I picked up a 82 xs650 a couple weeks ago. Someone had already attempted a bobber project and failed. Most of the parts were in boxes. over the past couple weeks I have been going through it working out the bugs. I got it to run but shitty. I pulled the carbs apart and cleaned and inspected them. everything looks intack and they didnt seem to be too dirty. However I did not soak them. Put them back on with a nice clean tank and fired it up. Fired right up with the choke and idled fine after about 30 seconds. let it warm up and went to take it for a spin. if I peg the throttle it will shut off. if i ease into it it acts like its only running on two cylinders and slowly starts to get better. then while still holding the throttle it will go fine. If i keep it in the upper rpm i can go through all the gears and it runs great. if i let the rpm drop it will start studdering again. I dont know if it makes a difference but i am currently running with the back half(including crossover) of the exhaust off. I have tried it with the four cone filters and with no filters. Any help or ideas would be great. Thanks
