Cam replacement question....

[CranMan]

I ordered a XR400 cam from marcums yesterday...WooHoo!!! I also ordered a Honda tech manual. My queston is, are there any gaskets that I will need to replace during the cam swap? If so I want to get them ordered....Also, after the swap, will I have to go up alot on the main jet size? I think I'm running a 155 main now, but I'm not positive about that....

There is a gasket under the rocker cover but it is metal and you should be able to reuse it. If you want to replace it, it is about $25 from Honda.
