RE: [TriumphTrophy] Re: Keihin Main and Pilot Jets
- View SourceFYIL The jets in my 1200 are 115's. It's a 50 mile round trip to work so I
decided to ride my bike to work for economy's sake but checked the mileage
against my then '89 Honda Civic. The Civic got 33mpg and the Trophy 30mpg! I
got to work about 15 minutes sooner however. (;-)

Hi Bob, Do you remember what the main jet sizes are? I read that stock main
jet sizes are 105 & 110 for 1200's with Mikuni carbs. When my '96 900 had
the Mikuni carbs the jets were 120 & 125. It had more power with 127.5 jets.
Then I changed to Keihin's searching for fuel economy. The fuel economy
increased a little bit but at the cost of the fun factor. So out went the
Keihin 120 jets and in went 127.5 Ohh Boy, the fun factor is back.
I'm curious, should I have changed the rubber boots between the carbs and
the head when I changed the Mikuni's to Keihin's? Are they the same boot?
He asked if I wanted a few more ponies..... I said H_ _L yes! He opened up
the jets and put it on the Dyno. My carbs have flowed more fuel from the
time I drove the bike off of the dealers lot.
