Would upgrades make a restricted bike faster?

[chalky143]

If i put mods on such as a micron exhaust and k+n filter etc help the performance and acceleration of a restriced 600cc for example?

thankyou

Well what you could do is de-restrict it, that will make it a shite load faster.

A restricted bike should make 33hp.

If you wish to make it go faster, remove or, if you only want a little bit of power reduce the restrictions.

Dynojey kits, exhausts and tarty air filters often don't really give that much power for the amount you spend on a fully derestricted bike. Most use for 'tart' value.

If its restricted to 33bhp adding performance mods will make no difference as its still restricted to 33bhp imo

The idea of restricting a bike to 33hp is just that. The bike must be restricted too 33hp not restricted then modded to make a handfull more horsies as then its not 33hp anymore is it?

I really cannot believed you asked this question.

If your not happy with 33hp de-restrict it..its that simple.

Still not happy? Buy a faster bike?

obvious thing-derestrict it.duh
secondly, and more helpful would be to change the gearing. don't affect power but gives loads more thrust-and will give a real kick after the restriction has cut the bikes power out already ( )
but seriously, this was a dumb question. JUST DERESTRICT IT!!

If you add a filter and a new pipe it will no longer be 33hp, so you'd be breaking the law anyway, it would be easier (and cheaper) to pull the restrictors out, or just stay legal for the rest of the period (as i guess thats your intention otherwise you'd have just taken them out already). The pipe will just make it sound better, wont make enough of a difference in power to be noticable.

[chalky143]

this may sounds stupid but i dont know much about restrictor kits but if i took 2 of the 4 restrictors out would that make a differnce?

If you start messing about with it for more performance then it's illegal no matter how much power it makes, some little tweak that gives you 35bhp is just as illegal on a restricted lisence as taking the restrictors out and having it full power. Either leave it as it is or get rid of them completely, you know it makes sense.

If you really want to go that way and not derestrict your bike, an end can is probably your best bet, I found it added more power low down.

In the end I just derestricted anyway.

If you only remove two you will most proberly be neening to spend alot more money on it very soon after to rebuild the engine after you have blown two cylinders up.

If you want more performance eithier take them out or do the mods you wanted to do and get it setup on a dyno.

[Visitor Q]

Dear god, if i see one more stupid thread about restricted bikes from you, i will come round and tea bag you.

So help me god.

And yeh, what they said. Either derestrict, or dont.

Dont fuck about.

If you want an intermediate step, buy a vfr 400, restrict, then derestrict a month or two later, then next summer get a full power 600.

Simple.

Now shh.

Go on a diet or as Brian from family guy puts it...

Hi

Might make a tiny difference, but not really much at all. The restrictors after the carbs pretty much just limit the amount of air that can get into the engine to about the right amount for the power that is required.

All the best
