CB750F2 head gasket

(1/3) > >>

Spitfire:
Well after working on the grandsons bike and getting in some riding time on the F1 I decided to do something about the various lumps of metal dotted around the garage, these make up a 1977 CB750F2 that I bought in the late 1980's to give me something to play with. The bike had sat out in the rain with the plugs out for a couple of years so I rebuilt the top end with new pistons, rings valves etc, stripped the whole bike and resprayed it all red, then in 1994 came the chance to work overseas so off I went for the next 10 years. When we came back (2004) it was time to overhaul the house, this took a couple of years, then another couple of years to rebuild my CB750F1, but I never got around to finishing the F2, I started painting all the parts black and took down the top end of the engine to check it out.
So now I have started to rummage through the parts that I bought for the rebuild way back when, I have found a new gasket set from David Silvers (KP) which I bought for the F2, and the remnants of an NP set which includes a head gasket as I always use genuine Honda head gaskets, I also found another head gasket sandwiched between two pieces of grease proof paper with no markings at all, this one has the small stud holes in all locations so I think it is an earlier one.
The question is as the genuine F2 gaskets seem to be extinct which one should I use the KP one or the NP one as I have no experience of either, trawling through other posts on the subject seem to say keep away from the Athena one.

Use the origanal and make sure all the oilways are supper clean on the i am only doing this once principle

Spitfire:
I'd love to use an original gasket Bryan but they are extinct.

I only have experience of using NP gaskets on CB250 / 350 K  & CB400/4's but must say I never had any problems with them.

Wonder what DSS uses. I will ask him.

What's that lockup of yours looking like these days BTW Bryan. I remember you sent me  a photo of it years ago and it was stacked to the gunnels!  ;D

Cheers ... Ash

Spitfire:
Thanks Ash, I have just checked out CMSNL and they have originals but for 124 euros, so I think I will go for the NP one !

Cheers
