Yamaha blaster question

[mattsteibler26]

I gota blaster full fmf pipe 260 main jet. It starts and idles fine but when u crack on it it likes to cut out and spit like it has a fouled plug and shoot gas out of the carb overflow. i tried to clean the carb and air filter still no good. Any ideas?

float? maybe? ?

 

[mattsteibler26]

i checked to see if it was stickin. it not

check the float setting, and float valves rubber tip for rips/tears
float setting shoud be 20-21.5 mm measured like this...............

bend the center tab to adjust it

#260 seems a tad lean for a FMF, I would bump up the main a few sizes.

It may have backfired from the lean mix and broken a reed.

Mine does the same thing when jumping or going over a rough section of trail. i run an FMF fatty with a powercore 2 and a 280 main.

if hes running the stock airbox and filter with the lid on , the most you should be at is a 270 main . check the floats for cracks , make sure one isnt filling with gas and causing a problem , and definitly check your reeds , busted reed will cause you all kinds of headaches .

have a look at the reeds, perhaps got a damaged one
