Whats going on fellas I got a 98 200 blaster that has set for 5 years I cleaned the Carb out twice jets are good to my knowledge. Got good blue spark I put my finger over the sparkplug hole got good compression not sure if compression is 115 to 120 psi. Took head off good gasket and sealed back with copper spray on gasket. Valve reeds were bad. Rednecked them with credit card's they seat well and you can't see any daylight. New gasket for valve reeds. It will start for a short period of time as long as I'm being pulled or down hill back fires here and there and blows white smoke.

Can someone help please driving me nuts that can't get it to run

I think you should get a new set of reeds and a gasket kit

I had same issue with mine It sat for six years and changed the reeds and

got a gasket set for like 20 bucks now she starts first kick

Idles good but have to give it gas to start and the dealer said they cleaned the sh** out of it when I took it back with the issue

Well I can't find an exact number but I know

a stock Honda 300ex is 16-18 rwhp

so with the smaller engine and being off brand probably

10-12rwhp

Okay so I need a little help

just picked up a brand new 2012 yfz450 carb model

being that it was a left over I thought my cutting out issue was bad fuel

but even after draining the tank and putting fresh gas in it

after riding for about 20-30 min in the trails

if I hit the throttle wide open it cuts out bad (doesn't die though)

it won't even climb hills

and the one time it was so bad my buddy beat me on a stock 300ex

my yfz is completely stock

no mods at all and I have tried taking it back to dealer

but since it mainly is after some trail riding

they can not replicate the problem

someone plz help

I've only been able to ride this for one tank

of gas being its running like chit and have to turn home at big hills my buddys chit quads climb right up

Did u find out what the problem was I am also have trouble with my 2012 yfz carb model

when I go out to ride it runs good for a few minutes

but 20-30 mins of trail riding I go to wot and it cuts out very bad

won't climb any kind of hills at all

I even got beat by my buddys 300ex lol
