A quick google of that number turns up mention of a mid-1950s T110 crank.

Identify these bikes! / Re: Arthur Conan Doyle's (Sherlock Holmes) motorcycle
« on: January 03, 2013, 10:33:33 PM »
Sleeve valves and gears-in-rear-hub would both be unlikely in 1905, they were still in the future ??
Although there were some sharp minds on the job, thinking about how such things could be achieved.
It was said that Alfred Scott and someone else in the same street in the same town both applied for an early patent for rotary engine designs, in the same year. Smart street ?

That SV24 registration should be traceable - the records may even still exist, depending on where it was issued. (Surrey ?)
This has to be at least a few years into the 20th Century.
[Should have read all the comments first, shouldn't I.
Has been traced = 1905 ROC...]
Elsewhere it notes that 1905 Roc had external flywheels both sides of the engine.
That monumental high-rise mounting for the numberplate has to be noted !!

Does the choke circuit on your bike fully work - and make any difference ??
Many bikes simply will not start cold without choke.
The FIRST major thing to look at with starting difficulties is the spark plugs.
They should be cleaned, and gapped to the correct gap.
And if that doesn't help, try one ones.
Along with cleaned (or new) air cleaners, and fresh oil in the engine (if its about due for a change).
And correctly gapped and set points for the ignition (if it doesn't have electronic ignition, don't know XJ550 that well).
Along with wiping clean all the spark plug leads, around the coil and wiring etc.
Carbs all synched and idling well when warm ?
Fresh gas in the tank - old fuel seems to evaporate all the lighter fractions- that make it easy to start.
If it STILL doesn't start, try reducing the gap on the sparkplugs, not by much ( a few thou).
If that works, as a last resort, consult back here.
P.S. Happy New Years all.

While urging caution about going to hotter plugs, if the ones in use are a grade too cold, then what other answer is there ?
Assuming is not fouling from oil...
Stale petrol possibility also needs to be sorted out - these days, if all the lighter fractions evaporate off, whats left doesn't seen to burn !

First thing to try is new plugs, and see if it starts.
Or clean those plugs, and see if it starts.
If it starts, maybe time to look at the grade of plug - maybe a grade hotter required. Or less pottering around town. ?
Then - does it idle cleanly ? Adjusted the idle mixture lately - if its chugging black smoke (we can't see your bike running), then definitely a carb problem.
Fuel quality can also affect dirty plugs, burning oil can affect dirty plugs, and weak ignition can affect dirty plugs, so its time to consider those too. Battery voltage still good - measured it as at least 12.3x volts ??

Was just about to question this 'plate', but you answered that.
Indeed, a strap of steel across the 'back' (where we can't see) to strengthen it, and some longer bolts (?), and bobs your uncle. (Where did that expression come from ?). Looks thin enough its surprising it lasted this long - or did the spares dept do a thriving business in them...

« on: December 14, 2012, 12:18:10 AM »Were your two six volt batteries connected in series or parallel? If parallel it would be still six volts which would explain your explosion.
Says it was the old battery.
And why would 2 x 6v batteries in parallel be a problem with a 6v charger anyway ?

Good job you were there to clean everything off.
And not in the firing line.
Internal fault, and spark.
Or external fault, and spark.
Who knows,
Heard of this happening under someone (car) bonnet, however...
P.S.Battery acid is very good at cleaning off chrome. Very quickly....

« on: December 01, 2012, 10:35:31 PM »The chrome is hopeless and peeling off everywhere,
Thats a bit different then - but it does look good in red.
Red guzzis seem to vary greatly over the years in hue and shade - if you say it was a tuesday (martedi) color, none can disagree with that ??

Classic guzzis were red with chrome tanks, anything else is going to be a backward step ? Perhaps better shaped panelling of red on the tank though.
The army superalces were heading towards butt ugly in mil green, with that split twin muffler. Purposeful, but still ugly, beauty of line obviously didn't come into it.
And if your wife likes it red, we'd say thats a very broad hint !!?!!

Should have read down further - all is explained.
Will enquire if someone is perhaps interested in a trade.

Any idea what is different about the BAU to the BA - which are a fairly common type.
