Hi sportscarpat,
The person's track record is 100% failure over a 10-year period concerning clutches. The automatic clutch used on the NE5 bikes is a sound design [he didn't design, but copied another clutch, look at the inside of the clutch adapted to fit on the 2001 Whizzer]; only "cheapness" caused the problems. Had the person listened to my original test results and invested about $10.00 extra in the process during mfg. it would have worked well. He simply had to use a hardened bearing sleeve, as any engineer will tell you, NEEDLE bearings won't survive a SOFT bearing surface. Needle bearings, because they are small, rotate at very high speeds and must ride on a polished, HARD surface. I sent modified test clutches with the hardened sleeve to Whizzer, who forwarded them to him, and guess he just didn't like the idea of one that actually worked. In fact he removed the only needle bearing used in the new edition motors for cost reasons [a really bad idea to save less than $2.00].
In fact had he listened to me on the manual clutch it would also work 100%. The only problem with the manual clutch was the transfer from the original vintage Whizzer clutch to the metric version. The clutch arm is simply the wrong length period! It is too short or too long, take your pick. If the arm were longer the front belt wouldn’t hit the bottom of the front bottom belt guard post. If the arm was shorter you could use the same front belt as the Vintage Whizzers did [AX26]. Funny how the original vintage Whizzer clutch worked on over 250,000 motorbikes, and this guy in Taiwan couldn't figure it out, DUH!
Please consider the following before wasting your money........... The clutch assembly is way too wide and will most likely place way too much stress on the mount........ He shows the unit installed on a bike and still needed the front belt tensioner..........He doesn't even use a QUALITY front belt, but a cheap FHP belt......... Why didn't he use the rear clutch mounting system on the motor?.............. Because he didn't take the time to locate the clutch in the original location, the rear belt will be too long [whoops, I see he included a very cheap made idler to take up the rear belt slack]............. The stock belt guard will not fit over this wide clutch [are we to ride without one?]..........A quick look at the pulleys tells me the ratios are in outer space concerning a Whizzer [looks like 20 MPH top end]. Stock ratios on a Whizzer are approx. 9 X 1, not 19 X 1.
As you can see, I simply see more of the same........Bad engineering, made with sub quality parts from someone with a less than stellar track record.
Have fun,
