Don't think they're restricted - that law only came out in 1989, so anything before that was full power from Honda. Confused

i,ll go along with dave. my mc16 has no wiring mods, or anything like that.it has some holes in the air box lid, some gp style pipes and a re-jet for a little more power Very Happy

. when i get my standard bike going i'll be able to compare the two.
nice to have another 16 along!

They are only restricted in the way that they have dinky little carbs, restrictive port design, and poor performing exhausts! All consequences of the MC16's production era I'm afraid!

The ignition (although not great by today's standards) is not limited however, so although you would probably benefit from an MC18 R2J/R4J harness/PGM, it should be sufficient for a tuned motor still.

With some porting work, optimising of compression, MC18/21 carbs/manifolds, and some expansion chambers, there isn't any reason why the MC16 can't produce power similar to that of the later models.

Race expansion chambers will be the biggest issue - not many around these days!

Biggest gains on the MC16 would be made by upgrading the suspension, tyres, and brakes! MC21/28 SE/SP adjustable forks will drop straight in, allowing the use of the later rim and brakes, and I'm sure (but this is pure speculation!) an MC18 rear swing-arm could be grafted on pretty easily. If this were the case, the MC21 17" wheel then slots straight in to the MC18's arm!

Ask Nigel Moss what a 40hp RGV250 VJ23 with good suspension, brakes and tyres can do against 55-60hp bikes on a wet track... he was only in that very position at the track-day in Llandow last Saturday!

back when I had a mc 16 it had no speed restriction and when I stuck on a set of free flow scilencers and mc21 carbs it had heaps of power and would easily reach 200ks which was redline in top gear anyway , after it blew up cause of a blown head gasket I put mc21 cylinders on it cause that was what I could get and they made no difference , the bikes main downfall was not power but tyres
