I must have missed any posting of it on here.
Looks like a winner as easily as that bike started.
What's the story on it?

You should try building a 380AF hybrid. I know guys that have ridden both love the 380. One member on KTMTalk used to have Honda 500s, but after he rode the 380 he switched. A stock 380 is as powerful or more as a stock 500. But it is modern design with power valve that gives it all the low end grunt a 500 lacks. THe 500 can certainly make tons of power with mods, and has good aftermarket support, but the 380 is a sweet motor. The best of an old 500 and modern 300.

So is this APT better to get into than the pulse setup?

dude is gonna be pissed at my replies, haha
I'd posted this in the APT carb thread at traceys on the 22nd
Today in 79f 65% humidity I lit the beast!
The bike doesn't like choke at these conditions.
It fired up good, set the idle, then proceed to break in this new Wiseco equipped top end with some tire annihilating wfo runs down the road, hahaha.
This bike just got home from California Thursday evening, I put it together with it ready to go by midnight Friday.
It's in a gen3 250 frame, the big billet carb cleared the chassis everywhere, cable worked once I clipped 1/4" off the housing like summitboy had run into last week with his unit also.
The clamping flange is not like a cast carb but has a machined ring lower than the other portion to let it grip, could be better.
From where it was set I richened it a click of the metering rod, it's feeling good, excellent in fact. I would like a pinch more fuel up top which requires a different rod, I expect to be certain of this in the cool September riding.
I put just over an hour of actual riding on the bike once I was done fiddling with fresh assembly things like lever positions, etc.
Carb pulls smooth and clean in low gear, doesn't load or get fumbly when geared too tall like trying to get moving in 3rd from barely a rolling start.
Deceleration is better than the pwks from my experiences. They require more fuel metered to keep them in the safe spot on decel than what they actually need for acceleration. Keep in mind that I was riding it to over exemplify the requirement most guys have. I pulled the gears long as possible and decelerated for the same with picking up throttle to see if it would catch up smoothly and it did. Obviously I can't speak for it running hot or cold, i didn't spew any water and I rang the snot out if it in decently tight bush with an 8mph breeze.
The bike has stock porting, stock reed and boot, stock ignition, close 1990 style trans, 14/49 gearing, a 110 tire and a fatty pipe. I chose the fatty from my wall of pipes after seeing the immaculate condition of the stock pipe the bike came with. The stock one is now in the archives.
There's a big storm building in the west, we'll see what tomorrow brings but I'd like to get a few more hours on it, not that I need to tune it at all but I just want to ride the dang thing!!!
I need to change the bars to something lie a CR bend for the ATV style ones on it, swap a set of my wheels onto it with an M5B, and mix some more fuel!
I'm running 91 pump premium with ethanol.
On a scale of 1-10 with the stock PJ being a 1, the PWK at 4, the 38mm smart carb comes in at a 6 with the pulse injected pwk at an 8.
Setup, after purchase parts required (possibly 1 metering rod at 15$), and ease of tuning is going to put these carbs on top of everything else out there.
I will be pulse injecting this one yet.
since that, I decided against the pulse deal, not enough fuel map adjustment to have it make sense.

This saturday I had a BBQ at my house and one of my riding buddies was there who rides a cr250 that i have to say is the strongest 250 i have ever ridden. He was talking shit about how his bike was just as powerful as mine. So i say you should ride it and find out. Well needless to say he hit the throttle wheelied uncontrollably missed my neighbors garage by a couple inches and dumped it in their driveway. After i caught my breath from laughing so hard i told him dont feel bad your just another person that didnt respect the 500 and hit the ground after. Talking about a 500 and actually riding one is a whole different animal. We all know he wont be talking that BS anymore.

Here's my 2 crashes caught on video.
One is my CR250.
To be fair, it had been over 20 years since I'd ridden and that damn slanted root just got me in the woods video.
I don't know how to post it right but here they are anyway,
Enjoy:)
