I recently put in a new hotcam, and the thing makes a valve "ticking" sound (the lash is set right) when the bike warms up. I was thinking I might try some 20W50 to reduce the noise. Anybody think this is a good idea??

I was told to try some full synthetic to help quiet the ticking sound the hot cams make. I would stick to a 10w-40 full synthetic.

What makes the hot cams tick?

I was told it is the stock springs working harder due to the cam having more lift and duration. It kinda sounds like the valves are out of adjustment.

So would stiffer springs get rid of it? I've been thinking about hot cam stage 2.

Im not sure? I have heard the Webb cams are quieter but they use stiffer springs. I guess it's possible. The hot cams are designed to work with stock springs,piston and rockers though? It's not that bad though. My Barker pipe is Friggin loud as hell! So I don't really notice It that much.

I've had 4 different cams in my XX and they all made noise.

not a good idea do not run heavy oil in these imo run good light weight oil


readjust valves they need to pull tension with the measurement not just be able to fit in there one person defination of .008 and another can be .003-.004 apart you probably have them to loose

Im afraid i got um too tight now it coughs a little sometimes on a hot start. Also i would be fine with running $9 a quart oil if it helped

I changed the oil today (lucas semi synthetic high performance motorcycle oil 10W40) and readjusted the Lash....... The cam Is quieter now but the hot start issue is still there..... You don't think I have the lash THAT tight do ya??? I would call it medium drag on the gage.

Its harder for the engine to push that heavy oil to the top of the cylinder especially, if its cold outside.
