Thinking carbs are dirty, any input before I start tearing the bike apart? - Page 2

@Triple Jim @DannoXYZ I think I have all of the grommets!

Also, just wanted to ask this real quick.
I lost a fair bit of oil. Is there any way to change this oil without taking off the valve cover? If not should I just change/top off this oil now so I don't have to take everything off for a third time soon?

I have everything off and access to the valve cover right now. I just want to see if I should go get oil before closing everything off tonight.

Changing the oil doesn't involve the valve cover.

Is that the same oil that is in the top end with the valves? If so how does it get up there?

Triple Jim · October 1st, 2019, 02:21 PM

Yes, same oil. The engine's oil pump gets it there.

Wow, had no idea! In my defense this is my first time working on a 4 stroke haha

Yes, 4-strokes are evil. I've had this most of my life.

Last time I adjusted my pregen valves I found that is was necessary to tighten the four bolts right the way down using the old gasket to stop minor oil leaks. But I am guessing that you might not have it seated correctly as it really shouldn’t leak much even if slightly loose

@Triple Jim Wow that thing looks sweet! What is it?
@59096 haha yup, what I said below describes me making the same mistake

And to give everyone a final update, I'm pretty sure I've FINALLY finished the valve adjustment. The manual calls for something like 87in/lbs of torque, but the wiki says this can be achieved by hand tightening then one more 1/8th of a turn... this is SUPER wrong haha

I used my torque wrench and now everything is working, mind the other small issues I brought up earlier but I think those can use their own threads to keep things separate.

Thank you to everyone that helped me through this long process! I learned a lot from yall and I'm sure I'll keep learning more
