1200 import 1996

Post by Mattheelan » Tue May 19, 2020 8:41 pm

Evening all. I’ve brought a xjr 1200 1996 which I would say is a import. It has a 1300 set of clocks on it. Love the bike. But it won’t rev above 7k. I’m servicing it this weekend. Looking to change the standard exhausts. And will wanna tidy it up. I ride it every day for work. But the 7k is bothering me. Is it restricted in any way. Got a friend who is a mechanic and says if I can find out how to get th revs up. He is willing to help me.
Any ideas.
Thanks Matt

Some info here on the first page, it appears there may be a couple of types of restrictions types on imports, some are restricted by a devise in the head light linked to the speedo, the other is probably via the ecu, you need to determine where yours lies, is it speed restricted, or limited RMP, will it not exceed 7K in 4th gear for example.

There is a post on here somewhere that gives a very good details on how to sort this by, adding a resistor or the likes off, been many a year since I read it, I can't remember who posted it either, try the search on here you may have to troll through.

Thanks for reply. It won’t go above 7k in any gear. Not sure about the speed restriction as not been that quick on it yet.

Be good if you could borrow a European Ecu for your model, not sure if it would be as easy as just swapping it out.

does the tacho needle go up and down randomly when you hit 7k,the reason i ask this had a import ecu on a 1300 a few years ago and when you went over a certain rpm the tacho needles used to go up and down witch indicates a fault ,

No mate. It just feels like a misfire. Rev needle stays normal.

Went and brought a 4pu ecu. Seems to have solved all the restrictions. It now goes like a angry wasp.
Thanks gents
