Your pictures are too small to make out much detail, but it certainly looks like a model 94 Wombat cylinder. In the last picture I cannot see any holes to complete the reed modification. The 94 was not reeded from the factory, but it was a popular modification back in the day. I should also mention ...

Quite the dogs breakfast you have. You will need a piston with holes to take advantage of the reed setup. If the cylinder has been modified to run with a SC or CW head, the exhaust port will have been raised. I don't know of a two ring piston that will work in your motor unless you want to add holes...

Brian, What were the results of your swap? Was it worth the effort in performance and or reliability? I have all the parts and have been considering whether or not to try it. Hard to say. At the time I was looking for more power and less plug fouling on my Combat Wombat, but I made a reed valve con...

I have used an early CR125 ignition on a Combat Wombat and since the Toad uses essentially the same ignition as the CW it will work but there are a couple of problems you will encounter. The first is that the rotor keyway is in the wrong position. I used a dial indicator to set it up the timing and ...

The pat number you are quoting is an Ace 100 lighting coil, which is the same as the chrome tank Dirt Squirt lighting coil. This part will not fit your DS80. Your DS80 should have a lighting coil, and as Dan has already stated, should be the same as the Road Toad. The Dirt Squirt lighting could be m...

Good video. Early model Hodaka (chrome) forks all look alike but there were many changes over the years. The early forks with the larger top nuts were very fragile and bent easily. I have heard several first hand accounts of bent forks from people racing first model Super Rats.

This goes back a few years, but it's been a while since I have created a thread. Shameless post of me on an Ace 100 with stock motor and suspension up against a few BSAs. I stripped off the lights, put knobby tires on it, and had some fun. Can the Ace 100 beat the BSAs? https://www.youtube.com/watch...

Nice! I'm envious. I've been looking for one of these for a few years now, but I've never seen one north of the border.

I'm seeing the same thing with the rear brakes on my Road Toad. The linings are too small diameter, but not to the extent you are seeing. I have tried two different drums with pretty much the same result; too much lever travel before the shoes make contact. I have tried some aftermarket grooved shoe...

From what I can see, you definitely have a Super Rat frame. The forks indicate it is an A or B. Someone has modified the swingarm to make it a little longer which was a common mod, and the shocks are not stock. The front wheel looks like it could be from a Road Toad. Curious to see what exhaust came...

I've been building up a parts stash for years. Today I bought a CW piston and control shaft assy I found listed on Kijiji. I also acquired the remains of a local dealers inventory. Having a good stash of parts means that if I see a rough Hodaka selling cheap, I will often have enough parts to bring ...

Before burning the pipe, try pulling the spark arrestor/silencer out and see if it helps. I'm not saying you won't need to burn the pipe, but it's a quicker way of seeing if the pipe is your problem.

Hello, if the counter shaft sprocket is flat both sides its a 420 chain type, and if its dished a little on one side its the 428 type. I thought the same thing, but looking through my stash of sprockets I found several dished 420 sprockets. I thought that maybe Hodaka dished the sprockets to keep t...

FYI, looking at DID chain specs, their 428 chains have the following pin lengths (width):

428D (standard) - 14.75mm
428HD (heavy duty) - 18.9MM
428VX (x-ring) - 20.65mm

I run o-ring chains on my '72 SR, both '73 CWs, both 94 Wombats and a 99 Road Toad. No issues. I have never tried one on the Ace 90 or 100s but they are fair weather bikes only. Interesting... I wonder if there are differences in the widths from manufacturer to manufacturer. What chain are you usin...

Not sure about the Toad, but on earlier models I have found that there is not enough clearance around the countershaft sprocket for an o-ring chain. They are a little wider and wear into the inner shifter cover.

If I remember correctly, the black wire needs to be connected to make spark. Connect the blue and black wires normally. The ignition switch works by shorting the black wire to ground in the "OFF" position, so unplugging the switch will allow the motor to run. The trouble is you will have n...

You don't need a battery to get spark. There are two wires going to the coil, black and blue. Black is ground and blue is coil primary. They are both connected via a two pole connector, so unless someone has modified the wiring you shouldn't be able to disconnect just one. Post a picture of the coil...

If you stripped the clutch nut there is a very good chance you damaged the pinion bushing. I think it's a safe bet that the new bushing will fix it.

Brian

Check the clutch pinion bushing. Sometimes the bushing gets distorted (squashed or end mushroomed), especially if the clutch nut is overtightened, and then it will not allow the clutch to spin freely on the bushing.

Same here Clarence, I like lots of lube when putting the engine together, but I remember back in the 80's some racers were installing the piston dry claiming it would break in faster.

Brian

Both the Combat Wombat and 92B+ have top out springs and should behave the same. Hodaka recommends 30 wt fork oil for these forks, but this weight fork oil is hard to come by these days. Most modern fork oils are in the 5-15 wt range but Bel-Ray still produces a 30 wt fork oil if you can find it. I ...

If the indent you are referring to is the ring around the combustion chamber on the cylinder head, no, there is no special head gasket that mates with this ring. All Hodaka 125s use the same aluminum gasket. Have you checked for leakage around the head gasket and spark plug? Some soapy water sprayed...

And one more thing, my Road Toad racer (Super Toad) is my favourite Hodaka.

Brian

In my opinion, the biggest weakness you will encounter when racing the Road Toad is the gearbox. I have broken third gear twice on mine, once in a motocross and once in a hare scramble. Strictly Hodaka used to sell improved cush drive rubbers that reportedly solved the problem but they are no longer...
