The problem is one of the instructions: remove air filter...

If anyone knows a Triumph Trophy knows to do this you remove the rear fairing, then the fuel tank then the fuel lines, then the carbs, then the air box, oh and the filter comes as an integral part of air box.

So Looking for suggestions as an alternative fuel additive...

Thinking Quicksilver Quickleen Engine and Fuel System Cleaner just because of above any suggestions.

Why am I thinking additive?

She is lazy to start (Has 8 month old battery that turns her over fine) and has a miss fire until she gets warm (20-30 seconds if that) then runs like a dream... Generally does not want choke, or any revs above idol to start. She has spent to much time in the last 2 years standing but now will be in regular use.

I really don't want to go through the above process as its a pig takes better part of a day. You need to be ridiculously methodical with routing fuel and vacuum lines... I recon its probably damp in fuel or junk in carbs, fuel additive Italian tune up then think about proper cleanout.

I looked into one of those for my shadow and decided that taking the carbs appart, cleaning them properly and reassembling is a far better job

I've used Mannon carb cleaner. It is very good and won't attack plastic bits.

Shell Petrol. If you suspect there is water in the tank then a bottle of wynns dry fuel, which doubles up as a injector/carb cleaner.

I wouldn't be putting any magic potions into a running engine to dislodge carbon deposits . They are doing less harm where they are than if you let them loose .

After 2 ride outs, Any difference?

YES without a doubt, no misfire on starting ran evenly without misfire. I could bring the idol back to 900rpm quicker and after a 5 minute run I did not need to do it again.

Instructions say I should use a measure every tank so still have another 16 doses to go out of the bottle, I wont use every tank as long as she runs fine.

History tells me if not left standing for a couple of months she wont be needing another dose.

Next time I fill my Yamaha it will get a little does as well, because of the improvement it made on the Triumph.

Boat engines are often used infrequently which why I suspect fuel treatments for marine use tend to work better than some automotive brands.

I have hunch you can buy the same stuff for cars at four to five times the price.

I'm glad you've noticed an improvement but what exactly do you believe has taken place inside your engine , fuel injection / carbs etc. to have brought this about ?

Bike has not been used regularly for a whilst, so usual sticky fuel, gummy carbs maybe drop off condensation in tank.

Probably better to do full clean but history tells me it takes forever to get here running right after...

Leave the boat with full tank - ethanol won't have any air to suck moisture out of. I always put double dose and leave for winter with full tank. Not had any problems.

For cars that stuff would be 5x cheaper. Cars don't make holes in the water that need filling with cash
