Hyosung GT125R lacking power/losing power

[tom9405]

Hi guys

When i start up, the bike seems to idle/rev fine, but when i stick it in gear, and accelerate, i get barely any power.

If i cut the accelerator and then go again, this seems to make it work, and i can buiild up speed as normal.

However when i get to about 60/65, I start to lose power/rpm again.

I've changed the plugs, and checked the carb. The carb seems to be pretty spotless.

Air filter looks almost brand new, as the bikes only done about 3500 miles.

Anyone got any ideas on what this could be? I've had a loo around and seen a few people with similar problems, but nt quite the same as mine!

Any help greatly appreciated!

You will be doing well to get that bike to 65mph in the first place.
