Since I got my old 1979 xs250 back on the road in November I have been throwing the good wife on the back and racking up a couple of hundred kms each Saturday or Sunday.
Whilst I acknowledge the limitations of the old girl ( bike ) we have had a blast getting around Perth and surrounds after a few years away from two wheels.
The bike cruised around 90-110kph without too many problems up until just recently.
Now when under load on the open road it gets to about 100kph and then starts to loose power and the speed drops right down until the power cuts back in again.
I had had this problem once before under load going up a steep hill, now it does it all the time on the freeway or open road.
Apart from this the bike runs very well. It can redline in lower gears and doesn't miss a beat. Cold starts are terrible but thankfully I live on a hill.
Points have just recently been changed along with plugs by the local bike shop.
Plugs when I removed them were sooty, not sure if any clues there?
Any advice greatly appreciated.
