hi! im new here

ive searched the forums and came to a conclusion that my fuel is too rich? this happen after a few track days and its starting to get worst. I sent my bike to the workshop and well... got worst too lol

it seems to be struggling to climb up the rev range and now it barely climbs over 4k rpm on 5th gear.
1st 2nd gear seems fine but HUGE loss in power

any ideas? i would like to adjust the pilot screws but cant seem to find it! must i take the carbs out to locate it?

thanks :D

Help us out:
What exhaust,
What air filter / air box mods,
What jetting?

Also, I hate to be the bearer of bad news, but I think you are wrong. Fuelling is right or wrong and other than if your exhaust baffles collapse or air filter breaks up, it won't go off or get worse. I think you have a more major problem inside the engine. Maybe a burnt valve.

I would suggest you stop running the engine now before you kill it off completely, and get a compression test done.

Is the bike running on all cylinders?
Is the vacume tube old?

its the stock exhaust/airfilter and no mods i guess...

i just got it 2nd hand of a shop.

i know nothing much bout the settings haha.. ill prob bring it to another shop to check it out

thanks :D

If you only just got it, take it back and make it an SEP.

if i were to repair a burnt valve would it cost much?

The best thing to do, is take the bike back to the place you bought it from as amorti said!
The bike should be running and fit for purpose. Unless you bought it nowing it had these issues?
You need to know whats wrong before you start thinking about costs of fixing things
Do you have a haynes manual? if not get one as they are well worth the money.
But get some new vacume hose first, then check the charging system. Both of these are known issues and can cause the sorts of issues you are describing.
Cheers

yea ill prob bring it back there. maybe just sell it back to them and make it SEP lol

What, they don't have to give you any kind of warranty? That's shocking.
