Rocket Roadster Won't Idle - Please Help

[nadavis]

Hello Everyone,

I bought a lightly used 2014 Rocket III Roadster from a local Triumph dealer that came with custom straight pipes the previous owner had fitted. The problem is when I close the throttle when coming to a stop the bike dies about 80% of the time. Also, the bike won't idle about 50% of the time.

I'm no mechanic but I think it's a fueling issue. The air-to-fuel ratio is off, needs a tune, the throttle bodies are out of sync.....I really don't know.

The dealer won't help, even with the extended warranty i bought, because the pipes aren't OEM. Also, that particular dealer dropped their agreement to sell Triumphs a few days after I bought mine (how convenient). All the other Triumph dealers around here want to charge me $300 to run a full service and diagnostics with no guarantee it will fix the problem.

Guys, I love Triumph and I love the bike but I need a solution to this. I don't want to dump $1000 into this bike blindly trying to figure out what is wrong.

Thanks,
1LT Nick Davis

Yes, the dealer is BS on this one. My bike was this way new. In my case, the dealer did stand behind it, and loaded a new tune that took care of it.

Since then, I've joined the "derestricted" crowd of Touring riders, so our engine more closely approximates yours in performance.

Please keep us posted on your situation. This absolutely should be a doable do.

The next thing I need to get fixed is the straight pipes. They look good and sound great but, and I never thought I'd say this, they are too dang loud! I always wear hearing protection but still have a headache if I ride more than an hour. Maybe I can fix some baffles in it or something. If anyone has any thoughts I'd love to hear them.

Suggest you do a search on this site for "Exhaust". Much depends on your goals.
I saw someone selling a stock setup here recently, and the sound and performance of the stock exhaust is just fine.

Some folks just can't help tinkering, and there are a number of options.
