93 blaster stalls and backfires low rpms

[cenzo4dub]

i was riding the other day in the snow for about an hour or so and i was doing a couple of donuts and i dropped the rpms a little and it stalled out, since then (a couple days ago) it has been backfiring a bit and stalling unless i rev it high. it is mostly stock with just a fmf pipe i have no idea if it is anyhing else done to it as far as motor work. any advise on what i should look at first would be aprriecated thanks
it was also very cold the 2 days this happened and i havent tried it since

When it runs, does it sputter or does it run smoothly?? Might try checking the reed valves to see if they decided to go out on you.

^That was My first thought too.

it runs pretty smooth as long as i keep it above like 5 or 6k rpm
if it is the reeds whats the best kind i can put back on and do you recommend the intake spacer as well or is it even worth it to put performance reeds on stock motor

 

[Braapbraap95]

Intake spacer is questionable, but hell what is it 20 bucks? and best reeds are either boyessen or vforce.

i put in 93 octane that mix could that be affecting anything

i doubt it i use 93 all the time with my stock engine.. maybe the sparkplug isnt hot enough? check that Cuz mine did the same thing and it was the spark plug try br9es and if thats whats in it try br8es you can pick em up at autozone or autoparts stores. the brand is NGK
