Re: Villiers board tracker BAD NEWS!
I have never seen one of these in person, but it looks like it has a air vane type auto choke, make sure its opening.. did you pull the flywheel yet?

Re: Villiers board tracker BAD NEWS!
Put a new high performance spark plug on it. Carbon fouling can cause the electricity to ark to the carbon trails on the porcelain on the combustion chamber side of the plug and you wont get a good spark. Plugs wear out 2 ways, the actual metal contact will corrode and burn away and the carbon tracking will render the plug useless. I just learned that if you take a plug out of the head and put it in the wire and ground it to the block and turn the engine over and you see a spark, doesn't mean it will spark inside the head. In a compression situation, the more compression the less spark or fire that arcs across the plug poles. If you had a plug test unit with a compression chamber (they used to be as common as a TV tube tester machine) you would see that the higher the pressure the less and less the plug spark until it would not even work. So, but a brand new plug on it, preferably a little hotter as you say you have blackend tips, and it may fire easily.

Re: Villiers board tracker BAD NEWS!
Thanks guys for everything.
I have'nt been able to come here for the last two days.
The engine was taken apart to check the piston rings.
The bottom ring (oil) was busted so that was the problem.
A whole new set (3 rings) will be placed, but now I'm having trouble finding them. I'm waiting for news this afternoon.
Then I'll have the valves turned and a new sparkplug as Cobrafreak said.
I'll get back to you as soon as possible.
Thanks for helping and keep rollin'

Re: Villiers board tracker BAD NEWS!
Hey there folks.
I have'nt posted anything for a while because not much as happened.
Yesterday I finnaly got the piston rings ordered from http://www.villiersparts.co.uk and I'm waiting now for them to arrive.
Meanwhile the btr is all taken apart. I hate to see her like that.
Also I took this interval and I'm almost finishing building this for our kitchen:

Hey there guys.
My piston rings have arrived. Original Villiers parts!
I'm gonna get them on today!

Re: Villiers board tracker GOOD NEWS!
Just wanted to let you know since no one else chimed in about it.
That special pulley system that you have is called a "variator". The scooter you got them off of was "dual variated".
If there is anyway you can you use them I would. It was a very common thing on Motobecane and Puegeot mopeds back in the day and basically is a way to have a transmission without having a gears.
Thus if you can use them the bike will go faster specially since these little 4 stroke motors were really only meant to sit at a constant RPM.
The only worry I would have is if the dual variated system came off of a 2-stroke then the engine you have may not get to a high enough RPM for the pulleys to function.
Keep it up!

Re: Villiers board tracker GOOD NEWS!
You're right Motopecane.
I believe I made a mistake by using just one part of the sistem: I imean, i've only used the cent clutch and not the variable transmission part attached to the original engine's shaft, wich was replaced by a pulley. And also, the original engine was 2 stroke 50cc from a scooter. These are problems I have to solve and I'M COUNTING ON YOU GUYS FOR HELP! 8)
Right now I'm really happy because the engine seems to be in very good shape.
As I said, the piston rings were replaced, the valves were turned and it got a new sparkplug.
The carbureator was also tuned.
It now has an impressive amount of compression (kicking the !%#" out of my hands while pulling the starting pulley's rope) and it goes at first attempt.
I removed the exhaust tube: an open window to it's guts. It got rattier.
This week will be the "clutch problem" week.
I'm considering turning into a lever / belt sistem.
What do you think?
Thanks a lot and keep rollin'

Re: Villiers board tracker GOOD NEWS!
I can vouch for the clutch lever. It's fun to operate on the side of the tank.

Re: Villiers board tracker GOOD NEWS!
Yep, I like it also, but I also want to have some chain in it.
Beau's bike has something like that.. If I go that way I'll have to ask for his help.
I've been considering having a direct transmission and I could run it near my dad's house no problem. The thing is I would have to cut the spark to stop..

Re: Villiers board tracker GOOD NEWS!
Cutting the spark is cool, but you don't want that as your only means to stop engine power to the wheels. That would be DANGerous!

You cut your womans head out of the pic! Get the carb issues fixed?

Re: Villiers board tracker GOOD NEWS!
:lol:
Yep.
The carb is tuned, i've got new piston rings and the valves were turned.
It's all sharp now.
I'll be strugllin' with the transmission issue today :x

Re: Villiers board tracker GOOD NEWS!
(DON'T CHANGE POST RIGHT AWAY CONSIDERING THE NUMBER OF CHARACTERS!)
Thanks very much for the input guys.
The engine is runnin’ very nicely. I can get it to idle at low rpm making a really tasty sound.
The carbureator is leaking a bit. Don’t know why, but I guess it’s part of the charm. I’ll deal with that later.
The clutch is giving me a hard time, cause I cant seem to decide what I’ll do. As it is, it does’nt work, and I guess the problem might be the ratio between the sprockets (42 in the front to 36 in the rear wheel), or the fact that the pulley attached to the engine’s shaft is not the original variable thing..
There are two options from my point of view:
Nº1 – Keep the centrifugal clutch assembly like it is, but build a shaft that goes from the free outer casing of the clutch (the one on wich the pads engage) to the oposite side of the bike (right side) and weld a 12 tooth sprocket on it, engaging the chain to the 36 teeth sprocket on the rear wheel.
Pros: Don’t have to chop off everything I’v built so far; possibility of a correct ratio between sprockets
Cons: It’s difficult to get everything correctly alligned; there is a possibility that it won’t work because the problem may be on the pulley attached to the engine’s shaft.
Nº2 – Chop off every thing related to the clutch and build a belt / lever type of transmission.
Pros: No big ratio issues because the two inch pulley will drive a belt to a 20” or 24” rim; it would look cool.
Cons: Never done it (but on the other hand I’ve never done nothing like any of these); might be difficult buying the belt; might have to redo some part of the rear triangle.
Help me out guys.

Re: Villiers board tracker GOOD NEWS!
I vote for option 1 first and 2 second. If 1 doesn't work you could always go to option 2 later. Can you explain exactly why your current set-up doesn't work? Any hope of hooking up the variable transmission the way it is set up from the factory? I hear good things about Variable transmissions.

Re: Villiers board tracker GOOD NEWS!
Hey there.
I think that it does'nt work because:
1 - I don't have the first part of the transmission (I threw it away
) that's attached to the engine's shaft, having replaced it with a common pulley
2 - I welded a 42 tooth sprocket to the free case of the cent clutch, and that's what's pulling the rear wheel sprocket (36 teeth) - wrong ratio!
The wheel spins but not with enough torque to move the bike.
What do you think?
