Lets see a picture of the pistons sides. Could be as simple as worn rings. Low compression or air leaks will cause starting and operating problems. I dont believe the hole is anything to worry about. More info on symptoms before tear down will get you help and pointed in the right direction..

You should be able to find a right side case half pretty cheap. The left side case is often chain damaged an will be more to replace as clean undamaged ones are getting rare.

Those transfer ports are hogged pretty close to the cylinder liner. This area would have poor heat tolerance before deforming. This has been modified to the extreme and likely has no room for an overbore. I'm afraid you may end up with an interesting conversation piece on your shelf. But,,,they ainn...

Victor. You have to be the most dedicated champion of keeping the old brand running. My name is Brian and I used to be a frequent contributor to the tech section of the Hodaka newsletter. I started racing Hodies in 1970. We ran a 3 bike race team when my boys became old enough and earned 2 State Vin...

I think this situation jumped from an earlier post where the rebuilt engine would not spin fast enough with the kicker to start. Some carb issues got mixed in. Something was dragging and a second tear down was started. The right side crank bearing was suspect. We will have to wait for an update. Eve...

I believe the crank was stuck in the right side bearing.as he states he put the case half in a vise and used a plastic hammer on the crank to get it free. Now he is trying to remove the seal without damage to get to the bearing. No idea how clutch side of crank got stuck in a new bearing.

The C clip on the right side should not allow the bearing to be cocked. Since both left and right bearings are the same common bearing found at any parts store, you can cheaply replace both. Then try swapping the crank 180 degrees and fit it in the right case. Rotate it. Then try fitting the left ca...

No battery needed. The bike has a stater style ignition that provides spark and electrical current when the engines is spun over and running. Headlight and tail light can function without a battery but it acts as a current buffer in the system. If you plan on returning it to stock you gotta lot of p...

Diagram Q on the HPI website parts list show you the parts of the battery box and how that ties things together. That green cover is the battery cover. Its loose because the battery box is gone. The pipe can be mounted solidly without the battery box if you find all the parts. Since so many parts ha...

.Welcome to the asylum. Sounds like your biggest expense is going to be that low compression. You could get lucky and it may just be some stuck piston rings from sitting for years. Its hard to run an engine to that low of a compression reading by simply riding it. It would become difficult to start ...

300 is a best guess with you doing the tear down and reassembly. Budget 175.00 for top end rebuild kit which includes piston, rings and gaskets. Budget another 125.00 for machine shop services. This assumes this is ALL that's wrong. Since you cant hear it run, spark issues or dried seals, clutch or ...

Good piece of trouble shooting. Solve one problem, then move on to the next. Solve enough problems and you get to ride.

If you have been following the market for Hodakas they aint getting cheaper. Probably the original frame as the battery cover side plate would have nowhere to be mounted on an SR/SC frame. Looks like oil injection bypassed, wrong tail light, chrome rack, ignition switch and dash missing as are the v...

2 things are common. Crank bearings or transmission output bearing not seated properly or kickstart gear and mainstack not assembled correctly. Put a couple screws in and lightly tighten. Try turning the crank or rotate the output shaft. Something will bind and tell you where to look.

I just remembered to use these painted fenders on the 94 95 96 frames you need the later seat base with the longer rear mounting tabs for a no fiddle fit or the fender touches the seat bottom. I cant remember if you can modify the front lower mounting holes to compensate for the lower seat? I used t...

Will fit Model 99 and 02 Road Toad, Painted red it would be correct and work on an 03 Wombat or 01 Dirt squirt. Polished to its natural stainless finish should fit a Model 94 Wombat, and with some length trimmed off could be used on a Model 95CW or 96DS but would not be correct. Hodakas can be a lot...

Engine will bolt right in. You need a wombat exhaust but its direct fit. You may need a Wombat throttle cable and some fiddling with the air boot but i cant remember. The 125 for the makes a great transplant for the B+ which in my opinion is the best looking of the chrome tank bikes. That red frame ...

A lot of the guys trying to help are former dealers or Hodaka mechanics who are working from memory. Many of us are in our late 60s or 70s. I worked at a Hodaka dealership from 1971 to 1973. Those days are far from clear. We sold tons of reed kits, but this was seat of the pants racing with no inter...

2 statements in your first post still puzzle me and need priority. Not enough rotation with kick starter and no pop, bang or fire. Tried and true method of a squirt of gas in the plug hole and push starting in second gear may get you going. Once running jetting needs can be worked out.

I have test started engines without a carb by just squirting some carb cleaner into the intake manifold. Incorrect jetting should not keep it from at least firing. A new bore should not drag on the rotation of the engine during kick starting. Does it spin normal without a plug? A clutch side seal se...

I have used this method on some old spokes too. Silver paint does not have much base to protect metal, so you may want to add a light coat of clear to keep them looking good. Makes them wash up easier in the future.

Bikes cone up for sale on the hodaka facebook page every couple of days.

Also keep in mind that that the 03 uses a longer swing arm and longer shocks. Swapping just the forks could leave you with an unbalanced bike. I incorporated fork stops into the lower triple clamp of the 03 forks. They will dent the tank without some method of restricting side to side travel.

Another possibility is that since it died while running it seized and you were able to kick and push it once it cooled down. A quick seize will smear enough piston to stick the rings in the grooves and kill compression. Did it shut down at idle or while riding?

i hope the 51 psi of compression is a typo, This is way to low for an engine to run.
