Hello
I've got some strange whistle coming from the engine when the bike is moving.
The sound is louder if I accelerate and nearly disappear when I slow down.
Anybody knows what it can be (and how to fix it)?
(this is a stock 1993 LS650P with 26.000km (16.000 miles))
If you wish I can try to record the sound and post it.
And I've got another question : does anybody here ever experienced the RAASK Dragpipe (6") exhaust line?
Will it improve power?
Is the sound louder?
Ho, another question (last one). I'll change the oil (and the filter) soon. What's the best oil for this bike? Synthetic? Semi synthetic? Non synthetic?
PS : please excuse my poor english, this isn't my mother tongue
