Hi, I had someone clean the carbs three times and very poorly might I add. So after many hours of YouTube research I found how to extensive cleaning of my exact 3 Mikuni BST 36 carbs. New jets, new float assemblies and bowl gaskets. Used torch head clears to make sure all pert holes in the jets we polished and cleaned heavily with carb cleaner. The bike runs great now but seems to inhale gas. About 17 miles to the gallon. Float heights are set to spec. Vacuum sync is perfect. So somewhat unsure why the poor mileage seeing it’s suppose to get around 40ish. Any input would be greatly appreciated. Thank you in advance. Dan
Whats the mileage? Emulsion tubes worn? Can you smell fuel, could be a leak somewhere? My old T300 Sprint got 30 mpg most of the time and only on a run in summer got 35 mpg.
I must be lucky then. My 900 Trident, averages around 50mpg. UK gallons. That is with cone filters, and larger jets too.
My 94 trident got 50mpg with ease and sometimes bordered on 62/64mpg (20km/ltr-24km/ltr) work done , 3-1 exhaust (open) needles lifted approximately forty thous or more and vacuum bypass port drilled out from 3 mm to 4mm. Quicker throttle response so use less throttle to accelerate as much/hard reach cruise speed sooner at lower throttle opening.
hi, the bike has 16k miles on it. New to triumphs so I’m not quite sure what the emulsion tubes are. Can’t smell gas and don’t have any leaks. New head to carb rubber units. Stumped.
This is not a scam. I’m looking for tips if anyone else has had this type of issue. Hoping for help. That’s all.
The emulsion tubes are in great shape. I just cleaned, polished and used a torch tip cleaner along with lot of carb cleaner to make sure they were very clean.
Dan Mercer Carbs when deeply cleaned like you say can consume a little more fuel but does settle down after about 50 miles. Other than that sorry i am at a loss. Welcome to the family by the way and do keep us all informed to the results just as a help for others. Share a picture of the steed just hit the upload a file button bottom right corner. Joe.
