Hi i know this has probably been mentioned in here before, but i think my carb needs attention. i have never delved into carbs before and i have no idea how to set it right. what i would like to know is (in simple terms ) what jetting i should be using etc. Oh! and it's a Dellorto, Thanks

hi there! i'm trying to jet my berg. it has a full silmotor with no dbkiller. i opened the keihin and it was running with 45 idle and 175 main. switched to 50 -> 190 and runs much better but when i kickstart it i need to pull the throttle a bit before or it won't start!

So 14/50 on the 06 Fe550e is so good for real enduro woods trails, very nice, it shortens the distance from 1-3 and I see 4th gear now! ..... but the bike is not as jedi berg fast as before, now it kinda fights the gears rather then speed up into each one. I can see how a racer would want...

Hello all - I live in a remote area of Australia where due to fuel sniffing concerns in the communities they have banned fuel which contain aromatics. The colourless alternative named Opal, is apparently 90 octane at most and unsuitable for anything high performance. I have a sneaky deal going...

I'm prepping my 450 for dry dirt(if it ever warms up here). I removed my e-starter and battery, as it has always kicked very easy, and still does even in winter. It looks really cool w/out al the electrical equipement, in addition to the weight loss. I have been trying to get a hold of Mr...
