    Thanks all of you for the tips...I think some more tinkering next month...but for now it does "smoke off the line" no sputtering and very quick.Perhaps I should be happy.Also still great on gas....

    Hi I have a aprilia sr 50 year 1997, it has only done 1080 km, I was wondering if anyone knows what modal this year is and what engine type it has in it, also I would like to know how much a leo vince type- zx chrome exhaust would increase my top speed, I think it has a normal exhaust on it currently but it is derestricted and I have had 55 mph out of it.

    thanks :D

    In response to how fast it can go, the Ditech in stock form is limited by things, gearing and rpm. If the rev limit was raised you would go faster with the engine beating itself to death, I'm fairly certain a stock crank is not up to a steady diet of that. The stock gearing is another limiting factor, even if you have a 70cc kit with stock gearing you might get to the top speed faster, and may pick up a mile an hour or two, but given the max revs they run at and the gearing your lmiited.

    I have an 02 Ditech, with 70 cc Malossi, white contra spring, carbon fiber reeds, Leo Vince ZX, 10/41 gears, 6.5 gram rollers, kevlar belt and stock variator. I can get an indicated 70 mph down hill in a tuck, but the speedo is so far off its probably more like 64 or maybe 65.

    Anyway I'm new to this board, its wonderful to be here, its certainly a thrill...
    Ciao

    There's always Weight Watchers.

    Those Aprilias are really nice looking bikes. One guy in our club, Gem City Rollers, has one.

    Seriously, scooters speedometers and scooter owners most are mostly always optimistic when reporting the top speed. When checked with a GPS unit, my Elite 150's speedometer was reading consistently 2mph faster than it was going. And the Vespa speedo is ALL OVER the place. Sometimes high, sometimes low.

    Worse than a Ford Escort fuel gauge.

    Hey all,

    My wife expressed interest in the SR50 and I'd like to get it for her, but we went to go check it out and the seat is a little too high for her. She's about 5' 3" and had to stand on her toes just to reach the ground. I didn't think that would be too good because she's never ridden anything before Anyone know if its possible to lower the seat in any way?

    My Super9 is tall as well. I'm 5'4" with a 30" inseam and I'm on tiptoes. The light weight of the scoot makes it easy to manage, though, as well as getting used to having just one foot down, flatfooted. She can also scoot (no pun intended) forward off the seat to get both down if she's in a situation where she wants to have both feet flat on the ground.

    Thanks Photog,

    I'll share that with her but IMO, as a totally new rider, she'd be better off with something that she could flat foot. I also suggested "scooting" off the seat to flat-foot it, but it didn't seem to be too easy for her to do that when she tried it. I'd be concerned that coming to a traffic light stop in the city, that she'd not be able to get her feet down properly. Appreciate the reply!

    I hear ya'. I'm an MSF instructor and a lot of folks really appreciate starting off with a bike they can flat-foot...it does a lot for confidence. I had a Vento ZipR3i 50cc scoot that was shorter and IIRC I could pretty much flat-foot it or at least get the balls of my feet down solidly. Hope you get the info you're looking for--that SR50 really looks like a neat bike and a good long-term purchase.

    Thanks again Photog. Yep, I think she's more motivated now to find something since gas went up to more than $3.50 / gallon today.

    I am using my SR50 R Factory to commute 49 miles a day. So far so good, but it's going to be nice to get the revs delimited (currently at about 7200) Already got the Leo Vince and the dealer says they have a racing clutch they could install for me.

    Any high mileage users out there? With the weather here in Pittsburgh, I suspect I will be limited to 6000 to 7500 miles a year. Will the priller hold up, or should I go back to my gas hog K1200RS?

    hey scooter dude, great site you got!


    The sr50 sure is a nice bike. But how much two stroke oil does it actually use? Some of that oil is pretty expensive, and i wonder if most riders who own sr50's add that cost when you say it gets great mileage. I would hate to spend alot of money on two stroke oil. Anyway, im just curious to know how much it actually uses.

    The 2007 SR50 I am riding sips oil. Apparently, there is an onboard chip that regulates this and keeps oil consuption at a minimum (mostly for air quality standards, I suspect).

    4 oz to the gallon is fairly standard for scoots that require premix. The clean burnng priller probably uses a lot less.

    Sips is right... hardly uses any at all. I had my oil changed at 5k miles during scheduled service... at 6600+ now & the tank has hardly gone down at all.

    I have an 02 SR50 Ditech, 70 cc Malossi Big Bore kit, Polini for Race 2 pipe, white contra spring, 5.5 gr. rollers, Malossi Full circle crank.

    The issue:
    Put scoot back together this winter, thing ran like a raped ape, no problems whatsover, then last Thursday, after taking on 1.3 gallons of fuel, I got about 1.5 miles from the station, heard a noise like a train, lost power and sputtered to a stop, will not restart.

    I checked the following:
    Variator to make sure the nut didn't fall off and all the components didn't drop off, was fine.

    Checked the other side of the crank to make sure that was intact, it was.

    Checked plug, was black with fluffy carbon, but provided spark when grounded, replaced it.

    Thought maybe it was bad gas, drained tank and refilled with fuel from another source.

    Checked air compressor and compressor line, produced pressure, and held it.

    Removed injector rail, and tried to see if any fuel came out when cranked,
    after 2-3 seconds of cranking it would slightly dampened a towel, (about an inch and a half circle) but not soaked, placed my hand in front of it got a very slight mist but hand was not wet. It seems, my fuel delivary is not happening, I do hear the fuel pump prime for several seconds then stops as it always had. How much fuel is pumped from the injector in a 2-3 second crank cycle, I have heard it's substantial. So I am figuring it might be 1: a clogged injector, 2: a dirty fuel filter, 3: or maybe a clogged or kinked return line. Any thoughts????

    It turns over fine, crank and piston have less the 200 miles on them, bike had oil in it, no error codes, I can't get the bugger started. I have tried floodiing it a bit by cranking with throttle wide open and the restarting, it is only then that there is a fiant sign a life, but not sustainable enough to start or run.

    Any thoughts or solutions would be greatly appreciated.

    Thanks
    Going for broke!

    Moneypit... not sure... I'm not that mechanically inclined so I'm not certain what I would check next.

    Roberto... it's the fuel pickup not getting gas. If you're going to do wheelies, keep more than 1/2 a tank of fuel in there :D
