For christmas I got a big one exhaust to replace my blowing stock front pipe, Yay or so i thought!
Since it was fitted my bike has ran like balls, top speed has gone from 81 to 61 mph and has lost power throughout the rev range. Before I fitted it, the bike had power throughout the revs and was quite nippy, now it just has no power until 8k till 10k.
It no longer has 6th gear, change from 5th at almost 11k (won't rev higher... is that normal?) and it just bogs down. No acceleration, no power, no revs increase and are forced to change down.
Does it just need rejetting or what? I have no clue and don't want to pay some theiving mechanic!
i would think i would want jetting as i put full dep system and when from 240 main to a 310 main but a few people say u dont need to so for £20 for a pack of mains i would give it a go
