    Temps made it to about 50F today, the roads were dry, so I was able to manage a thirty mile romp on the Thruxton to get this new year off to a proper start...

    I used to LOVE my New Year's Day rides. May 2020 provide you with miles and miles of smiles on that great bike...

    I never went over 90, either. Not once!

    That is a sexxxeee bike. Love the pipes. How baffled are they?

    Is that one of the twins with the 270-degree-firing crankshaft? I think I read somewhere that some newer twins were doing that...only had 180 degree (CB450K) and 360 degree (XS650) myself. Would love to hear a 270 sometime.

    Is the GT750 you posted about awhile back streetworthy? Reading that thread made me miss the sound of my old GT380...

    Good on ya! Nothing but sun and similar temps here (10C), but circumstance meant no ride today. I will be riding to work tomorrow, though, and any other day there isn’t snow on the ground. Which is most days here.

    Sooo jealous. If I could get off this mountain, the highway is clear and dry for a romp. I'll probably have to wait until April though. Thanks for the pic. Enjoy and be safe.

    Yes, these have the 270 degree cranks, and are supposed to be inherently smoother than the earlier Triumph twins, which had 360 degree cranks, and it does seem to be. They sound more like V-twins than th e classic British bikes, and personally, I find that unfortunate because I've always liked the distinctive noise the older Brit twins made.

    The exhaust on my Thruxton is stock, and as such don't make a lot of noise, but the bike does make a bit of a satisfactory roar when it's wound up a bit.

    My GT750 is 'on the table' waiting for a bunch of upgrades, new parts, paint, and a ton of cleaning and polishing.

    I bought a complete, new, Delkevic reproduction full exhaust system for it from a maker in England, and will install it on the bike in the spring.

    Beautiful bike. Miss my Daytona, I think a Thruxton would be a nice replacement.

    I haven’t the resources for bikes nearly as nice as that, but I always have a bike. Any day on two wheels is a good day.

    Very nice, and a nice bike to do it on. Had a little ride myself today, but on a much less exciting Honda.

    I guess it makes sense that a 270-degree crank parallel twin would have a similar exhaust rhythm to a 90-degree V-twin. Interesting.

    Is the new GT exhaust still a 3-into-4 arrangement? That photo appears to show the center headpipe, split to feed the two lower mufflers...? Looks like really nice chrome plating and seams, nicer finish than what I remember from my 380.

    I saw photos once of a custom GT750 with a chrome 3-into-1 headpipe feeding a single expansion chamber. I’d never seen cylinders sharing an expansion chamber before, and wondered how well it worked. Probably a compromise so they could retain the centerstand or passenger pegs or something, by not having to hang three chambers off the bike from somewhere.

    The Delkevic repro system is a complete 3 into 4 system that is identical to the original stock exhaust. Right and left outside muffler/headers, a center header with the 1into 2 split, and the two inner mufflers that connect to the center header.
    IMG_20191206_085922385_MP.jpg

    It is meant to exactly replace the GT750 exhaust from 1975 M models through the 1977 B models. They do not currently make a repro exhaust set for the 1972 or 1973 GT750 J and K models, though they supposedly can be fitted to those two early GT's, but will not be originally correct for them.

    I remember the 3 into 1 Chambers for the GT750's from back in the 70's, I think the brand was 'Strader', or something like that.

    I found a couple photos of a Strader 3-into-1 system on a '75 GT750...these images are from 2013, the owner was offering them for sale for $600 at that time.
