Problem... I rode the bike one day and everything was fine. Next day when I started it, it was puking oil out everywhere. I found out that the seal around the shaft the front sprocket is on has popped out. I tapped it back in place.. seemed like a nice tight seal, started it up and watched it get slowly pushed right back out again and oil dump all over. Why is the crankcase building up this much pressure? Plugged hose/vent somewhere? I don't know where the vent is on this thing.

Thanks.

This is not unknown. It happened to me on a cold start so I made a mechanical retainer. I ended up making and selling a stack more. I don't do them anymore, but Procycle does. Get one, bolt it on and problem fixed. And for others out there, do it before its a problem as insurance, because when it happens it really is a PITA.

My story starts at #197 here:

So there isn't a plugged vent somewhere? This is just one of those inherent things of the bike?

And.. I've never seen what you're talking about on the regular DR650 page of Procycle. Is it listed somewhere else? Does it have an official name?

Rear Brake Lever

Hey guys - are rear brake pedals all the same? Bent mine up pretty good and plan to put a new one on.

Thanks

that thing isn't too bad.

This was as far as I got by 5pm today. Maybe have it wrapped up tomorrow if I'm ultra super lucky.

I've never seen an aftermarket replacement. I think it's just mild steel so you should be able to bend it back into shape. I've had to do it with my shift lever.

The question has been asked: "How heavy is the DR engine?" You could tell us here AND post it up in Krusty's DR Index (Hiya Krusty, thanks again for the DR650SE INDEX ). Or you could let us down and be forgotten forever.

I just know it should be 1ounce lighter now than it was before

I'm sure you're correct. Removing all that alum from the piston for valve clearance must be good for a multiple of pounds.

noob question, why do you have to remove the motor to put the new high comp piston in? Can't it be done whilst motor is in the bike?? I'm sure there is another reason.

I'm not sure if it can be. Seems like there's a real possibility. Someone will undoubtedly chime in that knows for sure.

But by the time you have it far enough apart to attempt to remove the jug in the frame, it's three more motor mount bolts and a couple other misc garbage to have it on the ground. Literally less than 10 more minutes to have it on the bench.

Too bad my bench is over flowing with other garbage and there was no room for the motor.
