Danny,
I haven't touched the exhaust duct but from when i fitted the lomas pipes i think that the exhaust flange hole is the same diameter as the exhaust duct so i won't have a step. That is something i will look into. Cheers for the pm with the link to the reeds
Mj,
My barrels are kr1 with a stage 3 tune of some sort bit this tune was done a long long time ago as the bike hadnt been taxed since 99. The main exhaust looks to have been raised slightly and so do the transfers but not by alot. The kips are still quite small so i think it might be this which is holding the revs back. There is a big mismatch between the kips duct and the powervalve on the cylinder side where i didn't have a decent enough tool to match the kr1 kips tunnels into the kr1s valves.
Jetting wise with 155 mains i was still jetted safe as i plug chopped and it revved on till 11250 but the midrange is much fatter now with 162's and i've only lost 250 revs.
This is where the electronic powerjets on the new carbs will come in allowing me to keep the fat midrange and gain some overrev by leaning off the jetting after peak.
I have some 1s barrels that have been strengthened by bdk at the back and they look to have had some porting done too, after a replate they will be going on.
Howie,
Do you know if you are running 1 barrels and pipes and ignition?
