You da man Singhg5! Keep up the good work, I'm proud for you.

Thank you, Singh,
You make me happy to know that I can get through the next 12,000 without any worries.

Congratulations on the 20,000 miles. Does this mean that you will post a video of the de-coke that is due at 20K? I certainly appreciate all your other "how to's" and help.

Buy gas with Techron or pour a little Marvel Mystery Oil in your gas and your shouldn't have to decoke.

Not to digress to far but I've wondered about that 20,000 mile "de-coke" requirement.

For people running a carbureted engine I can understand it because IMO carburetors are pretty poor at regulating fuel/air mixtures.

Computer controlled fuel injection on the other hand seems to be rather efficient and can precisely meter the fuel/air mixture under all conditions.

I also think that even though it is  polluted with alcohol, all of the name brand gasoline's in the US have detergents and cleaners added to lessen carbon buildup and fuel injector plug-ups.

Admittedly they are water cooled but I haven't heard of any modern auto engines that required de-carb'ing at 150,000 miles, let alone 20,000 miles. 

It would be interesting to use a bore-o-scope to examine singhg5's piston and combustion chamber.
I'm betting the carbon buildup isn't any worse now than it was at 3,000 miles.

Paraphrasing Scooter Bob, go out and spank it with a full throttle run.  It's the easiest and funnest de-coke you can do

  Congrates Singh5!  However I think you are overlooking the fact that your vids and advice have alowed alot of us to have trouble free miles as well. Soooo, Technically you can add the 3000 miles I have racked up to your tally! I think it may be a conservative estatment, but I'd say youve contributed to as many trouble free miles as dollars in the current mega millions jackpot.   ::)gotta go get that ticket!

[singhg5]

This journey is a result of cumulative wisdom of individuals, past and present, on this Forum and RE fans in India who shared their knowledge freely over the years. Without this contact through the internet, it would not have been possible to reach this stage.  

A Big Thanks to you ALL !  Keep on Thumping.  

@idk - I do not have any plans to de-coke at this moment. I do 'engine cleaning' with the SeaFoam or Marvel Mystery Oil added to gas tank a couple of times a year.

Keeping sending those vids and thougts...Your a inspiration to us fellow bulleteers..

Me too, always check out Singh5 on youtube before getting oil on the floor. Did have one oil leak at 4k but found that the alternator side case screws have eased just a little , re-tightened and all is well. Only cable to give up was the clutch about 600 miles ago. Frayed at handlebar end , no big deal , replaced with the spare , oiled with gun-oil (stays in place better ) and all is well. Replaced the stock headlight with the 7inch lucas and a modifies H2 bulb which allows me to actually see rather than just being seen

um... didnt win the mega millions

Just think how many bikes you could have bought. Ahh but such is life.

[bob bezin]

it's great to have you on the forum. many more happy miles.

I've recently seen some photos of a UCE chamber after nearly 10k miles.

It's not the intake port showing any issues. It's as clean as a whistle.
But the combustion chamber is covered with thick black soot, and so is the exhaust port. The exhaust tract is plugged-up, and can't get rid of the exhaust very well at all.
Since it can't get out well enough, it backs-up into the cylinder instead of being evacuated, causing excessive passive EGR, and destroying volumetric efficiency by in-cylinder dilution of the charge with exhaust fumes.
These bikes need to get some free-flow in the exhaust.

I'd start with dumping that telephone pole muffler with the cat, and getting something that flows better.
I know how to read a combustion chamber, and I'm saying it can't exhale.

Ace:

You have hit the nail on the head, as you always do.  Could it be a coincidence that in the past few days, I felt that my bike is not breathing well - as if it had 'back pressure'.

I like one thing about the long cat muffler - it is not so loud which makes it easier to ride for long periods. It is more comfortable muffled sound close to traditional RE sound.

Some Forum members have installed EFI silencer or Goldstar or Megaphone silencers, but they are louder than stock cat silencer and some eventually switched back to stock long muffler.  

Do you know of a short free flowing silencer that does not raise decible level - I don't want ear plugs or hearing loss  .
