Team Valley Tune Up

 June 25th 2024

Collected the T3 from Turbopacs at Team Valley.

Left it with them last week.  They offer a range of car and bike services, and use a dyno for measuring bike output.  Thought it might be useful to have the bike put on the dyno to see where it was at versus specifications.  However they also offered to fettle the carbs apparently their specialist is a bit old school and likes to put a good old un to rights.  Spoke to him (Ian) he seemed to know his stuff and is currently rebuilding his Ducati 900SS (owned from new in 1980) so we share some common legacy I guess.  First impression was it's definitely too rich.

Anyhow he's changed the pilot, main jet and and atomiser to the settings below.  And also adjusted float height and an inlet valve clearance.  Balanced carbs.  

Ride home about 35 miles, mix of dual carriageway, country and suburban.  Results summarised.

Tick over - regular not lumpy

Pick up -    Better, less snatchy

Pulling -    about the same

Running -  a bit smoother 

Back at Home

Carb balance - checked with Morgan gadget - spot on.

Took out plugs when cooled down.  

Pictured below.

RH looks good

LH a bit dark, does that cylinder run cooler?

But both way better than previous dark and slightly sooty.

54.8 HP at 6000 rpm

61.5 ft.lb at 3200 rpm

All in all at £336  I think value for money for a sweet running motor and more confidence that it is going as well as can be, and certainly better than I'd ever managed after several summers of fiddling about with limited success.

Finally the manager there (Marc) reported that the Big G had been much admired by customers over the last week, nice to know.
