Soapy water is your friend with the leak down test. RH crank seal failure will add pressure to the trans which will exit through the vent below the carb. Again, soapy water can help you track down where the leaks are,

After checking historic forum posts, I think I got enough education to proceed. Yes, I'm going to put two cooling holes in the front of the piston, too.

What are the tools involved and the procedure for relieving the exhaust port bridge on an over bored Road Toad cylinder? Does the piston benefit from special treatment?

This whole scenario reminds us of the old maxim of the 'known good' method of solving mechanical issues. A time honored trick for isolating problems.

If the cam lobe in the flywheel is not very smooth it will wear down the rubbing block on the points until the points will not open. Polish and lightly lube the cam lobe. I've never seen points fail in the way you have shown, but we learn something new every day.

What a great story, Clarence. I can relate to quite a bit of it.

If available, substitute another shift cover and compare. The old 'known good' test.

Will an HT 1 pipe work on my 03 Wombat? What are the plusses and negatives?

A Resonator Revisited article shows how to make an effective 'buzz box'. I use that but also use a cellophane strip between the points with light pressure which will slip out as the points open.

Let us know what it is when you figure it out....

Maybe Tim Nunn. 253-797-5831. I've had good luck with him.

I have a 'paper weight' mikuni. Surely most of the parts must be useable?

Not sure about ducks but the rubber chickens I have known are yellow..

Which Hodakas, if any, came with no steering head badge.

One of the very few things I disliked about racing the Combat Wombat was the close ratio difference between 4th & 5th. A bit 'longer legs' in cross country races would have been nice.

I've used electrolysis, chemicals and agitation. I usually prefer mechanical shaking with pea gravel and water with frequent rinses, then vinegar to get out last rust. Rinse and quick drying followed immediately with gas/oil coating. Use tank liners only as a last resort.

Weren't the Road Toad cylinders all black?

I have a 100cc unpainted cylinder with, bridged exhaust plus reed and oil injection intake. Whatzit for??

I once worked on a Kawasaki with rotary valve that someone else had put together. The oil injection feeds into the intake between carb and engine. The vent hose to the carb and the oil injection hoses had been crossed. The straight air into the intake downwind caused an ultra lean situation and the ...

I recently bought a Dirt Squirt from Tom Rapp who got it from Jim Pomeroy at Hodaka Days lang ago. The bike has a Webco head with a Rat like compression profile. A standard Ace piston is used but two head gasket raised the head a bit. I assume this was to lower compression/clear the piston crown. An...

I'm thinkin' it's about his super hot Ace 90. I'm looking forward to more!

Depends on if you include the side covers, shifter mechanism, etc.

Because of the domed top of the Ace piston, it will hit the Rat head I believe. Clearance issue.

I recently ran into a 100 with a Rat head over an Ace piston with two head gaskets to gain top end clearance. I assume the compression would be quite high and the Rat squish profile would be beneficial. This was on a bike owned by a prominent racer. Does anyone have any observations, theory or exper...
