Five Days of riding at Troy Meadows
Posted July 04, 2000 - 02:29 PM
Riding elevations ranged from 10000 to 4500 feet over the week and I had jetting problems. I started the week with a 45 PJ and when my bike got hot it would not idle and was extreaminly difficult to start. Of course I had the 45PJ in while riding at lower altitude on the toughest trail, the Rincon, and it was no fun havng your bike die almost every time you pulled in the clutch to stop. There were three of us on this ride and we all got tired of starting my WR!!!
I put in a 48PJ the next day and the bike ran better, ran cooler and started reasonably well. Last year I had WR timing and ran a 45PJ with no problem. This year with the YZ timing and the FMF PCIV-2 and Power Bomb I needed to richen up the pilot circuit to get the bike to run properly.
I ran 13/47 gearing, which is about 1.5% lower than stock and with the FMF exhaust it pulled everthing just fine. I thought it might have been too tall but it worked out great for trails and dual sporting.
I really missed the jetting for the altitude conditions and should have know something was up since on the dual dogs dual sport ride a month ago when my bike got hot it became vary difficult to start at altitude, was running a 45PJ at the time. Guess I'm going to a 50PJ for home 1200feet and a 48PJ for the higher elevations. Will let the fourm know how things work out.
Now back to work and no play for awhile

I actually ran the same setup I had in from Denver, 6000 feet. 175 main, 48 pilot, YZ needle 4th clip and 1 3/4 out.
The only problem I did encounter was it wouldn't start on the very first kicks before riding. I had to use the hot start button with no choke on the cold bike. But after that, no starting problems.
I was kind of baffled as to how I got away with it. Bryan also ran the same Denver setup when he rode the same area I did the day before. He also had no problems. He thought the YZ timing may be less finicky to jetting changes.

The weather was perfect lows at night down to 38 to 40 highs during the day between 75 to 83 degrees F. There was occasional breeze which was refreshing. I wish I was up there now instead of in Valencia where it can get real hot.
