Classic styling and Kawaski colour schemes. Just like the bigger GPX bikes (only smaller so if you're tall or big you'll look like you're riding a Shetland pony). Not very heavy so watch those cross-breezes on the freeway (i.e. wind shears). GPX250, ZZR250, GPZ250R all use variants of a water cooled DOHC 16 valve parallel twin. Tough but watch out for thrashed engines. Cinder-switch is occasionally burnt out so check it when buying. Bookmark/Search this post with: | ||

HP
Hello,
ich bought a GPX 250 last month, but it hast just 34hp. My question is, how can I get the missing 6 hp?? My bike is from 1994.
Thanks for help ;)
Cinder-switch?
Can someone pleaes tell me what this "cinder switch" is?
I've found people asking each other what it is based on the bike description on this site and no one seems to know.

The GPX250 has a number of switches such as the kill switch (to manually kill the engine in case of accident) and the clutch cutoff switch which will kill the engine if you release the clutch while in gear with the kickstand down (doh!). But it's neither of those (if either of them isn't working then it's been known that you'll find the bike stops and starts intermittently).
The cinder switch is actually a thermostatic switch (a switching circuit, not an actual switch although some people might have wired one in) that senses engine temperature and turns on the radiator cooling fan. This will work even with the bike engine off. In fact, you want it that way because it stops your bike from overheating if you stop the engine after a long ride with a big heat build up in the engine. It's been some years since I've owned a GPX250, but from memory it's pretty obvious - look for the thermostat plug and wires coming from the radiator fan and see where they meet up. Someone who actually owns one currently, or has a workshop manual might be able to provide a photo and more detail.
The term is intended to convey what will happen if it doesn't work (ie your bike catches fire and burns to a cinder) and I've heard tell the term originated from something to do with trains or other switches intended for the same purpose.
The term has been around for a while, but strangely isn't too common on the Internet that I've found. In fact, if you find references to cinder-switch they almost certainly stemmed from this site, with the original usage going back to the 1990's from the Usenet group aus.motorcycles (perhaps Australian slang?).
I'm certain that the bigger models (eg GPX750) have this as well, and it's probably not uncommon in general. A good idea, really.
If you're buying a second-hand bike it will not be immediately apparent if this switch is working or not (at least not until you've shelled out the bucks and ridden away) so do get the engine nice and warm, turn it off, and check that the cooling fan kicks in.
By getting the bike warm, you
By getting the bike warm, you really need to get it WARM. Might be hard on a reasonably mild day. Mine kicks in when the temperature gauge hits about 3/4
