Now For The Cosmetic Mods!

    Well, now I'm finished with all my performance-enhancing mods to Oscar!

    Now I've got him "pepped-up" to the performance level of a STOCK Whizzer at sea level, and probably a little more!

    Here's what I've done to bring this about:

    Opened up the Intake Restrictor. (This gave me the greatest performance gain of all the mods)

    Installed a High-Flow muffler insert.

    Installed Mushroom Valve Lifters.

    Advanced the Cam timing by one tooth.

    Had the Head Milled. (Which included a Copper Gasket)

    Exchanged the #90 Main Jet for a #82 Main Jet.

    Moved the Jet Needle clip from groove #1 to groove #4.

    I want to thank all those who helped me with Parts, Machining, and Advice!

    (You know who you are!)

    Now I'm happy with Oscar's performance, so it's time to give him a more "sporting" look, so he can appear cool and cocky while stroking along our Desert roads.

    I've begun this program by installing Riser handlebars, and my next project will be making an upswept exhaust pipe, such as the one on the Montana Whizzer, my all-time favorite!

    Here's Oscar with his new Riser Bars. (They're still not the same as on the Montana Whizzer, but they're the closest I could find!)

    I would start out with a steel stem because that alloy one out in the breeze like that with those bars as leverage looks like an accident waiting to happen.

    OK, so where do I get a SHORT steel gooseneck with two clamping bolts?

    My alloy stem has a rise of 5-1/2 inches...too high!

    I ride on rural desert traffic! I refuse to ride in traffic! My average riding speed is about 18 MPH up here.

    The probability of my encountering any situation which would result in a leverage-induced stem failure is exteremely remote.

    I want a shorter goosneck for cosmetic reasons only.

    So Hal,
    Which bars did you finally decide on?
  5. Hal the Elder

    I bought the Wald #870 Riser Bars, from Niagara Cycle Works.

    Did you see the bars on the famous, legendary Montana Whizzer?

    Here's a picture of that bike that I photographed from the screen of my Monitor:

    I think these are the most beautiful handlebars ever clamped to a gooseneck!

    (I'm also going to do an exhaust upsweep like this Montana Whizzer)

    I think you should be able to lower the goose neck by loosening the Allen screw on the neck. It should drop down pretty far if I remember correctly.

    I tried that, Jim...the gooseneck is bottomed out as shown.

    Hal, there are a lot of places you can look for the cosmetic bits to tweak the look to the way you want. I went 50s retro with the look of my Whizzer, adding a springer seat with crashrail, twin round mirrors, Chrome gooseneck, retro pedals, the tool bag on the handlebars as well as one behind the seat, the vintage tank decal, the retro-style turn signals, small red (right side) and green (left side) reflectors (replacing the huge amber ones below the seat) and the two-tone paint. Retro items I was fortunate enough to get with the bike were the whitewall tires, the headlight hood and the chrome fender tips.
    I get a lot of my stuff from BikeWorldUSA ( or Memory Lane Classics ( The only problem with Memory Lane is that they have only a fraction of what is in their catalog listed on their website. BTW, the chrome gooseneck was from Memory Lane.

    I checked out BikeWorldUSA and Memory Lane, but none of their stems have the secure double clamping bolts. Does your stem have twin bolts? If not, would you say it's secure?

    I wonder if I could saw my gooseneck off about 3" and saw the Allen bolt off to match?

    Your Whizzer is sure a beauty! I love those fender tips!

    It would look like a dream with Riser Bars! (Just my opinion.)

    No Hal, mine just has the single bolt. It's a traditional Schwinn-style forged gooseneck. It's the one listed on MLC's site under bike parts: stems: Chrome Forged Stem.
    By the way, I forgot to mention I replaced the original bars with 28" half-moon bars. I'm not a real fan of the risers, I like my handlebars wide (because I am).
    Thanks for the kind words about "Thumper"!

    Love those exhausts!!

    WHAT DO WE DO??????????

    But Kilroy...

    ...would that stem that you have on Thumper fit into the fork of my NE-5?

    (MLC doesn't list a price for that Chrome Forged Stem.)

    Would the internal clamping expander make the stem secure in my fork?

    Hal, Thumper is a 2005 NE5 with no mods to the fork or steering tube, and that gooseneck holds firm with just the standard wedge (expander) system. The diameter of the chrome gooseneck is just maybe 1/32 inch smaller (I guess because it's not metric), but that hasn't been an issue. The gooseneck was around $25 when purchased from MLC at the Trexlertown (PA) bicycle swap meet a few years ago. I don't know if the price is still the same or not.

    That's good to know...Oscar is also a 2005 NE5!

    Would you have a close-up picture of your gooseneck?

    What breed is your Avatar Dog?

    We recently attended the annual High Desert AKC Dog Show, where 1151 dogs were entered, from over 150 breeds!

    The Best of Show was won by a Welsh Corgie. (Tailless Pembroke type)

    Hal, I don't have a close-up of my gooseneck, but I'll try to remember to take a shot and post it tomorrow. As to my avatar photo, it's of an English Springer Spaniel named Duke. It's not my Springer, but one that was up for adoption last summer. I was going to try to adopt him (as a companion for my Springer), but someone beat me to him. I use his pic as an avatar because I get a kick out of his happy face.

    Oscar is sure looking great. You have put so much 'love' into your bike.
    Kudos to You!!

    My ex-wife loved the dog shows!
    Out of all of them we attended.....she never even placed.

    You mean she was never even a contender for "Best of Breed"?

    (Oscar thanks you for the compliment!)
