Bike is getting unusually hot... reassurance needed!

My bike (Hornet 600 04 model) has been getting rather hot when out on rides recently, I've noticed it ever since i changed the oil, i put 10w30 in it, and now the bike seems to get rather hot, its ok if im in open roads and there is enough air but when im crusing along or in traffic, its getting very close to red. Is this normal, is 10w30 oil ok for my bike?
Cheers.

Oil should be 10w40

Hornets do run hot, mine is near to the fan cut in temp even when moving at 30ish in this heat

I read that 10w30 is recommended for hondas?
Should i change it to 10w40? or will it be ok with 10w30?

30 is thinner oil than 40 so heats up quicker, better for winter... but if your finding it running too hot you should try the 40

I only changed it a couple of weeks ago, thats £40 squid down the drain. . .
So What oil do people recommend or use ? 10w40 what? fully synthetic or semi? and by who - castrol, motul, rock oil, etc.
Cheers.

Get a haynes or read one of those online haynes manuals to see the oil type, if its wrong then change it I wouldnt bother with fully synth but this is a very long argument.

I use semi synth but check it is suitable for wet clutches. Brand dosnt matter as long as it specifies for motorcycles.

I have a haynes manual, and i have also read the bikes manual it says either 10w40 or 10w30 dependant on usual running temperature.
Its also fully synthetic, is that ok to run on a hornet? I also found when checking the level the other day that its above the top line of the dipstick, is this ok?

Cheers guys, I appreciate the replies.

I think at the next oil change i will use castrol gps 10w40 semi synthetic.

I am running GTX Magnatec at the mo. Seems okay.

A lot of people recommend Halfords own make oil and just replace more regularly

Why is it a big thing if it is above the top line? what will this do? i emptied it once as it was too high, ended up emptying too much, then ended up putting too much back in and have not emptied any but i may if its going to cause problems to the bike.

You can get oil that isn't Halford's cheapest?! The deal was sweetened when they started giving me free screwdrivers with it.

I've heard fully synth isn't great for hornets, I did some online research when changing the oil on a friends hornet.

...well thats not so reassuring to hear fully synth isnt good for hornets. . . . I think i will change to castrol gps semi synthetic 10w-40 at the next oil change.
