Mystery Motor

[toyotaman]

I bought a motor off of Ebay, it had never been fired and the guy I got it from didn't know much about it. He got it from a friend who supposedly built it at a shop he worked at near Portland Oregon. The reed spacers have Moore performance stamped on them. I've taken it to some of the local shops, and here is what I know so far. It is bored 50 over, ported extensively for top-end, lightened flywheel, Wiseco pro-lite pistons, Pro-design Coolhead w/16cc domes, V-force reeds w/aluminum spacers, boost bottle, stock carbs w/tops TORS eliminated, 330 main jets, needles are on 4th groove, stock pilot jets, dual KN pods, Toomey T-5's, Dyna ignition, adj.timing plate. I got just the motor off Ebay and already had the carbs from my other motor that blew up. I put the 330 mains in it. I had it leak tested(It's tight), had idle screws tapped into the carbs. It was adjusted to run and idle by a local shop. It runs and idles good, but has no top end and bogs at at anything past 1/2 throttle. I was running a 40:1 mix with Yamalube oil. I mixed 2 gal. of premium and 3 gal. of 110 oct. race fuel. I did this at 1800' elev. but want to set it up for the coast or sea level (dunes). Plugs were black at that time. The Dyna ignit. is set to stock, but there is also an adjustable timing plate on it. If i'm reading it correctly, it's advanced 8 degrees. that seems like too much. I'm not sure if I'm doing it right, but I'm reading it by the tick mark that is in line with the split in the case. I know that there is many variables, but I'm not a pro racer or even a mechanic, I just want to get this thing to where I can ride it without it blowing up and then fine tune it. Should I be running higher octane, like 114, and possibly be doing without the premium mix?Is my timing too advanced. I really need some suggestions on basically everything!!!!! I'm overwhelmed,Please Help!
