Triumph Specialist West Yorkshire???

Where in W.Yorks are you, Ashley? If Thorne is anywhere near you then try this lad. He used to service my Trident 900 when he worked at Adi's place in West Cowick before Adi decided to pack it in for other other ventures. www.pjmotorcycleservices.co.uk is his website. Trident needs a service soon, before its MOT, so I must make an appointment to see him!

 

Ashley.
Welcome to the Family if I have missed you. Do drop us all a picture of the steed. Try the old youtube you might get help to do it your self. Also you know if carbs have been messed with they need re setting and balancing again and they do need to settle down first.
Ride Safe

Good question, I’ve not heard of any independent triumph bashers in West Yorkshire other than the obvious dealer in Shipley but PJ motorcycles I had heard of with good reports

 

This guy "Dave" is the mutts https://www.themotorbikeworkshop.com/ and a triumph trained tech..

 

I am not clear from the OP if the jets are original sizes (38 or 40 pilots and 100 mains) with standard airbox and exhaust. Air screws should all be 2 to 2.25 turns out......and all synchronised to open/close simultaneously.

Black smoke is either oil (probably more on the overrun more than accelerating) or a very rich condition. There are various possible issues with float levels and torn diaphragms that might arise.

The question is, Ashley, are you up for having a look?

 

You'll need a proper spark plug spanner with a rubber insert to grip the plug . This one should work though I can't remember what size plug it is and I think you need an elbow jointed one for the middle plug - it's obstructed slightly by the frame backbone.

You might need to check that it will fit the 18mm hex on the plug.

This is the type that you'll need for the centre plug

In fact this might actually do for all of the plugs, but, depending on how long the plugs have been in there, you might need some extra leverage on the T-handle. Apply any extra leverage with some caution as this type of spanner is usually welded together and can easily break at the T-joint.

Before you do the job buy some of this

and lightly grease the thread portion of the plug before re-inserting it. This should help prevent the thread corroding and getting seized in the head. Just be sure not to overtighten the plug when you replace it!
