The magnet and alloy cup inside speedo are either distorted or corroded.
 The return spring may also be broken?
Only way to find out is dismantle it


Woohoo! dismantling things is fun.


These things are so awesome. Can't wait to see where you go with it.

going to be as close to original as possible.


One thing throwing me off is that it should have provisions for winkers (turn signals), seeing as how the frame has mounts in the rear and the front has the winkers mounted (though haven't checked if they are currently wired)... However, no turn signal relay to be found or turn signal switch on right hand grip.


Sold some computer monitors I had found in the trash a while ago and spent the money on some side covers, turn signal set, cush drive for the rear (NOS at a good price and I figured they should be replaced while I'm in there), air filter with a new housing, and a battery latch as the old one had rusted through and broken.




Total Money into this so far, Including shipping Costs: 
BIKE:    $325.00
PARTS:  $99.73

Theres a couple hundred dollars worth of parts that she'll need to be perfect, but I'm trying to save where I can...

The following parts will seriously eat into the cost of this project, but are fundamental to having the bike be in top condition:

New Exhaust: $80 + $60 shipping. If anyone has one laying around thats mint, or a way that I can close the tiny little hole in mine and then re-chrome that bit for less than this price, please let me know as i'd like to save as much as possible on this restoration while still keeping it top notch.

Rear shocks: $36 + $35 shipping. Surely, there has to be a way to rebuild these for less? I have yet to pull them apart to take a closer look.

Seat: $36 + $55 shipping. Anyone have one thats not torn at the rear and preferably white? Or has anyone tried the covers on ebay, and have a good review on them? they are a lot cheaper at less than 30 dollars, shipping included.

rear shocks, pull down top cover, loosen  lock nut, unscrew top - easy peasy  ;D
 bite the bullet on exhaust, they are real thin tin and real hard to weld up

Don't make the same mistake twice - get this thing running and evaluate the motor BEFORE you either spend more money on it or turn it into a pile of parts.

I've learned my lesson. The 350 was running great and was perfect; it's my ambition which made it into such a huge project. This has not ran yet, but there is no physical reason why it won't. It has compression, it has spark, and soon as I get a fuel line it should have fuel. worst case scenario I'll need to rebuild the carb to get it going, and I expect a seal or two to spring a leak so I have a gasket set on standby if it needs it. I'm going to get it running perfectly mechanically bit by bit (starting with the major issues first and knocking out the glitches one by one), and then once that is all set I'll tear it down and send it off for paint in one shot. not much is needed to take this down to its frame so it should be a quick enough process at that point.

good tip on the exhaust... I figured that would be the case. as for the rear shocks, I could have guessed that much, but was not sure what parts I would need to successfully rebuild them.  seems there are some bushings on the top and bottom? should I attempt to drill and tap a hole in order to swap the damper oil out?

Until you have it running you won't know if it has a blown crank or something else wrong with it.
 
Assuming it will run because it appears to have compression and spark is still an assumption.

BUT I SAW YOU DO IT IN YOUR THREAD AND I WANT TO BE JUST LIKE YOU! haha... fine, fine, I won't... just figure I eventually need to learn how to make non-rebuildable shocks into... rebuildable shocks... :)

yes, very true... but it supposedly ran right up until it was stored, and only has 5000 miles, and the oil was still clean among other things, so i'd be super surprised if it doesn't run. Heck, even the brakes are fairly well adjusted and the throttle cable isn't too gummed up either.These bikes are bulletproof... heck, they were designed to be from its conception in the 50's. However, it is possible that it had its neck wringed for every one of those 5000 miles, so I will continue to hope for the best but plan for the worst. Luckily, parts are relatively cheap.

Everything thing you've said is an assumption.
 
Even if the bike was in pristine condition when it was parked.....it HAS been parked for many years. That alone can ruin an engine even if everything else tells you it should be OK.
 
Get it running first. Shouldn't be hard (a quick carb clean and some new fuel hose) and at least then you'll know if you have a great project or a parts bike.

Shocks I drilled are rebuildable ones.
 The dampers on C100 are 'swaged' and not rebuildable
C100 is pushrod motor so the new OHC stuff doesn't fit.
Hillsy, if it's over revved, the pushrods jump out of tappet blocks and bend (been blowing them up since I was 11~12)
Pretty sure it has a 'dipper' on big end but it's been around 42 yrs since I was inside one

Tomorrow, after I adjust valve lash and points, I'll pump some fuel into her and see what happens. Finally got another tri-pod since my last one broke, so I will also take some video while I am at it.

Hillsy, believe me I know what you're saying and do not deny any of it. Although the bike has been parked for many years, it has always been used as a centerpiece in a big room and has been well maintained (as in moved around once in a while and kept decently clean), except for being molested by an art student with a paint brush a few years ago. The chances of there being any major damage to the engine are really slim. For the record, nothing in my previous post was an assumption... Believe it or not, I actually know a thing or two about motorcycles and these bikes. also, my father grew up riding a honda 70 and knows this bike inside and out considering how similar they are.

PJ, I know that it's a pushrod motor and that OHC stuff doesn't fit. Most of the parts are repro's made in Japan or Taiwan, and sold through retailers in taiwan to the US for relatively fair prices, as long as you buy in bulk and save on shipping.

From what the previous owner told me, I am the third owner. The original owner was an older guy who passed away in the mid to late 80s, and the bike was then sold, sans any papers, by his granddaughter to the guy I purchased it from. I'm willing to trust the story, seeing as how the P.O. has been very honest with me and cared more about seeing the bike go to a good home rather than getting as much money as he could out of the deal. Seeing as how most older guys don't care too much for beating the heck out of their nice motorcycles, it should be in good shape. That is, of course, that the older guy doesn't go by the name of crazypj :) .

This is enough speculation though... as they say, the proof is in the pudding. Knock on wood it's all solid and won't need a new motor.
