When you have a bent valve do you have to replace the valve guide. and and also haveing it being a thousants of an inch. would that even mater.

yes it matters...no you dont have to do the guides

ok thanks i had another atv shop cheak my valves, my other intake walve was bent also. would that also cause the valve guide seal to waer out. it was bent a litle more then the other one. and i checked the seats before all this, i put gas not water this time. and it leaked worse, i guess thats why it would smoke when gassing on it. but im pretty

.....................your pretty?

"""but im pretty"""


we need pics to prove it!


but your valves could have smaked your piston/timing chain jumped?

i would figure out what it is before you put new valves in and bend them to....

i thank the first time when i went to rebuild it. when i tryed taking the head off we didnt take the motor out when we forced the head off we pressed the springs inrared and i thank that what bent them, how hard is it to bend the valve.

Really easy for a knucklehead

[350xrider911]

so that what could of bent my valves. scence then ive learned to take the motor out it makes thang alot easyer. what would cause rings to stick to a piston running to lean im guessing, or not the right rings?

[Dirtcrasher]

I really feel for you guys..... I've built numerous motors and never had rings stick or valves bend, aside from when I was about 14yo and uneducated in the motor department.

But, I think some guys think it's a piece of cake and overlook allot of simple but important suff and in the end, it costs you ALLOT of cash to get going again.

Stay here, keep posting and read an OEM manual soup to nutz.

plz help me and not insault me.

No-one can be helped with rebuilding a top end on a 4 stroke in just a few posts. There is a ton of little stuff that has to be right for it to last.

Ever wonder why OEM builds last 20 years and 30 days after someone puts rings in it's apart again??

[350xrider911]

im pretty sure, i did the rings right gap and every thange. i put new valve guide seals. and it ran right for a couple of days, then i start it up one day and it smoked for a while. then stoped after warm up. could it be the mistake that i did bending the valve causing the valve guid seals to wear out fast.

[Somekindofjerk]

If you dont do a valve adjustment right, or dont degree the cam correctly you can cause smoking and or damage to not only the valves but allso the piston. Im more willing to bet the bent valve was causing low compression causing smoke and loss of power...

Did you clean the ring grooves good? You can use a piece of an old ring to clean them.

[350xrider911]

yeah the mecanic down, the street told me to spray the stuck rings with carb cleaner. cuz he sed the way i drive i made the rings stick by carbon build up. because i can only drive in the yard pretty much 1 st gear. on the valves i bent them cuz i didnt know what i was doing the first time i thought you could take the head off while the motor was still on the trike.
