Help Quick! Misfiring? Ex. Pressure on R not L?

[fast87]

I need help ASAP, i am goint to the oregon dunes and dunefest very soon(leaving this sat.),a nd suddenly had this problem, it started on the first kick as usual(after the rebuild a couple days ago), it has a little over an hour on the new top end, using stock virgin jugs(off of a 2005) with wiseco pro lites, i did four, 5 minute heat cycles, slowly adding mopre throttle each time, did a couple 3/4 passes after the heat cycles, ran fine but a little rich on the top end(bought a bigger main and the add-on "power jet" knob was richened 1.5 turns from where it was), so i expected that...anyway i rode it yesterday for about 45min total(2 rides), it ran great, lots of power up till the top end, and i parked it..today i go to start it, started on the first kick, ran poorly but i assumed it did that because it was cold, let it idle for a few seconds, sat there and revved it up a bit, then slowly rode to the top of the hill so i could clear it out without pissing off the neighbors, and it didn't clear out like usual, i felt the exhaust with my hand and the right side was very hot(unusual for a motor that's been running for 2-3min) with lots of pressure, and the left side was almost cold with hardly any pressure...so i idled down the hill and parked it immediately, took out the plugs and cleaned em(nothing unusual, some oil but no metal fragments), tightened the caps to the wires a little, re-tried with no luck...i guess i should check compression next, but i have to remove the tank for my tester to fit...man i'm REALLY fucked if i broke a ring and wasted 700.00 and 5 months that it took to get this far, somebody please help!!! i'm about to if this is a serious problem, i can also remove ym cool head to check for detonation, my timing plate is a modded stocker, i don't know how many degrees it is set at, so i put it a tiny bit past where it was..

i had my reeds out 2 days ago while i was building it and they looked prefect, i don't know the brand but i think they're 4 petal, 1 big petal with 2 smaller ones on eah side, stock cages, they looked fine then but i can check if i must, i also run a keihin 35mm carb with a graydon 2:1 carb adapter, with a K&N filter...i pulled out the choke 1 time and it didn't make a difference, if anything it ran a little worse.. Thanks in advance for the help

i figured it out!! , it was those damn red lighted spark plug caps, i paid like 20 bucks for them at a harley shop about a year ago, and now it came back to bite my in the ass..anyway the bulbs in em were burnt out, one was all corroded and green, and on the other, the screw at the end that goes into my spark plug wire just fell out when i tried to unscrew it..lol..now i'm gonna go down to the bike shop and pick up some regular ones, the red flashing lights looked sweet on top of my motor and i'm gonna miss em, but now i bet there will be less resistance in the caps, so that equals more spark!! Thanks to everyone who didn't reply , i'll post a pic too so oyu know which caps NOT to buy

wow those pics are HUGE (if mods have a problem i will delete em), anyway as you can see the green one on the bottom had a little water there for a while, it was all cracked at one end, when i lifted on a piece of it it just flaked off..lol, both the plastic sleeves that cover the bulbs(they look like fuses) are melted to the bulb, and both are burnt out..so i guess they were no good anyway, hopefully this will help someone fix their misfiring problem, also does the banshee use 5mm, or 8mm spark plug wires?? and if they're the same size an automotive wire will be fine i assume..

lol thanks man...anyway i did finally get the problem fixed, and it SCREAMS now!!! , after all that it turned out to be a faulty spark plug, i guess sitting over night made it take a crap on me , so it was a combination of bad plug caps, 1 bad plug, and it was running so rich because my "adjustabe power jet" was set too rich, like 3-4 turns too rich, lol, anyway i got it figured out, and if any of you are thinking about buying one of those add-on adjustable jets, i HIGHLY recommend it , with 1/4 turn of the dial i can feel an immediate difference, so now i can run slightly rich when i'm screwin around, and when i wanna race or get all the HP out of bike, i simply turn in the dial 1/8 or 1/4 turn...just gotta be areful not to over-lean your machine
