i love my 03 1800vtx c but i hate the heat it seems that even riding on 40 degrees its allways hot more so than any other bike i owned, any sugestions on how to install a bigger fan or just deal with it .

You could try adding Water Wetter.

What kind of pipes are you running? Any aftermarket intake/computer? There may actually be a lean problem... or perhaps a cooling system problem.

My 1800C gets warm... but it seems a 'normal' warm.

Try riding a Harley. Take about heat. Whew

 

[Mortikus]

Lol, tdub, demo, it's not so much about whether it's comfortable when it's running properly... if the engine is not running properly the heat isn't about discomfort, it can be about damage to the engine... much more serious.

And welcome to the Cafe demolyrozer ... lol, or not

-Does the fan kick on and off?

-Does the dash light for temp come on?

-What is the scenario when you feel it is running hot....while sitting at a red light in town, while on the highway, etc etc?

- Have you ridden large CC bikes before? Not that I think that is really the issue -- but 1800 CCs of engine will have an overall higher amount of heat coming off the whole system as opposed to a 1300 or 800 etc.

- What do your spark plugs look like? Burning normal or white??

A properly tuned liquid cooled engine with a properly functioning cooling system will run the same temperature, regardless of displacement...Doesn't matter if it's a VLX 600 or a VTX 1800...Thermostat in the cooling system controls the coolant temperature...But a lean running engine will run hotter due to the A/F ratio being off...

But all this goes right out the window with an air cooled bike...

I'll feel the heat at a stop light when the fan kicks in. I also had my Temp light go on when I had an air bubble in the system after a coolant change. When was the last time your coolant was changed? Also, without :stirpot:, engines will run a little cooler with synthetic oil.

If the heat is coming only from the right side , might be aftermarket pipes...

thanks to all replys , i will have a motorcycle mech in town check it out because my light has not come on at all the fan sometimes runs and i did swicth over to synthetic without moly , some of you mentioned the pipes , i have the bubs , will be analyzing it all this weekend thanks againg to all replys,

Please let us know what comes of it. Your learning experience could be helpful to the next guy

The temp should never reach more than around 185, and thats just not that hot.. Ive got aftermarket pipes as well, and I've never experienced any type of Heat Discomfort. I mean, of course its going to be a little warm.. but it shouldnt be hot enough to cause discomfort...

I can take my hand and put it on the jug's fins at operating temperature. If you can't do this, something is up.

Funny you mention that because while my VTX doesn't have a temp indicator, my CBR's dash has a digital temp guage. When it comes up from cold start it's not warmed up and stable until 172F, if I keep moving and even flying around it'll max at about 175~177.

Now if I sit in traffic it'll start creeping up, all the way to 220F before the bike goes into 'oh chit' mode... must be a thermostat because it'll drop quick, and the fan kicks on if need be... but it won't let it go any higher.

I imagine our VTX's are similar.
