Custom fit: The example of the BMW in the picture gallery shows where selecting items from the TM40 pumper page and some owner initiative has made this work a treat. Everybody also knows about the benefits of fitness products from our blogs, especially- the Smart Hula Hoop, Neck Pillow, Stepper Workout Machine, and many other home gym equipment. Day two of our three days of track testing provided some interesting observations at Transport Canada's banked oval during top speed runs.

And put some Loctite on the 2 AP adjuster screws, because folks say they can vibrate themselves loose/tight over time which would affect the AP jetting. After freshening up the top-end of my XR650L this winter, I decided to top it off with a “better” carb.Normally on non-pumper, non-CV, mechanical slide carbs, like Mikuni VM’s or Keihin CR’s I’ll go a hair rich on the pilot circuit to yield better instant throttle response. The engine’s forward lean has been reduced by 10 degrees, making it more compact and allowing a 20mm shorter wheelbase. The stance of the Yamaha is low, with a smaller frontal area than the Suzuki and a seating position that feels tucked inside rather than perched on top.

The thing I like about it more than anything else is I can start my bike every time without messing with a choke.In full-bore acceleration, both bikes produce enormous power but over such a broad range that controllability is much better than on less powerful but peaky machines.
