New here with an 87 Riva 80cc project

Post by Low_Teq »

Hi all.

I just registered here this morning after finding the forum and wanted to introduce myself/scooter. I've already found some great information on these forums before registering.

I bought my 87 Riva 80 last year in a barely running condition and the price reflected that. It looked complete besides a bit of damage.
The scooter would start easily but not idle or rev high enough to ride. After going through the carburetor I realized that somebody had their hands in this thing pretty deep. There were missing gaskets, the main jet was missing, vacuum lines in wrong places, etc. I made my own paper gaskets since they aren't available, and ordered a new main jet but still just didn't have any luck getting it right. The scooter eventually got moved to the back of the garage until a few weeks ago when I spent some time researching different carb options.

I found this carb to be a close enough match to my original to clamp into place. https://www.amazon.com/gp/product/B00ZZ ... UTF8&psc=1
I decided it was worth throwing another $20 at the scooter. The original carb is about 25mm outer diameter on the intake side vs. 23mm on the new one. So the carb fit easily with a pod filter after removing the stock air box. The throttle cable works perfectly with the carb after adjusting the nut on the cable. It did bog and lean out anywhere over 1/2 throttle so I drilled out the main jet until it ran smoothly up to wide open throttle. I think the #58 drill bit ended up being the magic number. I think it's getting to the top speed but have nothing to compare it to. It will hit about 40 MPH on flat roads and about 43MPH downhill (gentle hills, nothing steep around here)

After getting the scooter running well, I had a new love for it. I bought a battery, cleaned it up, installed LED bulbs in the turn signal housings, and I am going to try and find an undamaged fender. I have a new seat cover arriving in a few days. I will probably try and find the cleaner looking rear lights and turn signals that the US models lack.

Here's a few pictures of how the Riva sits as of this morning after a nice ride, and a picture of the Jog carburetor installed.

The new seat cover arrived yesterday afternoon. This was my first seat recovering attempt and it went pretty smooth.
I forgot to take any pictures of the progress. I'm happy with the quality of the new cover and for $30 I think it was big improvement to the scooter. :)

My wife and I went for a ride afterwards with me on the 85 Honda Aero80cc and my wife on the Riva. The Riva outran the Honda off the line and top speed every.single.time. I thought I read that the Rivas were slower and less power than the Hondas. Maybe the newer Carb with the main jet drilled out made some difference? Now I am getting bad ideas about what to do to the Honda to squeeze a little more speed out of it. :twisted:

Very nice work on the cover.
