98cc Villiers
Postby harry76 » Mon Jul 18, 2011 2:51 am
About 10years ago i rode motocross bikes and would turn my nose up at the thought of a bicycle, seeing as you have to pedal and all. Then i got outta motocross and got into cross country, then downhill, then i got into restoring vintage bicycles, and then i motorized one. And thats my new hobby/passion.
Heres my early 1950's Villiers 98cc 2 stroke engine that i fitted to a beach cruiser frame resembling a board track racer. Hope you guys like.....

Or i have a picture section of the bike which is a lot shorter http://motorbicycling.com/f15/98cc-vill ... 30542.html
The tricky bit with these engines is they are low revving so a standard centrifugal clutch wont work (without modification) so i decided on a hand clutch/lever. Ive only just finished this bike and because i hadnt heard of anyone using one of these i went for an 8:1 reduction and that gearing is too high and wasnt very ridable. I got it up to about 20kmh on the testride but because its geared too high it was labouring and couldnt get past that. So im in the process of getting a smaller front pulley and primary belt to suit.
And yes i pedal start it. I just put it up on the stand and pedal it. I have a kickstart on the jackshaft but i need to finetune it to work properly.
And a straight pipe would be fine. CAMNZ has a straight pipe much like boardtrack racers had. I had intentions of doing a straight pipe but when i put this on i quite liked how it filled the gap and looked quite different so i kept it.

I was not going to use a centrifugal clutch. I can't stand them on a motorised bike, its just not how they are supposed to be, I will be using a tensioner on the primary belt similar to yours. I love your lever idea on your tensioner. Looks really old school How does it stay forward when you put tension on it? Is there some sort of lock on it? I have a really small drive pulley for the engine, about 2'? Its very small, so thanks to you i'll use that one My engine has no starting mechanism, no kick starter or rope starter. So i have no choice but to pedal start.
I think i could fab up a straight pipe that sounds real nice, my ucle has a TIG welder so i should be able to weld up a pretty one
And also, do happen to have any spares for these little engines? My engine is missing its ignition system inside the flywheel. It still has the coil but the points and every thing else are gone My dad's friend may have a spare one of these engines but im not sure so im sorta no the lookout for any parts.

I have 2 other complete Villiers engines but no spare parts unfortunately. Keep an eye out on EBay, in "Vintage Stationary Engines" and "Villiers", but you are more likely to get a cheaper one by buying a complete mower like i did and you may get the kickstart as well. Ive gotten one of these mowers complete for as little as $30..... search "reel mower", "cylinder mower"
Good luck and keep us posted. And if you make an account over at motorbicycling there are plenty of people more then happy to help.

The cranks were the standard cranks for the bike, i just heated them and bent them with an oxy set.....

Yeah its pretty cool to live near the beach to go for a ride, its not that nice of a beach to swim at but its nice to jump on my bike and cruise around the peninsula. And so far ive only seen one ploice officer and he didnt seem bothered. and it gets a TON of attention, everyone in the street stops what they are doing and just stares as i go past. I even had an old couple waiting by my bike when i went to the shops..... he said you dont see these anymore and asked how old it was..... i said i made it but the engine is Vintage. Him and his wife waited while i rode off and they watched and waved, and they seemed to get a big kick out of it by the smile on their faces.... who wouldve thought..... pretty cool.
Anyway i made a stationary video of the bike on the stand

Pm me details, would love to see that in person. I was at Duttons Cycles at North Lakes once and an older guy turned up on something very similar chasing a spare tube on a ride up to caboolture.
Cool stuff!
