Usually a moped guy, just purchased an Aero 125

replacement is in the mail no worries

Mail? You do know that any good motorcycle shop will stock these plugs?

[mikeosoft]

Yea unfortunately I guess i do not have "any good motorcycle shop" nearby me since every motorcycle shop nearby had neither Honda brand 2 stoke oil nor resistor ngk version. I didn't feel like settling for the wrong part so I used the internet and found out the local shops by me are horrible.

You need to check around, there will be a shop, usually not a name brand dealer, that will stock what the normal guy needs. I am lucky, as both my local shop, 12 miles away, and the nearest Honda dealer, 35 miles, know what customer service means.

Vee rubbers arrived today I am going to remove the rims and decide whether I should attempt mounting the rims myself with my Tyre irons or search for a shop that will mount them. Two shops I tried demanded they would only mount tyres purchased thru them.

Those two shops have no clue what "CUSTOMER SERVICE" means or how to get new customers. I would never patronize them.

It isn't all that hard.

nice link thank you, i was going to use this one:

But might reconsider for yours

I didn't read the wikispreedia page, but I will say this: the ADVrider method is a whole lot of trouble to undertake when you can just take the tire-irons and mount the tire in half the time it would take to just put all those straps on it. Certainly the strap method has an appropriate time to be used, and is quite innovative. But, when you ride ADV, your FIRST tools in the bag should be tire-irons. This is also a good example that "NOT everything you find on the internet is true or good."...learn how to do tire change the old-fashioned way...the ONE THING that will help you along with learning the method is this: Keep the tire bead pushed down into the center of the wheel on the opposite side from the tire-irons. This will allow the tire to have the necessary "slack" to fit over the wheel. Hope this is helpful and clearly stated. One more tip: NEVER try to mount tires in cold weather without first warming tire. The difficultly becomes compounded by a stiff, cold tire. Today would be a good day to mount tires here, high temp was 109...new record....

bear I ran into an issue. I was taking off the muffler to get the rear wheel off, when I took the muffler off, the rear swing arm assembly was lose around where the dust seal and more importantly the bearing from the rear axel i think, is missing. I don't know how long this has been missing, doesn't look like there is too much damage, the rear hub shows some wear around where the swing arm assembly rubbed against it over the years.

I want to make it clear that the swing arm was just loosely shaken free and not held on to the bolt where the main bolt goes through, as it should. It doesn't look recent, i think it's been ridden like this for ages. I'm amazed.

I did some searching, and I think I identified the parts I need, here's a pic:
I think I need 3 parts:
19
19
and 20

I am not sure which 20 i need


I might be totally wrong, but I can post pictures and even a video if necessary. I don't know where I can order these parts, but I will search the internet. If you can offer any advice, or possibly know if your dealer has these in stock, I would be forever grateful.

Both numbers update to the 6202U number. Available at you Honda dealer.

BEARING (6202U) 90912-KG8-004 $27.53

But your local bearing outlet store or even an auto parts store will have it under 6202U for one * of a lot less.

[motormike]

...wow... ...is all i can say, but get it fixed.
There are many other parts wearing out with missing bearings.

[mikeosoft]

I have ordered the parts i think i needed, thanks bear. I used some honda parts site online, and substituted the same 6202U off a CR125 for $5.35 (assuming the "6202u" is what is important). Also ordered the sleeve seal covers for the bearing. In the meantime I think I need to source a new swing arm off a doner bike or something because this swingarm needs to be welded back together on the exhaust extension on the back, where it ripped straight off.


Also, when i removed the muffler the unit weighs a TON. I think I recall reading one of you weighing your muffler pre and post cleaning with heat. Am I making this up or mixed up? I think there is some serious carbon build up in this muffler, in which case I need to burn it away.

[mikeosoft]

hey i got the tyres mounted, at first the bead wouldn't return, but I kept trying. I called a local kawasaki/suzuki shop because I noticed the 90degree angle stem on one of the hubs was rubber rotted and leaking if I moved it at all. The local bergan tire near me said they don't carry motorcycle 90 degree angle stems and to check with them. So I brought the bad bead/broken stem wheel over to them and 4 hours later they called me and told me to pickup my rim for $28. At this point I am just happy to have two mounted tyres on two rims with no more wheel issues. I just spent an hour cleaning and waxing the rims.

In the meantime I have purchased both the replacement bearing and both dust sleeves, but I also saw an feebay listing for a complete swing arm in better condition than mine with what looks like a fresh bearing and non-broken exhaust mount for $50 shipped. I thought about it and figured what the * can't hurt to have to at least compare with. Purchased that.

So far this bike is costing me more than I originally envisioned, but it's nothing new with hobbies for me. I thank you both for helping me with these repairs.

Weighed the muffler after taking it off:
10.2lbs

Weighed again post drano/firepit:
10.0lbs

.2 pounds = 3.2 ounces of carbon/rust/paint/anything else removed

Hey guys i went to walmart and bought up some chemicals to remove the carbon build up from the muffler.




Setup some sort of system in my backyard to hang the muffler to allow the drano to move around


About an hour in:


1.5 hours:


3 hours:


3.5 hours:


Once I was satisfied and the sun was fading, I hung the muffler overnight to drain after forcing water through the muffler for 20 minutes. Afer the muffler was done draining, I gave it a shake and noted some water left inside.

This morning around 8am I got up and lit a bonfire. I put the muffler in the fire for about 4 hours and flipped it every half hour noting that when i flipped it the side was glowing orange hot. About 30 minutes into this the remaining "drano/water" started bubbling out the exhaust manifold black like tar substance dripped and sizzled into the fire. Black smoke came out of the exhaust for about 2 hours of flipping around the unit.

I am going to weigh the tank in a few minutes after i use a wirebrush to remove the last rust and left over "surface charcoal" from the fire.


One question to bear or mike or both:

Do you use non-detergent 10w40 for final drive oil?

the honda service manual says final drive gear oil should be 10w40. I just am wondering whether or not detergent matters. I had some 30 weight oil once for a moped i worked on, that had a rubber clutch bushing that would swell if detergent was present. I am wondering if non-detergent is required or not, what do you use bear/mike? just honda 4stroke oil?

[motormike]

I use 10W40 motor oil. The only oil I'm familiar with being High Detergent is straight 30W marked HD. I'm not all that well-versed on oils chemistry....

Doing some research, I just fell here.
Interesting topic. So what is the weight of your exhaust after cleaning?

Some questions upon reading :
1┬░ I hear that the front brake cables are NLA. That is scary...is this only because of the few numbers sold in the USA?
An issue too here in Europe?
Is this an issue too for the Aero 50 owner I am?

2┬░ The belt is also a problem for the Aero 50? I saw one NOS over here, should I buy it "just in case"? What's the life duration of this belt usually?

3┬░ I couldn't find a fuel petcock for my Aero 50 : NLA said the dealer. I had a chance to find an aftermarket part that was ok. The chinese counterparts don't have the same threads...Honda Aero 50 is 14 x 100. Chinese is 14 x 125 and 14 x 150...
I understand your petcock is of a completely different design as you said you opened it? Mine can't be opened (see the topic in my signature below)...

4┬░ Do you have a link to where I could buy the small tacho you have pictured above?

Thanks for the input.
