    I bought many parts for my '56 T110 from Ace Classics in London and was very happy with the fit & support from the team over 2+ years
    The Ace team is really knowledgeable and Kev does a great job in packaging up for export

    These http://www.totalbikebits.com/ zoorsts are O E M quality , chrome & fit . need to google for Wassell Stockists . They do fearfully not quite so quite long megas , AND 1 3/4 pipes , too . In fact 32 in 1 3/4 headers . . . . Er . . . . Ah . . . .

    :mrgreen: :lol: :x Id be checking out actually If it WAS 1 3/4 pipes STOCK on it , as acoustically theyre a sound for sore ears , as the ' gong ' strides down the British Steel tubeing createing a musical resonance whilst flexing the walls . . . . . .

    Looks like it needs someones boot on yr left one while free at rear and stay , to get it up under the primary , perhaps .

    Thanks for the replies.
    Ace Classics seem to have Tiger Spares parts ?


    Are the parts made in the USA or UK ?

    I stripped the engine down yesterday.
    Case is punched out at the left hand main bearing.
    It has a one piece crank but will need regrinding.
    The cylinder could be replaced due to a bodgy top fin repair.
    The head is in very good condition for its age but it has the usual cracks valve seat to hold down bolt holes.
    Four cracks to the outside of the casting.

    It might be easier to find a 9 stud top end but will look at having the head spigot-ed or maybe a weld repair and unleaded seats as the TR5T got.
    The transmission is not bad,can later gear sets be used in the pre unit case I wonder ?
    This is my first Pre Unit,a great old bike but it is going to be an expensive build me thinks.

    Ged at Skye Classic Motorcycles specialises in Triumph.

    He only does quality stuff, he can be a bit snappy but he knows what he
    is talking about and is an OK bloke.


    Well is is an OK bloke even tho he sells Renold :D :D :D :D :D :D

    Thanks Andy.
    This Pre Unit thing is a whole new ball game as far as parts go.
    Look up Norton Commando on eBay (worldwide) and there are plenty,pre unit Triumph and it is slim pickings.
    I stripped the head,the hold down bolt holes have been spigoted already,the seats look over cut though which is a problem.
    In their wisdom Triumph elected to use cone shaped valve seats that are placed when the head is cast so they can not come out.
    That (can) leads to cracking from the valve seat pocket out to the bolt holes.
    Perhaps the head needs to go to 'The cylinder head shop in the UK. :?
    I will stick to Nortons for the rest of the week,Madass rim laced up this afternoon to a eBay rear hub. :D

    Beware there are a lot of crap remade bits from dubious manufacturers being sold as ONS.

    Look at Skyes web site.


    I see many "Triumph" specialists at the shows at least Ged is open about where he gets
    his parts and most are good hense the price.

    At Netley a guy looked at his racks then went and purchased a cheap thing from another Triumph
    seller. He then came back to Ged for the fixing kit..........gues what he got told to do.

    Theres ' a few ' variations on the P. U. heads , as in thickening of the castings . The later ( 61 ) are unlikely to crack unless roundly abused , as many are . :(

    750 Valves ( 1 7/16 Ex. & 1 9/16 In.) will likely fit out on the seats , getting them near proud in the chambers , essential for real performance , with a little judicious porting work .

    Ordinarilly youd steer well clear of a cracked head , however , valves will recess in standard seats , so hardened seats, in. & ex. are worth fitting . Theres a chap in Sydney just turned 70
    who doesnt know you cant weld alloy heads , so if its cracked , if you send a P.M. , I will put you in touch with him .

    Shentons book on Triumphs is essential , if you want it to do what it auta .

    Matt, I'm wondering about this comment. The other day I was talking to my friend about his fast Triton, and he said that he believed the standard size port in a 650 Triumph is on about maximum dimension. I tend to agree with him, and his bike certainly proves that building for increased torque and higher gearing works well.

    I'm with you there. I got 750 size inlet valves fitted to my T110, which already had E3134 cams.

    The big valves were a tuning step too far, for road use. Midrange pull disappeared and riding in slow traffic and idling and reliable starting were just no longer on the cards.

    As I'm too lazy and mean to strip the engine and pay for new smaller valves and seats, I tried advancing the inlet cam, which made little difference and then tried opening the inlet valve clearance to 8 thou, which has helped a lot.

    Back at the campsite , there were 20 blokes collapsed aroud the Bonneville .
    " What had I done to IT " ? " No One cpould START IT " . :lol: :D

    Nothing , started third swing . Power stared aroud 25oo & ' Came In ' in the mid range , and keep coming inner & onner etcetera .

    JoMoCo Valves were 1 5/8 & 1 7/16 in . in a T100 built before 1963 . JoMoCo springs were W&S , as per Norvil Race Shop P.R. Commonanado .

    Yea , vehicals tend to be a bit obsticular in town , and its a bit flat down low . But Bonne's are a bit flatter down low with the Twin Carburators
    thus its Flat Twice as Far . But with a REAL Clutch - Cork , it feeds in clean & smooth , better than the Std. Injun . But let a hole evolve forward
    before applying apparatus - Just Like the Commando . My Commando anyway . :D

    Saw a HONDA XR drive aboard / atop a VW bug , pre ' toned ' days on the Bonevel . Decide I did not wish to emulate this feat . HOWEVER ,
    Easter Show & the 4 lane Balmoral Road & the Pointsman , on the third day with the heavey traffic , Id given him a meaningfull look as Id pulled up .
    And a FEW MORE as thered been brief gaps in the traffic . Exasperatedly selected newtral with the blip , observeing gearshift . And Looked Up .

    The Kind Chap was waveing Me Trough . A quick blip and a grauch , :oops: and Chocks Away . He DID appear to have a funny look on his face at this stage.
    As I pulled into , the Er. . . Gone Gap in the unimpeded Four Lanes of Traffic . Appeared to have his knees knocking then. Sorry - Couldn't Stop .
    To Much Traffic . And If I had Beside Him there would have been a Traffic Jam . Just one of those things . But LOOK before You Leap . Particularly at TRAFFIC LIGHTS .
    Some People think the advisory like the posted speed signs . In Sydney you Look in Your MIRRORS at ORANGE LIGHTS . Often youll get run over or into if you brake .

    A evening ago I was a bit indecise at the Orange . Just About Slammed on the Brakes the instant it Oranged . Laden Semi & Trailer folled me Through .
    They don't pull up , or at least ' Hook Up ' Quite as Quick .

    Anyway . P. U. T 120 Ran 9.75 : 1 & 1 5/32 monoblocks , and the pipes came in L O U D at about 7400 , cruising in third . Then there was no stopping it .
    Borrowed by a mate , it ran to 90 , then ' the fastest bike on the Shore ' ( Brian A65 ) was so far aft it was no contest . So Im Told .
    'Can I Borrow the Bike ' ? ( One of two riders of my acquaintance Id thought at that stage not accident prone )
    " Don't Take It Over 90 In Third " . Kevin .

    Basically its not doing less than 10 mph , with the clutch In in 1ST . Solo on Gravel itll light up from there , or lift up Throttle Past half .

    Check out the T.T. Spec . Perfectly sutable Road Bike . :wink: :)
