I just bought a 2006 Suzuki boulevard s50. I haven’t owned a bike in about ten years. It’s got 17k miles. Seemed to run and shift fine when I got it. It’s straight piped not sure if that matters. Anyway today is day three I rode it about an hour just cruising around town. Randomly it acted like it has no gears on shifter I couldn’t even get it into nuetral. Now it’s rough shifting in low gears just noisy. Motor isn’t making any funny noises when in neutral etc. any ideas on what this could be or what I should check
