Question about 1986 Yamaha RD 350
What is the lowest compresion you can have
Anything under 105 psi you definately need to rebuild your top end.new pistons/rings and a bore.A stock cylinder banshee with factory pistons should average around 125 psi.After a bore and new pistons you will be around 135-140 psi

The bike will still run even at 7:1 or a little lower, but the specifications call for about 10:1.
