Hi Go,
Just finished the final quality control checks on hundreds of "mushroom" lifters, and will ship yours tomorrow. Maybe I go a little too far on quality control, but it is part of our company policy at EZ Motorbike to make sure we only offer the best. During my checks I actually found one lifter that was off by .002", but after more research I discovered it was the original I sent as a sample [I found it because I ended up with a odd number, as we ordered them in sets]. It looks our new vendor takes quality control seriously.
I wouldn't spend any time adjusting the carburetor until you install the new lifters, because it will change slightly after the install. The lifters alter the performance in many ways including the idle settings. When you install the mushroom lifters please set the clearance on the intake at .006" and the exhaust at .008" [I set mine at .005" and .007"]because the new lifters are so precision. The new lifters increase the duration, lower the valve train stress, lower the weight, hold the valves wide open longer, but most importantly make the motor far more durable [bullet proof]. The mushroom lifters help all new edition Whizzer motors including a stock WC-1 because it reduces the "snap" and the lifter "rolls" over onto the camshaft ramp. Because of the lighter weight the new lifters also help reduce the "pounding" of the valve seats when the valves are returning to the closed position. Many have upgraded the WC-1 motors with the NE cylinder kit, but continued to use the stock .150" lift camshaft, the mushroom lifters will also enhance the performance in the lower and midrange of the converted motors.
Converting to the mushroom lifters will help every version of the new edition motors, so it is a "win-win" upgrade.
After the lifters are installed and the clearances set, warm the motor up for approx. 5 minuites [ride it, don't let it sit and idle]. With a warm motor adjust the air mixture screw for maximum idle speed, then turn inward [clockwise] about 1/16 of a turn to make the low speed mixture a little on the rich side. Remember the adjustment on the 22 MM carburetor controls air, not fuel, so turning it clockwise [just a tiny bit] makes the flow richer. The best place to start is to adjust the screw all the way in [careful, don't over tighten], the back out approx 1 and 1/2 turns as a starting point, then with a hot motor find the spot with the higest RPMs.
I doubt you have a 26 MM carburetor because I purchased 99% of them in 2005. The 26 MM has the air mixture screw under the front of the carburetor and therefore adjusts fuel, not air.
Happy New Year,
