I imagine this is a US based forum? Great to see, as I've never seen a Gemini mini bikes forum anywhere else.
So anyway hello from Australia. I have 4 Gemini's: an SST50, a Gemini 50, a Gemini 65 and a Deltek 65 (same as the Gemini 65). All undergoing restoration, 2 nearly finished.
After chatting with Steve Bysouth, our local Gemini expert (perhaps some have heard of him as he's written magazine articles on them), here in Victoria. I discovered that the 65cc Gemini's never went to the USA.
I saw on the forums index, that there is no section for the 65's... So I just wanted to put the idea out there.
As a precis, the 65's are basically a Gemini / SST 50 with a 43mm bore and a 42mm stroke (61cc). The crank is from the SST 80 (same conrod as the 50 but the crank throw is 21mm not 20, hence 42mm stroke). The barrels can be a Yamaha YJ1 or YJ2 (42mm) bored 1mm oversize (+ perhaps some other 60cc Yamaha barrels?). Head is from a JT1. Same carb but bigger mainjet etc. They do go a little better than the 50's.
Cosmetically the Delteks (candy yellow with a tank sticker and a different seat cover) where the first few hundred serial number wise, and the Gemini 65's (candy orange with a tank sticker) the later ones. I believe less than a thousand were made, making them quite rare these days. Both the 65 models use the SST 80 handlebars and have a slightly longer fork travel / inner tube length.
Anyway I look forward to chatting with you guys.
Thanks,
Hugh (mungus)
