New to Boulevards
 

Hi everyone. Just did a deal for a 2006 C90T with 13,000 miles. I've been riding for 35 years and have owned about 15 bikes, all metric. The C90 I got has sat for quite a while and was ridden very little by the previous owner. Under full throttle acceleration there is a weird vibration, almost like a stutter. I dosed the gas with Duralt, a fuel additive that is WAY better than seafoam, rode it for ten miles to let the additive get to the injectors and today I'm going to change the plugs and check the air filter. Any tips will be greatly appreciated and I'll update any success I have with it.
