I am sure there is engine assembly lube available in Belgium. It doesn't have to be paste, modern assembly oil style lubricants will provide great protection for first start up.

I wouldn't use qtip on the drill but do it manually, polishing float valve seats was also one of the steps in manual I posted!!!

I don't know why are you guys afraid of using PROPER SIZE guitar string!? I followed this carb rebuild manual which used guitar string and my carbs are working flawless! Highly recommend these instructions, but please don't skip steps and take your time!

This is not related to your bike running but when you get that bike running and it is running while standing still, make sure to have some fans blowing at that cylinder head...

Now we have complete For Sale posting! ;)

For...?

I will go on the limb and ask what is HM 300!? You know, wise man once said picture is worth 1000 words!!!

Can you make those pictures a ailable to us so we can see the process and parts used.This would be good info for some of us who decide to go this route! Thanks

I sent you PM in January about motor, no response!?

If you don't like that 81-82 F tank, let me know if you want to sell it!?

I agree but as I stated before, if ONE wire strand is good and all other broken you will still get GOOD continuity! True continuity test is voltage drop. Just a thought, can you run new test wire if it is straight wire and not spliced one!?

True that doesn't happen but how we end up with fuel coming out of intake boots when piston on intake stroke creates suction!?

Guys basic engine operation, if proper amount of fuel is introduced to the cylinder and even if that cylinder does not fire, that same amount of fuel will be compressed out of cylinder into exhaust. If we have SO much fuel that is pouring out of intake boots than we have exorbitant amout of fuel...

True but that would still be on him and if that's the case he is paying for it now.

Obviously you missed something or did something wrong! I rebuilt my carbs following these instructions once and my bike started right away with no issues and only needed minimal adjustment during sync procedure. Since you said you have carbs out I thought to share these instructions with you...

While you have carbs out, follow these instructions and you will be golden on carburetor side...

Found.

When you overhaul your carbs use small Q-tip with some fine polish and polish float shut-off valve seat!

Hi all,looking for CB900F oil pump assembly in good condition, please no pump from failed engine. Much appreciated, Bo

According to web search CB750C (RC06) production ran from 1981-1983 so your being 1984 doesn't sound right. Now this info apply to US, maybe it is different for Europe, since you are there do some research.

Look at plate on your steering stem neck for manufacturing year and model, also snap a picture of calipers you are searching pads for!

In!

Lol, I am not trying to convince you about anything but maybe eye doctor appointment is in your close future. Here is few pictures of head not painted inside, not painted but oxidized and painted head on inside (not exact chronological order but you get the point)

No paint anywhere but cast parts like head and block. This motor was not spray bombed or anything of that sort, this I factory finish. Val e train and all associated parts are clear of any paint like finish. Here is a link for RC04 head for sale and is painted inside...

I wish I took pictures when valve cover was off... basically whole head inside is finished in black color with few spots showing raw aluminum where paint flaked off. As you said disassembly of the head to remove paint is out of question, motor has 16k miles and running like charm, no need to...

My engine is black and with certainty I can tell you head is painted black on inside not sure about rest of the engine. I should have taken pictures when valve cover was off...

Hey guys. I had stubborn valve cover gasket that would leak until engine came to operating temp than it would seal up. Amount wasn't bad but it was enough to bother me. I decided while I am taking the cover off may as well check my valve clearance and while doing that I noticed black paint...

While you are there HAND polish vacuum piston sides, bore and cap (inside). This will really improve your throttle response. For your missing rubber plugs go to Amazon like Brett said, they have variety pack of silicon plugs, I would test their resistance to the gas first before putting them in!!!

In!
