Ok guys and gals it's finally time to ask for some help with a mid to high rpm miss fire I'm having on my 2000 quadmaster which causes it to backfire bad and wont allow it to rev past 3000 as per what my timing light is telling me. For the past 2 weeks I've been trouble shooting this issue and for the life of me I cant figure out whats wrong. Here's a little background to what I've done so far. 1. Cleaned and rebuilt carb all jets and settings are in spec. 2. Checked compression and valve lash a 3. Battery voltage stays steady at around 13.8v 4. Ohms and peak voltage tested everything as per the oem service manual and no problems found 5. Removed stator cover and found no physical damage to stator or pick up coil or magnets 6. Bought a new ignition coil and spark plug plus used cdi 7. Checked all wiring for damage and cleaned grounds 8. Disconnected rectifier and stator to eliminate that as possible cause 9. jumped power and ground direct to cdi I know Is an ignition miss because I purchased a inline spark tester so I could physically watch the ignition system in action. It starts and idles smooth with a consistent flash from the spark tester but as soon as i try to rev it up I can see the spark tester skip and my quad just backfires and wont rev past around 3000. Ok any ideas?

Dont kno if i would exactly call it a missfire but sometimes when i fist get on my quad( after letting it warm up with choke for five mins ) and rip away usually right after shifting it will miss 1 spark blow that air/fuel into exhaust and backfire then run normal sometimes itll do this 2-3 times aways in the beginning of a ride usually if i warm it up a little less then usual, just curious what would cause this. It did it since i got the quad 6 months ago and theres a different head cyl. And piston in it now...also what would cause oil to stop flowing into a head??? Or did i screw something up??? On the new head i noticed oil poors out behind cam sprocket on the old one it didnt

I miss it already and it hasnt been a year.. I have a 1994 Camaro z28, LT1 v8 Color is red I'll email pictures upon request @ [email protected] Modsthe good) Subframe connectors cold air intake 58mm BBK edelbrock throttle body edelbrock headers flow master exhaust (sounds mean with the headers) lowered 2 inches in front ported and polished intake motor rebuilt 40k ago trans rebuilt 1k ago with shift kit and hardened shafts.(for nitrous) motor is internally sound and hardened internals for 250 shot of nitrous!(wooo juice) Has new 3.73 gears on 10 bolt solid rear end.(posi) has new nitto drag radials with under 10 passes on the 1/4th Has kelley steel belts up front Weld Drag lite wheels rear are 8X15! AND FRONT ARE 5X15 SKINNY FRONTS! Overall car looks pretty good for being an older car. paint has a few scratches and dings and i have a NEW front bumper for it, but it will need painted. oh and has a 1800-2000RPM torque converter. the bad.. Interior needs help, but not much, headliner is sagging,(pinned up) Dash has a crack and driver seat has a rip, this is all pretty common stuff so no suprises there. needs the turn signal switch its like 20 bucks? maybe less idk brights wont kick on and left turn will get stuck on. thats about it. I maybe have misses some stuff but overall car is awesome and very fast. again email me with any questions or trade offers, looking for another car? maybe quad. have cash if yours isnt worth as much as im asking (4500) fair price i assume maybe a quad+ flat screen tv. or something along the lines, thanks! miss you guys!
