What Have I Done (valve Clearances)

Hi - the 3 bar fuel pressure is with the tank on, with a pressure gauge with some fuel line and some quick fit connectors each end so it can be plugged in to the normal fuel supply from the fuel pump.

A good point about the breather - I have checked that this is clear and blasted brake cleaner down it for good measure!

 

Just checked the fuel flow rate- it is doing just over three litres / min.

 

Hi Sprinter - I can't find a spec for the minimum flow rate. I was thinking would it use 3 litres for a theoretical 60 seconds of WOT throttle acceleration?

I replaced the filter with a Mahle 145, which is the right one, just 1/4 of the price Triumph dealers charge!

 

Hi Speeder. Thanks for the reply. I did a paranoia check under the valve cover at the weekend and verified that the timing was as before I did the job (I had taken pictures). NB: the arrows on the cam gears didn't line up exactly before I started and it ran great, so I put it back as it was.
I also re-checked the valve clearances to check I hadn't miscalculated anything.

New o-ring seals for injectors and throttle bodies are arriving this week, so that is the next line of attack this weekend.

Good job I've got two bikes eh? ;-)

 

Well, new injector seals top and bottom and new throttle body o-rings fitted and it's still doing it. It runs so much better with these new seals, but still bogs down if you give it sudden throttle. Now that I know there is nothing wrong under the valve cover, I'm going to give it a good ride and maybe a tankful with injector cleaner.

So the mystery continues.... I'll keep you updated.

By the way, my throttle body seals where as flat as a pancake and I imagine that were definitely leaking - the bike feels so much better with these replaced. I reckon these should be considered a consumable and done every five years or so..

 

Just to clarify regarding the map - it is the standard Triumph map for the TOR exhaust.

 

Yes the bike has always has the standard Triumph map. I never fancied messing with custom maps. It''s also always pulled smoothly from low revs. Now it bogs and 'stutters' which it didn't used to..

 

Nb: Since I replaced the throttle body and injector seals, it''s no longer idling between 30 -35 steps on the IACV, it''s more like 25-28, so I need to balance the throttles again to get this in spec and then see how it behaves..
