[fostersice]

been out to day and have had the bike miss fireing on me

went out at 10am had a race around for about an hour the met up with 80 other bikers to by a ride by as one of our friends is dieing and he asked if we would ride by the house,

so we all got to get a met at a place then all headed to his house going though the lanes i used my bike to stop cars pulling onto the roads ahead of the pack

after 20mins of slow riding and stopping traffic bikewas getting up to 100 on the temp and started miss fireing,

i only fitted a decat to it just before we left could that be a problem

i had the bike tune to 167 at the rear wheel
with
dt-1 air filter
scorpion carbon race cans
pclll and o2 sensor blanks

would fitting the decat mess it right up so it miss-fires??????

just never had that prob before and bike ahs only do 1000miles

thanks for any help given
