PLASTIC ON HEADER PIPE

[Spuddy]

Moving Lola (still warm) around in the garage, I sorta dropped her on one of those plastic detergent buckets. While I got most of the plastic off the warm header pipe, a black splotch remains.  Although I can live with it, I wonder if there are any other cleaning I haven't thought of.

The bike is ruined. Post a picture of Lola and we'll figure out someway to get it out to me so you don't have to see it any more.

Although if you ran the bike warm and wiped at it with first wood, then stainless steel scrubber, you'd probably get most of it.

Run it to hot, and you'll bake it on, so caution is advised. This is a wholly uneducated opinion, coming from a guy who hopes you'll give him the bike.

Easy Off oven cleaner but be careful with the overspray. Apply on cold metal before bedtime and rinse off the next morning. Follow with Nevrdull. This might also be a time for the battery charger/sulphuric acid treatment.

I have found the best solution is to ride it.
A. You can't see it from on the seat. :evil"
B. With time the heat will turn it to carbon and it will brush off easily.

Most of the time chrome cleaner works real well. Used it several times.

Warm it up then scrape it with the edge of a penny. The penny will not scratch steel, but does a nice job of removing baked on plastic.

Easy Off, then a PLASTIC scraper, then wadded up aluminum foil.
Rinse and repeat.

Hey, I still think we should at least get a picture, even if you guys are discouraging him from giving up on it and giving it to me.

The simple way to remove it, without scratching the pipe or actually having to work, is to soak a rag with MEK (methyl ethyl keytone) and lay it on the spot.  After a moment, it should wipe right off.  Do it outside and wear gloves to avoid getting that solvent on your skin.

Don't know if this will work on the plastic,but I've removed burnt on bootsole from my exhaust a few times by getting the pipe good and hot, then giving it a shot of EasyOff. Usually dissolves and run right off. But be careful and DO NOT breathe the cloud of fumes it creates.

I once owned a R100RT, and while riding through town a plastic grocery bag blew onto my header pipe.  I didn't know what to remove it with, so I left it alone.  It crusted up pretty solid.  I had it in for maintenance (local dealer at that time was Fort Worth BMW owned by Perry Bushong), and Perry suggested using crome cleaner and a copper scouring pad (for pots & pans).  It worked fine, as the copper is less hard than the stainless steel pipe.  I felt kind of stupid that I hadn't thought of that myself, since I'm an aircraft structural analysis engineer.

Burnt some plastic on to the Breva's exhaust. Couldn't find my metal cleaner but as we had a ride or two lined up, well, I rode.

Burnt plastic has completely gone. About 5-600 miles of riding at an "exuberant" pace should do the trick. Trust me, I are a doctor.

Easy off.

Ride it til it's hot, shut it down, spray with Easy-off oven cleaner (cover everything to protect from overspray!!!)

[pressureangle]

Try this. If not, try 3M adhesive remover. Don't use any scouring pads, or cleansers. You have to remove it chemically or it will ruin the finish.

as mentioned above - Get pipes hot, easy off oven cleaner and if SS piples, use a stainless steel scrub pad.  I also sprayed easy off on and left overnight.  Came right off.

O.k. so I had the exact same problem.  Heard the rain coming so I rushed out to throw the cover on.  Unfortunately the Griso pipes were still hot.

It looked like this:





So I went to Walmart and got these:





And 5 min later it looked like this:





Pretty straight forward.  Heat the pipe, wipe a little of that iron cleaner with a cotton (not micro) towel, and a little bit of scrub with the copper wool.  It's a little duller in the second picture as I followed up with some all metal.
