Electrical problem, Igintion problem or Engine issue ??? Need Help

About the speed, I put that beast at 270-275 km several times.

I think it was just a language issue or typo.  It sounds like you are saying you were going extremely fast for several periods during an hour.  But the posting's wording said you kept up such speeds for an hour... continuously (which seems quite unbelievable).  No big whoop.

Uhmmmm, may be .... You know
My english has improving since i bought the bike
but .....

Very high speeds also bring on very high loads on the entire drivetrain. Sustained high speeds exaserbate any potential problem.  I am not a doom- crier and I absolutley these engines in the C-14 are extremely robust and rugged but.... if it happened suddenly such that you felt it, after or while maintaining very high speeds, I would do a compression check on the engine, at least the left two cylinders (to actually test the cylinder that is 'bad' and also to have another cylinder to compare the pressure readings with).

I suggest this AFTER checking the fuel injector though, that is still a likely culprit IMO. But if the injector is not faulty, given this new information, I would begin to suspect engine internals (Easy Boys), starting with the top of the piston. Sorry to be the bearer of possibly bad news. :-(

The bike has 70000 kms.
I felt the problem suddendly, nothing happened before
About the spped, I put that beast at 270-275 km several times.

Over 150 - 156 mph for at least one hour?  Seems unrealistic as MCN reported the top speed to be 153 mph.

That spec would be for the inferior speed limited Gen 2 C-14s.  Gen 1 C-14s are not speed limited to 153 and I do believe that JhV has a Gen 1 bike.

Nope they are just aerodynamically limited to about the same thing

Oh no he din't!

Any progress or word on the bike and that cylinder?

Not Yet.
Because my job, I only have the saturday for work on it.
But, sincerely, i'm a little pesimist about that. 

[B.D.F.]

I can understand that. Still, if there was no loud bang or anything similar, I am still holding out for an fuel injector failure. It is more common than broken pistons for example so the odds are with you. And other than being a bit of a pain to get to (other than no. 1), they are easy to change and really quite reasonable in price- something like$50.

Still thinking good thoughts in your direction.

I think it could be as simple as a bad spark plug. Once my crazy 2nd wife drove her Honda CRX  at 95 mph for about 90 miles. The next day it would only run on 3 cylinders. I replaced the pugs and all was well. Wishing you the same result.

[B.D.F.]

Yeah but he said that he changed the spark plug and swapped the coils between cylinders #1 and 2 and the problem remains.

I did
Detach the power commander too

sorry, missed that

You never said how many miles or Kms you have on the bike.
Did this problem start out of the blue and all of a sudden or did it start to run badly and get worse and worse?

Is the bike totally stock except for the Power Commander?

Mine's bigger than yours and will do 280 kph...

[B.D.F.]

Yeah and it is too bad that is no longer an option to fix this as that would be THE cheap / easy option. The fuel injector is not too bad either but after that it may get ugly.... Still holding out for the injector myself.

Brian

sorry, missed that

jh, in your first post you said the bike starts but will not run at idle. What about at higher rpms? Have you taken the bike for a test ride since the problem arose? Please consider a clogged fuel filter as a possible cause as it would inhibit fuel delivery.

After the failure, I don't want rev up the bike more than 4 o 5K rpms.
At 120-130 KpH (60-70 MPH) the bike feel steady, not as usual.
The sound is Horrible, faint, without power.
I was thinking about the fuel filter, specially now, because de fuel here has been coming dirty.
I will check that. Thanks
