I'm looking at buying a new end can for my NC23. I want a bolt on one and have been looking at two options.

The first is one of these.

The second option I have been looking at is one of these either in Oval stainless or carbon fibre.

Has anybody had experiences with either, good or bad?

Also, there's no mention of manufacturer or photos on the second one.

Any advice appreciated. :)

Either way, add the cost for a dyno set up and jetting. Dyno will sort all that out using Honda jets or another make

They all seem to say you don't need to re-jet the bike...? Or am I being naive?

Rejet and you will see and feel a big difference. It will probably run ok without jetting but anything to do with the zorst, can, airfilter should be checked on a dyno.

Ok, thanks.

I don't know if it really makes any difference but the bike is 33bhp restricted currently. The main reason for changing it is the standard one is very quiet and is looking a bit dated now... A new can would just tidy it up a bit. In this case, I presume re-jetting it would make no difference as there would be no performance gain anyway? Or am I wrong just for a change?

If you put a can on it it may put it over 33bhp
Chances are if its not been done on a dyno, it will run roughly anyhow

Really?

I was under the impression that fitting the can would not take it over 33bhp as the power is limited by the washers in the carbs. I presumed that whatever you do to the exhaust, the amount is fuel/air mix allowed into the engine is still limited to and amount whereby no more than 33bhp is produced. Is that not right?

I mean on the bike as it is, the standard can is not hampering the performance, it's the washers in the carbs so surely fitting a less restrictive zorst will still not allow more than 33hp?

I don't want to do it if it is going to boost the power.

Did you mean it might run roughly with the new zorst or as it is currently. I've never ridden it unrestricted so have nothing to compare it to but it runs nice and smoothly.

Anything to do with air filter, down pipes or can will adjust the bhp. You mayu lose or the bike run like a bag of spanners or it may run better. Any mods or replacements should be at least checked on a dyno. End of the day, you have a 33bhp certificate and that keeps you legal. If its gone up 2bhp I am sure you could claim its a different dyno and some have optimistic readings, but if you want the bike to be SMOOTH through the revs and gear, get it dynoed
