I recently acquired a garage queen. It has spent nearly its entire life in a semi-climate controlled area. 640 miles new. Two small scratches on the tank but otherwise appears perfect. But I am trying to find out whether the tires are original. They are Bridgestone's and I think they too are originals but I thought it was odd that Honda used Bridgestone's. Does anyone know what brand of tires were factory originals for a 1978 Hawk II with the Com Star rims?
Thanks..

According to Partzilla it was a Bridgestone or a Yokahama.

The Hondamatic came with the Yokohama. So the Bridgestones are right. Please don’t ride on those if they are the originals.

I’d like to see pictures of this NOS bike.

Without pics it didn't happen!

I will be happy to post pics. Just need time to download them first. Give me a few days to figure out how to do it. All help is appreciated

Someone requested pics. These are all taken when I first got the bike home. Nothing was cleaned up. I put fuel in the tank...no leaks...but gas did leak out of the transfer tube linking the two carbs. I have pulled the carbs. Flange between the carb and engine is in perfect shape and the carb throat was clean as a whistle. Float bowls did have dried crud in the bottoms, presumably remnants of gas that evaporated over time. I am convinced this is a true 640 mile garage queen.

Sorry about some pics being doubled. Still trying how to post here. I will take some shots of the tires and post them later.

Very cool.

I took a few pics of the tires. Besides the manufacturer's marks there are other markings. Some may be just inspection stamps but if anyone knows how to read the others I would appreciate the information.

Second, before removing the carbs (dried gas residue and shrunk gaskets) I read posts on how best to do it. Many seemed concerned about flange cracking or coming apart. Mine fortunately did not show any issues (a few pics attached) but the carbs were more than a job to remove. I was thinking about smearing some "red rubber grease" on the inside of the flange to make the carbs easier to install. This grease is made specifically to coat the rubber brake parts in older cars with wheel cylinders (remember those?) because it does not deteriorate the rubber. Has anyone tired this themselves?

Thanks so much for the overhead view with seat off. I just finished an orange 78 and the rear lights wiring routing was guessed at. BTW, I found an unused green female bullet ground that I left dangling from the main harness into the left side cover area. I wonder if yours has it, not shown in FSM wiring diagram, unlike the unused brown (taillight circuit) in the headlight bucket, which is shown on diagram. Perhaps for an add-on accessory. Do read Long distance Rider's sticky thread on VB carb rebuilding and be patient to clean the idle circuit. There is a tiny (0.4mm or less) passage about 10mm further in past the visible pressed in jet under the rubber plug. Cleaning this idle circuit is notorious for a redo due to poor idling. Nice cherry you got there, or perhaps blueberry. Also, sticker at rear fender and owner's man spec OEM tires.

Yes I greased my carb boots and mount cables before seating carbs.

MY 1978 CB400TII came with a 3.60-19 front and a 4.10-18 rear YOKOHAMA TIRES right out of the box!
