Title: blueing on exhaust of eBay Ambo bike
Post by: redrider90 on June 02, 2018, 12:38:35 PM
What caused that good awful bluing on the Ambo eBay bike? I do think I have ever seen a muffler blue like that.

Wow! That is not good. Maybe the ignition advance is stuck, that and some ill carbs will wreck some chrome pipes.

Extended idling in hot weather conditions causing over heating will blue pipes. Not good for the pipes or the motor.

The one pic of the left side looks okay. The pattern is odd.  Could that be deliberate? Seems that it's a new fashion trend to make it look like your bike is out of tune.

My guess is incompletely burned mixture coming out the exhaust and continuing to burn.  That could happen from an overly rich mixture and/or very retarded timing.

the big bore needs to be checked out, if they used a set for an 850 the piston deck height will be wrong and could be part of the tuning problem

the engine number has a VG prefix, wouldn't that make it a Convert, G5 or SP motor?

If that was a modern V7 I would say that the plug/cap/wire was shorting and not firing the fuel, sending raw fuel down the pipe to be burned in the cat. I don't know when they started putting cats on motorcycles.

I did now get an answer thru ebay,
"It was running lean is all. It's been corrected. No damage. It's not a conversion kit. It's an original 1000cc motor from a newer bike. Thanks!"

"No damage", except for the blued chrome exhaust pipes! And it is listed as a Bobber!  Nowadays, sellers call anything that is missing parts or bastardized, a bobber or cafe racer kitted.

 :thumb: Yep and they claim 1971 Moto Guzzi Ambassador - fully restored " and "new chrome". Really those pipes are "new blue chrome". Someone made a huge mistake setting up the fuel/timing on that bike to get that much bluing.

Can you claim a bike is fully restored after putting 20K miles on it after the so called restoration? At what point is it a used bike again. After all full restored implies a like new bike and this "ain't" no like new bike. It might be light blue (chrome) but not like new.  :grin:

I thought the pic "artfully" hid the left side. It might be an ok bike but not at that price

Bobber implies bobbed fenders which this bike does not have.  They just pick a word that is popular at the moment to get a hit during searches.
