Because as many of us have already tried to get through to you...
The cost and aggravation will NEVER yield the results to justify it.
It is a single cylinder, air cooled, mass produced for the best affordability/reliability platform. Not in any way, shape, or fashion an adrenalin junky's fix.
It was never intended to be a horsepower maker.
Come on man...
These things put out under 30 horses stock.
What you are proposing is basically pouring thousands of dollars and hundreds of hours in design into a platform that can be picked up for a few hundred bucks.
That's like spending 20k$ on a 1k$ honda civic, building up so you can keep up with stock muckstains...
It's clown shoes.
for most of us... money actually means something.
Keeping the bills paid...
Things like eating once in a while are nice...
I just went through the motions to swap mine over to the 95mm high compression setup...
My bike had just under 4k miles on it when I brought it home...
It is a 2006.
I gave literally 450$ worth of labor for it.
I was able to justify the 650-700$ or so that my build totaled.
But it was only because the oem configuration failed on me and parts replacement was necessary. For what the bike cost me, and the parts... It was worth it for me to salvage the bike. It would never make sense to me to go any farther with performance modifications.
Seriously man...
If you have been on one of these above 80mph... You would not want to go much faster. The front end gets kinda squirrely.
Like others have said... It's your bike... Your build... Your dollar.
But to be honest... The questions you are asking lead me to believe less of your technical capabilities. Someone ready to stroke out one of these motors, and hit it with laughing gas... Should not be asking about compression ratios, bobber kits, or any other remedial mechanical discipline. You are entering big boy territory.
I'm not making an attempt to talk down from a pedestal man...
Just trying to reel you back in closer to reality.
These bikes have been around and pretty much unchanged since 1986.
If it could have been reasonably done... It would have been by now - 32 years later.
No you just lack the ability and the resources to do it next time keep your two cents to yourself.
I'm just trying to see what people have done to the scene to Max it out so far so I don't have to do as much research but obviously I'll put down in my notes you don't know what you're doing so I'll start from scratch have a nice day
