    Here's the link to the exhaust guy we spoke about today Bill , I'm not sure if he's made any two stroke exhausts but as you'll see from his gallery photos everything he makes is top quality. http://www.aph-performance-engineering.com/gallery.html I would recommend Alan to anybody wanting a quality exhaust system making.

    Just picked up the fuel tank. Got it sooner than I expected and very pleased with the result. Expansion chambers next, fabricator for chambers said he can start on them in the next 5 or six weeks. Think my main contribution in a lot of this are finding such talented people!!

    Got the radiator cut down and modified and rough fit to the bike. Tank has a cap and outlet fitting, next is exhaust. I think the exhaust was iconic to the TR750 so really looking forward to that phase.

    Yes the motor used in the TR750 was based on the Suzuki GT750 motor. The street engine was rated at 67 hp and the racing bikes produce about 120 hp by the mid 70's. I'm going to try for 90 to 100 hp from this one.

    Thanks Mark, the only hold up is money or the lack of it! What silencers do you have on your bike or are they custom made?

    They are hydroformed/rotated 'n welded mild steel and were made by Gibson, maybe 10 years ago, but Gibson were sold, so I'm not sure if the new people (Stinkwheels?) are still making a good pipe?

    She was shown (at the earliest stage of restoration) on the GIBSON website, from where I screen-grabbed these photos.

    Mark, the bike I'm building is a replica of a transitional bike that used a modified street engine. Yours is the real deal ,.................. 500cc racer that inspired a few exotic street bikes . Thanks for posting the pictures. Let me know the next time you race or track day it as I would like to see it.

    Will do.

    I'm hoping to pick up the swing arm next month (still at Harris after they fixed a crack) and get it together for at least the 2 x 2 day Oliver's Mount race parades in summer. Maybe Dalby Hill-climb too if it runs this year.


    I had a big pile of 'Gonna build a TR750 replica" bits, (GT engine, nice wheels, brakes forks, carbs, ignition etc) and a Seeley T500, but sold them all (plus an SP2 road bike, plus a Weslake Triton, plus added to debt, obvs) when chance to get the RG arose.

    Like any sensible person I always wanted to be Barry Sheene in the mid 70s*

    TR750 update

    Just a brief update. Just got the bike back from Justin Roebury who fabricated the exhaust system. Justin had the actual pipes from Tepi's #8 on hand as a pattern. With this and Justin's fabrication skills I'm very pleased with the result.

    Have got the ignition system roughed out, porting the barrel at present. Engine rebuild to commence shortly. With a little luck noise and smoke this spring, will update then

    That left hand pipe's going to keep your knee nice and warm.

    Is it the camera angle or is the bike biased nose high?
    It's very noticeable in the photos without the tank fitted.
