GSXR 100 2011 won't open up at full throttle

My husband did a tune up on GSXR 1000 2011, but when he gives it full throttle it doesn't want to go - at 190 degrees, it refuses to take the fuel, and bows down.

Super vague description.

That being said, the first rule of troubleshooting is what is different now than before? He needs to check his work.

Explain the symptoms, more.

I videotaped him explaining it, but I'm not allowed to include links.

He changed the fuel pressure regulator and it's fixed.

So it relapsed. I placed a new fuel pump, new pressure regulator, new spark plugs, new strainer, and had the 8 injectors cleaned. I would run the bike for 15 or 20 minutes, and then if I go to accelerate or overtake it bows, it won't take the fuel. What should I look for? Could it be the 4 coils?

Re: GSXR 100 2011 won't open up at full throttle

This once happened to me (after I installed a fuel module), and it was because I put the fuel line in back to front (or the wrong way around).

So get your husband to check the fuel line, perhaps he installed it wrong, a lot of people do it, and it causes the exact problem your describing.

If that's not it, perhaps you could make a video - thanks, and good luck!

Re: GSXR 100 2011 won't open up at full throttle

Out of curiosity - who and how cleaned the 8 injectors?! The only time I tried it (on a bike with high mileage) it messed them up, it can be really tricky and cause problems if you upset any residue in them...
...and as MacBayne said: what did the husband do?! Could he revert it by any chance?...

It won't help at all but it is just as irrelevant as any advice at this stage without details of what's been done: I had the bike losing power and not working out of the blue where it turned out the pin in ECU broke responsible for powering fuel injectors due to water in the connector - but it is not the case there, your husband did not break anything, did he?

It looks like a fuelling problem, a bit obvious, ain't it?
Saying that, it could be anything, I had problems getting power above some 8k once when secondary throttles actuator failed due to the sensor mulfunction but this way anyone can tell You their story and You will change half of the bike getting nowhere.

Tell your husband to de-tune it maybe?! lol I'm not too helpful, am I?

Currently on GSXR-1000K4
used to have GSX-R750Y and GSX-R750K6(among other bikes).

Re: GSXR 100 2011 won't open up at full throttle

Juny wants to know if you think the problem is related to electricity or coils?

He cleaned the injectors, placed new spark plugs, new fuel pump, new pressure regulator and a new strainer. He thinks the fuel is ok, but he's wondering if it could be related to current, and what would be the remedy if it's electrical problem. When he opens throttle it's still diving.

Check all three components of the charging system. If that all checks out, test all the coils.

Ask Juny to check he didn't put the fuel line in back to front - lots of people do it and it causes these symptoms. It's a simple check - takes about 5 minutes

He put it back to front and the bike hardly wanted to start, so he returned it. This is a 2011 bike, it only goes one way. He said you can't reverse the line otherwise it will kink and bend; it's set for one position, he said.
