So i've been posting a lot, and i apologize guys/gals. So as you all know i bought a 2003 yz450 recently. A few misc things here and there have been wrong with it, nothing major i guess (so far). I had the carb cleaned/rebuilt with a new rebuild kit. The guy there wired up the pump thingamajig for me. I'm no longer leaking gas outta carb overflow. I replaces both the header exhaust gasket and midpipe gasket. I repacked the silencer.
So before i put gas tank back on, i checked antifreeze level. And noticed i couldn't see it. tipped the bike sideways, still nothing. hrmmm. So i bought some antifreeze (peak 50/50 diluated). and topped it up. Upon firing the bike up i noticed it was pissing out the hole just under the water pump quite a bit. I decided just to go up the road quickly and back to make sure everything was working carb wise etc. a few adjustments of the fuel screw and i got it idling well, pulling very very hard, and very minimal backfires. It is still backfiring, initially letting off, i have no backfire. after being let off throttle for about 6 seconds from a high rpm, it starts to pop a bit as it gets lower in rpm's in longer successions. (its pitch black here, and when it does pop, it pitches a 6 inch flame out of the silencer.) not sure if this seems right or not, but it works for me i guess. no bog hitting throttle, no hesitation at all. i pulled in the hotstart, while idling and idle went very high, which seems like thats working well =)
Anyways, after going up the road and back about 4 times. i stopped and noticed the water pump hole was no longer spewing fluid. Does this mean the seals are going, and once they warmed up, they started sealing properly?
from the few posts i read about other bikes, it seems thats the sign your seals are going in water pump. guessing same holds true for this bike? I at least wanted to get in a ride or two on this darn thing. *sigh*
oh, and once i put it back in my garage, i took the airfilter off to oil it for my ride on sunday. there was a red UNI filter, covering a yellow filter. So it was two airfilters technically. over the airfilter frame thing. Is this correct? Seems to me, it should only be the skeleton frame for the airfilter and a single filter only. not dbl?
Sorry for the multiple questions.
