At least you got a brand new looking bike stu with all the mods :devious ive not finished my by far yet :devious Gearing next plus the new jet on its way for the better nuetral change :thumbup
That link pipe looks interesting!!You'll be amazed how good your gearbox selection(no clutch drag at all)is after that little jet goes in.Best mod I've done.Pity you can't do it on those awful Ducati boxes!! AL
Check out the extra short pipe just before the collector to the rear pipe
and the extra length of the 'front' balancer
This is a modified o.e one done by Mark Hill MHP
He told me that the longer crossover pipe was to help with the returning exhaust pulses/waves and that it helped with the midrange dip around 5000rpm and made the bike pull more harder in the low/mid rev range. He explained that the rear header on these bikes is far to short and that the smaller crossover pipe into the collector helped to equalize it (rear header)with the front header and improve the flow of the whole exhaust system. I asked him would spending £1400 on an Akra 2-2 against this mod be more beneficial and he replyed "No Way". Himself and a few others worked on this mod from the beginning and he said that they where amazed at the performance gains it gave compared to standard and also how much it matched a full race system. It was made to offer a cheaper alternative to the guys who where racing Mille's at the time against buying a full Akra system. The only thing to note is that they where using a 70mm link pipe and 70mm end can which was being supplied through Aprilia at the time. He said this gave the system it's best performance. I told him I expected to use a 60mm link pipe and can and he replied that you would lose a few HP off the top end but that it would be a good compromise.
