Do the Andrews cams make more noise than most of the other aftermarket cams?

 

I had 54 g andrews and they never made any noise other than the normal

 

XL Cam noise is more a factor of establishing proper gear mesh, and valvespring tension. If you're running heavy springs, and if your cam gears don't mesh perfectly, you'll have a bit more valvetrain noise. Clicking may not be nice to hear, but, it doesn't hurt anything. If your cam gears are whining, the gear mesh is too tight - you need to pull it apart and get the properly sized gears pressed on.

The measurement procedure is outlined in your factory service manual, as well as the Andrews website.

 

I installed the cams using their directions and checked clearances as it showed so I very sure that that part is right. I have narrowed it down to the front exhaust valve. It looks like either a bent push rod, bad rocker or the rocker bushing. I can spin the motor over to t.d.c. and place a screwdriver on top of the valve and raise the rocker up enough to see light between the rocker and the valve.

 

what year is the bike? does it have hydraulic lifters?

 

01 and I put new ones in when I did the cam change. I'm going to check it out more after work tomorrow. It had a small clicking randomly before the cam change. I figure the higher lift finished off what ever it was.

 

How long have you run the engine since the cam change?

 

About 100 or so miles. The lifters has had plenty of time to pump up. I'm going to check the push rod, rocker bushings and pins tonight. I'll post up what I find.

 

No, most cams are made by Andrews anyway, just different specs. I've ran 3 different grinds of screaming chicken cams, they all steamed loud to me.

 

The gap between the rocker arm and valve was caused by the rocker arm shaft and the bushings. The shaft has 2 bad grooves where the bushings ride and the bushings were elongated. Looks kind of like they had been oil starved at some time. I know that oil is not the issue now for sure because I put a new oil pump on after the cam change. Just hope the socket where the push rod goes isn't damaged looks kinda border line. Hope to get back to the normal noise before long.
