Keihin 34mm PJ

[Dustin87R]

Anyone running a 34mm oval slide PJ on their first gen T3? I picked up an 85 with that carb on it and I'm looking for suggestions on where to start with jetting. It's stock except for a Uni filter and the silencer. The 34mm ships with a 152 main and 55 pilot jet but the previous owner replaced them with the largest available and then drilled them out before realizing the intake boot was trash.

I would start at 160 and creep down as needed.

Thanks for the reply! That gives me an idea of what jets to order.

Here is some pages of Keihin carbs jetting specs people used on their TRX250R
http://www.trx250r.net/forum/intake-fuel/36-jetting-database.html

They say they run like 42-55 pilot and around 152-162 main jet. 3rd or fourth clip position.

I typically try to jet the mid range rich for recreation trail riding, but that's just me.

Thanks for the info! I've got some jets and an intake boot headed my way.
