Eli, that may help, as would fresh gear lube in the transaxle. OK, here's where I'm not completely certain but will still offer some thoughts...If the problem persists, I'd look at dropping the drivetrain so you can inspect and refurbish the shift fork. It has bushings, bearings and the shaft itself that might be worn. The later Carreras with a G50 tranny had some problems with the shift fork that were solved with an update to the fork assy. Ask RL. It may have been an issue with 964s, too, but I'm not certain about this.
