New to the forum, also new to doing a full rebuild. Always have done just topends. Bought a Clymer's book and started in on it. Got a 2000 Blaster that I chose to put a non ported Vito's +3mm crank and BBK in along with new bearings and seals. For the sole reason of drag racing my neighbors relatively stock and worn out 400ex, he's always dogging on my Blasters lol. $1000 on the win and $500 on a gap, yes I had several adult beverages at the time. Did a oil injection delete kit, deleted the TORS. Pro Circuit Pipe idk the ### and DG Type II silencer #155631. Vito's carbon flex dual stage reeds in the stock cage, spacer, Upp 34mm intake boot, Brand new genuine Mikuni 34mm round slide VM series carb #VM34168, 35 pilot - air screw is 2 out, middle clip on a 6DH4 needle, needle jet is a Q-2 159 series, main jet is 360. I have pilot jets 15-37.5 and main jets 290-380. 4" 15° Uni Pod filter. New 1/4 fuel line and new petcock. Mixing Klotz KL-200 at 32:1. Stock gearing, 21" generic Holeshots. Have 22" tires and 14 - 38 gears, 400ex rear shock to play with and find the best combination for a straight line. Bought a used KOR 240 high comp head that I planned on putting on after break-in and getting the jets tuned in. Everything was relatively simple with rebuilding this engine piece of cake really. Starts up, runs, no weird noises or fluctuations. Runs rich on bottom end which I'm good with. 1/4 to 3/4 throttle is spot on atm. Top end gets lean very lean with the 360 jet and the plug shows that but is to rich to rev out with the 380 jet. Makes me think my needle is the wrong size effecting the main? I haven't done a leak down test yet, just built a test rig today and gotta buy a bicycle pump as well. Won't be messing with it till I get it tested of which should have been already done. Yes it has the newer 03 and up front plastic on it. Thoughts on this contraption?
