okay when I re did the topend on my 2002 kx 250 I couldn't get the indented teeth on the gears to line up with the marks on the shaft. I took it to the shop and the guy said I they where fine but I'm not sure if I can trust his opinion. What do you guys think? everything seems to be working correctly it's set so it will open all the way at full throttle and so that it is closed at low throttle. I did notice however that I am getting a bit of bogging at mid throttle right after letting it warm up for 5-10 mins but that cleared up after riding a bit. I havn't had a chance to open her up yet cause I am still breaking her in. I'm thinking the bogging is being caused cause I moved the needle valve to stock position cause it had been lowered a bit before I had it.
