250-500cc Another Piston Thread

Powerseal USA in Pa did the plating

The D shape of the arm is the opposite of the shaft coming from the bottom end.

Ahh have you had the cover off?
If its not factory sealed seems like soneones installed the pv arm back to front.
Does the thing move when the bikes running, my guess is no.

Pull lefthand cover off engine can be in bike lay it on its side pull cover and put the shaft right way round then get pv governor and hold it in position on the cover with the pv shaft then reinstall the cover.
Done.

Yes.... Had to do the water pump shaft seal shortly after I brought it in 2011....

Do you have the snap ring at the bottom of shaft where it transitions from small to large diameter? Take a look at my photos.

So you probably have not had a power valve since 2011... Just take the side cover off pull the power valve "governor" out (the thing with the spring that connects to the lever) make sure there is a bearing on both sides of where the lever connects and install it back on the cover side and the D should be facing the right way.

Here is a diagram for reference

Maybe late 2012 ??!! Most riding is tighter woods....
But It's all to the correct position..

THANKS !

All the upper is but in exploded diagram #6 is 180 degrees out.
Pull the cover and check visually, never know it may of sheared.

Can you rotate the shaft clockwise through 180 with cover on?

Yeah looks like your missing the circlip too.

Somehow it (the shaft) was 180* rotated. Not sure where the mix up was, I must have looked at the exploded view and set it up that way?!?!? I removed the cover, rotated the shaft to the correct orientation and reinstalled the cover. It bolted back up and I can feel the tension of the spring when I tightened down the nut.

Circlip was there, just rotated so you can not see it well.

On the bright side, I learned a method to adjust the side power valves without removing the front exhaust plate.
This is how I left it last night... And cleaned the carb too....
Today was daughter's 2 game soccer tournament with a travel basketball playoff game in between.

Were you in pittsgrove for the tournament? My son has a 2 day tour. next week there.

Yes in Pittsgrove, Saturday was cancelled, still had snow on the ground late Friday night. So we played the Sat schedule on Sunday and they did a half credit to another EDP tourney later this year.

Looks pretty far away down there. I'm lucking out with the warmer weather this weekend. However, no riding!

Is there any way I can find out my bore\pistion size with out pulling my bike apaft first? I want to have all the parts before starting if possible. Is it stamped on the out side somewhere? My bike is a 08 wr250

Hi Huskynoobee

I see in your pic You have an ohlins shock. where can I get one? Was it custom?

Was the ohlins worth to money?

Thanks. I emailed the guy but he does not have the parts to make them anymore.
