• fuel filter
• vacuum hoses and any caps (if you're removed the stock air filter) that could be cracked
• MAP sensor problem

I had a similar issue with my Roadster several years ago. It's a long post, but if you jump to page 10 you'll find how to test the TPS. In my case it turned out to be the TPS and fuel filter.

What now? (bad idle and poor running)

The bike was running great then yesterday it started stalling, has trouble idling, and runs like crapp. All coil wires are tight, vacuum hoses and caps good, primary TPS replaced 14,000 miles ago, fuel filter 14,000 miles ago. Runs better at higher RPMs, but not right. It's my main ride- I'd...
