The newest drag racer gears up!

[YENKO DEUCE REGISTRY]

Thanks Jeff - always good to compare setups. Ours is pretty close to yours:

Our setup:
• BZ1, 3x3 (I was told! Crank does say 3”) Dyno 125 cam
• 33mm, .8 & .7, 57 pilot with 195 main, mixture screw ¾ turns out
• Polar Jr primary clutch with 15-28-22 ramps, purple spring, 12 grams on the arms
• Gaged secondary, 38 helix, blue spring, 4th hole
• 14/84 sprockets =’s 6.00 gear
• 18x8x8 tires
• Last run:
o RT = .014
60' = 1.929
330' = 5.502
660' = 8.763
MPH = 73.73

CHT - start = 153
EGT - start = 624

CHT - end = 239
EGT - end = 957

After conferring with others, and a few conversations with Huddleston, I've made some changes:

- took 2 grams off the arms, so I've now got 10 grams on them
- put the red spring into the Gaged secondary, probably the same effect as the Gaged specific 'blue' spring but its more common and an easier reference point
- put the 38 (roller) helix into the 5th hole to slow the engagement down a bit
- resetting the timing, was probably 150 thou in the hole, and will go to 350-400 thou
- installing a new NGK B6HS plug, had an NGK from the Yenko in there - probably not much impact, but...
- moved the rear sprocket / hub so that the chain is dead center between the frame rails. prior owner had the hub on backwards
- installed new rear axle bearings
- installed new brake rotor and pads, corrected the caliper install as it was literally floating - prior owner had it installed wrong
- changed main jet from a 195 to a 185 to get the EGT temps up at the big end
- changed fuel bowl to a Huddleston unit with the quick change jet option, which means that I removed the acc pump rod

There's probably more, but I'm tired of working on it - and need to run it to find out where we are. Season starts this Saturday, but we will miss Day 1 because of a baseball game. Might get a TnT in on Friday night.
