Re: Dewey’s CB750 K2 - Breather Hoses
« Reply #104 on: October 12, 2023, 08:35:44 AM »
Read all the threads about breather hoses. Just want to verify for my K2. The cylinder head cover and top nipple on the oil tank are vented to the atmosphere. Were they originally T’d together? What is the best way to route them? The bottom nipple on the oil tank (overflow?) is connected to the rear nipple on the crankcase.

Has anyone found suitable hoses at NAPA? I fitted a hose between the oil tank and crankcase, but need to find something that fits the cylinder head cover and top oil tank vent (~12mm). Also looking for fuel lines (5.5mm) and overflow lines (3.5mm) today.

Re: Dewey’s CB750 K2 - Replacement VIN Plate
« Reply #108 on: October 15, 2023, 02:29:50 PM »
The PO had the frame powder coated and the VIN tag was missing. I ordered a replacement and got it installed today. The rivets are about 1.8mm wide. A 1/16" drill bit is about 1.5, so it worked well. I formed the tag around a piece of pipe to get a curve in it. Recommend drilling the first hole and installing the rivet, then drill the second hole and install the second rivet.

Yep, that's just how mine looks. ;)
I get fuel line from Honda as it fits right and lasts long. However, for the fuel line there is a polyethylene type (I think from Motion Pro?) that is hard to get, but makes better fuel line if you have to remove/reinstall the tank very often.

Tygon? Like used on weed eaters and chain saws?
Tygon gets stiff due to UV if I recall correctly.

Not sure what constitutes a full tool kit, but this is what was in the bike. I know I'm missing the screwdriver handle.
