    Great report Kelly and Blake. I was afraid while reading the first part that it was going to be a downer. Good to hear this is for real. Not to discount the other reports, but hearing it from someone close to home is that much better.
    I think the wait till spring and the cast version is going to be a little more tedious than usual.

    If Kelly will put his 165 together and then try it, I will probably pass on the test at this time. Life is really complicated right now and riding time for me is going to be hit or miss.

    This whole thread put the Smart carb as a little like the holy grail for the jetting iseues.

    the problem that I face is humidity and temp changes in a ride can change considerably

    I did atempt to buy the airstriker but i might be verry intrested in this one here.

    yep it's not a cheap one but when it realy delivers its for sure a headache less and more enjoyment on the ride eventualy it will break even in some point due to the fuel consumption savings.

    but the main reasoon is for sure the lower emisions the gain in power delivery is justy a nice coincidence:rolleyes:

    Did another ride yesterday. Same bike different place. Nasty rain ride in the technical Jordan creek / Diamond Mill area. This area is full of big nasty hill climbs. Me on my 04 CR125 with APT, Adam on his TE310 Joe on a new KTM 500. Carb is still no joke and performed amazingly well. Hills are far EZ to climb, it has much better pulling power and lugging power. This area also has many transfer roads and quad trails and i got to open it up much more and WOW the top end is in another time zone from the stock carb. So like the first ride, better control, smoother power, much more low end and roll on / pulling power and tons more top. I was topping the hills EZer than my buddies on thier 4 strokes. Actually had to ride the KTM 500 up a few for the dude as Adam had him in over his head most the ride. Pretty amazing. Going to try and install the 165 in the next few days.

    If you index the retainer slot 180 degrees from the slide slot, you'll see a hole I was told, that was intended to accept a screw.

    I'd like to know how it runs in your RM 250...One of my all time favorite off road bikes.

    I can't wait to get the Lectron 36mm PJ carb. This is an improved version of the Original from which several carbs have been copied, including the SmartCarb. The Lectron is only $315 with the adjustable Power Jet. If it works as well as I remember on the old bikes and as well as the Edelbrock Quicksilver worked on my Hondas, I will be tickled. I remember back when we were using Lectrons on Hercules, Pentons and Yamahas that if you dropped the bike the bike wouldn't even stall. Just lay there and idle. Better fuel economy also. Also altitude compensating too. They seem confident that the carb would be delivered with the correct needle and would only require fine tuning. I can't wait to compare to Kelly's report on the APT SC.

    i saw the hole but no screw and not sure i would want one there that could fall into the intake track. Needs a better design IMHO.
