New Member/Trouble identifying a 1970 Model

[AdamY_61]

Hi guys. New member here from Kentucky.

My family has a long history with Hodaka motorcycles. My grandfather had a dealership here back in the day partnered with a good friend of his.

I have a bike that I'm having trouble identifying. Every chart I have looked at, the # on the frame doesn't seem to match up on the starting or ending numbers.

Production date on the steering stem tag says June 1970. Frame # A-44112. Engine # EH 13908. Best I can tell is the frame is an Ace 100 of some sort, with a factory replacement Wombat engine of some kind?

Any help is greatly appreciated. Can't wait to start restoring it!

Thanks,
Adam

Looks like a 92B frame, so Ace100B and EH does represent replacement Wombat engine. Post up a photo of the bike.

Everything I have, lists a 92B starting with 51013. Blue books lists the 92B coming out in 1971. ------- Clarence

You have a 1970 ACE 100B. The Engine is a replacement for the Model 94 and Model 94A 125 Wombat. I have one Frame #A44174. The Factory engine is still in it and is P44151. That chart needs work! If you want to put the correct engine back in it parts are plentiful. Ace 100B is the model Name. The Model Number is 92B. Some charts show 92A but I`ve been told that`s wrong. Cases are plentiful. Anything in the P40000 range will get you back 100% correct in the Engine department. Any Boo Boo that I have made will be corrected by someone else in this site. Model Designations still Puzzle me a itsy bitsy teenie weenie bit. Joe

Others show A51013 as a B+. Joe

My list shows #51013 is the start of the 92B+

These parts items are also found in my hodaka price lists. My brochures also show model numbers and print dates.
You do have the ace100B but it is not a model 92B so there was three different models to the 100B and that leads to confusion. Clarence

So does this mean it's a transition year? It has the high clearence front fender if that's of an importance. Apparently 1970 was a confusing year lol. I'll try and snap some photos of it this weekend for you guys. I appreciate all the help!

The articles in the Magazines and the Sales Brochures were different.There were misprints in every Magazine.I have the (1972 Motorcycle Buyers Guide).In it there is a Photo of the Super Rat and the trail model they call a (100B). The problem is that you can see from the frames that they are 1971 models. The frame bracket for the Swing Arm is a little longer in 1972. Positively 1971 models listed as 1972. Just tell everyone you have a 1970 Hodaka Ace 100B and that`s about as correct as you can get!

[taber hodaka]

Hodaka never saved up all the changer for the next model, they just kept upgrading, improving parts and put any changes into production immediately. So yes some upgrades were incorporated before the next model number was determined. It was easier when when lived and worked through the hodaka era as a dealer. You have a great bike there that you will enjoy. Clarence I just see Joe"s comment and he is spot on

[AdamY_61]

Thanks for are the help fellows. At least now I know what schematics I need to be looking at for parts. Appreciate it!

[Joe Ormonde]

The hardest thing to find out is what M Code or P Code for the Model year. That`s why I posted my Serial Numbers for you. As you can see our Hodakas have really close Frame Serial numbers and the engine is the Factory one. That bike belonged to Greg Zitterkopf. ATK Top Pro! Some of the fastest Desert Racers ever started out on a Hodaka !!! Joe.

I think that's pretty cool how close they are in numbers. I appreciate the info!

[AdamY_61]

Here's a couple pics for you guys. She's not pretty by no means. But it spins over freely and most of the parts are there.

Interesting! Not a recognizable exhaust, though it’s missing the heat shield. A Model 94 Wombat airbox, a Super Rat chain guard, and a B+ front fender & Mount, or similar!

[matt glascock]

That looks like it might be a Hooker expansion chamber. If so, cool. I have not seen one for ages, but a lot of guys I lined up with back in the day considered them a good performance pipe. I always liked Torque Engineering pipes better. Smaller and easier to tuck in.

[taber hodaka]

Looking good! The high fender is bolted up without the bracket something we would do in the day, the high fender was introduced January 1 1971 on the 92B. Modified, reinforced, and extended rear swing arm must have been a serious rider. Rear sprocket was used beyond normal use. Really nice that it turns over, you will have fun.-------------Clarence

[AdamY_61]

I believe it is a Hooker expansion chamber. I'd say chances of finding a heat shield are rare, but I wish I could.

I'm glad someone pointed out the swingarm. I never noticed it until yesterday afternoon. When my grandfather had the dealership my uncles raced MX. Only thing i can figure, is they gusseted it for the track.

[matt glascock]

Just a thought on your pipe. Hodaka Dave converted a Torque low pipe (without a heat shield) to an up pipe (needing a heat shield). He formed a blister of of heavy gauge steel lath and welded it on for an excellent, light, and effective heat shield. I've also seen ones formed out of sheet aluminum for bolt-on attachment if the mounting bungs on your pipe are usable. That's a really cool pipe. I hope you can restore it.

Very cool bike Adam. If you bring it back to life I bet it will be a really fun woods bike set up as it is.

I was able to get the broken bolts out of the heat shield mounting bungs. I have some thinner gauge aluminum sheets....I think I may try and build my own heat shield. It does have one small crack on the inside (think it was vibrating against the frame)....I'm going to try and stitch it up. I'm going to do everything I can to salvage it.

I think it would be too. I plan to keep the Wombat engine in it. And it will definitely be hitting the woods!

[matt glascock]

Cool Adam! I'm glad the pipe is salvageable. Its been a long time since I've seen one of those Hooker pipes but they definitely were a hot set-up item in the 70's. Probably few survivors. The aluminum makes an easy to work, effective and durable shield. That's going to be a really sweet bike. I'm really looking forward to watching the progress.

It needs a little weld and surfacing, but I think i can do it. I'm not 100% sure it was made for a Hodaka....Ace or Wombat...but I'm going to make it work lol. I'm in the process of trying to get the rust neutralized with vinegar in between sandings. Then I'll weld it up and resurface it. More than likely, after it's done and I ride it the first time, I'll probably gift it to my dad.

[viclioce]

Adam. Try some Loctite Naval Jelly for rust removal. And it works great on exhaust pipes. Brush it on, let it sit, rinse it off, repeat!
