Night Train noise
I bought an '03 Night Train about 2 1/2 years ago with 12k miles on it, now its got 27k. It appears that the motor, transmission, and drive train are stock. The place I bought it from didn't know of any modifications to it.
I have never abused it, and have just changed the oil and filter for the third time, and put new plugs in it.
A whining noise started coming from it that became a tapping/ knocking sound within a few days. I can't tell where it's coming from.
I was told that the cam chain tensioners wear out at around 30k miles, so I am about to pull the cover off to see if that's the problem.
Anyone had experience with this? Should I change the chain driven cams to gear drive?
Thanks

It could be one of several issues. Check those tensioners for sure but it could also be a cam bearing, loose compensator nut, primary chain adjuster, the list is long of the possibilities.
Dont rush out and buy gear driven cams until you get the crank runout checked.
.003 max for gears.
.003-.006 convert to hydra chain or keep stock chains.
.006 ish and over? send the crank out to get fixed!!!

They are the best thing on the market right now for the twin cammed bikes.
If you do the research you will find that gear driven cams are falling by the wayside in favor of the new Hydro tensioners.

With the HD kit, it is half assed you are still using the old style inner chain.
BTW, start with the easiest place, check the primary chain tension, then the comp nut.

about the primary drive -
I got the bike with 12k miles on it, rode it about 1K and the comp sprocket came loose. I loctited and torqued it to 165 (not sure of the accuracy of my torque wrench). rode about 2k, came loose again. upon closer inspection the picture in the manual showed a washer under the head of the nut that wasn't installed in mine.
i checked the length of the nut and it was bottoming out on the end instead of under the head! i took about 1/16 off the end, loctited and torqued it on again. no problem for 12k miles. then i heard noise, first thing i checked was the primary. the comp had come loose. loctited and torqued it again, but when i started it up there still was noise. so now i'm on the other side. took the cam cover off and out falls what's left of the tensioner shoe. any reason they would both happen at the same time? or just lucky. that andrews kit sounds like the way to go, so i've got to find out what that will cost. the gear drive would be about 800 for parts and my friend lent me the tools. would i need other tools for the andrews kit?
thanks for the help
