    Hey Guys,

    I was out of town for a month and had covered my bike with a good quality bike cover (Nelson Rigg) and the bike was standing under a roof. On my return, when i removed the cover i noticed that my exhaust had changed color at one place. How does that happen?? .. i don't think anyone touched my bike. I know it had rained a few days while i was away but the cover and roof should have prevented real damage.

    WHat can i do about it... other than sending it for chroming. Can i apply some cleaning or polishing cream / spray etc.

    Thanks

    Can you take a pic and post it? Is it turning blue or yellow? Blue Job works great for removing those problems.

    Hey sorry for the late response .. was out of town.

    The pipes are stock on a 08 model. I recently drilled my pipes and a local mechanic on the phone (with out looking at them) told me that it could be because of that.. excess heat.

    I know many have drilled their pipes on this forum.. so has it happened with anyone else...or have i drilled them wrong.

    Now that this has happened what can i do to fix it... and will it keep happening again.

    Pics are attached...

    Thanks Guys

    Also guy those scratches you see on the left of the blue on the exhaust are the efforts of removing a burned cover that got stuck on the exhaust cause my friend put the cover on it while it was hot... so a new question....

    how do i get rid of those scratches from the chrome

    Thanks

    Hey! Where is "elsewhere". I want the end of the story! Why did his exhaust do that?

    That is where the converter is. Are you sure it didnt stop up causing excessive heat. I ran mine drilled for two weeks and then removed the cat completely! I had 0 discoloration. I put a set of 3" HardKromes because even with no cat it just wasnt loud enough!

    Ah yes... "elsewhere".
    With the discoloration looking that bad, I might opt to rough some areas of the exhaust with fine sandpaper and spray with black heat resistant paint. The design is up to you.

    As for getting melted stuff off of pipes, I have used "Goof-Off" with excellent results. Sometimes some gentle polishing with 0000 steel wool will help with scratch marks from too aggressive cleaning.

    "Blue Away" has always worked for me to make the discoloration fade away where it's not noticeable.

    HERE is a Cruiser Customizing video discussing the removal of bluing and scuff marks/melted rubber/plastic bags from the exhaust. This, along with a few other things, are what I mentioned "elsewhere," with "elsewhere" being on another forum where the same question was asked. : )

    Enjoy your weekend.

    added: #0000 steel wool and a chrome polish can also work on occasions, plus it also can be very effective at times at removing surface rust, pits and scratches.

    Went for a ride this last sunday and after only riding for 20 odd miles my buddies pointed out that my pipes where red from the inside. I stopped and looked in as it sure looked like "coal out of the fire" red. I rode for a while and even felt the bike sluggish and running extremely lean... in spite of having Jacks Mod installed.

    Anyways when i reached home, i requested a mechanic to have a look at the pipes and he told me that i should replace them cause i had over dripped them and that the Cat was visible and that there was pressure kick back (blow up sounds) from the exhaust which would eventually affect my engine.

    Now i am sitting in India and we don't get this bike or any parts here (Bike was imported from Singapore). I just don't understand.. i did everything all forum said about drilling the pipe.. then how is it possible that i have over drilled them. Now have to figure out how to get new pipes for my bike.. stock or aftermarket. Getting them shipped to india is like paying double for the pipes.

    Attaching a pic of the pipes looking inwards. This is a few min after i was done riding.. so the redness has reduced

    Damn mate i havent ever seen an exhust do that..Not much i can suggest...I presume the bit you drilled came out again and you havent drilled into the cat?? Just seems odd that the heat is around the drill area would think if engine problem whole exhust would be glowing...cause its bad i wouldnt be riding it till its sorted and i would split the muffler at the cat joint and see whats what...If you used a dremmel it shouldnt be too difficult to pull it apart...you never know you might be able to see why its doing it..Fix it and paint muffler black and save a considerable amount of dollars...Sorry best i can come up with...

    Yep sounds like your running super lean. If you pull off your pipe and the cat looks normal on both ends and you can see through it well and its not melted its probally ok. You dont have any mods listed to dont know what ya got and why your running so lean. Could be a problem with the bike or maybe something happened to your O2 mod im not familiar with them. You may want to think about adding fuel management, checking your fuel filter(pluged) or maybe try just unhooking your o2 to test and see if it cools down the exhaust. Just some ideas.

    Man u all have to read this.. so i decided to change the pipes with a friends stock pipes as he had moved on to aftermarket ones. I figured no point trying to remove the blueness, the scratches and of course the redness of the cat which may have been caused by my drilling.

    Now my friend had also drilled his pipes but he got it done from a mechanic and had removed everything - cat, baffles etc. It was basically just a hollow can with some insulation / glass wool... but it sounded awesome.. i mean the "thump" was heavy and just awesome.

    So i decided to take my bike out for a ride today and barely after 2 miles i stop at the stop light and notice everyone if staring at me.. it normally happens cause people in India haven't seen these big bikes.. and of course my good looks..

    But i also noticed smoke and when i turn around me check out the pipes... the pipe tips were one fire.. on actual fire.. not red hot or spiting sparks.. but flames. Even when i switched off the engine.. the pipe tips had flames on them.. as if i sprayed oil on it and put a match next to it.. when i looked inside the pipes i could see the glass wool or the insolation material on flames... a street vendor noticed and quickly brought me a bucket of water which i used to extinguish the fire ... dragged the bike to a friends place close by and called the mechanic.

    After inspecting the bike he told me one of the spark plugs was not working and needed replacement and all this fire was due to the unburned fuel from that cylinder. He also said that maybe the bike was sluggish cause only one cylinder was working and thats what may have caused the excess heat leading to blue pipes. fuel could be burning in the pipes before that cat and causing excess heat and now that i have installed pipes which has nothing in it (Cat / baffles).. that heat with totally unburned fuel caused the fire..

    So now i have changed the spark plug with something similar that i could find in India and removed the O2 mod (for now.. at least). What a difference it has made in my bike and as if all the sluggishness on my bike has gone away.. now i am thinking maybe my plug was screwed for a very long time but i did not know what was wrong..(i had posted a question earlier with the title - Bike Jerking - Need Help).. i assumed from the first day that this is the way the bike runs and i am just feeling it cause i use to ride a M109R (1800cc) before this..

    Now i am looking for the right plugs on the net for the 1300. My mechanic recommended NGK iridium spark plugs... but there are many iridium plugs out there... please guide as to which plugs i should get and where.. some shop / website / place which will ship to India.

    Once again .. the look on my face when i saw fire coming out of the pipes.. .. man i bet this is gotta be a first. Anyways just thought i should share this.. will keep you all posted... but can u imagine all this happening to me when i am in India and i have no Yamaha back up for this (we have Yamaha .. but not for big bikes..) .. and no access to parts.

    Anyways help with the plug info guys.. please.

    Thanks
