have a 59 c15t distributor model running points and capacitor ignition how do i replace the points gubbins with an electonic sensor do i need to fit a battery and buy a boyer black box and sensor or can u just get the sensor for mushroom and wire it into the capacitor ignition system which im assuming is 12 volt as its running a 12 volt capacitor. just want shot of the prince of darkness points so i can start the bugga easier ! hopefully !. anybody got a back wheel /hub with a bolt on sprocket to fit as its got a road wheel at mo and is too high geared, 46 shud be 56, sprocket is cast into hub.

me mate has one on his its as supplied for pit bike, fits cub manifold with a bit of filing on mounting holes. the chinese copies are half the price.

Just got 59 c15 t as far as i know internals standaed but has road back drum 46 teeth would puttin 11 tooth gearbox on givin 4.2 to 1 be low enough ?

DONT KNOW MUCH ABOUT it but iv heard that when bsa started fittin 21 instead of 20 front wheel for trials they had to change yoke angle to avoid that happening.
