Hi All,
I have read thread after thread until my eyes have bled... The Big Valve Head thread, for instance, was very good, but I think it would be helpful if we could to get everyone's opinion in one thread, if possible. I would like to respectfully ask that people don't respond to each other's post. I am trying to make this a thread that has opinion's from those with experience and knowledge without getting into arguments, debate, etc. So, as an example, if Comnoz states that he thinks opening up the intake valve is one of the first things he would do, I would appreciate it if someone didn't criticize or add their own opinion to his choice. Just state your own opinions. Short and sweet!
I am looking for each person's idea on what would be common sense, best bang for the buck, modifications. Not trying to wring every last horsepower out of the engine. Just want to have more of what the Commando engine already gives us...
The type of riding I do is a combination, like most of us. Lots of country roads, twisties, mountains roads, some city street riding, etc. I like to ride fast and hard sometimes, but other times, just like to cruise along at moderate speed. But, boy how I love to feel the Commando come out of a corner and feel that wonderful torque!
I am hoping to keep the power band pretty much where it is, but adding more low and mid range torque. However, it would also be nice to have a bit more top end, and not have to worry about hurting the engine. Reliability is extremely important! Again, this is not about building a top of the line, high strung, screamer. It's about using common sense to get the most bang for the buck. I think there are a lot of us who would never be able to get all the potential out of a highly tuned commando engine. I know that is subjective, but that's what I hope to find out. For budget, let's just say a couple of thousand dollars. $2k - $5k tops.
So, given the above parameters, what are your suggestions?
First off, what year/engine would you use as a base? Head work? If so, what? New head? Pistons? Rods? Cams? What carburetors? Do you think it's possible to get by with a single carb? Increase compression ration? If so, how? Milling or gaskets, or combinations? Anything you want to add would be greatly appreciated.
Again, this is just each person's opinions. Please try to refrain from critiquing each other's choices. That just derails the thread. Feel free to post more than once if you come up with additional ideas.
Finally thanks so much to those of you who contribute your knowledge and experience to make this such a great forum!

P.S. I am just a dumb farmer from Ohio, so if you could keep that in mind when you respond, it would be much appreciated! :roll:
