Mystery 1986 Hodaka frame info / ID help please!

Pictures for this post are in an album entitled 'mystery 1986 Hodaka frame', as I can't upload pictures until I've made more posts. With a previous mystery frame another member kindly posted the photos from my album, so maybe someone could do the same for this query? So, here we go:

I saw this frame going for scrap, and thought it might be worth rescuing - couldn't really see what it was due to the tasteful paint job and sticker-bombed stays - but the star shaped reinforcement on the bottle bosses caught my eye. Stripping the stickers and some of the general crud has revealed some other features, which I was hoping might help me ID the frame, but alas no luck so far. I'm hoping some knowledgable person will be able to point me in the right direction. Things I've found out that aren't evident in the photos are:
68mm bottom bracket
Evidence of removed braze on gear lever bosses, top tube cable guides and rear derailleur cable stop.
Derailleur hanger hacked off (presumably at the same time as above braze ons)
Seat tube appears to be something like 26.8 or 26.6, but hard to say as the clamp had been overtightened to hold a smaller seat pin, and had deformed the seat tube a fair bit.
Frame (without forks) weighs approximately 2.2kg (Ishiwata 022?)
TH 86 06 on bottom bracket could maybe indicate manufacture in Taiwan by Hodaka in 1986.
All original paint appears to have been thoroughly removed with something like a wire brush prior to purple paint being slopped on. Only possible evidence of original colour is inside the bottom bracket shell, which I've tried to show in one of the photos.
I think the above pretty much covers it - any ideas, anyone?
My plan is to see if I can get it rolling again as a runaround for my son - it would be good if I could give it a name

Any ideas as to what this might be then? Other than (currently) a heap of junk?!

I have no idea what it is. When I saw your thread title I thought that someone had started another motorcycle thread.

Yeah - that's a problem I keep hitting when I search the web for info about Hodaka bikes
however I have managed to glean from a few posts here that they made frames fo a number of brands, including Bianchi, back in the 80s.
tmar seems to be a member who knows a lot about the subject, amongst others, so I'm hoping someone out there will recognise some of the features on this frame, such as the cinelli style brake bridge or frame reinforcements, and be able to point me in the right direction.

May seem like junk but as you already noted, star shaped bottle bosses, forged RDO's albeit hacked, fronts too?

I think this is pretty cool having been aware of Hodaka mc's like bill, Combat Wombat, Dirt Squirt, etc.

What I didn't know was that they made any bikes of this quality, very cool.

We need more pics so you need more posts to show us the BB area, SP lug, HT, fork crown, FDO's and maybe scrub them off to look for stamping, rears as well.

Better pics from bill bring this into way better focus.

There's a lot of good work here, I would get this stripped all the way down, media blasting preferably, maybe powder coat or serious etching primer and paint supplier mixed spray can paint with clear coat and get this nice again.

Do we know if any of these were Hodaka branded at this time?

Paging @T-Mar

Thanks guys for your input so far. Nice to have confirmation that the features that caught my eye are indicators of quality
i have little experience of frames this new, so wasn't sure if it was just in my head!
I'm planning on media blasting it at work and then brazing the missing bits back on. There are a few dents, but nothing that looks too catastrophic, I'll probably just fill these with silver solder before jenolite (phosphoric acid) and respray. Finding some suitable forks at a suitable (read as close to free as possible) price might take a while though! Plenty of time to figure out what colour to paint it😀

A bit more cleaning up of this frame shows what I'm guessing is an investment cast seat lug, and what looks like a makers mark and 'G3' stamped under the top head tube lug. I've found an example that looks much the same in this thread:
Mystery Road Bike
unfortunately it's another mystery bike thread




im probably clutching at straws here - I've trawled through the web and found examples with individual features that match (such as the G3 mark) - but they all seem to have more differences than similarities. The concave tops to the seat stays tally well with some Miyata frames, which could also tick a Taiwan box - but then I can't find any Miyata's with similar brake bridge or reinforcement. And so on.
thing is, it probably doesn't really matter what it is / was - it's just bugging me. I'm like a dog with a bone when it comes to these things!

Your concave tops on the seatstay were fabricated, not pre made inserts. Sign of good workmanship again.

Interesting. We had a couple of Hodaka motorcycles back in the early-mid 1970s. Back then they were considered a step up from mini-bikes, but not "real" motorcycles. Good for smaller teens age 12-15 to get the hang of a dirt bike before moving to a "real" motocross, enduro, trials, etc., bike. I moved on to a Bultaco 250 flat track bike but never really got the hang of it. Too much bike for me at that age. After awhile I got tired of rebuilding the engine every few weeks. TBH, my little brother and his friend had more fun on their Hodakas, which just kept chugging along faithfully.

Never knew they sold bicycles. My first guess would be decent but unspectacular hi-ten frames, given the price range of most Hodaka stuff.

Concave caps are pretty distinctive - closest other example is this 'Italian nishiki' here
Italian Nishiki?!? What did I just buy?!?
the main differences seem to be in the bottom bracket shell and head tube lugs. Bridges, seat lug, caps, dropouts and stays look much the same.

The symbol before G3 is the brandmark of the Asian-made lugs, I always think "Eisho" when I see this mark but am fully prepared (and expecting) to be wrong. T-Mar is sure to know.

Thanks for info Unworthy1 - I was kinda hoping someone out there would be able to ID the mark - I assumed it was Asian in origin, but having a possible manufacturer name to follow up is great. I don't suppose you have a list of companies that tended to use these lugs do you?!

No, 'fraid not and it would be a very long list, this was a popular lugs/bits supplier.
Don't think it was Long Shen but I keep drawing a blank, I know T-Mar has correctly IDed this make more than once but I can't get it to lodge in my braincells.

I reckon you're under estimating your braincells, Unworthy1 - I found another thread in which T-mar IDs the lugs as Eisho Seisakusho.
so that tip has got me looking at Lotus and other bicycles made by Tsunoda - these seem to be getting pretty close - though can't quite match exact model - the quest continues
