Steel pinions to match the steel spurs for the magnum nx/funfactor.I attached the thread about it to an email and send it to cen.They emailed me back and said they were working on a fix.Can you tell me how this fix is coming along?Sure would be nice to have mine back on the road,but as long as I have to change out the gears with every half gallon of fuel,my magnum will continue to collect dust[:@]See what you can find out about the so called fix and post it here.Thanks,sure would help[:'(]
