Link To Cromet Heat Fix?

[rcsnclh]

All this talk of heat has me a little worried coming from the cool :agent: (but much slower and admittedly dated) ST1100. I've seen reference to "the Cromet fix" but haven't been able to find a link.

Can someone point me to it?

Thanks,

:clap:

Actually Cromeit Left Side Heat Fix, of course if we spell it three different ways someone is more likely to find it using the search function later.

Want to ask people who have done this about the removing or modifying the black plastic panel which Cromeit suggests to leave out.

To me this panel appears to do a couple similar things. One, it directs air into the radiator and does not allow much air to go around the outsides of the rad. Second, it also keeps hot air from the back side of the radiator for spilling forward (while stopped, idling), this is know as recirculation and is not particularly good for idle temps.

I'm guessing the percieved value of removing/trimming this piece is that it actually allows a blast of non-heated air down the left side to mix with the heated air from behind the radiator and around the exahaust headers. This is seemingly a good thing for the rider, but I would have to think its not the best thing for the bike because you are forcing less air through the radiator and allowing recirc at idle.

Thoughts? Anyone actually but a digital water temperature gauge on their bike?

I just did the Cromeit thingy and it works great, but I would prefer to replace the part he says to leave out. If anyone has any input as to what would happen if I put it back in, please advise.

Gryphon68 hit on the subject, but has anyone really tried both ways?

I cut it where Cromet said and reinstalled it. Ever since doing the mods my ride runs at three bars in any condition other than highway speeds when the temp is over 75 degrees. Even then if I'm following a vehicle at it's over 85 degrees it'll run three bars.

I'm hoping this is due to the modified part. I'm going to order a new one (~$30) to see if it changes the running temperature.

I didn't modify mine. I just left it out. It has been 95-102 degrees since I did the fix. Mine runs at 3 bars when I'm messing around country roads at 30-40 mph. Soon after I get on a straight run and exceed 50 mph it drops to two bars and holds stable even in 102 degrees. I didn't really pay attention before the mod, but I would think that is normal.

Here is my educated guess, if you leave the full panel in you will actually cool the bike better (coolant temps), particularly if you get trapped in stop and go, heavy city traffic when the ambient temps are 90+.

Comparing the heat dumped on your left shin, leaving the panel out will probably result is lower temps felt by the rider.

The black plastic deflector and the prescribed block off shield (aluminum) do not overlap. You are not "making up" for blocking the space between engine and frame by leaving it out. The plastic shield does not effect hot air flow rear of the radiator. Installing the metal plate only forces hot air from behind the radiator to exit the side vents in the fairing rather than being pushed back between the the engine and frame, resulting in a superheated blast.
