Problem at high revs

[littlejohno]

I changed the oil and filter on mine today along with the air filter.
Prior to this it ran fine but didn't pull like I thought it should but I only got it Monday.
I also had to take 3 litres of oil out side to overfilling but the bike ran as above.
After changing the above items it now holds back at around 6,000 to 10,000 then pulls like a train better than before this is in all gears.
I can't see any pipes trapped either !!!!!.
Do you have similar issues

I would suggest its the air filter - swap back to your old one and see if it still happens. What was the new air filter you put in? Most (including myself) would recommend a K&N

It was the exact replica of the one that came out I couldnt give you a name.
The old one was contaminated with oil due to the overfill.
Its strange as when it does rev clean it's much stronger parts will be coming off lol
