Hi all, I have read every post I can find on this forum about jetting and uncorking the BRP. I have had my BRP for about a 2 weeks. I rode for one week all pluged up and was not impressed. All my previouse experience is desert racing big 2 strokes in the ami class, I wanted a bike I could dual sport and chose the BRP. I unplugged the bike and started at a 172 main and felt a huge improvement, now I felt I could live with the pig except that I went up the mountain to about 4500 and the bike had to have a rolling start to get going again. After this I went to a 170 main and felt yet another improvement in power but now I am afraid of getting her a little too lean. The big suggestion is going to the 175 main at sea level. I live at 3500 and ride between 2500 and 7000. Does anyone think the jetting guide in the honda service manual is still accurate for the uncorked BRP? If it is correct I should apply a .92 correction factor to the 175 which gives me a 161 to 162 main. Does this sound correct? Any suggestions will be appreciated. Thanks Mark.
