stock head gasket thickness?
 

Really odd question but the valve guide issue is fixed and getting ready to put everything back together.

I have been back & forth over my HD manual & can not find the PN# or the thickness for the damn stock head gasket thickness.
(88TC, 2000 Ultra Classic)

I have seen several different thicknesses listed for this gasket, is there a advantage to gain in changing the thickness of the gaskets??


As always thanks

I have no idea what the stock gasket thickness is for the TC 88's, but it's .045 for my '07.

.045 is the number my man.

040 give or take 05 will work ..

Thanks guys I've been burning the candle at both ends with work & working on the bike. Think I'm going to take a day off till the parts get in.

IIRC, FuelMoto worked your heads and they should have told you what thickness head gasket to use to hit the target compression; that's the thickness you should be using.

No head work, just putting it back together. Was running with a poor A/F mix so the valve in the rear cylinder was hanging in the valve guide.
Now I'm getting ready to put it all together. Looking at new orders :icon_banana: so I don't want my bike sitting in parts when it's time to transfer.

Then why not use a .030" and boost the compression .25 points?

Sounds good to me. Thanks

Best to do a deck check first. You're shooting for about .035 squish, give or take a couple. About 6 months ago, I assembled a 95, the pistons were .002 and .003 proud, I used a .040 head gasket for that one. On my recent 107 build, both pistons were .008 down, I used a .027 head gasket. If you were flush deck, you'd want a .036. Cometic makes mls gaskets in several thicknesses, get the one that works best for your applications. The difference between .002 up or down, and flush deck looks pretty much the same to the naked eye. (at least to my old eyes). A .030 head gasket will work in many applications, but I always try to check deck height before ordering head gaskets.
