Agree with PD. These pumps are very simple. There’s the huge convenience factor he mentions, and it’s there, why not use it? Sure it can fail, just like everything thing else on a 40 year old bike. I think if you’re going to push the fuel ratios (bigger carb, bigger cylinder), it might make more sense to delete, because now, you’re out of factory spec. If it’s stockish, I’d use it. They’re cool to top it all off.
