(I previously posted this on the TTR forum, but they sent me here.)
I am new to Thumper Talk and actually fairly new to riding. I live in Colorado and bought a 2005 TTR125LE a couple of months ago. I have done most of my riding around 9,000 to 10,000 ft. in elevation. I was wondering if anyone had any recommendations for what to do in order to have my bike run the best at those altitudes. Specifically, it would be really great to know what size jets different people have put in.
Just to let you know about my current setup:
Right now I have the stock jets in the bike (I believe that is 15 - pilot and 105 - main) and the bike hasn't had any other mods. The bike is pretty hard to start and takes a long time to warm up. I usually have to leave the choke out for a couple minutes before it starts idling on it's own. I don't know if that is normal or not... Anyway, even after it is warmed up it seems to bog down a bit when I first hit the throttle.
I was actually thinking about going down a size in the pilot jet (to 12.5) then just seeing how it runs. Does this sound reasonable?
Looking forward to your recommendations,
