Thought id update some changes to the 500. I decided to try the Pulse Intake from Ron Mccord and shelve the Smarty for a while. After reading about it and talking with Ron Mccord, Adam Millar and a few other Pulse converts i ordered one up and installed. It actually fits very nice on the steel frame and took some fitting and adjusting especially with my heater. The carb i decided on was the short PWK from a YZ250. Its a little shorter than the standard 38mm PWK and gains me a 1/2". I wanted to retain the stock airbox and filter location. With the heater installed it fits perfect ! Last season i ran a custom Pod filter setup which worked well but i wanted to get back to simple.
I tried to make the Avid fit the steel frame and due to it being square it would only fit on a diagonal (both Smarty and PWK, steel frame) Also with the YZ carb i found the Avid heater would not slide on all the way at the bottom where the bowl sticks out. It fits much better on the standard PWK.
I decided to machine my own carb heater on M5's lathe. It turned out sweet and fits the steel frame most excellent. I then tapped the back of the CR500 cyl for a nice short run to the heater with a valve. We also tapped the bottom left rad for a nice 90 degree fitting. I will most likely put another valve in the return line. These heaters get hot. I cant see carb ice forming with his setup. I bet running the valve half open will work well.
I will post my findings with the Pulse after i get a good solid few rides. My initial thoughts are it starts first kick, idles smooth, and there is less vibration. Pretty stoked to try it out with some real carb heat !
I plan on running my big Eline stator once again. It works well and is very robust. I plan on running grip heaters, Cyclops Solstice HID, GPS powered by CR. I learned a lot about what works and what doesn't when it comes to the stator and wiring accs.
