Hi all. Hope i am in the right topic area... As much as i would love to lash out and buy a bigger and more powerful bike, my budget (and pregnant wife) dictate that i need to 'think outside the square'. So, i am wondering what, if any, simple and affordable modifications could be made to my bike to get a bit more grunt out of it. It feels like when i need to get it moving, i have to just about strangle it. I am not that familiar with the detailed technical stuff but will happily hand over to my local bike shop with all suggestions in mind. Was told by a friend that changing the rear sprocket can help with off the line speed and putting a sports exhaust on could add a few kw's. I have searched through the thousands of posts but couldn't find anything. thanks for reading. cheers. Zab.
