Hi, I'm new to this forum. Just got my Yamaha DT125 R 1999.

I have a little problem with it, it runs fine at low revs but as soon as it gets to around 6000 revs it bogs out, also as soon as the throttle is opened fully it does exactly the same. It's not a restriction as the amount of revs it bogs at changes every time. Thought it was a dirty carb but its not that as had it all cleaned up and didn't stop the bogginess. Been told it could be my coil so I've brought a new coil.

Any other ideas on what it could be?
