Question about 1981 Yamaha XJ 650
I bought this motorcycle at a sale. it runs but it keeps reving up instead of idleing. I've put new intakeboots on and new needle and seats in all the carbs. but the problem is still there. Also seems like No 2 cyl is not hitting I get no change when pulling spark plug wire off that cylinder. I did a compression check and had 70 in that one and 90 in the others.is this too low of compression?
Any advice giving would greatly be appreciated
