Found some Iver Johnson parts in my Father-in-laws stuff. Having trouble figuring out if it is the bicycle or the motorcycle. The front end was cut off the frame but still has the Iver Johnson emblem.

I saw your notice about the Iver Johnson parts and could tell you something about them if you send photos.
I am working on a motorcycle...

MOTORIZED BICYCLES:   Squealing when riding posted by: David on 8/29/2005 at 2:20:48 AM
Thanks for the help on my previous clutch problem, I now have another... I got my motor working but when the clutch is engaged it feels like there is something grinding. The is also a sort of screaming noise. I have greased everything in sight, and ensured that the clutch nut is extreamly tight so that is does not slip. I don't really know what else to do. The squealing only occurs when the engine is running and the clutch is engaged, I can give gas to the engine while the clutch is disengaged without any squealing.
Thanks again for your help

What sort of machine are we dealing with here? The only Whizzer I've ever seen in opperation, squalled every time the belt was engaged. I not sure if this is typical, if this is a china engine picostarhawkfire sqealing is very unusual and would probably mean the some grease has found its way onto the clutch surface, which would be terminal for the clutch, although I personally would attempt something unorthodox like spraying the dissasembled clutch w/ brake cleaner and knock off the glaze w/ a light sand paper.

It is a 60cc Grubee Skyhawk, how can I change the friction material in the clutch? Could I buy a standard friction plate and cut it to size? Has anybody had any experience with changing the clutch on a grubee type engine? I ll give cleaning a shot, but I think the clutch might be too far gone as is.
Thanks for your reply,

Try a brake cleaner spray, if this does not work to your satisfaction, try for parts. Mr. Simpson is very knowledgeable and active in motorbiking.

MISC:   Cancellation of Boston Swap Meet posted by: Peter Naiman on 8/12/2005 at 8:36:21 PM
I'm posting the note for good friend Jason Cloutier with regard to the afformentioned Boston Swap Meet.

Thank you, Peter Naiman
The organizer of the Boston Swap Meet at Hibernian Hall, 151 Watertown Street., Watertown, MA has cancelled the plaaned swap since there were not sufficient pre-registered sellers to cover costs, she cannot afford to go ahead with the event. I know that there are some out-of-town people who were planning on travelling to Boston for the weekend to attend both the swap meet and the Larz show. Rather than abandon the swap meet, I would like to try to make it happen.

Since the efforts to resurrect the Boston Bike Swap
have failed, I am inviting anybody that is interested
to stop by for a bicycle yard sale this weekend here
at my house. I should be available both Saturday and
Sunday. I have the inventory of two closed bike shops
and an accululation of stuff collected during the 16
years that I have lived here. The swap meet will be for CR and Bob List members only.

I live in the northeast corner of Rhode Island, only 1
mile from I-95. Please contact me off-list for

MISC:   Larz Anderson National Bike Show and Watertown Swap/ August 14th posted by: Peter Naiman on 7/27/2005 at 1:35:08 PM
A number of events beside the Concours are planned for Sunday August 14th. David Herlighy, noted cycle historian and author will be attending and doing a book signing and talk, the Wheelman will be attending and plan on riding at the show in period dress with possibly giving demonstration on riding a highwheeler. Mavic Wheels which is now a sponsor of the show is planning a demonstration which I will have more information on later.

At 9:00AM Jack Demerest or as most of his friends know him as Five Speed Jack will open the day by leading a ride through Bostons famed Emerald Necklace and return to the show at roughly 10:00AM for the shows opening. For those who want to drop off bikes and go on the ride, I will be at the Museum of Transportation by 8:30AM to take bikes in so those folks can go on the 9:00AM ride.

For more information about the show, please see our website at and thank you to Webmaster Vin Vullo for updating and hosting our site.
I can be contacted on my email address listed with this post for additional information on the show.

Hope to see you all there.
