open throttle - not smooth

[mealexme]

As title says, if the throttle it heald open fully, it gets a bit... choppy - its not smooth. I have had this problem since i have had the bike.

I had a little look on google and couldnt find anything

Can anyone recomend anything? Hopefully its something really simple as i am not confident in taking it apart and cleaning carbs etc :s

Thanks, Alex

I had the same problem with my 50, the garage replaced the spark plug and it fixed it.

is it at a certain rev range?

the mixture could be out the needle in the carb might need altering it could be operator error

if you planning on doing full test i would learn to live with it and save your money if its not too bad

is it at a certain rev range? havent really noticed if im honest, i dont think so though

the mixture could be out the needle in the carb might need altering it could be operator error that sounds about right haha

if you planning on doing full test i would learn to live with it and save your money if its not too badI think if its not the spark plug then i will save my money, but just because I pass the test doesnt necceserily mean i will be getting another bike

I'd agree with the above.....sounds like it could be the plug or coil/ht lead.

When you say 'choppy' Alex, what do you mean?

When I'm on full throttle on my YBR I can feel like little hiccups/splutters sometimes - Is that what you mean?

I mentioned it to the guy when I took my bike in for servicing yesterday & he said he'd take a look, but he did mention that it sounds like some air getting in somewhere!

Mine is an 06 plate YBR.

It's gone into the workshop for a long-overdue service and some much-needed TLC, so it could be what he said or a combination of things!

I'll let you know what the diagnosis was when I've picked it up.
