derestricting an 1988 VFR 400r NC24

I have heard there are some simple ways of derestricting these, anybody have the know how to pass on? any info much appreciated!!!

 

It depends on the type of restriction, the one that limits power to 12kW (33bhp) is a restricting washer sat in the rubbers that connect the carbs onto the inlet throats, take off carbs, take out washers, replace carbs to find bike de-restricted.

These bike however, can be restricted by a speed limiter (for the Japanese market, to roughtly 118mph), this involves some contact in the speedo unit. Once it reaches the limit speed the needle or whatever gives a connection and the two rear cylinders have their spark cut. There are a couple of way to stop this, but let me know whether it's the restriction or speed-limiter that you're having difficultly with.

additionally the CDI box has restrictors, you can get a replacement Derestrict CDI FOR HONDA VFR400R/K NC24 NEW IGNITER on eBay (end time 01-Jan-10 08:14:38 GMT)

Welcome aboard, Tim.
Any pics of the bike you'd care to share?
400s are kinda rare around here.
