Hi and thanx for the reply.

The bike is a '93 MC21, 250R7L, so it's just the basic spec.

As the bike was cheapish (£400), I didn't fancy splashing out on a new fairing, guess I'll keep an eye on the classified's!!!

I've drained the oil (unknown quality) and replaced with fully synthetic Motul, the power valves are now correctly adjusted.

As for being restricted, the orange/blue wire has been cut and taped back but not connected to anything else, while I am not interested in top speed, what effect would this have?

The GPS wires are in standard form.

If the ignition (derestriction) mod is carried out as outlined in NSR WORLD, does it increase top speed AND horsepower?
If so are any other mod's required (ie carb) to keep thing's sweet.

Thanx for a fab site,
Sorry about the question's I'm on a steep learning curve at the moment, and want the bike running as sweet as possible.

Regard's Phil
