British Bikes / T 100 68 carb/starting problem
« on: November 28, 2021, 10:39:26 AM »
I have just fitted a new concetric 626R 300 carb to my machine & it has become a very reluctent starter taking 10+ kicks to start

I have a 108 pilot jet & 200 main jet needle is on bottom notch , I do prime the engine ie. tickle throttle fully open then 3 kicks ignition off

a choke is fitted but makes no diffrence at all at any position

I do get cylinders firing but it just does not chime in

 
taking the plugs out they are barey wet , fuel flow is perfect I have both taps on to start ignition (Pazon) is spot on

once initially started hot starting is no problem the only thing not checked is float height I have not touched this from receiving the carb

all input gratefully received "worn out of North Wales "

having now done just 1000 miles on my machine since a full rebuild SRM timing side bearing / new sludge trap / crank regrind / rods /new cylinder / hepolite pistons / rings / head uprated to unleaded / valves /guides / springs / Morgo pump ( dust caps were within parameters )
I do find after a run of 60 miles + ( champion N 4s ) the right hand plug is always sooty ? left plug is always a nice light brown electrode dark outer ( no soot at all )
I have a new  concetric 620 on 180 main needle on middle groove starting is good tick over regular running Boyer charging is 14.4 + volts when revved
just curious about this uneven mixture situation ?

all input gratefully received
PS engine is not using any oil I have just changed from Morris running in grade to Morris gold 40 air filter is a standard new unit

I hope someone can guide me finally got round to replacing the handlebar dip/main/horn switch

the new one has 4 X wire yellow/green/black/white,  black works the horn

I have tried all combinations for the other 3 wires and have got the pilot/dip/main working from the switch

on pilot headlamp switch to middle all is good when I switch to main/dip the ammeter reads -4 this happens with engine running or not
 
I have a good charge to battery 14v + new Lucas single phase 120 w reg Lucas 47205 stator & new rotor

British Bikes / T 100 oil feed return problem
« on: September 27, 2019, 03:35:07 PM »
I have been running in my 68 T 100 after a full rebuild and 500 miles later I let the engine oil drain out overnight and again have no return to the oil tank ?
last time I just let the return pipe hang lower than the engine whilst \I kicked it over till I got a full oil flow before reconnecting the return pipe to the tank now no dribble even ?
I syringed 100ml down the return pipe before reconnecting to the tank
I know I have feed to the engine as I kicked it over many times (plugs out ) till I got oil dribble to the pressure release (loosened) valve but still no joy
 I poured in 2,84 litres of Morris 40 oil  is this the correct amount I am wondering ?
the motor has a brand new Morgo pump new oil lines etc.
I hope someone can advise me on this "situation"

British Bikes / T 100 oil feed return problem
« on: March 04, 2019, 05:32:54 PM »
I have just started my T 100 after a 5 month lay off repainting frame new rims/spokes etc

 it went second kick no problem but I cannot see the oil returning to the tank,

I removed the return pipe and forced oil down it till it was coming out of the end another quick start and still no oil return ?

engine wise before the strip down it ran fine ,I have changed both oil feed pipes and rocker feed pipe for new items with fresh new oil

 and replaced the valve springs nothing else was touched engine wise I hope someone can help me out with this serious problem

British Bikes / Triumph TR 250 1971
« on: February 03, 2019, 09:42:50 AM »
Does anyone own or have experience of the above bike as I have just bought one, it starts fine and runs very smoothly at low revs when accelerating 15mph + the motor seems to die and not respond to throttle position
 when I shut off and come down to under 15 mph it all feels normal ? could I have an electrical breakdown or short maybe  ?

any workshop tips on re installing the front fork legs on my 68 T100

 I have compressed the main spring with cable ties and with gaiter and headlamp bracket on I can "manoeuvre" the whole leg just up into

 the underside of the top fork yoke but not just enough to catch the threads with the top nut

do I have to buy the Triumph tool as mentioned in the manual or am I missing the obvious remedy for this re install  situation  ?

all input very gratefully received

I know this is stupid question of the day as I type  however I am restoring my 68 T 100 and am stuck as to how I can remove the chrome fork shrouds that carry the fork stanchion oil seal I assumed there were small allan grub screws on the lower tapered section but upon clearing away 50+ years of road DNA these are what looks like small tapered rivet's ?
 hoping someone can guide me on removal of these items

I have a T 100 68 and notice the ammeter needle  ( Lucas type) stays in the centre of the dial just fluctuating left to right very slightly even at cruising speed 50/60 mph,

 with the engine running and multimeter on the battery I get a constant reading of 13 + volts am I to assume the ammeter has had its time looks like the original from 68 or can it be overhauled

PS after a ride the battery always shows in the region of 12.7 +
