9801srx said:the only way to check for a pull through is to remove the valves and have a look . pulling on the cables from the servo end will only tell if a cable is broke.
tyler66665 said:Just to add on to what 9801srx said... bring a set of alen keys with you and get him to warm to sled up a bit before you take the valves out because they might come out easier. All you have to do is remove the four bolts for each valve and pull the valves out to see if the cable is connected. If the cable is pulled through the back of the valve get him to take off $150 for every pull through because you will need a new cable and valve.
Let us know how you make out? Good Luck!
snomofo said:Not that I disagree with what tyler proposes, but if I have no idea who you are, I wouldn't let you lay wrenches on my sled. I may pull them for you if requested but I'd expect you to agree to pay for any damage to the gaskets if the valves are good. If he is hesitant, tell him it's a common concern and that if he doesn't know the condition (he should if the "top end" was done), you'll be pulling them anyway for your own piece of mind. May be a term of condition for the sale that brings the price down a bit.
