Well, I fixed the muffler. It was hanging off there funny and the copper fitting wasn't sealing up very nicely and was making my engine all full of oil. so i bought some muffler cement and sealed it up nicely. I also bought a really bright LED flash light and zip tied it onto my old light mount. It lights up the whole road! Its pretty sweet. It is quite bulky on there though. I frequently like to sit on the rack so that i can crouch real low so i mounted my tail light on the old reflector bracket. It has gone through just over a gallon of fuel. Today i bored out the manifold as far as i could, it made a HUGE difference! now i can easily get up to 55km/h without peddling. when i peddle, I can get up to 60 no problem. I haven't tried going any faster than that. Thats fast enough. At my cruising speed of 50, i have nice mid range rpms.
