So exactly how much is "alot more" power? And how do you know that? Can you answer me, or you just think so, for all the work you did?
I can't recall anyone on here in the past 3 1/2 years since I've been on here who could answer that honestly with any objective data, except to say "my bike seems better, it runs better, it's quicker", or whatever. And then they come back on multiple other threads asking questions about further carb and exhaust and air filter mods to try and get it to run right. All I can say is that with proper maintenance my stock bike ran perfectly, never had a problem, always started when it was supposed to, got great gas mileage, and all that made me happy. You know better than the Suzuki designers so give them your suggestions, go work for them designing a reliable simple bike like this.
And I would never buy anyone else's heavily modded bike, it'd be too big an effort to get it to run right again and maybe have a shortened engine life to boot.
Like I said, have at it, tinker all you want, it'll make very little difference in the end result but it'll make you happy which is all that counts.
The end.
