Daytona flat spot at 5k

Triumph Motorcycles Sports

Hello,

Just joined the forum and just bought (last week) an 05 Daytona 955i.

Been out for a couple of rides to give it a bit of a shakedown and noticed a flat spot around 5k, it has an after-market can/exhaust, so thinking it might be that.

I know it was a common fault with the earlier models, but wanted to check if anyone else has had a similar problem with a gen 2?

Thank you,
Johnny

Hi and welcome @Johnny

I have a gen 1 Daytona T595 and have seen this issue on and off. I know you asked about gen 2 owners but there are a few things I have tried that might help, and I don’t really know if just one of these contributed or fixed the issue last time.

  1. Replace stale fuel
  2. Split or perished vacuum hoses
  3. Replace fuel filter and check fuel hoses
  4. Check ECU for errors (I use TuneECU)
  5. Remap for aftermarket exhaust or put an original exhaust on to eliminate this as a potential cause
  6. Check/reset Idle Air Control Valve (IACV)
  7. Reset Throttle Position Sensor (TPS)

Good luck :crossed_fingers:

Welcome, Bienvenue! Geoff nailed it. Aftermarket exhaust means the ECU version map needs to be checked.
