I cant seem to get my valves out. The head is off the bike and all, but i cant seem to get the rocker arms out if that is what i need to do... All 4 are warped so its time for new...

:help:

Did you pull the rocker arm pivot pins out? You have to use a small slide hammer or an extraction kit....they're kinda pressed into the head.

ok cool, thanks. does anybody know the right thread size?

Spartan

I think it is like 6mm but not 100% sure.

russ-russ

It is 6mm.  You need abot 8-10 inches of all-thread and a nut to use it as a puller.

of course the home depot by me doesnt carry metric all thread  :mad:

Spartan

Ace hardware...Or you can just get the kit from DL700. I think it is about 20 bucks...

Livingmylife93

so of course no where around here has the 6mm all thread... my parts are in today and i could get it back together but need to put the new valves in. so as of now its holding me up  :(

i know somebody on here has an alternate method to get the valves out?

Spartan

Get some standard all thread that is close to 6mm then use a metric tap on it to re-cut the threads to metric.

Krandall

Its rough cutting standard to metric. I'd suggest finding steel rod and cut threads that way.

That'd work too...Or get a longer metric bolt and just put a nut below the bolt head to push down on the spacer. I am not sure how long the ones in the "kit" are, haven't tried one myself yet. I've also heard of people using a small slide hammer to pull it out

i can get normal steel rod, then what do i do with it? how would i thread that?
