Excellent.

So I'll just order a new one I think. Pretty sure my Y piece is OK, but I'll check before I order.

As far as the balance screw goes, I'm having some trouble with that too. Of course with the front cylinder not running properly at idle it makes it very hard to balance. I did separate the carbs so now it's a bit out.

Does anyone have tips for balancing the carbs properly and should I attempt to do it before or after I get the air screws right.

Also, when I say the front cylinder doesn't run properly, the exhaust is still coming out, puffy but very cold in comparison to the top cylinder. Also, the bike will idle with just the top cylinder but certainly won't idle with the front cylinder. If I hold it above 3k RPM and disconnect the HT lead on the top cylinder, the front cylinder can keep the engine ticking over no probs.

This is what makes me think the mix is screwed up at idle, but if it means something else, please enlighten me.

Thanks again for all the help so far guys.
