Was the key you found by chance a wombat or ACE 100 B key? A square key?

Ladies and gentlemen. Toaster oven. Toasted it 3 to 4 times for a few minutes and gently worked at it with a paper clip. Well i broke the top ring. But the bottom is good! So, when in doubt, have a toast!

Thanks for the reply. Key can't fit the slot. The ribbed channel on the key slot is on the opposite side that this key's is on. The key hole/slot has a flat side (left) and a channeled side (right) the tumblers are on the lower position (nearest edge of barrel) and all are flexible and functioning. ...

OK, my new Hodaka Ace 100 key does not fit the key hole. Notice the keyhole has a notch on the side of the key that is smooth. What could have happened here? I will have to take this switch out and take it to a lock smith. The keyhole is clear, no broken key in there. Scratching head. Is it possible...

These pictures are great. Nice work to visually lay it out. Now i see what is going on. Is there a grease one can use to help seal as well as last a while with the gas? Or perhaps that is counterintuitive to the soft metal design. :-0

did you post images?

Perfect. thanks

Sounds good. Will try a heat gun on low setting. I assume its ok to use a wrench on the nut to do the turning (?).

Guys, on my 69 Ace 100 tank I have the brass petcocks the right side opens, weeps a tad bit. The reserve side is completely stuck in the off position. The tank has been sloshed with what looks like Red-Kote (its red and rubbery). Before I go twisting things about, I need to know how these operate. I...

The Hodaka Ace 90 Wiring Diagram is exactly the way my bike is wired. Bravo.

Thanks Roger, I just saw this. For some reason I'm not getting notified of updates to the forum. This info may dispel all the mystery. And i was just about to rewire the bike! I can find the Ace 90 wire diagram I think. I'll have a look and then see if there are any changes I should make. I would li...

How'd you loosen the ring with the piston out? I've used Vinegar, ATF 50% with acetone, Penetrating oil, Napa Carb dunk cleaner (the newer eco stuff), metal rescue. Nothing is breaking this crud buildup on the rings. Piston looks pretty good as does the bore so my thinking if these springs can open ...

should i just take the head off and will there be any way to tell? Or will I need to remove the whole barrel? Also will I need new copper gaskets after that? Waiting for the manual to arrive but want to get a jump on this.. Can you soak the piston from the top through the plug hole to help loosen th...

Thanks to all who are helping me sort out this non running Ace 100. Figured I'd start a new thread based on "getting it started" UPDATE: Unplugged the black wire from the ignition. So just running on direct to coil. Coil is producing spark. Checked with meter (approx 5.5 or so) and can see...

Thanks guys,
I managed to get that lever all apart. The spring was fine, just bent and not connected to the lever at all. Awesome!. After an hour of wrestling with the slippery cup I managed to get it on there and get the alignment and rubber stand-off all back together. thanks!

what should the plug gap be?
Oops looked it up. .024

The blue and black wire should be "connected" only to the coil?
Sorry

Including a wire diagram here

Thanks guys OK So 2 scenarios Leave the ignition bolted on: !) Unplug Black wire only (preferably with a Connector back to "ground" AKA Kill Switch) 2) Disconnect all the wires from the switch "except" the Blue and Black wires It seems like the illustration shows only 1 wire for ...

Hi group. Another pre weekend post! As some have you have seen, I've been trying to get this Ace 100 started, just to hear it run, before I sink a ton of money in it. I bought it not running and just realized the return spring on the kick is not functioning. How hard is this spring to get to? And is...

I took the ignition away from the frame. Maybe the ignition is supposed to stay grounded while kickstarting? (duh!) There is no connector block that I can see. Maybe a spliced wire job here. And the loose blue wire near the switch was wedged to the frame, I assume touching the bolt in order to creat...

That spec sheet is great!

Starting a new thread about the "No Start" issue.

I bought the bike not running. Thanks for the oil to gas ration. 3.2 oz per gallon it seems. I will need to drain the oils and grease the shifter on the magneto side, since I had to replace the cover and shift element. What lubes and oil procedures do you guys recommend, along with capacities? I've ...

what weight and brand guys?
And capacities

Hi guys, The only stupid question is the one you don't ask. This newly acquired Hodaka Ace has fuel in the tank already. Sort of a bluish color so I assume it has been pre-mixed. Smells ok :-) What is the 2 stroke mix ratio running supreme soCal gas? I usually opt for Chevron around here. Anyone got...

Thanks guys, I didn't receive your replies even after logging in. Maybe I need to adjust my settings. What a cool group. And thanks for the advice! Re: Key, maybe I can start with a blank but it is stamped 3121 on the outer sleeve. Perhaps that is a tumbler setting (oof, this tape will self destruct...
