Does it depend on what the replacement unbalanced pipe heads look like? Can't be certain of their heritage (750 or 850, MK??)? I have never removed the existing locknuts so don't know what is underneath and if compatible with replacement pipes yet.
Re. Re-jetting, yes, that will be addressed as will opening up the heavily muted rear exit points for all the LOUDNESS ;-)
My understanding is that the balance pipe helps reduce back pressure when the silencers are heavily restricted with mutes. Running non balanced pipes with the MKII muted silencers would be a lot more restrictive...basically 2x as restricted...since one silencer per one cylinder exhaust path, instead or two silencers per one cylinder.The separate downpipes are louder than the balance pipe ones
So give it a try first before you mess with the silencers
Of course it all depends how loud you want the bike!
Be warned it's not unusual for downpipes not to fit right on commandos, make sure nothing is under strain when you bolt them up
Yes, but Mexico Mike told me in another thread this cutting out the welded mutes was a common practice back in the day. My silencers are not in great shape to begin with so I'm not sweating over mucking them up.Sounds experimental but good luck to ya.
If thine mutes offend thee pluck them outYes, but Mexico Mike told me in another thread this cutting out the welded mutes was a common practice back in the day. My silencers are not in great shape to begin with so I'm not sweating over mucking them up.
Biggest disappointment was the nice new RGM Stainless roses (063555S) although longer 3/4" thread, the thread diameter is too small for my R10 head! The roses just slide right into the head ports without any threading!
Reviewing the older threadlines on these nuts, could not find any mention of a difference in diameter, just the 3/4" vs shorted 850 balance pipe type.
Anyone know whats up?
I went ahead and return to service the original beat-up/bent-up roses, using RGM's steel sealing washers and high temp copper-laced exhaust RTV. Got a good solid clamping to the headers. Should be OK to run, no?
