Hi All
i resently got a scorpion exaust for my yzf r125 and fitted it over the weekend with my mate iv had a couple of rides out on it and it sound awsome but when i have taken it down the eastlacs for a rip it is only hitting 9000rpm in 6th gear i think it possibly wants to be remapped and went to quill exaust and asked them and they said it can't be done to yamaha's at all which has to be a crock because when i got a quote off quill for an exaust they said they would do everything to it including dyno and remapp. then i rang wigan yamaha and they said they dont belive it is possible too. im not looking for loads more bhp i just want it to run right is there anything that can be done
Thanks
