Challenges with RD07 engine on around 4500 rpm
Got my bike out of garage last Friday after a winter storage here in Finland. Has been a blast, only challenges being ice on the road (not plenty), cold fingers (it's around 2 degrees) and that engine tries to stall every now and then...
When tachometer shows around 4500 rpm, engine sort of dies for a split second only to come alive again. This does not happen all of the time but every 20 seconds or so. Sometimes it is really bad and there is a series of power losses this way. This is not related to an engine temperature nor velocity for the bike (read:speed).
It is the same at least to around 5500 rpm but sometimes I can ride like 5 km without a hitch.
The question is, you guessed it, any idea why?
No bike, sad man...
