I have known Earl Larson's son Davey for 30 years. Dave raced both sleds and karts for his father during the 60-70's Earl continued on with the kart stuff through the 90's. GEM the business was sold off to someone who continued some of the Kart parts. Earl died about 8 or 9 years ago and the buildings themselfs were sold off. I helped Davey move what he could out before the sale was final but there was very little time. I did come back with our truck packed with as much as I could bring. I posted what I had here in the classified section but was over run in a few hours. Most all of it went to one very well known man on this board and I would guess much of it has made its way out there by now.Outside of whatever some collectors may have, the rest is gone

Back in 1975 he helped me with a Mikuni/Endo pipe conversion setup on a 74 Doo 440FA...Last I heard they were still doing business as a kart performance company in St Charles,Il

Years ago my father gave me a box of sled stuff from his basement that had a couple GEM items. I have a hr ram tube still in its original box and what looks like a hr to hd adaptor. I've also got a head that looks very similar to the one in the ad posted here. I never knew they made heads,  how can I identify it as a GEM head? Its got some numbers on it, but not the numbers in the ad. He had a '69 Sno-Jet that I would guess was the sled it was all used on because after that he was all Yamaha.

It would have GEM on the bottom corner if memory serves me right

I believe Mario is correct on that....

Doesn't say GEM on it anywhere.  I googled the number on the head and "hirth" and it comes back as a hirth 300 head. Guess the ole man pulled the stock head and let the sled go with whatever he replaced it with.
