Suzuki 750 jetting

[Islandstar]

I've got a Suzuki gsx750 Inazuma..not a common bike, that was sold in the UK. I'm hoping to put on an aftermarket exhaust, and would like some help with the jetting. I'm not sure if its a similar set up as the older GS750, so hoping that somehere might know and put me in the right direction. Thanks in advance

I would check over on the GSResources - while the bike might be rare, the engine (and modification of the intake) is not.

The Inazuma's run the oil cooled motors descended from the first gen GSXR's. They have very little (like nothing) in common with the older GS aircooled motors.

I'd be betting they are tuned the same as the Bandits - and GSXR cams, carbs etc would pretty much be bolt on.

Look at 1988~2007 Katana, Bandit 6~12 and 1985~92 GSXR for information
750 will probably need about 10~15% larger main jets.
Keep the stock airbox or it will be 'lumpy' when cruising around and pulling off from lights/stop signs, etc
The bore spacing and main bearings are the same on majority of 'oil boilers', the crankpin diameter and placement changes with bigger motors (1052, 1127 & 1174cc)
Eventually I'll drop a 1052 top end on my 600 Kat, already collected most of the parts 8)
I don't know anything about the 1400, they never made it to USA
