[quote=Dangerous Dave;1639370]keep the wadding in place too otherwise it sounds tinny and hollow.

haha as an experiment yesterday (b4 i read that reply) i took the wadding out and i actually love the noise it makes, doesnt sound tinny with my beowulf, sounds like the bike without a pipe only a tiny bit quieter and doesnt make the stupid whistle sound my bike makes without an exhaust all together!!!

I think il keep it like that for a while, only problem is its making my bike run slightly too lean now, i countered that by putting the choke on the tinniest ammount... i may have to see about changin the jettin when the pays in, though i did about 25miles on it between yesterday and this mornin and its runnin alright, just if the choke isnt borederline-on the bike stalls n dies when i open the throttle

What, left the perforated tube in the can too?

Won't do power much good, as I understand it you need to either run a straight through, or a packed can to stop the gas resonating about inside.

yehh im considerin takin it apart again soon n takin teh perforated tube out as well, might help get the fuelin bak to normall, tho it is still running fine with the tube in! need to get some more rivets before i have another go though!!

They run crap with no tube at all, just acts like an expansion chamber in reverse. Sounds naff too.

haha oh right fair enuf!!

I am gonna do a trial with the 650's Akrapovic system on the 800 and see how it works, the 800 could do with a few spikes ironing out.
