UPDATE:
I bought this bike last year with the intent of catching hoonfest, didnt make it there.
Al Gava packed it up and shipped it to ND for me!
I got it together friday night, started at 9pm and was done by midnight with a little front fender and APT smartcarb upgrade acomplished also.
It rained sunday but we had decided to ride. Got 1/2"while we were out, it was good.
Saturday 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.
I leaned it a click when it was raining on our ride sunday, low end it was snappy but smokey. Don't get me wrong tho, it runs good.
I've always looked at the carbs as rich if they don't need choke to start, and I didnt, or should I say couldnt start it with choke.
Since the body of the carb is taller and the slide holds the cable lower you need to remove the cable from your throttle housing and cut 1/4" from the housing. I did and had a tap handy so I deepened the threads also, not sure that needed to be done. From here I have perfect adjustment.
