Hello Triple Brethren...
Like the title says, I have some questions about installing S3 pistons on my S1. Why? For the righteous pursuit of speed, horsepower, and fun (and not being able to leave well enough alone
)! Now, after reading up on the "old board", I've learned that I would have to have the upper crankcase cylinder holes enlarged. That makes sense: larger diameter=larger hole. Although if i went with S2 cylinders, it would be a direct swap. No larger holes required. But why settle on a 350 when I can have a 400? Less "headaches" maybe?
Here's my first question...could I swap out my engine internals and fit them into an S3 crankcase? Do all the S series bikes share the same lower engine (crank, connecting rods, trans, etc.)? I'm also assuming the cylinder studs are the same (spacing, length)?
My second question is...Would the S3 cylinders have to be modified in any way? I seem to recall something about modifying the skirts?
Third question...Can my S1 heads be transformed (machined) into S3 heads? I want to get them machined to the proper squish angle, so I was thinking that instead of buying some used S3 heads and having them machined, I'd save a few bucks and have my S1 heads modified. No? Undo-able? Not worth the trouble or cost? What the hell is this guy thinking?
Well, that's all the questions I have. I'm just in the "what if" stage right now so I'd appreciate any info, either to steer me in the right direction or convince me not to do it! Thanks.
Dan
