1985 lt250R Jetting Question?

[quadzilla570]

Ive had my share of lt250's and a few lt500r's but havent rode in a few years.

I picked up an old 1985-86 lt250r which was in storage for 3-4 years and its coming out of retirement. I ordered a new clutch which it needs and plan on just running it and not dumping money into it like my bikes in the past.

HERES MY QUESTION:
The bike once had an FMF pipe which was switched to another bike and never jetted back to the stock pipe which it currently has. It has a k&N filter with no airbox lid, and it has boyseen reeds and been bored 60 over.
The jetting I was told was off

I will not be able to pick the bike up until next weekend and wanted to buy some jets this week. Do any of you have a place I could start at in terms of jetting ???

QuadZ,
My lt is almost the same.Im running the stock mikuni w/200 main, needle 3rd groove.
I ride 100 -3500 feet altitude with this set up.

Do I need to mess with the pilot jet ??

I will get a 200 jet and try from there. When you say the clip is 3rd groove, is that from the tip (pointy end) of the needle ??

Thank You

Also, are you running a stock pipe ??

[Wacky Macky]

I have never messed with the pilot jet. Yes 3rd groove from the pointy end.
The lower groove from the point will get your main jet to flow sooner and the
higher the groove will make the main flow later.

Do you know what the main is now?
