I have a 1992 yamaha blaster and it will not idle. i can hit the gas and let off and it will die instantly. I dont know what is wrong with it. I dont know if there is something blocked or what but if someone would happen to know just let me know or if you have any suggestion Thanks Austin

Also i need to know the mixter for the gas and oil i have been told it is 32:1 but i would like to know for sure.. thanks again Austin

 

32:1 will be fine

 

When was the last time it idled properly? The idle adj might have gotten unajusted. How dose it run at very slite throttle openings ( at all engine speeds) when you are ridding? 32: 1 is Right on your pre mix

 

I dont know when the last time it idled right.. i just bought it yesterday.. It runs okay at low speeds and runs like a top at high speeds.. When in like 1st or second gear it bougs every now and then.. Thanks Austin

 

your pilot jet may be too big

 

Check the Idle screw. remove the seat and locate screw on very top of carb. Now I can't remember what year they came out with the TROS. Speedy what year would that be? If not equipt whith TROS, Find screw that regulats throttle valve lowest hieght and adjust. I would adjust Idle before diving in to deeper issues. how ever mak sure pilot air screw is set to spec before adjusting idle.

 

I have one more question to add.. Is it okay to ride it like it is.. Riding the blaster like this wont hurt it any will it? thanks austin

 

It won't hurt it, but you want opptomum preformance and throttle response. you won't get that without proper idle. if you don't know your way around your carb, get a service manual. beleve me its worth it. if its not the idle Adjust screw, then take carb apart and clean, and adjust fully. while apart check float level. your machien is stock (no mods) Right?

 

Ya it is all stock except the pipe

 

Do you know where the Idle screw is on the Carb? Do you know where the pilot Air screw is? if you have an after market pipe you may need to do some rejetting as recomended by speedy.
