Thank you. I'll probably pick up the new o-ring from the honda shop for that oil tube.
Thanks, I'll stay away from them.
I still might go OEM. Depends on if they have it in stock.
Sweet. Merry Christmas, but it looks like you all ready knew that.
Merry Christmas guys........
I'm all jolly. It even has the factory tool kit and owner's manual including lanyard cable extension to helmet lock. Hopefully I can flip my old bike soon enough to not feel the pain.
So like I've got this XRL motor that was in my old XR when I bought it. Low miles, but due to monkey service by PO, they broke the cam gear bolts and munched the top gear. So I changed the top gear, chain, guides and tensioners.
Engine develops a bit of a top-end rattle after a half hour or so of riding. I'm thinking when the oil gets up to temperature. My suspicions are worn rubber o-ring on right side cover causing low oil pressure (I didn't change this when I had it apart) or possibly the wrong spring under the pressed-on cam gear (things went flying in the garage when I pressed it off). Does anyone have an actual photograph of the cam decompressor springs (not parts drawing)? Engine seems to run good though.
Your fucking killing me. Now I have to break out the camera and take the cam apart.
Hold on, it'll be a while.
I always wanted to see what the insides looked like. Now I wont have to tear my spare apart.
The above picture shows the spring and roller at the 2' position incorrectly. The roller should be on the other end of the spring. It fell apart and I installed it incorrectly.
The above picture shows the correct orientation of the rollers and springs.
Thanks for posting the great photos, Steve.
Pages 9-7 and 9-8 of the new Honda Common Service Manual describe how the automatic decompression system works.
This information is not available in the old version of the Honda Common Service Manual.
It appears the decompression cam will be held in place on the camshaft by the spring pressing it away from the camshaft. However, if the camshaft is tilted downward, the one-way roller bearing and the reverse decompression cam could fall off the end of the camshaft after the cam sprocket collar is removed. :huh
Steve, Man you are awesome! So I wasn't worried about the 3 Decompressor springs, but rather that one that slid into the cam perpendicularly with a pin too. So was it like that spring was super light tension? That last picture was gold! Looks like I have that right. I'm suspicious of that o-ring on the pump now. I definitely put it in, but it was tattered. Something's making it a tad rattly up top.
This is why I love my XRL. It's the people!
Merry Christmas fellow BRPers!
Merry Christmas, everyone!

MERRY CHRISTMAS one and all !!!
Merry Christmas everybody!
Spring #6 can become a problem when it loses it's tension. My son's bike would not start when cold and I found that the engine would rotate around to TDC with a pressurized cylinder and not be able to get past TDC due to the decom not opening the right exhaust valve. I finally replaced that little spring and the engine would start normally again. I have a buddy's bike that is doing the exact same thing and we will be replacing the spring this coming week.
Merry Christmas Yall , .
Amen friend.... Being from Texas, isn't it All Y'all????
Merry Xmas to all!!!!!!
