Cleaning VES valves

Never had anything in way of pulling exhaust valves.
Went to pull them to clean on my RMK 600. Mag side no problem, bit the PTO side hits the lower steering post. (Pitman arm?). If I take out the 2 bolts holding it to the upper structure and disconnect the link arm, will it move enough to get the valve out. Or will I need to unbolt the tie rod and cross link on the bottom?

Sure is PITA to have to unbolt the top of lower steering post to get a exhaust valve out. Enough play in all the linkages that by turning bars hard left, and pushing steering post . Can get the valve out. But even had to take plastic cover and spring off to make it clear. Never have had to disassemble a VESvalve to remove it from motor. Then of course I drop one of the sleeves (bushing) that keep the bolts from crushing the plastic mount. Couldn't find my telescoping magnet to fish it out. Finally got my fingers on it, but got a couple scrapes on arm from muffler.
Good thing this is something I only do once a year, even though its recommended every 500 miles.

Yup, experienced the same fun (including dropped parts) when pulling the valve on my buddies sled. Now we know the drill. And yes, you have to pull the valve cover too.

Makes me feel better, others drop stuff, and learning from it. SO MUCH FUN. Be doing Austins 15 assault 800 next. As soon as he picks up from his Aunts house where it's stored. Be a little better, "Now we know the drill."

It was always a pain to clean the exhaust valves & the slot they slide in every 700-1000miles in any polaris. don't forget to clean the pressure port. I use a long small drill bit that I turned by HAND. If the port is plugged, the valves won't open. This port does get plugged with the same stuff (carbon) that gets on the valves.
