Yeah I am never taking my bike to them again. I for the most part can perform any mechanical work on my bike but I lack a little knowledge when it comes to jetting. I have not had the time to actually get on a dyno and make changes accordingly. You know your one of several people that I have heard the T6's dont compare to the older model T5. As far as I know, Duncan does not have a dyno but dont quote me on it. As a matter of fact I dont think they do. How about thier pyramids? Are they decent vavles? My porting is high on the exhaust side so I am loosing bottom end but it tends to make up for it on the top. I am seriously considering redoing my bike completly. Should guys with pipes, k$n keep up with me? I know I wont beat them by 15 bikes but I was expecting my bike to run alot faster than that?

I ran the bike hard threw a few gears and when I check the plugs they seem to be a blackish color. I am riding at gordon Wells with temp ranging anywhere from 80-90. the current needle position is in the 3rd position(from the bottom) and they are cg-j needles. The jetting on the carbs is 165 main and 58. Is that about right? I dont think my bike is running at its best.

Hi, My name is Nick and I am new to this site but not new to riding. I recently had my bike built by Duncan racing and I have a few concerns regarding thier tuning. Well to begin I have just about every single mod to a 350 without stroking the motor. I have thier pyramid reed vavles, port and polish, welded crank, power head with 18cc domes, 34mm Kehins, intake manifold with boost bottle and T6 Pipes and k$n. Also, its 20 over so the displacement is a little bigger. From the get go, Lauren from Duncan didn't like the fact that I had T6 pipes and thats totally understandable. My bike is fast but I dont think its anything it should be. My friend who weighs 260 pounds on a bike with mild head, T6 pipes and k&n is giving me a run for my money. I only weigh 170 with all those mods and I cant seem to walk him. I knew our other friend who had a shee with pipes and he weighed about 115 pounds and he would stick with me the whole time up the hill. the funny thing is I asked Duncan and they said they were willing to let me try out their pipes to see how I like them. I think that they purposly set my bike up like that so that I would get their pipes. I am not accusing anyone but I bet if I let them tune my bike with thier pipes it would run like a bat out of hell. I am not that great with jetting but it seems a little rich. What size jets would you guys run?
