I've eaten freshly poured Captain Crunch with cold milk and it wasn't that crispy going down the pipe as Your 83 twin shock conversion is on the pipe!! 👍
I thought the 83 490 was the single shock alpha one, sure it was in UK. Steve Dixon now team yamaha manager was my best buddy growing up, he loved maico s back then, he ported and tuned that beast to the max, it was so fast and sounded so crisp. He d wheely it with me on the back, I d be literally hanging on for dear life. People at amca meetings uk would watch Steve completely split his engine and get it back together for his next race, what a mechanic he was. So glad I had ten years competive amca racing was the best days of my life, even now in my mid fifties I still sometimes dream I'm racing what a sport ❤
That paints a wonderful picture ✨ The 1983 was a monoshock but many were converted to Twinshock for the current thriving Twinshock racing scene. Send Steve round to mine with his toolbox 🤩 All the best 👍👍
I had a go on one that was single shock but the swing arm had the eye holes for twin shock WP front and I can't remember if it only had 4 gears it had so much compression it was difficult to kick even with the decompression lever had to lean it on something because I couldn't touch the floor for a 9 half stone 15 year old it was terrifying but memorable sprocket size of a dinner plate
@@dan_ridge back in ‘83 I raced in the Open Expert class and remember a bunch of guys who where not happy about breaking the shock on their ‘83 but don’t remember a conversion to return the bike to the much better ‘81 twin shock. Is this a modern adaptation or is it one that was the “in-the-know” fix back in ‘83?
The bike came with the Keihin copy carb on it and genuine jets/slide/needle. It's out of stock at Racebase now but plenty available on ebay for not much money! www.racebase.co.uk/product/copy-keihin-carburettor-pwk-38mm-s66-air-striker-supplied-with-genuine-keihin-jets-slide-and-needle/173 Just make sure you use genuine jets/needles. Somewhere like TM Racing sell genuine Keihin jets tmukonline.com/product/keihin-main-jets 👍
