Old WC1 Cruzzer Project

    I picked up a 1999-2004 Wc1 cruzzer the other day for a really good price so I decided to try a new project with a modern reproduction Whizzer. I was aware of the problems with the wc1 motor, but the price on this bike was so cheap I couldn't resist it! Besides it hadn't developed the valve seat problem yet (at least not until the second time I rode it) I was hoping to get a little more riding in before I decided on some upgrades, but since the motor took a dump already I decided to expedite the upgrade process.
    My first Wc1 project was a mess and ended up with me parting the bike out to get my money back. It probably was not a good idea to listen to people who's only interested in selling you parts, but don't really know what the're talking about! I learned a lot from that first mishap and I'm hoping to do better with this one.
    The first thing I did was get a hold of Quenton and ship the cylinder and head to him. He's going to fix the valve seat problem and clean up the ports when he reworks the cylinder and mill the head and reshape the combustion chamber. He's been really busy so I didn't get any time frame on this, but I imagine that this wouldn't take long once he gets to it.
    I also couldn't find out if I should get a new carb for this? It has the original which I guess is a 16mm? Would a bigger carb be a good idea for this or would it be a waste of money? I wanted to add a little power to the bike, but I'm not looking to make a drag racer or do wheelies! Any suggestions would be welcome. I'm not really an engine mechanic and not looking to get too complicated.
    The bike itself was pretty complete and rides pretty good. The kid that sold me this had made a few styling changes to it that's not really my taste so I've been working on getting it back to a more comfortable style that I like. I'm posting a few pics of the bike as I got it and will post a few more when it's done. Don't want to bore you with the details.

    New Carburetor

    Well I couldn't find out any solid info on a new carb for my project so I ordered one from Joe Lin in Taiwan. It was listed on ebay as PZ20 (PFT) carburetor set fits Cruzzer and whizzer WC1-NE5 engines.20 mm (intake size) carburetor with #90 main jet. Don'r really know much about this carb so I hope it will work. Still waiting for some word from Quenton on my engine parts.
    I've been working on stripping the tank on this and getting it ready for painting. I had a really hard time with whatever was on this tank. It seemed to be a combination of powder coat and paint??? Not really sure but there was no primer at all and was really thick! I had to keep reapplying coats of stripper and scrapping on it. You can see the weird deep cracking on the top of the tank. I have another tank I can use until I finish this one. 1zzzzzz.jpg IMG_20140918_114735.jpg

    Nice score! How many miles did the motor have?
    The original carb will still work fine with what repair work your having done to the cylinder and head. The 20mm carb that's shown is a tight fit for the wc-1 cylinder. Round carb works better.

    Thanks Ray. Bike had high miles on it. 1600. Sent the cylinder and head off to Quenton a week ago and have not heard from him. This site seems almost dead. Can't get a single response from nobody! PM me your email. I have some pics for you. I'm really disappointed because we're having what could be the last few really nice days left of weather and I have nothing to ride.

    Keep us posted of the progess lilback, Quenton used to place a small air oil separater(pipe) in the valve tappet cavity, between the valve guides. Best thing he ever made!
    Also, use oil that has zinc with at least 1200ppm-1400ppm (WT. % 0.12-0.14)

    I received my reworked head and cylinder back from Quenton yesterday and was very happy to get it back! I always hate waiting for things like that , but hopefully it will be worth it. I started putting it back together and had to stop when I realized I was missing a allen wrench I needed for the stud conversion kit which replaces the long studs that went all the way from the head. The hard part was getting it all back on without taking the motor off or even loosening it. I managed this by removing the piston from the connecting rod then getting the piston started into the cylinder enough to leave the hole for the wrist pin sticking out. After getting the cylinder back into place I could re- insert the wrist pin and tighten down the cylinder. The whole process took about 15 minutes and I didn't have to worry about messing up the alignment of the motor.
    After putting everything back together and getting the gas flowing to the carb, she fired right up! I ran it for 5-10 seconds and shut it down right away because the bike is in my kitchen! As anxious as I am to test the bike I have to wait until tomorrow as I work nights and finished this all this morning. I want to make sure I have everything back together correctly!
    I haven't taken any photos yet, but the cylinder and head look very nice. It was painted black by Quenton. I didn't receive any info with this, but assume there is nothing to break in? I will post some pics tomorrow after I've tested the bike.

    Well my test ride didn't go as planned. The bike started right up but I had the same power loss that I had before I had the cylinder reworked. I was going to have the work done anyway, but now I knew for sure I had a problem with the carb. I called Quenton for some advice and he reminded me I needed to adjust the valves. He also recommended I advance the cam if it has not been done already.
    I adjusted the valves, .009 for the exhaust and .007 for the intake. I also tore the carb apart and cleaned it thoroughly. I decided not to advance the cam at this time because before my power loss the bike was running perfectly and may have been done by a previous owner. I also don't have a extra side cover gasket if needed.
    After getting it all back together she fired right up, so I was ready for a midnight test ride! The bike ran really good and yesterday I was able to tune it up a little bit and got up to about 30 mph. I think it can go a bit faster. At times I felt like the motor was going faster than the bike although it was hard to tell if the belt is slipping? I'd like to know what the best belt front belt for this bike is? The old speedometer was all over the place so I put a brand new one on.
    I also added a lay back seat post, and borrowed the seat and tank off my Hornet Whizzer. I've also added a new set of handlebars. The bike is now a lot more comfortable and more my style. I may make some changes this winter but for now the bike is done. I've got about $600 bucks in this bike now ( with engine upgrades) so I think I've done pretty well on this. With the work Quenton has done on the cylinder I expect this bike to last a long time.
    Here's a few pics of the bike as it is now before the black painted cylinder was installed.

    I received the new carb I bought off eBay yesterday and put it on this morning after work. I wasn't sure if this carb was going to work or not but I decided to take a chance on it. It's a Keihin PTF 16mm carburetor. This appeared to be the exact model that Joe Lin is selling on eBay for $46 dollars w/shipping. The one I purchased was $34 and ships from the US. The one from Taiwan would take 2-3 weeks to get and because Joe Lin is selling it, doesn't necessarily mean that it's the correct one. Good luck getting your money back if it don't fit. With some eBay bucks I used, I ended up paying $25 bucks.
    One of my pet peeves is paying ridiculous prices for Schwinn and Whizzer parts especially when they are reproduction parts! One guy is asking $50 for a spark plug ignition coil wire because it's in whizzer packaging. News Flash: It's still cheap Taiwanese garbage! Half a dozen scooter parts dealers sell that same coil wire for $6.99 on eBay. Actually it's probably made in China. The US isn't the only country that ships it's manufacturing to China!
    Anyways the carb fit and works as it should. My main concern was the left sided choke lever and how that would work from that side, but it was not a problem. I took the bike out this morning and tuned it in. The engine is running as strong as ever and I'm convinced now that one or both of my belts are slipping. I already have a new rear belt so I guess I will start with that. It's a ax-62, and if that doesn't tighten up enough I may add a half link to the chain. Half links can be had at any Do it best hardware for 2-3 bucks or your local bike shop.
    Here are a few pics of the new Keihin PTF 16mm carburetor and re-worked and painted head by Quenton. I'm going to need some polishing tips from Mason Man to get the motor looking like his! new carb.jpg IMG_20141021_111737.jpg IMG_20141021_111747.jpg IMG_20141021_111821.jpg IMG_20141021_111827.jpg IMG_20141021_111831.jpg
