this may be a dumb question. is it a good idea to remove caked on grease and dirt from an older scoot's engine, forks etc?

all i know is when i had my 66volvo p1800's engine steam cleaned (i was very young so cut me some slack) it opened a whole box of worms.

Should be OK. Some degreaser and a little gentle scrubbing perhaps? A good time to check your cables and what-not. I don't think there's much chance of doing damage, as long as you keep water away from the electricals.

Keep the water away from the Air filter and carb. A lot of the rubber grommets are missing off the back of the airbox where the mixing screw is. Personally I just use a plastic scraper for the thick stuff, then some shop paper towels with some simple green once in a while after that.

Its time to get up close and personnel with your Vespa... Put down a big piece of cardboard get some rags a small plastic brush and, a big spray can of Engine De- Gunk found at any auto store.
Take your time and let it soak in. Try not to get any on the rubber bits. If you do rise them off right away with warm water .In fact after your done with the whole DE-Gunk, wash all the surfaces you cleaned with warm water.
This is also a great time to check that all your screws are tight, or need to be replaced. All the rubber plugs are found at Scooter works for just about nothing . They are there for a reason...

I spent a lot of time this winter doing all I could and I'm just about done ..........Take Your Time And Enjoy...

The best degreaser I've found is called Ecotech2 by Finishline products. I get it at the bicycle shop. It is a soy based degreaser, which is biodegradable and nice to the castings. If you got caked up gunk, scrape as much off as possible with a plastic scrapper. It helps to block the scooter up and remove the rear wheel so you can get at the back side of the engine. I use a tooth brush to scrub the degreaser into the remaining deposits and loosen them. If you use the traditional brass spray nozzle on your garden hose, you can open it up just enough to get a light fan spray and rinse the degreaser without penetrating things like the airbox and clutch cover vent , flywheel,ect..
You may need to repeat once dry to get it really clean. Then use the degreaser annually, or as needed so the cake doesn't have a chance to build up.

Oh, and you want the pour bottle. The spray, while convienient, goes too fast. This stuff is like $10-12 a bottle, but worth it in my opinion.

i dont have much more to add.

it is nice to take pics of before and after.

i find it to be insperational.

caution: when spraying and de greasing becarefull not to get any residue in the area between the rear hub and rearhub plate. you will get grease residue in your drum and you will have to remove wheel and clean drum and pads.(which is not a bad thing,just another project)
