wraith Posted April 1, 2017 Share Posted April 1, 2017 Ok, don't tell me off for this but which gsxr750 barrels fit a mk1 b6 ? Thanks. Quote Link to comment
canamant Posted April 1, 2017 Share Posted April 1, 2017 long stroke ones, 70mm bore. GSXR759 FGH (65/86/87) or 1990/1991. Also later 750 teapot had a long stroke 70mm bore. You'll need the pistons too ! 1 Quote Link to comment

Oilyspanner Posted April 2, 2017 Share Posted April 2, 2017 I'm sure it's the case TD - TTS used to do various big bores for b6, 750, 884 , you didn't need to change the head, unless you wanted the better breathing provided by bigger valves and cams. It completely changes the character of the engine, from limp and revvy to torquey, with max torque and power achieved at lower revs. I've just got out P.Bikes mag from Jan. 1996, it has a feature about just this and it states that even the 884cc conversion can use the b6 head - as the late great John Robinson says - big bores effectively lower the state of tune, shifting the peak lower in the rev range. When I got into O/C bikes I put all the mags with useful articles alongside workshop manuals in my ' library' - sad but true ! - comes in handy when doing things though - my wife keeps cluttering the shelves with random books though . . . 1 Quote Link to comment

Cheers for the replays and not bumping it off Quote Link to comment
