Tank Slap - Motorcycle Forum

¬For the last 2 years, this bikes been off the road. Had running issues before I garaged it and seem worse than ever now.

Bike : Triumph Daytona 600, K&N Air filter, TORs exhaust end can and matching TORS map.

Symptoms : From Cold it struggles to start. Cranks over fine, but does get going for a good few seconds. Revs hunt and idle pretty low. Pulls away hesitantly, often feeling like its bogging down, then all of a sudden picks up. Quite often stalls when pulling up when cold. From hot, it’s even harder to start. Rev’s sit extremely high at idle (1.5k-2.0k) The bike actually pulls like the throttle is open!

Checked : New air filter, oil, oil filer, fuel filter, higher octane fuel, engine flush, throttle body rubbers. Bought a cable to check the map on TuneECU, but having issues linking to the bikes ECU.

Been a problem for a fair while, but it’s getting more and more frustrating! Appreciate any help you can shed on this!

Have you tried it with the standard air filter and the stock exhaust on it?

Might be the throttle position sensor, which unfortunately you need TuneECU to adjust.

Have you had your valve clearances checked recently? Poor cold starting can be an indicator that they need adjusting.

Yep. Triumph put the old map back on too as a check

My thoughts too. I doubt they've ever been checked in 21k

When Triumph put their map on to test it did they take it off afterwards?

I believe so. Again why I'm so keen to get my TUNEECU cable working

Mine needed adjustment at 12k and were checked again at 24k and didn't need any. Up to 40k now so I probably won't bother again.

If you're certain they've never been checked I'd say do it anyway. Also might be worth getting the throttle bodies balanced if you haven't already.

No certain, but I bought the bike on 12,000 miles. Dealer said it was checked, but always had my doubts

TPS or the throttle bodies need balancing, both of which tuneecu will help you with, however you will need a carbtune to do the bodies properly.

Need to find someone local with a working tuneecu set up then! Doh!

Where are you?

Hemel Hemsptead / Aylesbury area

If you can get over to Billericay I have the cable and TuneECU

Cheers for the offer dude. Bit worried its the obd on the bike rather than the cable though.

Ill have another go on a different laptop over the weekend

If Triumph could connect to the bike when the map was changed the OBD plug and wiring is likely to be ok, as they use that plug to connect as well.

Fair point!

Bikes still being a royal PITA!

Every time I start it really struggles to fire up. Today though....once I got riding, the speedo just sat at zero constantly.

Anyone seen/had that before?

Time for a new one

Crossed my mind many a time mate!

Just can't bring myself to do it.
