Help. Newbie with '85 RZ350 with odd sound

#1 Post by Swaler » Sun Sep 18, 2016 6:24 pm

Greetings all. I have an 85 RZ with 18,000 km on its first bore. I have only had it a short time but in the last week it has developed a new habit. It starts easily and idles normally. When I first start driving it has stuttering and making an odd almost wooshing sound from the front of the engine. This disappears when the engine revs over about 5500 rpm, and also completely disappears after the bike has run for about five or ten minutes under load. Any thoughts as to the diagnosis? Tks. Bill in Peterborough, Ontario.

one of the nuts had loosened off

Indeed that was the problem...I have to admit I was sceptical but there was a single lose nut on the right exhaust manifold and tightened it and voila no more odd noise. Thanks kindly again. Bill
