    When it comes to tire I would try online to buy if your local shop has crap . I m guessing you might not get great mileage out of it. I would be more concern to watch how it acts in rain etc.

    I was going to buy a tire as well as tire spoons online so I can try installing it myself. But the aft tire picked up a wire and developed a slow leak.

    I had no choice but to get the tire from a local shop.

    I try avoid riding in rain/wet if it's possible.

    Changed engine oil. Used Synthetic Aeroshell 15W50 this time. I just happened to have it.

    I got a plug put in due to a flat. Is this a common practice to repair motorcycle tires?
    I did it because I didn't have other choice at the time. The plug seems to be holding up so far. But, I have new tire being shipped. It should come in soon.

    Can I apply a patch on inside of flat tire as a permanent repair?

    I have used plugs, and no issues so far. I haven't tried a patch. I buy tires online, mostly Kenda K413. Pirelli's wear out very fast.

    Pirelli lasted a little over 2200 miles in back. I am getting Kenda K329s this time.

    I haven't checked mileage since plug installation, but I had to add air once IIRC. I'll check the pressure again, before going home tonight.

    Other than the mileage on the Pirelli - did you like those tires? I need to get a set of tires for my Riva 125. I'm looking at either the Michelin S83, S1, or the these Pirelli's. All thoughts welcomed. Ride and handling are most important and I'm trying to stay away from anything made in China.

    Yes, I liked Pirellis.
    They were made in Brazil, not Italy as I originally thought they were from. But, I have no problem using these tires. :D I have long lost relatives live in Brazil.

    Most of my ride on Pirellis consist of dry paved roads. They gripped the roads well, good enough to scrape exhaust pipe (R) and center stand (L). Though it doesn't take much of banking angle to scrape. I had to hang-off for taking turns.

    For a little while, I had rear tire a little under inflated without knowing. Even with this condition, the rear tire never gave me surprise with sudden loss of control or unpredictable sensation.

    Now, I have a Kenda K329 in back. This tire is made in Taiwan. I chose this one for (hopefully) longevity.

    I have grate respect to people in/from Taiwan. I don't mind using Kenda Tires.

    I avoid using Shinko and Cheng shin. Don't ask me why.

    So, the tire came last week. And it is installed.

    [​IMG]

    Used this bead breaker.

    [​IMG]

    There was some rubber crud build up. So, I used nylon wheel to clean the rim. Also, I saw some corrosion pits. Sprayed anti-corrosion stuff on it, too.

    [​IMG]

    With some struggle, the tire was mounted on the rim. And the assembly was installed on the scoot.

    [​IMG]

    I worked in a bike shop many x2 years ago and had some experience replacing tires using a fixture for tire change.

    The tire change this time was all manual, all tire spoon and no fixture. Maybe it is due to the rim size, doing this time was a lot harder than I anticipated. :huh

    The shop where I buy tires installs them for free onto the wheel. I'm going to stop in and price these tires, Michelin S1, Michelin S83, Pirelli SL26, and the Kenda 329. The shop is very competitive to internet prices so I just go there. I have yet to take the Riva apart in any way so it will be a bit of a learning experience removing the front and rear wheels. It has the factory 18 year old Dunlops on it right now. Too dangerous to ride on those old tires- though I've been puttering around the neighborhood on it. I can't wait to get going on this scoot. It seems to be a good one!

    I have a printed OEM manual from PO. If you don't have a manual, you can find a free copy online.

    Also, Riva riders group on Yahoo is full of very helpful, enthusiastic members. You may look into it if you haven't done so yet.

    I love my Riva 125, though, I feel I need bigger engine sometimes. The scoot is well built and replacement parts are readily available online.

    I downloaded a copy the other day. Haven't had time to look through it yet. Can't wait to get some time to mess with this scoot. I know the carb and/or petcock needs cleaned etc. It had 2-3 year old gas in it when I bought it. I burned through that. I've put about 250 miles on it putting around. The only weird thing it does is a drop of gas comes out of the clear tube from the carb bowl after I ride it. Once it "pees" it doesn't do it the rest of the day. Only a drop comes out. ??? I might go order the tires on Saturday if the shop is open.
    I noticed that you scraped your muffler!!! Holy cow. You must ride like Ben Spies or something! Even with new tires I don't think I'll be able to do that.

    Enjoying owning a "vintage" scoot so far. I get more compliments on it than my other scooters.

    I'm a Honda guy myself, and the extra 25 ccs of a 150 is a big deal to me. But I enjoy reading your trials and experiences, because I've been there so many times myself and, so far, getting it fixed and right has been a grin. I don't try to mount my own tires because I don't have anyway to hold the rim in place. I found an industrial and truck tire shop that can mount anything from tires on welding rigs or forklifts to massive loaders at the port. Just bring them the wheel and the new tire (they don't sell scooter tires, I asked) and they can pop on the new tire in a few minutes. Sure, it costs a few bucks, but it's worth it. I'm a 67 year old guy with a pretty good back, and I plan on keeping it that way.

    When you finally get the scooter all sorted out and running smoothly, watch out, because that's when you find yourself trolling Craigslist looking for the next one. Now I've got 6 of them, and I'm looking around.

    Trust me it's not that hard to scrape on these. I don't feel comfortable riding in a typical scooter riding position with legs and arms forward. So, I extend rear passenger's foot pegs and use them myself. Much easier to transfer body weight.

    I know Yamaha scooters are not so popular on this forum compared to other brand, but it's OK. It makes me that much special. I'm glad someone like you enjoys this thread. Thank you.

    I used blue tarp and knees for holding the wheel assembly for tire mounting job. I wished I had a balancer and weights to balance the assembly, but so far no vibration from back.

    I am not as vintage as you are but not so young either. But still enjoy that grin on my face every time I ride.

    My new tires are in so I'm getting ready to tear into the 'ole Riva. Regarding removing the side panels, do you just remove the one bolt and one screw then slide it downwards? Any tips there are appreciated. And any tips regarding wheel removal would be helpful too. The rear doesn't appear to be too difficult once I get the side panels off but the front looks a little more complicated. How do you brace the front end while the front wheel is off? Any tips or thoughts much appreciated!!

    Prop up on the center stand. I took front wheel off first. You can make it stay off the ground by placing weight on back/rack, like water jugs. After front wheel is off, install the axle and finger tighten the nut. Place a wooden block or something under the axle so that rear tire is off the ground now.

    Below is what I remember how I did......

    [​IMG]

    [​IMG]

    Place counter weights in back, and remove front wheel.

    [​IMG]

    Temporary install the axle and rest it on a wooden block.
    Remove rear wheel. You could remove most of these parts first, prior to removing the rear wheel.

    Now, the exhaust can be removed.
    Next is the support for the rear axle (triangular plate thing).

    [​IMG]

    [​IMG]

    My right shock upper mount nut is busted and cannot be removed. So, I swing the shock out of the way.
    Then remove the axle nut using air impact.

    [​IMG]

    Once the nut is off, the rear wheel can be removed from the scoot.

    Sorry if I missed something.
    Hope this helps you.

    Good luck.

    H-man, How often do you change your oil in the Riva? A thousand to twelve hundred miles is what I've timed the changes at and the oil looks very good for being such a low quantity without a filter. I know appearance means little, but draining the old oil through a strainer has never left any debris. There is a small amount of soot like substance, but less than I would have expected.
    Valvoline 10-40 ATV oil, (has more zinc with an SJ rating) has been my choice.

    I change oil every 1000 miles on this one,,,,
    Or, should I say I try to change oil every 1000 miles.

    First few oil change was done due to other maintenance issues forced me to do so.
