Reply With QuoteVideo of the noise? I can hear my valve train over my jardine GP1, althought only at idle. Once revving you only hear exhaust.
Well my 04 XB12 is going to come apart at 3000 miles.
I know these things make noise but I shouldn't be able to hear the valve train over my Jardine.
The front cylinder taps like hell and chatters pretty damn loud at speed.
Thinking it may have a collapsed or stuck lifter or a bent pushrod or bad cam bushing. It was noisy when I purchased it but I just can't stand listening to it anymore and am afraid its going to bust or wear out more parts if I don't pull it apart now.
Going to rotate the engine and dig into it soon.
Any recomendations on lifters/tappets brands to replace them with?

Yeah, I hear valvetrain noise at idle, low revs over my Jardine RT1 all the time. I'm not terribly concerned. Only more noticeable now that I repacked with better packing.
I use earplugs.
Round 5g the noise turns into a nasty chatter wich there is no problem hearing over the exhaust.
I will try to get some video this weekend.
I was sort of ignoring it till I took it to get it inspected at the local non-dealer Harley shop and one of the mechanics walked out the door while it was running to see what engine was running with a collapsed lifter. He could hear it in the shop.
He said he has heard some noisy arse Sportster engines but something is not right in that engine.
They all know I do my own work so its not like he would be saying that to get some work.
Ah that makes some sense then, if the noise gets worse/louder as revs increase. Sucks for a low mileage engine. PO run it without fluids or use wrong (sheered) oil? eek
Crack open a cooler line, check for good flow, ASAP or right now before running it further.. then cut your filter open..puncture it & use tin snips, (no hacksaw).. see whats hiding between the pleats, it's the best 6$ diagnosis you could perform.. if all looks good you have a benign, relatively low-cost resolvable issue.. filings in filter, park it and start looking for parts.
Found my problem tonight. Front header is cracked at flange.
That's a common problem. Glad it was that easy.
Tig welded it and rode it yesterday now its back to just sounding like a broken sewing machine :)
