Hi, I'm currently restoring an 85 TT600 and was wondering if anyone has ever fitted the Keihin CR dual carb set up to one of these bikes. I've already purchased the carbs from Power Barn and I was originally told that they'd fit straight on. However this isn't exactly true as apparently they won't mate with the stock airbox. Before I go and re-invent the wheel I thought I'd ask to see if anyone could give me some info on the subject. Also by comparing the original carbs to the Keihin I've found that the Keihin are HUGE. I hope I haven't been duped as they cost me over $500.00!!!
