I'm going to take my new sphynx and my buddy will have his r1 yfz. Should be a good time.
-
cool , I been riding there for 15 years I hardly see any R action tho we should meet up
-
I know the feeling think I'm the only r riding up here. I'm sure we will meet up being probably the only r's their.
-
Mike, what kinda chassis did you out the Sphynx in?
-
86 chassis, stock a arms, Marvin shaw shocks front and back. +8 swinger.
-
You need to get to Bako in February, helluva race!
-
I'll try, to make it. Sounds fun.
-
Was a great event. Only saw two r 's out their. My sphynx killed them. Beat a couple 4mm banshees too, my bro r1 yfz beat a lot big banshees. A north shore banshee 20mm titanium steller frame killed everyone. Their jockey took 10 min to line his quad and was the fastest.
-
Nice to here the sphynx was running good. I wish I would of had the money to get that from Jared. It is a sweet motor.
-
I saw some vids on fb, looks like good spot
-
Lot of big banshee and raptors but the north shore racing 20 mill in the steller frame killed it every time. Took him 20 min to get his bike lined but when he finally ran it didn't lose once. He wouldn't run the r1 yfz though guess he just didn't want race anything but banshees.

Sure is. The mid to top end is crazy. Pulls so hard. She beat my bro's jerry hall lt 500 dyno'd at 75hp and I think I was a little lean, highest jet I could find was 220 still a little a learn, she ran good but would fall on face until 1/4 throttle. Never got hot though.
-
Well hell, wish I would have known about this since it's only 10 minutes from me...

I posted about it a week ago, trying give people a heads up. North shore drag racing has been doing it for three years now.

Maybe my bro's wife was taking pics videos but she focused more on his r1.

How does this sphinx compare power wise to your last one?? Not reliability, we know where you stand on that...Lol I was curious if your first sphynx was as quick..

Starts first kick, power wise, double the pull of the coc motor, with better top end.

This sphynx would stomp my other sphynx. The mid to top is the big difference.

Does it seem rich or lean where the hesitation is below 1/4 throttle?
It sounds like you have the wrong needle in the carb and may need to change to a needle that has a steeper taper so that the needle is smaller near the tip. The flow area, at full throttle, between the tip of the needle and the needle jet is very close to the main jet flow area. When these two areas are close to being the same, changing the main jet does not change the fuel flow appreciably at full throttle. When I have a Keihin carb that runs clean when I have that large of a main jet, I make a 2 taper needle so that when I change the main jet it will make a noticeable change.

lean up hear she had a lot of bottom end, none done there. Power would not kick in until 1/4 throttle.

I am not understanding what you are trying to say. Are you saying it has good bottom end below 1/4 throttle in Flagstaff and no bottom end in Phoenix below?
