November 7, 201015 yr Hi Just purchased a bike for rebuild and wondering if anyone can advise the following: 1. What psi should i get when the bike is kicked over? Im getting a max of around 75 psi on the gauge? 2. Kick start sometimes engages sometimes not any suggestions? 3. Also got no spark from the coil, ammeter giving 12000 secondary and about 1 -2 ohms primary? (Book says 6000 and 5-6 repectively?) 4. Have checked the wire to the coil and ammeter showing 1.5 ohms as per book, but when kicked over doesnt seem to emitting any charge? any ideas what this should be? Appreciate any advice please. pete
November 7, 201015 yr Hi Just purchased a bike for rebuild and wondering if anyone can advise the following: 1. What psi should i get when the bike is kicked over? Im getting a max of around 75 psi on the gauge? Pressure depends on how much oil is present. Ring wear/condition should be judged using end gap and appearance of piston and cylinder walls 2. Kick start sometimes engages sometimes not any suggestions? Taks clutch cover off and have a look at the mechanism 3. Also got no spark from the coil, ammeter giving 12000 secondary and about 1 -2 ohms primary? (Book says 6000 and 5-6 repectively?) Your resistances may be a bit different to the book if your coil is not the standard coil. 4. Have checked the wire to the coil and ammeter showing 1.5 ohms as per book, but when kicked over doesnt seem to emitting any charge? any ideas what this should be? Can't understand your question. If you want a rough test to see if the magneto is working, disconnect the HT coil from the magneto, set the multimeter to volts and measure what voltage you get between the wire to the HT coil and bike earth as you kick it over. There should be a brief voltage pulse each time the points open if the magneto is working. Appreciate any advice please. pete
November 8, 201015 yr Gday, it sounds like you have a CDI type coil fitted, this coil does not have enough primary resistance and can increase current flow in the primary side of the ignition. You need to check the stator coil, points and condenser, it is probably where your problem lies. Cheers, Stork
November 8, 201015 yr Author Thanks guys for the response. Will investigate further and let you know what happens. Pete
November 8, 201015 yr Author Sorry re my 4th question - i did a static check using the single black wire coming from the crankcase and this reading was 1.5ohms as suggested in the book! pete

January 6, 201115 yr Author Finally got the old beast to fire on all one cylinders! Replaced points, condensor, woodruff key, spark plug, coil and she finally burst into action. Rode round the garden and promptly fell off!, breaking the clutch lever bracket! never mind stripped down ready for the powder coaters! Cant decide on frame colour SILVER or WHITE??????? Will post some pictures as soon as poss
January 14, 201214 yr YES silver methinks Thanks what colour did you go for? I did mine in silver, and painted, rather than powder coat. http://motorcyclerestorations.blogspot.com/2011/12/defining-moment-in-any-restoration-i.html'>http://motorcyclerestorations.blogspot.com/2011/12/defining-moment-in-any-restoration-i.html http://4.bp.blogspot.com/-5LAT_vfdDtQ/Ttf1YD2nZHI/AAAAAAAAAn4/RTMVzgWiwIM/s1600/080.JPG Regards Simon http://motorcyclerestorations.blogspot.com/

January 16, 201214 yr Author Been some time but finally sorted. Built my own powder coating set up including an oven big enough for bike frame and have done the frame in silver. Also coated just about every component possible! Hope you like my photos. Still a ways to go to complete the bike but all the hard work done! http://s1063.photobucket.com/albums/t511/youcannapolishaturd/?action=view¤t=IMAG0140.jpg http://s1063.photobucket.com/albums/t511/youcannapolishaturd/?action=view¤t=IMAG0165.jpg
January 17, 201214 yr Interested to know how you built a booth as powder coating is quite expensive. What other equipment is required?
January 17, 201214 yr Author Interested to know how you built a booth as powder coating is quite expensive. What other equipment is required? I first built a blasting cabinet, again big enough for larger parts. Also bought a bigger compressor and a blasting pot off of flea bay! Was just going to do the small bits using a household oven then decided to build my own. Commercial curing ovens are a tad expensive so I built one to my own spec. The powder coating gun was relatively cheap and you dont need anything complex to make a booth for the powder coat as its sprayed at low pressure. The basics required are an oven, powder coating gun/system, powder coating powder, Hanging enclosure to spray the parts and a compressor. You don't need a large compressor for powder coating, but you do need a method of stripping your parts either by sandblasting or chemical stripping. Hope this helps Alternatively if you want any bits doing let me know. Cheers
