[img]i/expressions/face-icon-small-smile.gif[/img]Ok,get the compression reading and go from there, I hope the owner before you rejetted it when he put the FMF exhuast on it Man I have seen to-many guys just put some PIPES on-em and ruin a good motor, or get-em where they dont run as good as a stock one, i think yamaha mite have it figured out!!!! They didnt change that motor >ANY< in 20 years,,1986=2006.IMO,,,,, Luck Eddie.

 

basically wen u doin the test do u have 2 take out both spark plugs and connect compression tester two one side and kick it into the needle stops is that correct or what can u give a lil directions

 

[img]i/expressions/face-icon-small-smile.gif[/img]Yep, just pull both plugs,its easyier to kick over,check one cyn,and then the other,really the first good kick should tell you what the pressure is,,,, but you can kick it a-few times to be sure that the gauge is OK. It fires every stroke so it ANIT going to build up pressure to run on. Luck Latter Eddie.

 

[img]i/expressions/face-icon-small-happy.gif[/img]Also T when you do the Compression hold the thottle wide open, i forgot to tell you that. Latter. Eddie.
