Hmmmm, just for kicks (and to assure that assumptions don't jump up and bite you someplace again), how about measuring the minor diameter and major diameter of the splines on the actual countershaft? It would be a bummer to source a new sprocket with a 21mm inner diameter and find that the countersh...

So I did some "back of the napkin" calculations . . . and those non-OEM sprockets result in a 25% reduction in the contact area between the contact faces of the countershaft splines and the contact faces of the countershaft sprocket splines. That is obviously not good for long term reliabi...

Looks homemade to me. Reasonably well made - but homemade.

My first and second motorcycles were Hondas. So the Poweroll information is sort of interesting. But you do know this is a Hodaka page right? We'd be more interested in information about your Hodaka.
Ed

I second the idea of at least doing a bit of searching for the period correct reed valve unit. Who knows you might just find one!

I really quite like the Duro tire on the rear of my Combat Wombat (18" tire), but I haven't ridden one of their 17" rears. It seems to me that the body of the Duro tire isn't as stiff/rigid as the Cheng-Shin . . . and I like that. Better "gription" and "feel" in the wet...

Awwlllriiiight! While I was coming up with (yet unspoken) crackpot ideas on how to "fix" Darrel's problem, y'all may have hit upon the cause of the problem! When Darrel gets to the point that he can talk about this situation, it would be good to get some accurate dimensions regarding the d...

Well dang! That IS depressing! When you get to the point that you can talk about it . . . It seems like we are seeing only two data points on these shearing failures - "New" . . . and "toast". Have there been any "mid-life" inspections which show things are starting to ...

I've never opened up that model of pipe, but I don't think there is any baffling in the pipe body. After a proper pipe barbecue I like to do some pretty aggressive rubber hammer whacking on the pipe to dislodge any carbon build-up which might still be stuck inside. Finally, have you followed the pub...

Thanks Clarence for that overview of your time with the Forest Service and touching on your time as a Hodaka Dealer! As a fellow retired person, I took the most value from your parting comments for us ol' coots - which went something like this: "If you don't know what to do . . . do something.&...

I don't know about the SC transmission ratios "wearing you out" -- but from an old endurance racer viewpoint, I kind of find the first, second, third, third, third ratio spread to be kind of frustrating. (But I guess true MX racers like that.)

Ed

Clarence,

I'm guessing you tried to attach a video clip to the message, but it didn't "take". Might want to check with Dale for advice on what to do.

I can only offer up teensy bits of info right now, since I'm off to the wilds of Idaho with my smartphone and I'm borrowing a Starlink connection to the world. The easy to type stuff is suspension - Progressives (14.5") at the rear, forks/triple clamps from Wombat 03 (stock, I've ridden 03 fork...

. . . just so you know my true colors - option 5 borders on being blasphemous to me.
Ed

PS: Running reeds in AHRMA 125 Class will put you with the fast guys.

Option 2. (Engine is a "bolt in" swap.) You'll have some details to work out with larger carb and air cleaner connection. Exhaust system you choose will also have a MAJOR effect.
Ed

Here is a little bit of additional information which may be helpful to the Hodaka tribe. The factory cylinder heads for ALL alloy cylinder 100's and 125's are exactly the same on the OUTSIDE. But the combustion chamber and squish band size/shape/volume varies to match the engine(s) they were meant t...

Different combustion chamber shape and volume - and squish band.

I only have about twelve miles in the saddle of the Hodaka 175 (lifetime total), so I can't provide an authoritative rider report. However, I can report that my first impressions included . . . nice feel to suspension, . . . wayeeeee more nimble handling than any of the other "Big bore" Ho...

PS: It would be easy to misinterpret my previous message. I meant modifications to the supplied molded fenders . . . with the modifications being done at the factory in Japan. (But I don't know.)
Ed

I don't know whether modifications were made during the molding process . . . or after molding at the factory in Japan. Sorry, I just don't know.
Ed

Nope. Sorry, I don't have a clue.
Ed

. . . and I pretty much lean the direction tether is going. The toaster tank Dirt Squirt is a mighty fun little bike to ride with the stock size tires. I just finished the Bad Rock Trail ride on one a little over a week ago. Yes, tire selection can be problematic -- but handleable. And a Dirt Squirt...

Why?
Ed

I vaguely remember seeing a center case gasket for Hodaka back in the day in the Service Department at PABATCO. But it is clear that A) a center case gasket is not needed and B) never became a staple of Hodaka engine rebuilds. The gasket I remember was er, um, "paper thin" :roll: - kinda l...
