Bonneville America Forums Forums Technical Forums Performance Mods Big Bore- Is it really worth it??

I got the 904 big bore, while we had it down, ported, polished, & shaved a bit off the head. Worth it ??, heck yea, it's like a different bike. I run the 18 tooth front sprocket, & now on the low end it pulls hard. It's still not a sport bike, or R-3, but it's alot faster than it was.
