Cam chain slapping, slow oil pressure build up

[bigtremb]

Hi all, i'm having an issue since last year which is: when my bike has been park for a couple of hours/days, and I start it I have loud cam chain slapping( louder than it used to sounds) and as rpm reaches idle, the slapping goes slowly away. I have a feeling that I may have an oil pressure problem but I don't have any low pressure light. When the bike is warm everything runs smooth as a whistle.. last winter I did check my valve clearance...someone's in for brainstorming?

That noise should go away within a few seconds.  I rather doubt it's a low oil pressure thing.  You would have to confirm that with a gauge, though.  Could be the tensioner itself and in which case you could replace it with a stock one or get away from it entirely with an APE manual tensioner.

Have you used a different oil / viscosity since last year?

To kind of eco VJ

Here are some threads that may help you:

You're up early, C.

Probably. That's where I should be at 6 in the morning.  Now it's off to the local Dunkin for coffee and two (2) egg and cheese wraps.

Seems all C14's have this problem to some extent. Some worse than others. I doubt you have an oil pressure problem. Mine had it worse than most and not only would it rattle at startup but would slightly rattle at idle once the bike got hot. The problem with the design of the hydraulic CCT is that the ratchet system has too much clearance. It can move 1/8 inch or more. So once everything gets worn in, some bikes will get to another notch and be ok, others will back off as much as 1/8 inch sound like loose nuts and bolts are in the crank case at start up. My solution was to install an Ape manual CCT. Yes more work than the OEM hydraulic but really not that much maintenance. When I changed the oil I would back off the locking nut and with the engine running at idle, turn the adjuster in by hand until I couldn't turn it with just my fingers and then back it off 1/4 turn or so. A couple extra minutes every oil change. Once I did that my bike never rattled again and I rode that bike 73,000 miles before I sold it.

Ever since I was in the Army I can't sleep late. The alarm actually goes off at 4am since my wife is still working and starts at 8. Yes, we need 4 hours to 'get ready'. That includes coffee time and exercise time and occasionally another 'kind' of time.   

Mrs Conrad will be retiring at the end of June.

Normal. Mine did it and it has no oil pressure issues. Many many other brand new  bikes do it. I had mine replaced with a brand new one under warranty and it still did it. Some say to start the bike on the center stand.. no thanks.
Best advise. Install a manual APE tension-er and  NEVER hear it again.

Braggart! ..or... just to stay on topic, are you pullin' our chain?

No chain pulling involved Marty.
