Ride report. Adjusted the needle to the leanest setting and went 1/4 out to 2 turns on the air screw.
Still needs a leaner pilot jet to crisp the low rpm. Currently a 55 pilot. Plug is nice and brown/tan.
Roll on power is way better from the bottom of 2nd gear coming out of turns.
Sag is set at about 90 mm with the forks dropped all the way.
I want to try 100mm of sag but the bike is hooking up great and I'm not sure if I want more Traction.
Turning feels great but I need to play more with handlebar positioning.
I need to get some time on the mx track and see how it does.
Shoundn't have any bottoming issues with the suspension.
My neighbor has a tight little track and it felt good on little doubles and sIngles.
Felt good to ride a little and adjust levers and jetting. After a long winter I'd like to ride the 250f a few times and get into shape but the carb is being fixed up.... so 500 @ the track it will be tomorrow morning or Monday afternoon.

I might add a flywheel weight. I've never tried one before.
How do you guys like a flywheel weight for mx with these motors?
mikectanker:
Just ordered the Chinese hydraulic clutch kit on ebay.
I saw some guys on thumpertalk had good luck with them. Just got to cut my new grip off and make a little adaptor. For $40 I'll make it work like the guy did on his Kx250. I doubt I can get the grip off with the goo I used
RoostDaddy:

Currently 1994 pwk stock carb
Air screw 2 turns out
Main jet 178
Pilot jet 55
Needle 82R (stock)
Clip in top/leanest position
Fmf gnarly and fmf Rm250 silencer
Stock reed cage with Boyesens
Stock 1990 cylinder
Prox flat top piston

I'm not sure but I think one step leaner on the pilot and needle should be perfect with an air screw adjustment.
Any advice is welcomed.
Not sure if it's worth putting my vforce 3 on in place of the stocker.
