SLR 650 Exhausts / Restrictor kit

Hi everybody,

I'm thinking of buying a 1999 SLR tomorrow, but i want to buy a set of aftermarket exhaust pipes for it but i cant seem to find any about.

Does anyone know where to get a set of stainless exhaust pipes from?

Also, as i am on a restricted licence, i would need a 33bhp restriction kit. Does anyone have one for sale? I expect it would also be the same kit for the Dominator.

Any help would be much appreccciated.

Thanks,
Rob

Welcome to the forum,
The restrictor kit must be fitted by the dealers and have the appropriate paperwork for it to be legal.

aah... okay i heard that there is nothing in the law that says who it must be fitted by etc, and that a dyno sheet would be sufficient proof that the bike is restricted if the police / insurance company were ever to ask.

THAT IS PUT ABOUT BY THE RIP OFF MANUFACTURERS i spoke too devon and cornwall police about this a couple of years ago, there is no legal requirement as far as they could tell to have anything other than the restrictors fitted, dyno read out would help. dyno it before fitting after market exhausts though, i think germany had the SLR restricted to 33 bhp as you see 27kw cdi,s on ebay there

hi there,
your exhaust is most likely stainless steel, try rubbing them down. if i remember right, the restriction on the slr is done by moving one cable on the cdi unit. otherwise there is no difference in the cdi to the un-restricted version.

ok thanks for that, my dealer says that they can restrict it for me, but for an extra £200! What wire do you move on the CDI to make it 33bhp then? That sounds like a much cheaper alternative to paying the dealer for it.

Thanks everyone.

i am attaching a drawing from honda germany, it is in german but it looks like that only positions a + b need to be swapped.

whatever you do is at your own risk - i cannot be held responsible if you fry or mess up your bike!

be careful when moving the cable as not to damage the plug.

good luck

ps: maybe i should supply brief translation:

description:

the model honda slr 650, type rd09 is offered to the market in two different power modes (engine power 25kw and 29kw).
the difference in engine power results from the use of different spark units and changed cable positions.

a specialised tool has been developed to remove the cables from the plug.

please don't try to remove cables with a screwdriver as that could damage the cable and the plug.

to change cable position proceed as follows:

remove the lid of the cdi plug

lift the lid carefully. the lid has four latches that can brake easily.

change the position of the green cable

depending on the model move the green cable from a to b (29kw to 25kw) or from b to a (25kw to 29kw)

wow, thanks for that, it looks kinda easy so i'll give it a go. :p

If that is all you have to do to them, what do F1 international supply to restrict the bike then? surely they're just restricting the inlet on the carb when there is no need.

sorry, and how d i find out if my bike is a type 'rd09'? it is a 1999 model registered in 2000 on a 'W' plate.

are the UK and germany cdi's the same, or would i have to get hold of a german unit?
thanks:toothy7:

a slr650 is a rd09
have a look here for explanation.
i can't imagine that cdi units in europe differ, have a look if you can find the code '4E6A' on the cdi
since i don't have a slr, i have the fx which is the later model, i haven't tried if it works. but since that info is from honda it should be reliable.
if you do it yourself you will have to get all the paper work sorted - i don't have a clue of whats involved...
why don't you ask a honda dealer of whats involved when restricting the bike?
good luck

tbh i'm pretty reluctant to pay £150 on top of what my honda dealer is charging me for the bike, just for the restriction kit.

The cdi trick seems great and i'll be able to get hold of one of the pin extracting tools if mine is the same cdi, so it should be okay.

I've done some research on the internet, and it seems that the 33bhp rule is not regulated atall. there are no rules as to how the power output is measured i.e. at the back wheel or the crank. there are also no rules that say you need any documentation to prove that the bike is 33bhp, and there is no rule that, if you do fit a kit, it should be fitted by someone who is 'approved'.

it seems that f1 international, who import the restriction kits, are making a lot of money by selling worthless pieces of paper that are not actually required by law. if they only sold the washers by themselves, they would have gone bust a long time ago, because the restrictor kits cost pennies.

i have the info from a german forum where the slr, fx and fmx are a lot more popular than here. seems to work for them.

do you know if they have the same laws in germany regarding how much power you are allowed after passing your test? otherwise, i couldnt see why they would need to be restricted to 33bhp atall.

also, can i have a link to the german forum? it might be useful...

thanks! :D:D:D

okay, thanks for that, it seems that in ermany, they need the TUV approval, whereas over here we need no documents whatsoever! great!

everything in germany needs tuv approval, you are only allowed to use specific tyres or of course replacement parts as long as they have e-numbers. if you change the cdi it needs to be recorded otherwise your bike looses its 'abe' (general approval for road use). if you change shocks, carb or want to customise your bike you need the approval of the tuv. on top of that they check your emissions, so no richening up your mixture for better acceleration and noisy pipes are out too.
i am glad i don't have to put up with that any more...

i just realised that you say the power is limited on the german bikes via a different spark unit AND changed cable positions.

what do you mean by a different spark unit? will i have to buy a replacement part as well as change the position of the green cable?

thanks.

i know from the german forum that both restricted and unrestricted units have the same serial number, how otherwise can you explain that changing the wire gives your bike more or less power? they are also saying that changing the cable can both restrict or-derestrict, nowhere do they suggest changing the unit.
easiest would be to go to a dyno stand and try it.

:pWell, a quick update:p...

I bought the bike in the end from my dealer and once i got it home, i whipped the seat off only to find that the CDI has 4E1A stamped on it, whereas you told me it should have 4E6A for the green wire restriction buisness to work.

Do you think this would make much difference?

I phoned up a honda dealer and they said that both the UK and Geran market CDI's have the same part number.

i had a quick look at the wiring and it seems that it could be the same, however, i cannot be sure yet as i have not had a look at it alongside the document you sent me.

If it is different, then what would you suggest? i don't want to ride the bike illegally and would rather have everything legitimate for if i ever have an accident or get stopped, but i also dont want to have to give in to my dealer and give him £150 for the Fi international kit.

I would be grateful for any suggestions, this is beginning to get confusing!:confused:
