RUNNING HOTTER THAN USUAL

[carlos1982]

at the weekend i had manual ccts fitted and then gave her a k&n filter and an oil change, i took her out for a blast yesturday and she appears to be running hotter than usual! any ideas? or have i just answered my own question with the k&n?

i don't think shes been jetted!

many thanks

Try adjusting the cct's, back them out until you just hear a slight tapping noise, then in until the noise stops.

K+N won't make it run hot.

oh i dunno... it will run hotter if its running lean...

[tony.mon]

Yep, but usually not enough to notice on the temp gauge, just the plug colour. And not in this weather, either.
(Hmmm, unless it's a later one with digi readout, a few degrees might show up then...) Is it?

[benny hedges]

yeh thing is the temp gauge only shows coolant temp.... as in it doesnt show oil temp and stuff...if its running lean you can smell its hotter...
like the things that arent cooled get hotter, noticeably the headers, melting the belly lol!

[tony.mon]

You might be right, Benny.
- if the original air filter was clogged up the difference might be noticeable.
Try putting the old filter back in and see if temp drops again?

If so, refit the K+N and take it to be jetted and set up properly. Not normally noticeable, though- fitted lots of these, and no-one's commented before....

By the way, what cans are on it, and any other engine work?

May be running a bit hotter, but is it too hot? what temp?

no other engine work done to my knowledge, viper cans. only done a couple of hundred miles on the old airfilter, and temp is probably me
being over cautious. the fan cuts in and cools it back down, just coming on more than usual in traffic ect

[tony.mon]

You'll have a bit more power; that produces a bit more heat.

It's not a sensitive engine, so although it's probably running a bit lean it won't burn holes in the pistons, as it's quite a low compression engine.

Probably a good die to get the jets changed, but not in my opinion essential or needed before you can ride it.

since ive had mine it runs quite cool never been hot enough for the fans to kick in, on the older type gauge when should the fan kick in
