v00d00child Posted August 15, 2004 Share Posted August 15, 2004 A month or two ago, I noticed a clicking noise coming from the upper LH side of my engine. All RPM's, no noticeable performance hit, mileage is fine, not drinking oil. Someone on sport-touring.net posted a problem about a similar noise on a vtev vfr, and said a bearing had shelled, and the cam was bashing the journal. Total engine rebuild in order. I know they're totally different valvetrains, but me, being a fatalist, had to have some gloom. Enter PAIR valve discussion: just turned her over to 34K last week (she's a 97). Read the posts on PAIR valves, which as far as I can tell, do nothing but give tree-huggers warm fuzzies. If I managed to snap a PAIR valve, would it cause symptoms (noise, mainly) that I have???

Northman Posted August 15, 2004 Share Posted August 15, 2004 It's a possibility, but a loose valve is more likely, by the way you're describing the sound. Have the valve clearances ever been checked? Quote Link to comment Share on other sites More sharing options...
Red J Posted August 15, 2004 Share Posted August 15, 2004 Voodoo, I've removed my pair valves. If you want, they're yours for the cost of shipping ($3). They're used, and dirty, but they're not broken. Have you verified that your's are broken? If you want to defeat the pair system, I can help you out there as well. Let me know. J.

Since, assuming normal wear, valve clearances should only decrease, isn't a loose valve an indicator that something's awry??? (here's goes the doom & gloom tendencies again...) I'll probably run her into a shop in Sept to get her serviced. Quote Link to comment Share on other sites More sharing options...

Yes, but you may be causing further damage by not checking them... :???: I'd pull the tank & airbox and start looking. The valve cover is a bit of a bitch to remove, but since your bike is carb'd, you should be able to run the engine without the tank to further diagnose.

Northman Posted August 15, 2004 Share Posted August 15, 2004 Just thought of something else... How about an exhaust leak on one of the primaries? :idea: Quote Link to comment Share on other sites More sharing options...
