I’ve only managed to find one Dynojet map for the UK model and that is the standard can / standard filter. Have any other Speed Four owners ever fitted one and had any maps done? My bike came with a K&N filter and a Viper can and I’m hoping to dial out the 3-4k flat spot
Hi Chris, I believe the TT600’s had an issue with the fuel injection system which was erratic. This was improved with the S4. Mine has a Viper can on as well, and a power band that comes in at 3,000 revs and it takes off, which means I have to short shift while going down my road otherwise the neighbours would think I’m being a dick screwing the arse off it. Sorry can’t help you with the power commander as I don’t think mine needs it but like all Triumphs everyone is different. Hope you manage to solve your problem as they are lovely bikes to ride.
