Ok so as i was on my way back from a rally and the temp. just a little above 100 deg. i was going around 85mph when i started to loose power and jerking like when u vapor lock after a few miles it started to run fine again for about 10 min then started to do it again, has any one had this happen to them? also my uncle was having the same thing happen to him today as well and he rides a yamaha. Any one have any info on why this is happening?
