Back On da Road

Xpongebob · Dec 23, 2012

Hi Guys,

At Least, She's back on the road, after waiting for the right parts : Maney Crankcase, Crank, barrels, Full auto head, JS Conrod and piston, valves, pushrods, etc :

Still need improvements : She has a tendency to die when suddenly closing the throttle and disengaging the clutch, after revving the engine, but I think it's coming from the lightened crank that needs a higher idle setting.

What a pleasure 8) ! (And this forum helped me a lot ! )

See you

Xavier

OH my now that's worth some waiting for. I'd suspect need of a bit bigger pilot jet or raising float level rather than too light a flywheel. MIght tweak spark timing a bit to see if that don't please you. Back on the Road again, what a nice phrase they should make a song about for us.

Sweet. BIG coin. Congrats. Drive.

Very nice. Looks like a fun ride.

Thx !
Carburation seems okay regarding the plugs color, and timing was not easy to set, as maney cranks don't have the rotor key slot at the normal place ...

That plug cap in the photos looks like a Champion WCX600 which is likely to have 10 kOhm resistance. Maybe replace it/them with a pair of 5 kOhm plug caps (and non-resistor plugs)?

Need to check that, but the ignition is a Boyer, resistance values are the same than standard ignition ?

Very nice indeed, now just get on it and ride it, enjoy your hard work and have fun.

Sorry, I don't know exactly what you mean?

Xpongebob · Dec 23, 2012

Sorry, It meant that as this is an electronic ignition (as opposed to a standard one), I was wondering if the resistance values you were giving me should be modified according to that. Sorry It's a bit late overthere... I'll check that later this week, after Santa's visit :wink:

If it is the analogue Micro MkIII or MkIV type Boyer system, then ignition suppression is not strictly necessary (but is preferable to prevent TV and radio interference).

Boyer Micro Digital and Micro Power systems must use 5 kOhm caps or resistor plugs. Significantly more than 5 kOhms resistance is likely to cause some loss of spark energy and I think Boyer Bransden do not recommend more than approximately 5 kOhms resistance with any of their systems.

Xpongebob · Dec 24, 2012

And that is so precise !

Thx LAB for the hint ! I had an issue with my CB500 Four, which doesn't stand resistive plugs, so this wouldn't be the first time these damned plugs would play on my nerves...

Cheers

Hi Xavier , nice bike , you really had made a good job, quite quickly.........Pierre

Xpongebob · Dec 24, 2012

Merci Pierre,
A la base j'aurai voulu garder plus de pièces "origine"... L'état de la machine m'a poussé à faire autrement :wink:

A+

Salut Xavier,

Great work, I'm glad to see you went for the Maney crankcases in the end.
We'll have to catch up for a beer next year in when I'm back in BOD.

joyeux noel et meilleurs voeux pour 2013.

Salut Brian !
Long time, no see ! Well, I'm waiting for you, and not in the kitchen :wink:

Bonnes fêtes, bonne nouvelle année , et à 2013 j'espère !

Please tell me they have dynos in France... :mrgreen:

Kvinnhering · Dec 25, 2012

Merry Christmas to you all.
Congrat with nice bike with potent motor!
Orginal stroke and bore? What cam have you inside the engine? How dose it preform?

Jan

Xpongebob · Dec 25, 2012

Tons of dynos :mrgreen: For once there is something produced back here !!

Jan, I Kept std bore/stroke and cam , reliability is the aim here. And it's still on break in, so I'll need to wait before fuuuull throttle

Merry Xmas !
