My specs are .08-.12 mm for the intake and .10-.14 mm for the exaust. Miy specs are on a label that shows what spark plug and gap to use, What the idle speed is and the valve specs. You could also call a Yamaha dealer and ask the service dept. to be sure the specs are the same.

 

thanks a lot thunderbolt, I appreciate it. I already called a dealer and they said the same thing for valve spec. what plug do they recommend, and what gap?

is there any spec for the carb mixture screw (i.e), 1 1/2- 2 turns out? I asked dealer about carb, they didn't know (=lazy and don't want to help me). I never asked them about the plug.

Thanks again for your help.

 

I'll check on the plug when I get home and I am not sure about the carb settings, But I don't think it says anything on there about that.

 

Confused, Looks like your getting some info on your Breeze[img]i/expressions/face-icon-small-smile.gif[/img] Talk to you later in the 7.3. Lt. Dan

 

adjusted valves last night. all your info was extremely helpful. mine has the "h", then a dash line and then a 'T'. I used the line.

After checking VIN, turns out I have an '89, NOT a '95. I posted another thread for maintenance info on this thing.

 

Glad I could help!

 

what are the specs for a 1989-99 yamaha breeze head bolts?

 

for the intake valve tighten down then back off 1/8 of a turn,for the exhaust valve tighten down then back off 1/2 turn while on TDC this is almost perfect and works on almost all stock 4 stroke quads regardless of size. hope this helps.
