Hi everyone, recently got an old (1990) Rm 125, the bike is in quite good condition for its age, however it needed the powervalves setting up correctly when i got it, having done this the bike seemed fine and was hitting the powerband nicely. I was out with a couple of friends riding at the weekend and we had to go down a few roads, off the road the bike was working fine but as soon as we hit the roads and i opened the bike up it was 'bogging out' as soon as i put it in top gear, like it needed to gear down to regain power.. but when i did this it was the same in every gear even in 1st & 2nd! Only then would it pull properly again if i came to a complete stop and went up through the gears again.. YET as soon as i got back off road, and was riding on the mud again, still hitting the powerband but not for as long and not all the way into top gear, it seemed fine again!

crazy post i know but any help would be greatly appreciated!
