The details below are copied and pasted from a suppliers web site, note that the 1A is a maximum charge rate, a normal 12v battery should be charged at the "TEN HOUR RATE",  Ie  one 10th of the rated capacity 40 amp hour battery = 4 amp charge rate, for a 6v battery it is advisable to half this. A battery which is charged at a higher rate will give off excessive gas and get very hot, resulting in a possible explosion as here.

Normally a very easy bike to start, turn petrol on slightly flood carb by pressing the button on top of the carb float chamber for a few seconds, put choke on (lever to slack cable), retard ignition a bit, press down on kick start until compression felt, pull decompresser press kick start a bit further release decompresser open throttle very slightly and give the kick start a good heavy kick, repeat until it starts, if all is well with bike it should start with one or two kicks.

Hi Guys

I restored and registered a 1946 BSA B32 completed in 2010, the V5 states "first registered 4th June 2010", on the front bottom of the V5 it says "declared manufactured in 1946". this bike qualifies as Historic for road tax and MOT purposes.

I trust this clears up any confusion.

This is the said bike.

Hi

You will need a dating certificate from The Royal Enfield Owners Club, Vintage Motorcycle Cub or similar recognised outfit, the date is based on the frame number so you should be OK, but to be sure why not ring one of them and ask the question?.

Annice Collett  Is the person to ring at the VMCC and she is very helpful, the number is  +44 (0)1283 495102

Not 100% sure if the primary case oil is totally separate from the engine oil on this model, but if it is try using ATF in the primary, or you could if desperate use the cable tie on the lever trick.

After three Months if the oil pump is worn, which it almost certainly is then a lot of oil will be down there, the oil pump is bigger on the return side than the feed side so eventually the oil will be returned to the tank, while this is happening it will be getting thrown around by the flywheels and up the pistons where it will burn and create a lot of smoke, also it will probably be pushed out of the engine breather and make a mess on the bike and the ground.

Anti wet sump vales are fitted to this engine but in BSA's infinite wisdom you have to split the cases to get to it, an easy answer if you regularly leave the bike for long periods is to fit an after-market valve in the oil feed pipe these are available BSA specific which screw straight into the crankcase in place of the original adaptor, failing that drain the cases before starting or put up with the smoke and mess.

Hi Wetdog,

 Not sure if any where built as early as that but they where 3TAs built to T90 spec with alloy barrels so the 9-1 would fit in, have a look at this web site and contact Justin with the info you will find him very knowledgeable and helpful.    http://www.triumph-tiger-90.com/

"this bike is fitted with a concenric carb , is this correct for this year ?",  yes this was the first year that the Concentric was fitted to this bike.
