Greetings:

With the State Safety Inspection SCHEDULED (Darned CoViD!) for Friday, I had some time on my hands to perform maintenance on ISO, now with 545 miles on its odometer. The mileage appears to be actual, based on the general appearance of the scooter and Vintage 2004 Pirellis.

I decided to tackle the oil change first. Lots of online hints - park with one centerstand leg in the drain bucket, plastic bag around the stand - led me to omit exhaust removal. I don't want to compromise my inspection date by fouling up something else... exhaust stud?

Oil filter blocks the plug from the front, so Eased it off with trusty channel-locks without issues. The PLUG: No need for a 24mm box-end. Good ol' Craftsman 15/16 box-end from the Carter administration fits like a glove. Plus mine is like 16 inches long, so little effort to coax it lefty-loosey. The oil screen had more gunk than I expected at this mileage, and I found why;

Attention turned to the airbox. New Malossi filter ready, I readied to remove the old one and found... NONE! Just a few brownish clumps of gunk adhering to the airbox walls. I have seen polyurthane foam deteriorate and become crumbly in a previous (Honda) scooter. In the case of 2-strokes, it'll catch in a reed valve and stall the engine entirely. In this case, the engine appears to have inhaled the entire thing over time, with the residues caught in the oil screen and filter. Glad I changed the fluids!

Color-rite pen addressed the numerous storage dings and nicks. The scooter Was good-looking from 10 feet away, Now pretty good from 5 feet distance.

Good you chose to do a tune up. Poor scooter had a ruff 500 miles.

I agree! I forgot to mention that I drained and bled the 17 year-old, dark brown brake fluid too. Innumerable other small tasks to address functional and cosmetic issues. Got some matching pain from Color-Rite for numerous shed scratches. Right now searching for the location of the secondary air filter?

Are you referring to the SAS or secondary air supply, this has no filter. It is a charcoal canister and a rollover bulb. There is no second filter.

Greetings:

I had just now come to the same conclusion after pulling various sundry parts. Thank you for confirming my suspicions. The parts store still sold me one, I wonder if it belongs to a different scooter. I am about to pull the kickstarter for evaluation.

The kickstarter on the scooters are pretty terrible. Would only recommend using them in a pinch. The aluminum case likes to crack if you kick them on any angle too rough. Pretty simple setup it turns on a spline and has a return spring for the kick-start. With the cover off you can easily move it by hand and see that the spline comes out to engage your variator and if it returns back your Springs working properly. Also a note on your SAS they were for the American market and there are threads on how to remove them. It is unnecessary for the bike to run properly. This involves removal of your charcoal canister and the rollover bulb. And plugging the lines that go into your intake after your carburetor.

Greetings:

Thank you Orange. I did manage to correct the rounded-off castles on the spindle and crank. Reinstalling the tricky return spring was quite the challenge! I have Kick-Started ISO a half-dozen times, treating it like walking on eggshells. I will heed your advice to use it only when necessary, but I really like the fact that it almost always starts up with a single firm kick!

New Michelins from the current decade are on the way.

Next up is a #12 battery. The P.O. installed a #14 that seems to be a bit low on voltage even charged up with my Smart Charger. The 14 is too tall to install the battery cover. This just won't Do.

When you go to the Powersports store get an AGM commonly referred to as a glass mat battery opposed to a standard VRLA battery. The valve regulated lead acid battery is what you usually find in tractors and such. Most of them you add the electrolyte to and then seal them off. Problem being these batteries usually only last 2 years and they're not as powerful as an AGM battery. An AGM will retain it's charged for months without a charge being added to it. And despite popular opinion batteries discharge faster when the weather is warmer than when cold. You lose a lot of cranking amps when batteries are cold but they hold their charge longer due to electrons moving slower inside the battery. So a valve regulated lead acid battery will run you $60 or an AGM will run you about $110. Get the AGM it also does not vent sulfuric acid like standard liquid-filled once do.

I also capped the kick-start on my transfer case. My transfer case I painted black to keep with the orange and black themed and the aluminum Kickstarter breaks up all the black from the wheels and rims and the transfer case up nicely. I've never had to use it but it is nice to look at.

They added the SAS in 2005, I think The early Leader engines don't have it. The invisible air cleaner is fairly common with older Vespas. You might want to check that new air filter, because Malossi doesn't make one for the ET4. If it's for the ET2, it won't work.
