Title: 48 servicycle project in MN
Post by: carryall on June 05, 2013, 07:02:27 PM
Started a 48 servi to ride.  Currently waiting for parts from Wayne M. to install a 212cc motor kit.  Looking forward to getting it up and runnin'.  It's nice to belong to a forum and benefit from others experience and share solutions.  Here's pic of what I've got so far...

Hello guys,  you are correct... Harbor Freight Predator engine.  I got a great deal on one, and Wayne said he has motor mount plates/kit to fit so I don't need to "chop up" the frame.  Not quite sure what it all entails but I'll trust Wayne knows what he's doing.  I had to repair the seat support spring that was broken off at the neck when I got it.  I ended up welding a mild steel bracket to the neck area and using S.S. bolts to attach the spring to it. (welding spring steel can be tough)  I was looking for a close up pic of Waynes motor mount plate and engine kit set-up to see what it looks like.  Anyone have pictures of it?

You either have a very comfortable garage, or a very understanding wife to let you bring that thing in the house!

Very nice looking bike.  I have not seen one of Wayne's kits.  Please post some pictures when you get it.

Thank you.  I wasn't sure about the "John Deere green" but it turned out nice with the old leather seat.  As for my "garage/shop",  I live in what was supposed to be, a "seniors only" condo and the rules say I can't work in the underground parking area so I "sneak" projects up in the elevator at night when the old ladies are asleep and work on them in my condo.  (I'm only 50yrs old)  I've built ALOT of small bikes in the corner of the living room over the past couple years like Honda CT90s, Honda Cubs, various mopeds, etc...) By trade, I work as a steel fabricator, so I do the welding, motors, and major painting at work and do the final assembly/detail work at home so my grandson can "help" me when he's over on the weekends.  "We" just finished a '76 Yamaha DT100 and designed/built him a small sidecar for it, so we can take trips to the river to go fishing, or to the D.Q. for ice cream together.  (He's too young to ride on my big bikes... ZR7, V-Star)  That's how I got the ServiCycle.  A neighbor liked all the little custom motorbikes he's seen me work on/ride around, and asked if I wanted another project that he had up in a garage attic collecting dust.  Too cool to pass up I figured.   When I get my stuff from Wayne, I will post some pics of project as it gets built.

Nice bikes!  Come on down to Portland, Indiana next month for the VMBC meet.

That would be nice, but I gotta work while I can. I'm having prostate cancer surgery soon and need to save money for my time off while recovering. Not to mention I'd probably come back with something new on a trailer. LOL.  Are you bringing a bike to the show?

Yes, I will probably bring 3.

I used to live in Indianapolis and go to the Indy 500 museum a lot. BUT, If you are interested in airplanes, especially WWII aircraft, you really should visit the air museum at Wright-Patterson A.F. Base in Dayton, Ohio.  It is the most incredible collection of aircraft anywhere!  They have HUNDREDS of them and include everything from the Wright Flyer to the YF-22 and everything in between.(also some of the space/NASA stuff)  Every time I've been there I have learned and seen new/different things. It's the only place I know of that you can actually walk up and touch the plane and appreciate what it would have been like to fly them in combat.  They even have a movie theater that plays various educational movies and gun pod footage.  Awesome place to walk around.

I do ww2 reenacting & often get to play in and around some of the ww2 war birds.  It is awesome to have a radial engined fighter bomber buzz you at tree top level.  I've dumped a whole magazine of blanks into a Mustang that flew so low I could look right at the pilot.  I had a B24 fly right over as the bomb bay doors opened up so we could look right up into the plane (in real life we would have been having a bad day.....I'm usually one of the bad guys).

Someone has to be "the bad guy".  Ya carry a Mauser 98 then?  On a Servicycle note...I got a call from the guy I got my Servi from, and he found a box with the original glass teardrop shaped tail light lens and bracket along with the headlight trim ring with reflector and bulb. SCORE!  I assume these parts are in short supply cause I couldn't find any on "the web" anywhere.  I'm kinda paranoid the tail lens being held on with just a little spring tho? I also talked with Wayne M. and he said my "stuff" will be shipped out on Monday.  Yaa!  Hopefully, I'll be tinkering with getting the bike on the road next weekend and get some pics up of the motor plate and associated parts for the engine install.  Where should I post them?

That is a lucky score that he found them for you. Doing those shows sounds fun. The best I've got was watching F16 fighter jets do target practice with there 20mm Vulcans standing on a tower level with the planes leaning as far out as I could. It was look right plane fires look left bullets hitting the ground and close enough I could of spit on them. Still wished there was cell phones then.  :'(

I share the same paranoia with my lens as that was the only piece missing on my bike when I got it. The spring does actually clip it pretty well though.  I run one of the glass marker lamp lens(they come up occasionally on ebay, check for zephyr) when I am just putt-ing around but will put my original one on if I manage to get into the judging while in Portland.

That's a great idea "CARTJOCKEY".  I just bought a amber glass lens and base for a Zephyr, off E-Bay for about $25.  This site and its members are a much appreciated source of info. I just removed the gas tank from the motor I plan on using,(plan B) and am thinking about making a "cover plate" over the governor/throttle linkage to clean up the look of the engine. At first I planned on using this motorized bike set-up. (plan A)  I may end up re-doing the air filter/carb housing, but will wait till I get it up and running. (looks like a outboard engine LOL)  Then the muffler will come off and I'll fabricate a more appropriate motorcycle looking exhaust pipe that runs back towards the left axel too.

I removed the governor and built a simple bell crank linkage.  Helped clean up the motor.

Until I get it running I wont know how well it runs with the governor.  Did you have issues with the gov., or just got rid of it to simplify things Rick?

A governor's goal in life is to maintain a constant (the case of a motor, the rpm).  In a motorbike application, you need more flexibility to control speed.

BTW I need one of those mowers....maybe I wouldn't be able to break it as easy.....I managed to break both craftsman mowers this week....

So I can get rid of the springs and associated "arm" that goes to the throttle linkage then? (sorry for dumb question but, I'm not real familiar with these type small engines)

You need to remove the internal parts.

It was very easy.

Does everyone do this mod. to the motor, and is the valve spring "swap" necessary along with the disconnection of the "low oil sensor"?
Title: Re: 48 servicycle project in MN
Post by: carryall on June 09, 2013, 09:34:54 AM
While opening up the side case the gasket tore.  Where do I get a new one? or can I just use gasket sealer ya think?
Title: Re: 48 servicycle project in MN
Post by: oil-lamp on June 09, 2013, 09:40:34 AM
If it didn't tear bad yes use high temp with the old gasket. Then a trip to the local lawnmower shop should be taken you might get lucky.

When removing the side cover on a Briggs or engine like that you should always consider the crankshaft endplay when re-assembling. The gasket acts as a shim to make sure the endplay is set correctly. Just make sure there is enough endplay there before making the decision to omit the gasket. I would suggest using a gasket every time.

I disconnected the low oil light, because on a motorbike, we lean these over while turning and I didn't want the engine to quit.

I wonder how well these engines run if the fins were removed from the flywheel & the air shields removed (it would make it look less like a lawnmower engine)?  Mounted on a motorbike the airflow might keep it cool enough.

People do this all the time on motored bicycles.  They seem to run just fine.  When under load, you are moving, and when stopped, they are just idleing.
