Quickest throttle

We are using the Boysen Quickstart in two of our race bikes and the difference in throttle response is impressive. One of these engines is stock, and one is a highly modified 490cc. Both set-ups have responded well to this mod and hot engine starting at the entry gate is much improved. Highly recommend this to all.

Crap

Plugged it in and nothing so I sent it back and got another and the same thing. Not a light came on- the instructions say 4 seconds and it should turn on after it starts but it won't event start. Just garbage.

Carb Kit

Great price and everything you need for the stock carb rebuild. Nice clean new parts that are strong and seal well. I used this kit on a Yamaha Big Bear 350 4x4, and it really helped bring it back to life.
