I have a question if anyone could help me I just got done building my yfz 450 2004 top end and I timed it and stuff ran good as soon as I was done road it for about a day started it the next and it lost a bunch of power and starts to bog out and cut out when I push the thumb throttle in about 1/3 of the way it makes it backfire bad two if someone could help I’d really appreciate it
Sound like the waterboy 😂😂 I definitely was doing 15 pins then went to 14 pins and then now im doing 13 pins for sum od reason my bike cold or hot would slow crank with brand new starter nd battery i changed the exhaust cam thinking the decompression was faulty nd for now its been starting very easy cold or hot will go for a long ride tmrw
