Is there a specific Triumph tool that can be purchased for altering the mixture screw ? Can it be done with the carbs in situ?

I have a tool I made out of a CK 110 deg angle drive adapter (~€10)

If you fancy a spin out down to my place I'd be happy to help you with the carbs, maybe do a balance 1st? (I've all the tools & space under the car port to work.)

Cheers
Mike

As ever thanks for the info. The offer of help is very welcome Mike but getting away isn't easy at the moment. We now have a wee boy in the family and the little girl is not two yet so busy times. He was born two weeks ago.

Getting away...

I can't see a problem BB - if you take the triple, the girl can follow on the ST and that leaves the VFR for the lad. The Mrs can then have a bit of quiet time while you're all out of the way :D


I'll say this; that day will be here in the blink of an eye, believe you me :eek:

On topic, I got sick of burning my hand using a screwdriver bit and bought the tool from Morgan Carbtune. Expensive but makes the job much more accurate, easier and safer.

Hey, congratulations on your new son :)

Btw, you haven't said if there's a particular reson you want to adjust the mixture screws? I've not found it makes a huge difference to move them off a 'base' setting. If you've some perceived running issue, I would balance the carbs 1st - that does make a big difference.

Cheers
Mike

No specific running issue with the bike, it's flying along fairly good.
What i have noticed recently is an odd spit back into the airbox while she's ticking over. Is this an indicator of the mixture being on the lean side? I would be curious to see how many turns out mine are set at as i have ignored them completely. Maybe i should continue with my hands off approach if all is well?

The only time I've had a spit back is occasionally when starting with the engine hot. I reprogrammed the Ignitech to give two revolutions before initiating sparks when starting & it hasn't done it since. (For various reasons I explained in the main thread, the Ignitech isn't quite as slick as the Triumph igniters when starting, tho' only marginally.)

Most likely the spit back relates to the dead spark & an occasional failure to fire on the right stroke. Could be a slight blockage in a pilot jet/circuit or maybe a poor connection in an ignition circuit. A bit of unburnt fuel just catches on the next (non-compression) stroke? I suppose it's just possible there's a slightly tight inlet valve, if they've not been checked in a lot of miles?

I just bought one of those motion pro tool carb tools. Didn't like it. I'll sell it if you are interested.
