1999 hornet fan problem

[Troy92]

I've got a 1999 hornet, I have a damaged radiator cap which when idling gets the temperature to rise 2bars below the highest, when should my fan kick in? I daren't let the bike temperature grt higher because the damaged cap is spitting abit of coolant out aswel as steaming. Could someone also tell me the temperatures between each bar, my bike has 5 little bars to chunky bars and then the fat square H C bars. When riding the temperature sits one or two bars above cold.

I'd hate to be riding that when the cap gives out and sprays boiling hot liquid everywhere.

my fan kicks in at half temperature, or just below.

I have owned my hornet for just over a year, in that time it has gone up to just under the red, on more than one occasion, and I think I have heard the fan a total of two times.

[/quote] Sounds Well that's what I've been thinking, I got the bike on Friday and used it for about 30miles to and from work in the morning, so before I went to show it off Saturday afternoon I warm up then left it running off the choke for about 20mins/half hour in the sun and that's when it happened.

my 03 hornet rad fan comes on about 2 thirds up. Had to replace the rad cap on mine as it decided to fail and vomit boiling coolant out on the road, luckily I was nearly home

Getting paddys R1 up to temp took effort.

Had that up to nearly 100 degrees indicated before the fan actually cut in. And that took holding it at 4k stationary for about 10mins to do...suprised me tbh. With that said, if you're leaving it in the sun idling for 20mins with a known faulty rad cap you're clearly spending far too much time counting to potato. Full choke, start it, lid on, choke as low as you can get it whilst still maintaining a reasonable idle & ride off. Just dont redline it through every single gear till it's got a bit of warmth in it...

The other thing to be aware of is where the fans temp switch is located. If it's pissed all the fluid away from it then it'll only go on the air around it so the water will be a higher temp than the switch sees it at if that makes sense? If the waters directly in contact with it then it'll work propperly. Dont ride it with the cap leaking, replace it ASAP & make sure when you fill it back up it's not airlocked anywhere.

30 minutes of choke??

either your doing something wrong or there's something wrong with the bike, I put choke on, wheel out of garage, close garage shut choke off.

Fixed. Thanks for the help
After checking the fuses like said I disconnected the plug and put it to the bike, I got nothing then I noticed the switch on the rad had a slight angle onit, so I tried it with a angle and the fan ran, put it back and tried again and had no luck a couple of times, turns out the clip was originally on upside down so it was sitting on the switch but making no contact. Thanks for the help
