    Hey Gang,
    I am in the process of assembling the parts and pieces to build a pseudo-old-school Whizzer out of 1955 Schwinn Wasp bike and a 2008 NE5 engine. I bought a really dilapidated 2008 Ambassador II off of Craigslist a few weeks ago. After analyzing the bike as a whole, I decided that the only part of it worth using will be the motor itself (sans CVT), the rear sheave & belt, maybe the front rim,some wiring, and the headlight!

    The head and cylinder are currently in Quenton's capable hands, so I am looking forward to hearing it roar once again. Quenton has been a fountain of great info so far, so I'd like to take this time to say, "thanks man!".

    The plan is to transplant the engine into the 1955 Schwinn Wasp bike I just picked up today. I won't brag, but I darn near stole this thing! I am thinking of stripping it down, and having it media blasted and powder coated a satin black. I'd like to find a set of vintage springer forks for it, but man, those things are fetching prices on Ebay that eclipse what I paid for the whole bike...

    In the back of the hatchback:

    The current tag expired when I was one week old:

    In all its glory :)
    <img src="http://i1188.photobucket.com/albums/z406/mikkojay/Whizzer/whiz005.jpg"></img>

    So for now, I am going to figure out what wheel combo I am going to use, and get started on some custom mounting brackets. I did buy an auto clutch and front drum brake hub from koolwhizzer (thanks dude!), so I'll be lacing a rim of some sort here in the not too distant future.

    I'll post some more pics & vids on this thread as things happen, but for now I just started this to "reserve a slot" for what's to come.

    The ebay auction that had the old springer fork I wanted closed, and my high bid was not even half of what it sold for. I don't want this thing to nickel and dime me to death before it gets started (I know, naive sucker) so Since I already had them, I decided to try swapping in the Ambassador forks just to see...
    <img src="http://i1188.photobucket.com/albums/z406/mikkojay/Whizzer/whiz007.jpg"></img>
    If I am going to go with these forks, I am going to need to trim about 1/4" off the length of the head column. That shouldn't be a big deal. The old Schwinn forks were tweaked slightly, and the goose neck was frozen in place. I had a set of Harley bars on the shelf, so I threw them on. The stance and feel of the bike is actually quite nice. I was pleasantly surprised, since after sitting on the Wasp for the first time, I didn't particularly care for the "feel".

    I found a set of Worksman wheels for a really good price online yesterday at zorotools.com. The total price for a front and rear wheel, shipped, was $153. I also did a quick search for online coupons and found one that knocked another $25 off, for a total of $128. :) The wide 3 piece cranks are also on the way. I'm anxious to see how they clear everything. I am hoping that I will be able to utilize the original chain guard too, but I'm not holding my breath. I like the design of the chain guard, it would be a shame if it ends up not fitting- we'll see.

    Hey Great looking bike. Im doing a 50 Panther Whizzer myself. I am using the modified Monark repops on mine

    Edit: Ive been thinking of getting a set of Felt modified monarks, would you be interested in a set of nice used monarks I bought the new larger springs and stainless dropouts.

    Thanks chainmaker, do you have a pic of your setup? I am also curious about the options for goose neck / attaching bars, etc. The Monarks seem to be built well- I would like to see what kind of stance they provide.

    OK, after a moment of clarity I ditched the shock forks-
    After looking relentlessly, I may end up seeing if I can come up with something a little more unique as far as the front suspension goes. I don't want to rush things, so I might as well stew on it for a bit. I do know that I want something that will be beefy & safe while looking relatively old-school. @chainmaker, I see why you like the Felt forks! Those are nice, but I suppose it would involve grafting in a donor steering tube.

    Ebay always has some nice vintage springers search" bicycle springer fork" they always have some different stuff.

    Congratulations on your find and will enjoy reading your building thread! Your motor is in great hands with Quenton. This bike will be a winner when she is done!
    Take Care,

    I'm looking forward to seeing pics of the finished bike. I'm going to echo what has already been said, and that your engine is in great hands with Quenton. His mods (including lightened mushroom lifters and shaved head w/copper gasket) have turned my Whizzer into a real torque monster.

    Woo Hoo! Just "won" this one- the pics are tiny, so I hope it is not too trashed. Anyway, I got one :) I think the original vintage springer will be a good match for this bike. My wireless connection was sputtering out towards the end of the auction, and I said, "oh great"... But it worked when it counted.
    The Worksman wheels showed up on my front porch today along with the wide crank set. I plan on re-lacing the front wheel using the drum hub that I got from koolwhizzer next. I can't wait to see how that turns out, it looks like a nice hub that will be perfect for this application. I have never laced a wheel before, so it should be a fun learning experience. I saw that there are a few youtube vids on the subject, so I plan on checking a few of those out first.
    I''l snap some pics when that comes together.

    That was a good price. I have forks like those on 5 of my bikes.

    Hi Mike,

    Finished your cylinder & head work. I had to enlarge the intake valve chamber as it was never machined to match the valve seat I.D. I also re-cut the valve seat "block" with a special tool and now the valves seal 100% [liquid tested with alcohol]. Milled head .068", and made a custom .010" copper head gasket to fit the head combustion chamber.

    Hope to ship tomorrow morning.

    Looks like you are locating some quality vintage parts, lookin' good.

    Have fun,

    ^^^ That's some great stuff there- thanks Quenton :)
    I snapped a few pics so everyone could see the "before" situation of one of these typical botched NE5 China factory jobs.

    Here is the cylinder that has the valve seat insert block. The outermost hold down bolt/screw is not flush:
    <img src="http://i1188.photobucket.com/albums/z406/mikkojay/Whizzer/tn_whiz2003.jpg"></img>

    One of the results (how could this ever seal?):
    <img src="http://i1188.photobucket.com/albums/z406/mikkojay/Whizzer/tn_whiz2004.jpg?t=1336806431"></img>

    Starting the decking process via belt sander- note how the bolt heads reveal how high they are. Actually, note how far from flat this whole situation is:
    <img src="http://i1188.photobucket.com/albums/z406/mikkojay/Whizzer/tn_whiz2012.jpg"></img>

    Here is some raw video in case anyone ever wondered what decking a cylinder via belt sander looks like- don't judge the commentary, I was just winging it- and I actually recorded the video before this project actually had some direction:

    Final product, prior to a final hand sanding:

    Thanks to everyone who has chimed in with info and encouragement so far- I can use all I can get.

    Nothing fancy on this one, but I thought I would share a few pics of lacing a drum hub into a Worksman front wheel. It was a little tricky, and I need to true it slightly, but I think it will work.

    One spoke removed from the original hub- here we go...

    More dismantling..
    <img src="http://i1188.photobucket.com/albums/z406/mikkojay/Whizzer/tn_whiz_wheel003.jpg"></img>
    I had to use the drill press to enlarge the holes in the new drum brake hub just a tad to accommodate the 11 gauge spokes. Thank goodness for instructional youtube videos on how to do this, they were an immense help. I used what seemed to be referred to as a BMX 3 cross pattern.

    ^^^ Thanks Quenton, looks beautiful :)
    Man, I cannot wait to get that baby fired up!

    Tonight I dismantled my Troxel seat and realized the upper pan is rusted to oblivion. I was thinking of recovering it with black sheepskin, but now I need to decide if I want to attempt cobbling a new pan out of a piece of sheet metal or not. Hmm...

    Looks like some care was taken on that head, nice!! Hopefully I can find a 300 head and send it off to Q for some love.

    Hi Chainmaker,

    If you don't have any luck finding a "300" head, let me know as I might have one with minor fin damage I could part with. I only use 100% perfect parts on my personal show bikes, and just might have one close to perfect you could use.

    Although installing a "300" cylinder on your "H" motor would also add additional power, the valves could be replaced in your "H" cylinder with similar results.

    Have fun,

    Springer Update

    Well good news and bad news on the forks-
    Good news- They showed up and at first glance, don't look too bad.
    Bad news- The base of the steering tube appears to have been re-welded at some point, and the steering tube is too flippin short!

    I'm not too sure about what stock lengths are on these things. I was mainly hacked off about the Billy Bob welding job- heck, I could have done better than that.
    EDIT: I just asked the seller for a refund. After looking at the brazing, I just don't know what to think. For all I know, some hack (even worse than me) could have blobbed some brazing over a serious problem in his garage with a propane torch. I think I would feel paranoid riding a bike, especially a motorbike, with these installed.

    The pics:

    <img src="http://i1188.photobucket.com/albums/z406/mikkojay/Whizzer/tn_whiz_fork002.jpg"></img>
    Stock length anyone?
    <img src="http://i1188.photobucket.com/albums/z406/mikkojay/Whizzer/tn_whiz_fork003.jpg"></img>

    Edit: I thought about welding up some kind of fix, but I am going to attempt a refund first. These forks give me the creeps.

    On a lighter note, I received my cylinder and head in the mail today too- thanks Quenton, they look great!


    Edit2, I found another steering tube with a 6 1/8" length as well. Does this mean that this is the typical steering tube length for these vintage Schwinn springers? The column on this bike looks like it is going to need 7" in order to accommodate all the hardware. Hmm...

    I messaged back and forth with the seller and his kindness was a breath of fresh air. I think I am going to try one of these:
    <img src="http://i1188.photobucket.com/albums/z406/mikkojay/Whizzer/steer_tube.jpg"></img>
    It was about 20 bucks and has the length I will need. Since the pivot bolt goes through the middle of the whole assembly, it seems like it should be pretty stable. It might make a small change in the geometry of the fork, but I am willing to try anything at this point.
    Now that the forks have reverted back to "waiting for the mail" status, I think I will start on the engine mounts.
