Well I dropped my tb parts cam of to get a cam installed and they reckon it's making a noise after they installed it.

I told them to set the valves sales as stock. 004/.007

Any ideas of what may be causing this?

TB cam is based very closely to a DCR cam which is a regrind, Due to this the base diameter is small making the valve lashes that are stock essentially bigger percentage wise, thus creating more noise, also ramp rates and lift are greater so there will be even more noise.

Needless to say its normal, run it, keep valve lash settings stock at .004 and .007, take it for a full heat cycle of about 10-20 miles and check valves again when fully cold. Then check again in about 100 miles to make sure things havent moved and then call it good till the next scheduled valve check.

If it's a ticking noise then thats normal. Also, I hope whoever installed it added locktite to the cam bolt. I don't want to scare you but some users on here have had the bolt come loose and boom.

When I was running BrianS 170 BBK kit engine using the Crower reground cam I set my valve lash at .002 on intake and .003 on exhaust or if I was worried about heat expanding the metal parts I would set the intake at .003 and exhaust at .004

I know my Takegawa 181-4v valve lash are set on both the intake/exhaust at .002 and max at .003. I would set mind at .002 with .003 unable to slide under the lash.

Dealers have some of the worst mechanics. I wouldn't have much confidence in them.

The powersports industry is tanking right now so they must be doing something wrong to lose Honda during this rough time.
