New to the form

[SecretMoist]

Hey everyone! I'm new to the form and I wanted to share one of my bikes with y'all. It's a 1997 Triumph Tiger 900. I picked it up Labor Day weekend 2021, and it hadn't run in about 2 years. I rebuilt the carbs with OEM jets, changed all the fluids, patched a small hole in the bottom of the gas tank, new battery, and a small bit of electrical work. Got her running about 5 days later, and she's been running rather rich ever since. Fires right up, but reeks of gas. Constant rich, white smoke coming from the exhaust no matter how long it's been running. The carbs have OEM brass caps over the mixture screws, so my question is how would I go about setting the mixture right so it runs smooth? I'm 22 from Ohio and I've been working on bikes since I was 18. Any help will be greatly appreciated! You cannot see attachments on this board.

Hi and welcome to the forum. 

I'm not too familiar with the carbed Tigers so am unable to answer your question, but I'm sure someone will be along to give you some pointers.

Hello

What a nice looking steamer.  And by the sounds of it, it is actually producing steam!

I would post your question over in the steamer section and it will get noticed by a few more specialists.  No doubt they'll figure out the answer for you.

Because this post had a very clear technical question, I decided to move it here, so more people might see it and hopefully help out. I have never done the carbs on my Tiger myself, but perhaps there are others that can help.

It sounds like your float needles aren't seating properly. The seats themselves can get worn, and the needles will show a ring on the tapered point where they seat when they are getting worn.
Fresh fuel smell can also be the gas cap venting or dumping fuel down the overflow hose.
Mikunis aren't as easy to rebuild as Keihins, but they are rebuildable. If you've had them apart once to replace the jets, you know how fragile the needle and float setup is, but I'll still recommend caution when taking them apart.

Just sonic cleaned my carbs for the first time even though the bike is running good and the plugs look purrfect. Only noticeable problems were gasahol o-ring corrosion and brass staining.  Have yet to re-start as I'm waiting on shims Checked the valves, obviously never been checked at 37k miles, all out but 2. Hopefully those miserable looking o-rings will survive till a rebuild kit gets here.
  I'm in the States too with a '98(Showa forks. Keihn carbs) Just bought it at the beginning of May and have put 1100 miles on it.  It had been a bit neglected by its previous poseur owner and not as much neglected but bodged by its previous, previous poseur owner.
  It now has a home with me and will be a keeper.
