Scooterotica

Hi all setting up a Mugello 186 with a 28 dellorto phbh carb , the temp gauge can run at 170-190 on 18 mile journey sitting between 5,500 and 6,000 revs.
Plug looks a lovely brown colour when I do the plug chop at around 6,000 revs , the owner is concerned it is running hot. Never used a temp gauge before so what guidlines should he be running at .what is a safe temp ?

Hot, a lot depends on where the sensor is

Just fitted to a fin on the head , far side where the exit is jon

if its farenheit then its ok, if not its hot!!!

Better read up on them then ? Dont have a clue

The numbers are academic, if it's set up and running fine with good plug colour then the number is correct

Agree with ^.

Treat the temp' shown, when running well, as a reference point. If it goes above that then you may have a problem....or you've set your reference point too low..

i have a sip speedo my temperture range is 190 to 280 anything over start to worry temp in f degrees for mine hope this helps m8

I had same set up on my gp muggy 186 same carb with breath easy and taffy rep pipe and yes sat between same readings as u have stated . Would go a little higher if I opened it up more

Cheers guys just what I wanted to here . I know the plug is right after setting it up this morning, so he can ride it now. Myself I think the exhaust temp gauges are better for scooters but so long as we have a start point and go from there.
Thanks everyone .
