Bye Bye High Temps


Recommended Posts

Ok, one problem I see is getting all the air out of the system, and this requires, burping it.

On the side stand, with the radiator cap off, and cold. Start and run till you see circulation, the thermostat will be open then. Raising the rpm will lower the level some. Don't get too hot, just enough to heat the fluid enough to get the thermostat to open, and the air out, and put the cap on. Add fluid so it is full. If you let off the rpms it can overflow. So just a few. 1200 to 1500 is enough to get the flow going and push the air out of the head.

This is tricky and you must be careful. Don't burn your self.

Could you guesstimate how much of a temp difference this alum. radiator made in hot weather?

Thanks,

The temp still goes up, while at stop lights or slow traffic, on my 2002 but with the extra fan and the larger capacity radiator the temp comes back down rapidly. Since installing the alum rad and extra fan the stock cooling fan hasn't been activated by the temp.

The Ron Davis Rad was approximately the same price as the oem rad, just works better on my bike and gives me peace mind.

Since the only thing on the XX that bothers me is the charging system I don't think I'd want to add the second fan. Mine gets quite warm in busy traffic at high temps but I have only seen that once or twice.

When I picked my bike up from Pat he gave me some info.

His feeling was that some of the electrical issues came fromextra heat buildup combined with added electrical load.

There was a lot going on that morning and I only had about 4-1-2 hours of sleep, but that's what I got from the conversation.

Perhaps the added cooling would also help with the electrical issues.

Yeah - My stator went when idling in traffic, coming back through a really slow customs, at Sault Ste Marie.

A new auxiliary fan, splices, and connector blocks are a definite possibility in my future.

In FLA I've had many problems with high temps on my BB.....But now I've solved my problem. I shifted the radiator 1.5 in forward to get some clearance from the header pipe.(had to do a little welding) Moved the OEM fan to the left side of the radiator. Installed a secondary fan(smaller fan) on the right ride using the bracket from another OEM fan.Made a littte mod the fairing behind the wheel. Installed switch and wire it directly to key switch.....presto. Tonite it's 82 degrees with no breeze and I let the temp climb to 220 and it pulled in down to 208 in 3 min. Have to give an update when I give her a field test...I'll update some pics when I get my camera from the wifey.

I took your advice and also installed a second cooling fan on my 2002 XX and it works fine.

I've never experienced boiling over but the temps would get to 225+ and even though there didn't seem to be any damage to the engine I didn't like looking at the gage reading that high.

Thanks for the info and pic's you sent.

what fan is the 2nd one? I like the size of it, and it looks like a stock fan.

I never had any overheating problems (overheating is defined as the coolant boiling), but it does get warm in traffic when it's over 90... I just spent the $30 to switch to the Evans NGP+, that boils at 375 degrees at 0-psi. The engine doesn't care, a good, modern oil doesn't care, etc...

+1 to that...

I run Evans NPG+... thanks to ... Byrdman

I am thinking of changing to Evans NPG+ - anyone have problems finding a cap that will seal the radiator and make it a closed system? I read that this is something that you must do with the Evans NPG+. Is this what you di

Kazi

Nope. I used the stocker. Have had the stuff in for 2+ years now, no problem. Byrd & Bartonmd use it also, maybe they will chime in.

Makes you feel all special and stuff.

+1 on the stocker cap

, been running npg+ a year

Right, OEM - what vehicle? Honda Accord?

I can never find this dang thread. I need to do this upgrade sometime.

 

auxiliary, radiator, dual-fan, cooling upgrade, fan-fix.

I did the stator myself. I got a feeling of accomplishment from it. 

 

Watching the temp gauge climb stalled in traffic with no sidewalk or apron to get onto was torture. Anthropomorphizing - watching a friend die of heat stroke. We were stuck on "The Soo" (Sault St Marie bridge) for over an hour in sweltering August heat. I made a bad decision and followed my friends across in mostly stationary noon-day rushhour traffic. I should have stopped for lunch as I suggested. ...but I got story to tell.

 

Bike was at about 40,000 miles. It was probably about time by BB years/miles.

I remember years ago making the bad decision to take my 83 V-45 Sabre into Pittsburgh in the heat of summer.  My problem while stuck in traffic wasn't water temp but as the hydraulic clutch got hotter, it came to the point that pulling in the clutch lever wasn't disengaging the clutch.  Just when I thought that I was done, the traffic moved and things were OK.

Well, that the XX doesn’t have a temperature gauge that has a green and red mark so you know what’s “normal,” is part of the problem.  For me, any temp gauge over the halfway mark usually indicates something is wrong.  So, when “normal” is hovering near the H mark, it is unnerving.

If I got stuck and no way to lane split out of there I'd just turn it off.

You're LA-ish? Some places don't lane split. I wasn't through USA customs, still in Canada? The US customs can be difficult too.

 

...time slips by, but I'm pretty sure there are security cams mounted several hundred feet apart. The Soo is long. The ticket may have been cheaper than the repair, but the repair was inevitable in my mind.

 

I did turn it off, pushed it some, restarted it some...  I got what I got.

 

We push started it after customs. The young gal was pretty easy on me. I probably reminded her of her dad.

Yup, about 15-20 miles east of the city of LA.

That might be a bad place to split, sounds like a high likelihood of a citation.  I had no idea you were in border traffic.  First time I rode in AZ I was splitting constantly assuming it was legal, I had no idea CA had that one freedom over AZ.  After knowing it was illegal I did it anyway, but with a little cop caution and extra respect to cagers.

If everything's working properly the bike obviously doesn't need an extra fan, but some people like doing it.

Or move to Montana, I don't think it's ever been warm enough to have the fan come on.
