Nick,
I'm down here in Vegas. I have an 03 that I've been able to kick start a couple of times cold. I ended up changing to an 04 cam and starter which helped a ton with the button. Lowered my cranking compression from 105lb's to about 82lb's give or take a few.
I've found short, like 3 second burst on the button makes a big difference in the success of starting 4-T Gas Gas bikes. Unsuccessful the first two or three times, turn the key off for 10 seconds or so. Hit the button again, it'll start. I also think the trim needs to be set correctly. For Vegas, 2300 ft in elevation, It starts easier in the 35 to 40 range. I have a 4T 04 quad that stalls at slow speeds or idle all the time unless the trim is set in the 35-40 range.
So, now I have an 03 cam sitting around. Have you personaly modded a cam for lower cranking compression? I though you had to add more metal to the decompression dimple?
A set of nice digtial side by side photos would be cool.
Hope I didn't hijack the thread with my old FSE story.
Mike.
