Thermostat thread size?
Hi, does anyone know the thread size of the thermostat? Going to be plugging the hole, If not then chemical metal it is!
Thanks, Chris |

Re: Thermostat thread size
What bike are you asking about?
Do you mean the bolts that hold the thermostat housing together? Not sure why you would wish to 'plug' them.

Re: Thermostat thread size?
Sorry, meant to stick this in the sv section.
I've got a thermostat housing but no thermostat. I don't really need it as its a race bike, seems to be easier to get The entire housing and stat, but rather than have a spare housing sitting in my garage that will never get used I'd rather just plug it. |

Re: Thermostat thread size?
Just out of interest do you mean the temperature sensor in the thermostat housing?
The Thermostat itself which is in that housing is a device that you would not want to replace with a blank unless you wanted to get very limited use of the radiator. If this is a 99-02 carb fuelled bike removing the temperature sensor will be OK, but for an 03+ you may find the fuelling is affected by not having this input. Jambo

Re: Thermostat thread size?
Hi guys
Firstly I'm talking about my pointy engined curvy Secondly I've been a div,I meant the temp sensor in the housing, I have no thermostat to go in my housing but I'm pretty sure running it without one just means coolant will always flow through the rad. Not really a problem as it's a race bike and will be thoroughly warmed up before its run. Feel free to correct me if you believe me to be wrong... Thanks, Chris |

Re: Thermostat thread size?
I can have a check this evening if that's useful? I have a curvy engine out at the moment so can pop this out and measure the thread & pitch. Hopefully it's the same for all years

Re: Thermostat thread size?
I'm pretty confident it will be the same size for all years,
If you could check the size of yours I'd really appreciate it. Thanks, Chris |

Re: Thermostat thread size?
Seems to be an M10, but surprisingly fine pitch, seemingly narrower than M10x1.0, which is the finest thread measuring gauge I have in the garage.
A quick check with a vernier gauge has 10 threads in 9mm. Jambo Sent from my thingie

Re: Thermostat thread size?
Is it a tapered thread?
Possibly JTPT which I think interchanges with BSPT.
