Coated Pipes are Scalding Hot!

[Ridgeback Boy]

Anyone else have pipes that have been powder coated and the temp is much hotter where they are between the cylinders?

I am thinking the jetting is lean thus running real hot, I had to have the jets changed to pass emission's here in Phoenix and the shop said after it passed they put the orginal jets back in but I dont think so.

Any other thoughts, the heat is ridiculous!

If you think it's that hot, check your plugs, they would have to be white. How hot is hot? Do you have a oil temp gauge?

 

[Ridgeback Boy]

No oil gauge, just pulled the plugs...they look great. Toasty gray/brown.

Would bad or old gas have anything to do with it?

No. Not heat. Poor running yes

 

[Ridgeback Boy]

Running good, I dont get it. Maybe the pipes are not really ceramic coated but told if they were not the paint would be bad by now.

Are your pipes coated inside and out or just outside? The only way you get real heat reduction from ceramic coating is if they are coated inside and out. And even then the reality is there still going to get hot especially of you don't have heat shields.

 

[Ridgeback Boy]

Coated inside and out, these pipes were new and chrome and never ran this hot.
I was thinking it was the cylinders but they are not generating anywhere close to the same heat on the primary side as on the exhaust side of the bike.

 

[KaptinAmerika]

Huh

 

[BBChopper]

Huh

X2

That the motor / cylinders are not extremely hot, it is only the exhaust.
Not sure if that was important to mention now that I think about it, exhaust will always be much hotter!

 

[BBChopper]

I don't know but sounds normal for an Air Cooled Bike.

I am confused about the between the cylinders part? Where what is between the cylinders?

Go to the nearest auto parts and barrow a heat gun and lets us know what you are operating at.

You may be just running way lean on the air/fuel mixture screw. Check and see how many turns you have it out

 

[Ridgeback Boy]

Thanks Ray, I turned it out a 1/2 turn yesterday and will see if that helps.

BBChopper, what I was trying to say is where the pipes start to join below the carb is where the most intense heat is, not sure why I included that.

I will do the heatgun temp and let you all know, thanks for all the responses.

You might also check for an exhaust leak.

Unless jet hot did the ceramicoat I would doubt the inside is coated very well.

My first set somebody else did it and they told me later the just spray some in there and hope for the best.

 

[Ridgeback Boy]

Thanks RCAdd1ct, thinking the same on the coating.

 

[KaptinAmerika]

I don't know of any company that will ceramic coat the inside of any pipe if the pipe is not brand new and unused. They can't get the ceramic to adhere well enough and their fear is that the ceramic coat will break loose near the exhaust and inadvertently get sucked into the motor.

I had a set of the hooker four into ones that were ceramic coated and those MFer's were HOT! So hot infact the warden made me get rid of them. Looked cool as hell but out the door they went.

Jet hot did a set of used pipes inside and out.

Their warranty is only for the outside, though.

 

[Ridgeback Boy]

Ok, temps were:

Front 470-505
Rear 500-560

Both around 8-10 inches off the cylinders under idle.

I did go out a half turn on the fuel mixture and I "think" I can feel a small difference.
