Called my local dealer asking about a stage 1 kit for my bike. I already have a TFI, only got a couple of mos left on my warranty so am going to install stage 1 and SE II slips ons. The guy told me it was a requirement that I buy the SERT as part of the stage 1. Said all EFI bikes have to have the SERT. I told him I already had a fuel management system and didn't want a SERT. He then STRESSED to me it was required with EFI bikes. Jeeez, told him forget it, I'll get my stage 1 kit from someone else..THEN he changed his story..."youalready have fuel management, ohhh, I didn't hear that, then the stage 1 is 139.00. Kinda disappointed as this dealership as always done me right in the past. thanx for listin'.
