valves or seals?

[jeremy_283]

my top end is getting bored out just becuz of cylinder wear and tear....... do u gus think my valves or anything else needs to be replaced?

[underpowered]

i would check to see if they had sharp edges or had any visible wear. If not i would just repalce the seals.

[jeremy_283]

why seals?

[underpowered]

the seals are a general wear item. i you dont replace them now and put the bike back together, there is always a chance it will leak and cause the bike to smoke. and Who wants a bike that smokes? The seals are a cheap item and easy to replace. Much better to be safe now than sorry later.;)

are the valve seals o-rings?

[jeremy_283]

k i finally found it............. n/m i see there like $6.50 a piece ......... is it hard to replace hem while the cylinder is apart? how long does it take?

[underpowered]

if you have a valve spring compressor it is pretty easy. maybe an extra hour of labor to do it, if that. Vesrah makes them as well, only $1.35 each instead of $6.50.

wat about the term dont fix it if it aint broke? or do u live by if it aint broke fix it till it is? mine is just at a shop (not a dealer) and i dont wanna pay any extra labor

[underpowered]

yes i agree with the dont fix if it aint broke philosophy, BUT for the few extra dollar it would take to replace them i would. i say call the shop and ask how much they would charge to replace them for you. I do all my own work so it is only the extra $5 or $6 bucks for me, but if you want to risk it go ahead. I would not want to pay another hour labor , but them again, i dont want to have to tear it back down either.

i would put them on forsure so you dont have to tare it down later on because you are burning oil due to bad seals
