I never holed a piston on any of my 2-strokes but I fouled a few plugs. Frugality is a valuable tuning tool.

It was nice to see the initial gauge readings were all on the rich side with the exception of the front float level inducing a lean. Now I can get a little more risque with my tuning.

The rain season has commenced in the Pacific Northwet so test and tune opportunities will most likely be few and far between.

Sieg, do you get that thing out on the track at all? And the GoPro would be a second set of eyes? stayin on the pavement is kinda important if your into that sorta thing

Super nice tight work BTW, love you car as you know....

Thanks.

To date it's never been tracked.......not even at the local school which I can't say that about a few of my dirt bikes back in the day.

Did you use to work for a circus? Great welding Mr. Contortionist.

I found an article that helped me out a LOT!
http://www.rodauthority.com/tech-sto...y-carburetors/

So I read this article a few times and drove the car to get a feel for the transition points then started making changes ONE at a time and test driving.

My goals were to get idle in the 13.5-14.0 range, cruise in the 13.8 - 15.3 range, and WOT in the 12-13 range. Before adjustments I was seeing 12.5-13.4 idle, 12-13 cruise, and 10.8-11.5 WOT.

First change on the Holley Ultra HP 650 was an idle air bypass adjustment Which gained a few 1/10ths at idle. I have to add now that I have this a/f system.......I should have bought it a long time ago. It is so nice to make a 1/16th or 1/8th turn adjustment and see immediate results.

Second: changed the orange accel pump cams back to the lean stock pink cams. Picked up a couple 1/10ths

Third: changed the main jets from what I knew were rich 72's back to 70's (carb came with 70's) and another positive result but still rich in the cruise mode.

Fourth: changed the primary mains to 68's, another gain, still rich.

Fifth: changed to idle air bleeds to 73's from stock 70's, that got it in the ballpark of 13.5-15.0 in the 2,00-2,400 rpm cruise. In 2nd and 3rd gear at 3K it will go 15-15.9 which bothers me a little, but it's only for a second or two and the gauge spikes all over the place so trying to nail the average is a little tough without data acquisition.

Sixth: changed the accel pump cams from stock pink to red (slightly leaner than orange) as by leaning the overall circuit it developed a hollow off idle throttle response and a little stumble on light clutch engagement. The red cams were a big improvement.

End result is idle 13.5-13.8, cruise 13.8-15, WOT 11.7-12.5. There appears to be some very brief spikes depending on throttle application input speed and rpm but it's much closer and it runs very good overall. Never a hint of pinging or detonation. The Ultra HP has adjustable metering blocks so further fine tuning can be accomplished via idle restriction circuits, power valve circuit, and emulsion circuits via jets in the metering block.

FWIW - It's damn tough to monitor a sensitive gauge and while hammer the throttle and shifting gears.

It really is the simple things in life that bring the greatest pleasure.

More pro-tinkering toys to install now that the rains have come to the Pacific Northwet.

After SEMA a front suspension tune up and installation of Dynalite rears discs will commence once I figure out the best e-brake cable connection option.

It's all in the details Scott! It's always (well sometimes anyways... ) fun fine tuning and seeing the results. Good job! In regards to the E-Brake cables - look at Control Cables. They have a multitude of options and great to work with. I just bought all my stuff from them. Talk with Greg.

Thanks Brent, I followed that link when you posted it a while back, didn't have a personal contact though, I'll give Greg a call and see if we can create a solution for my application.
