side. I did and it made bugger all difference. Still noisey. Its just a VTX thing. Mechanical tappets are 1920's technology....
As for the predominant ticking, yes, thats the decompression valve. Nothing to be done there. Its just a noisey engine...although mine does sound like a bag of nails.
As for the backfire, I have V&H bigshots and PCIII with K&N filter. Always runs a bit rich and at "neutral" throttle, she pops and bangs like a pissed off dragon. Nothing I can do about that either...its just a VTX thing.
