Personally, for my goals I don't believe a camshaft is necessary. I just want to get an honest 20-22hp out of one of these engines. No doubt it would help, but when you start changing cam profiles, you start to effect the powerband of the engine more, and I want to keep it happy in it's current operating range.

How about this ?

I'm eager to watch this play out! And yeah, that exhaust port is nasty.. makes me want to tear mine down just to do it myself. The intake port doesn't look too bad to me, until you hit the valve guide area. This could make an interesting winter project if you get the results we're all drooling over! :lmao:
Take lots of pics as you go! We're all going to want every detail. |

While I was assembling my bike I went ahead and checked my stock ports, and they are more or less the same. I was wondering if maybe it was just this particular casting that was kind of crap, but it wasn't. This most likely will be a winter project for me, but I want to try and get started sooner rather than later. My biggest problem is, I have other obligations through the year that require my attention more, so if I do get any work done it will either be in spurts, or all at once. |

^I wouldn't trust that coating to do much of anything that I am talking about. If you want to try it go ahead. I have my limits on things I would cheap out on.
Speaking of coatings. As much as I would love to do so, I am not going to dive that far into this. This exercise is literally just a matter of porting the head to see the results. I intentionally bought a second head for this so I can not only enjoy the bike while doing this on the side, but also have the factory head to switch back to if I discover I don't like the nature of the bike after doing said work. The whole ceramic coating idea was part of a "if I were to go all out" discussion. I wanted to keep this as pure as possible and not introduce anything to skew the results of what just simple port work can do with a more "high performance" carb. |
I just looked at the head again. It has a hemispherical combustion camber, so your bike will have a hemi in it. :tup:

Looking at a 32 or 34mm flat slide style carb with an enrichment circuit similar to what you just mentioned. I am open to, and welcome all ideas.

As I said, just considering at this point. There are a lot of variables to consider,
