Hey guys new to the forums here. Just trying to get a little help. I picked up a ltz out of a junk yard. 80 bucks. Everything was there except seat, some plastics and front wheels. Replace the starter, starter solenoid, carb, coil, plug, put raptor 660 petcock, jetted to 155 main and 25 pilot, new air filter, changed oil, sprockets and chain and took the airbox lid off. It's got a yoshi slip on I'm pretty sure(doesnt look like a full). Fixing to pick up a 434 big bore kit. But wanna figure the issues out first. Issue is it bogs hard on a second gear clutch dump and cuts out at 3/4 to full throttle pretty bad. Seeing if you guys with better ideas on these quads know what I need to look into. Next option is shimming the needle 2 to 3mm .
