Hey guys, does anyone out there know a lot about the aussie issue RS 125's? I have a beautiful 2004 (apart from a couple of scratches I caused on a fairing from a garage drop - waaaaaaaaaa! - bring that up in another post) and I'm struggling to find out some little things about it such as whether it is restricted or not. Some say all the aussie models are unrestricted?!? I've read around and I do indeed have the powervalve and solenoid installed, and it does indeed get a bit of a kick around 8krpm. However I'm unsure about the spark plug arrangement and also the jetting situation. It has the standard 28mm Dellorto Carby, which I thought wasn't enough for an unrestricted 125? So I'm almost guessing that perhaps the power valve isn't turned on or plugged in (though the 8-9k kick would suggest otherwise?). I'm going to take it apart today, and hopefully manage to do the CDI derestriction mod at the same time, but am worried about spark/jetting issues. - do I need to rejet/change spark after that - or generally only if I change the exhaust? When I bought the bike it had some dodgy denso plug in it which is the same as a BR10 apparently, and I noticed it was rather black and oily and a little carbony - suggesting a rich mixture? So I bought some BR8ES NGK plugs and I think they are running a lot better (supposed to have 8 at restricted power, and 10 at unrestricted - from the manual) The BR8es gets a tan colour electrode which I think is correct. Now I'm curious as to what this means for my bike being restricted or not. If I do the CDI mod, do I then need a 10 spark? I've ordered some iridium 10's but after I did that I read on a UK forum that the 10s should only be used in really hot climate weather... which I suppose isnt for about another month or so in Melbourne, or you fang it like a GP racer - which I don't. Otherwise you will be fouling them really fast. The same forum was suggesting that a 9 plug was a good compromise between both hot and cold plugs. I'm not confident enough (or crazy?) to attempt to do a plug chop considering I've only been riding for just under 2 months so any advice would be greatly heeded. I suppose I can't go wrong if I'm willing to sacrifice a 10 to see what it runs like? Also - this may be a stupid question, but do the stock cans come with a CAT or is that purely a US thing? One last question - does anyone know what temp the bike can hit before I start to get worried? I think the hottest I have seen it is around 78 degrees... And I'm a little worried in the coming months at what it might get to... especially in traffic. Does the spark plug effect this at all?
