I have just bought a 1982 750 Seca. Is it possible to adjust the throttle response curve for fewer rpms per degree of twist? It feels just a tad too hot for me.

Added later: I don't think this adjustment can be done. Am about to get used to it
as is.

Also, can someone tell what is the best owner/repair manual for this bike?
XJ750 Seca, 1982

The best guide you can find is the XJcd it can be found Here

Thanks for the tip, will order asap.

You could try putting restrictor plates between the manifold boots and the engine, but you sure would take a lot of fun out of that machine.
