    Ahhmm

    As I am currently travelling the rocky road of carbs and even exhaust particularly related to my own T150V ~ and as I have considered the T120 Mufflers on mine currently ~ the issue of lack of back pressure/s has been thrashed - yet again- ~

    I ask would a 3-1 as referred to herein ~ so many are race bikes ~ is this what you are looking for ~ Is it an issue?

    As I see it and have been lead to believe, some of element of back pressure IS an issue ~ But as I see it back pressure at low, bottom end is not an issue !

    In fact my T160 when I sold it ~ the buyer asked why the bike woudl only do 95 mph ~ (the fact was that the Police officer that bought the bike boasted he was bound to be the gentleman rider, never stretching or thrashing the bike ~) ~

    I suggested that the custom made copy black caps were a concern even when I fitted them as the actual caps were obviously far too restrictive at speed!

    Nah, them's milers, dirty flattrackers, before H-D had the AMA BAN more than 2 cylinder racers - have another view of On Any Sunday, you can sure pick them 3s.
    As for back pressure, the less the better, uncork`em, & as Matt has pointed out previously, the original 'Ray-gun' mufflers were stylised fish-tail megas, gave best power for production [although I`ve never seen a Hurricane dyno chart], but open works best if volume is not an issue...

    I agree in hindsight ~ No front brakes ~rugged tyres ~
    I have seen this photo many times before ~ I did some searching this morning before work but have not nailed the details ~ as yet ~

    Bike mag tested a Hurricane in `72, got a 13.3 sec 1/4 mile, anyone know if the 3-3 pipe set up lost power anywhere?

    That Rob North belongs to Steve Robins Aka 'Snibor' across many sites ~ in Brisbane, QLD Aust ~

    I have even slipped the left leg over this very bike ~ The small size of the bike is stunning. it is really compact and this photo belies the size of the bike ~

    Steve has only the kick start and I can assure you that bike does bite ~ Steve runs 11:1 CR

    Here is a link I recorded last year `

    Here's Steve's '74 Trident with 3-into-1, from my late friend Malcolm "BritBodger" Dixon's estate, sitting in my garage 'till he comes to pick it up in 2014 during the BSA rallye.

    JAW

    YOU ASKED FOR IT !

    This clip is ^%%*&&^ AWEsome ~

    Turn up the speakers ~ be aware though any non Tripler fans amongst us may just be converted !! FOREVER !!

    [video]http://www.youtube.com/watch?v=-f_FPjfBrWw[/video]

    (On the down side ~ Mate, Steve aka Snibor has one of these and he reckons he has to wear ear plugs as the fuel tank is so narrow the tappet noise which 90% of triples are renowned for ~ is deafening as the engine protrudes so far past the actual tank!! With that in mind he prefers the Rob north as his commute bike!! )

    Actually I was talking with TTRest aka Garry in Brisbane yesterday after my successful test ride on the Trident and he was saying ~ which I well was aware of ~ that the Triumph BSA factory race bike mechanics spent a LOT of time cutting and tuning their 3:1 zorst systems and they made it into a fine/ precise art ~

    Great S.S.S., Ta.
    From Classic Racer Mar/April `12 , Don Castro feature, P.43; Re those miler Triumphs:
    "We were turning those Triumphs to almost 12 grand, & it would run from 2,500 all the way up to 12,000."
    Carillo built his mills, including the rods, naturally..

    Hi
    I suspect the quoted 12000 RPM may be a tad overstated .. a bit of tongue in cheek perhaps :) ..

    It’s just not possible to spin up to 12000 with the valve gear and geometry on the triples and would be pointless
    as Max HP even on extreme tuned 750/850 triple engines is around 8500RPMbut will still flat line at Max RPM to about 9500RPM .. on a stroker quite a bit lower revs for max HP but bags of torque on a stroker..

    here's a clip on the Dyno of the Manx R3 we had over the island this year ... not a silly tuned engine ... specifically built to withstand the punishment of the mountain circuit .. produces 87RWHP at 8250 but carries 87RWHP right through to 9000RPM and beyond i would think but 9000 is plenty on a dyno and scary as buggery to listen to ...
