Can someone who did the bottom end tell me for sure?i dont want to make something wrong.

I agree with you but my concern is that this model has the extrernal oil reservoir tank over there and so if there is not sealant over there maybe the extrernal oil reservoir will not show the correct amount of oil because the oil will flow into the crankcase

hi guys.i have a yz450f 2006 model and i rebuild the bottom end due to bad rod bearing.i would like anyone who knows if i should put sealant also on the red marks in the picture below.on manual there is not show any sealant overthere but this is the place where the oil reservoir keep the oil to circulate so i think that it must be sealed.please see the picture and if please tell me if anyone knows the correct way to do it.i repeat that manual doesnt show any sealant overthere as you can see in picture below .thanks in advance

ncmountain writes that i should ground the negative lead to the rectifier bolt.i can not understand what he means when he says negative lead.the two small black wires where are connected to the negative lead of the battery with the main grounded cable which goes to the starter?

can someone help?

I would like to remove the battery and the starter components of my wr450 2003 cause i dont use tje electric starter and the bike starts on first kick.somewhere i saw that i have to ground the negative lead whoch connects to the negative on the battery to the regulator. As i observe the negative lead is also grounded to the starter bolt.can someone explain me what exactly cable i should ground to the regulator?also if i will remove the starter i must leave the grounded cable on the starter connected to the engine?thanks in advance.

today when i was driving my wrf some noise occured and i shut down the engine.some of the clutch gear bolts on the flywheel fell off and the stator is like a crap.i decide to remove all the idle gear, starter clutch,ellectric starter, battery, because my bike starts on first kick every time but now i need to replace the stator.can you tell me if there is any option to use a stator from another model of wr450 or yzf450 because i can not find any cheap stator from 2003 model.do you know if the newer models have the same stator as mine?also the bolt made some dents on flywheel. do you think that a new flywheel is needed?it has three dents about 2mm deep.thanks in advance guys.

i think is a bad solenoid.when i by pass the solenoid with a screwdriver on the 2 upper bolts the electric starts works fine.so i will give a try with another solenoid (starter relay).

do someone know if there is any ground on the frame?

the bike is wr450 2003.thanks a lot for your help

is there any ground on the frame?

i own this bike two years and never this happen again. i know the tdc issue but if i push the electric button two three times it starts fine.i think the problem is bad earth/grounds.can someone tell me where are the grounds on this bike?

do you know where are the grounds on this bike?where i have to look for bad earth/ grounds?

in last few days when i try to use the starter sometimes (3 of 10 times) it just click.the battery is new and fully charged 13v.the solenoid does make the clicking sound.i think that the problem is a bad earth/ground. can someone tell me where are the position of the grounds to check them for corrosion?if you have also any other information please let me know.thanks in advance.

Thanks for the info guys.i just turn in my fuel screw a half of a turn and the choke works fine now.....maybe i had my fuel screw to rich.the bike works fine now with no bog on choke.
