Remus exhaust, does this require a bike retune?

[ade the blade]

Thanks all for the reply's. I refuelled with 98 Ron unleaded this morn because speaking with a guy last night, he experience similar probs with his car, would appear certain petrol stations are supplying not so pure petrols.. after a 15 min blast to get the fuel through the engine... what do you know ?? problem gone...
I would like to take this opportunity to apologise to anyone who i offended by suggesting i was going to put the stock exhaust back on.. i must have been feeling ill or something lol :lol

well done mate for getting your bike back to rights .......now get in the corner and slap your arse with a manky mackerel whilst saying ` i must not even think about silly things like that ever again :lol :lol :lol ...failing that, i should imagine clive ( crh) would be willing to help you out.........( shhhhhhhhhhhhhhhhhh, he`s into all that weird crap ) :rollin :rollin :rollin :rollin
