Ok, I feel like an idiot. I took the valves out today while doing some maintance on the sled ( 04 ProX ). I got them nice and clean and wiped them down with a little oil to re-install. Then I realized when cleaning them I moved them around ( I originally placed them on a clean rag the way they came out ) and cannot remember which way they go back in ? It appears they will fit either way, but one way they are much easier to bolt in. Help ! I do not dare start the sled until I know for sure. :banghead:

Numbers up. The way thats easier is the right way.

I may be wrong, but I think they will only fit one way?

Thanks !!! :beerchug: That is the way I did it. Next time I will pay attention. :frech32:

Yes, the guillotines will only fit in one way.

On the plus side, they appeared clean, sled now has almost 700 miles and no real build up. It took me 5 minutes to clean them.

We've argued about this before. THE VALVES CAN BE FORCED TO FIT IN WRONG.
