Pro-X steel intake valves - Need Help

Recommended Posts

I just started installing Pro-X steel intake valves that come with springs. The springs that came with it are about 1/4" shorter than the stock springs and they don't have quite a big enough ID.

Did I get the wrong springs?

Any experience?

Thanks for the help.

I think I answered my own question. The springs will fit over the mating parts when pushed with a little pressure. They are shorter, but stiffer, so I think I have the correct springs.

I didn't get the seats cut. I decided to try lapping the steel valves. The lapping looked good. The bike runs great. We'll see how long they last.

They didnt have a big enough ID? What was interfering with the springs when you put them in place?

I would double check them. I just installed the same exact kit in my 04 250X. I didn't really pay attention to the length difference, but the new springs dropped right into place. Normally drag on the springs is not a good thing.

Two rides on the new top end and all is good so far!!!:thumbsup:
