Is there any form of restrictors on the 88 Gixxxer 750? Specs show the bike can go up to 150mph but my speedo shows only 180km/h max(that's about 111mph, a far cry from what's on the specs.). Mine comes with a speed warning light and the dial's set on kmh not mph. If there is, hope someone here could help me out on this. Thanks in advance. BTW, on my last gear the rev counter shows it could only go up to about 7500 rpm, wouldn't go much further than that.

I noticed you are in Singapore.........Is that the country the bike was originally purchased in? If not which country did your bike come from. I know USA models didn't come with a speed sensor. It sounds like the black box is restricting the power/rev limit in 6th gear if you ask me. It could be as simple as changing out the black box with a USA version box.... but that is just my speculation.

Thanks for the reply! The bike's bought in Singapore, but it's a Japanese import because because of its' speed warning light, I think...
Will try searching for the US/UK dials once I have time and dough, Thanks! BTW, u guys think it's a good deal to pay US$950 for a 88 gixxer750?

The restrictor is in the speedo itself on most Jap market bikes of this age. Try disconnecting the speedo cable and see what happens. The ECU probably won't need changing.

the Japanese 750 bikes had by law 77hp with a series of restrictors..

I used to have two japanese Import bikes and both had speedometer restrict which i disconected... some of the late 90s Japanese bikes had also restricted the CDI and carbs.

Good Luck

You should be able to pick up a black box from the breakers and have it work, ie, from a home market (UK) model. I believe it would be 'plug and play'.
