    Wink Are you going to Scarabeo Fair?

    Sometimes being a wrench means helping your friends with their bikes. Today was help my friend with her Aprilia Scarabeo. Mostly this mean putting on some new Shinko tires we sourced from Treats yesterday.


    Something was leaking. I think it was at the valve cover. Tightened it up a bit so we'll see.


    Got to try out the bead breaker that Greg gave me. Works so much better than jumping on it with my feet!


    Had a bugger of a time getting the rear axel nut to break free. Repeated lubricant, removing the extension from the wrench, and having my friend sit on the back of the bike with the brakes pulled tight. It finally broke free. Don't worry that torque wrench isn't a torque wrench. It use to belong to a friend's roommate. It failed as a torque wrench so now it's a fancy breaker bar!


    The axle seems to be a bit loose. I need to check into this one.



    Fresh tires on the Scarabeo.

    Wink GPR Hauler

    I went hunting for some bits today. The local hardware store didn't have what I needed so I headed off to the Home Depot. Hay, as you can see, it was a good time.



    I found some parts, but one of the things I needed was a rod, but how to carry it home on the bike?

    Wink Eating in Layers

    Greg has been taunting me with photos of his bikes in all these cool places one would ride. So recently I've been taking snaps of the Silver Bike as a response. These have been showing up in this thread--of course! Today GL and I rode out to Bolt Labs, with a quick visit to the Local Taco Bell. Can you say seven layer burrito? Sure, thought you could. I've been feeling like the Silver Bike moves out rather quickly for a stock bike. But today riding with GL, and getting totally dusted I was with no uncertainty made aware of the true slowness of a stock bike. Have to suck it up until the Wicked GPR comes back online.

    Wink The Gila Reed Block Challenge!

    Over on MA someone challenged my Derbi knowledge. They should know better. Below is the post, since this info is relevant here too. The Gila reed block mount, as near as I've been able to deduce is the same as the AM6--but here I gladly admit I don't know that for sure.

    ==============================

    Quote Originally Posted by Dave & Bummerzz

    Who doesn't love a good challenge? I'm a bit surprised though that you cat's haven't learned that when it comes to the GPR stuff it's really difficult to trip me up. I think Bobby might know more about these bikes than I do, but it would be a really good competition. ;D

    Okay lets open up a brand new Gila kit from Treats, and grab the reed block.


    Lets compare this to the Derbi EBE075. Upon first inspection we can see the holes are not going to line up.




    But knowing this is MA I'll even put in a couple of the mounting bolts to let you see that all four are not going to line up.


    Next lets check out the Derbi EBE050. Again all four holes do not line up.




    Now we will inspect the Derbi SENDA engine. As we see these holes don't line up either.




    Last we can check the Derbi EBS050. And again the holes don't line up.




    How about we compare the Malossi reed block with the Gila. As we can see there is over lap due to the oval design of the Malossi mounting holes. This is one of the features I really like about the Malossi. You can run it on your Gila, you GPR, your RS50--it's just a great versatile design.


    As far as I know that's a pretty complete sampling of the Derbi engines that came to North America. I don't have any of the Derbi DB Euro3 engines, but their intakes are supposedly the same as the EB Euro2 engines.

    Why do you have a "Gila" reed block that matches up to a "Derbi" intake manifold? My guess would be that you either don't have a real Gila reed block, or you don't have a real Derbi manifold. Or maybe your Gila reed block isn't from the Gila kit for a Puch--which is what most people consider a Gila reed block origin.

    Got some more info. The guy had a Chinese rip off of the Derbi engine, and a reed block from an Athena kit. So he had neither Derbi nor Gila parts from whence he deduced his position.

    in the moped world I sometimes consider anything that needs minor filing / drilling/ or elongation of holes to still be considered bolt on, lol.

    I was running an AM6 vforce3 reed block on my gila in 2009...

    Get your confidence back with Aprilia.

    caution: the use of motorcycles may be habit forming. side effects include purchasing multiple examples of the same bike, in different states of tune, different years, or different models altogether. some motorcycles may be not running when purchased. some parts are no longer available. there are rare instances where aprilias are bought over the internet and upon arrival, they are not as were originally disclosed. there is a small group of people who cannot handle two stroke engines and motorcycle maintenance. if this is the case, you may not be a candidate for Aprilia RS250's.

    Aprilia. Ask your doctor if the RS250 is right for you.

    Wink The Jig is Up!

    We needed a jig to hold the frame while we assembled the bike. Nate came up with this great design. Mount the Jig to the stand. Mount the motor mount to the jig. Mount the frame to the motor mount. Build the bike. Once the bike is assembled remove the jig, mount the motor, and then roll the bike off the stand.

    Wink Ride Ride Ride, let her Ride

    I love to ride, and I haven't had a rideable moto in nearly two years thanks to the lamers that ran over my various bikes. I have to get in as much riding as I can now to catch up.

    Those recent photos are from J-Bots ride in the East Bay last Sunday. Lots of fun roads. They were a bit wet though, so I actually was riding slower than the mopeds in some places! Hey I just got back on the road--crashing would just take me out again. So I took it mellow, and just had a blast. There was a fair amount of rear wheel sliding around going on. That seems to happen on every J-Bot ride due to weather, and road conditions in the East Bay this time of year.

    Wink Nihon Machi

    Wink Presidio

    Today GL and I went for a little ride in the Presidio today. It was a good bit of fun to be riding some twisties again. Then we headed off to the Burger Joint where I got a veggie burger, and sweet potato fries.
