Need help quick! (please!)

Recommended Posts

I got around to putting in my hotcam today, which means reshimming also... Everythings good but I have a Q. the stock intake shims were .170 and .175. both clearances were .004

The exhausts were- left- .009 right-.012 I need to know what shims to use where. The manual gave me a forumla but I didn't keep track of what side the stock shims were on. the stock exhaust shims didnt have #s on them? so what are they?

decomp was at .018

please help me figure out what shims i need?

You only need one intake shim, a 1.65. take the 1.7 and put it where the 1.75 shim was and that one will be good.

You need to mic up the exhaust shims so you know what you have in there, then you can figure out what you need.

I just measured the exhausts... one is 2.25 one is 2.30... which are rights and which are lefts?

You tell me, you should be able to swap shims depending on what side they came out of.

Sorry I meant left vs. right. Honda said what the formula was, they said you needed to know the stock sizes. I'm trying to avoid putting the cam back in and then having to switch the shims... If it has to come to that I will but I wanted to see if anybody had an easier way.

Here are the equations I came up with...

Intakes:

A=(.004-.006)+1.70

A=(.004-.006)+1.75

Exhaust:

A=(.009-.011)+2.25

A=(.012-.011)+2.30

Are those correct? What size shims does this tell me I need... I've never done this before so I'm kind of foggy on what to do.

How do you know which side they came out? There is no stock size shim all the motors are different.

For your top one you can take the 1.70 and put it where the 1.75 was. that will get you in spec. Then you need a 1.65.

Wait, I already stated that in my previous post. :cry:

The 2.25 you need a 2.20

The 2.30 you need a 2.325

This is assuming you have them in the correct side.

I had to take my cam off and then put it back on about 3 times because I mixed the shims up. The numbers were wore off so I had to mesure them with my verniers. Make sure your cam chain is tight, if its not your mesurment will be off because the left side cam bearing has a small amount of play in it. Also that black coating on your cam loabs will wear off, its just there to help the cam brake in.

Write down the thickness of each shim and what position it is in (l-ex , r-in, etc.). If you ever have to re-shim it will definitely save you some work.

You're killin' me.

If you have .004 clearance and you need .006 look at what shim you have and go down 2 sizes because each shim is in .001 increments.

If you have .012 and need .011 go up 1 shim #
