Hi - I have my '05 Zuma almost ready for prime time. I'm still waiting on some parts (CVT items and 14/42 gears), especially the e-choke. I'm running it just a bit now, only for a few mins at a time, up on the center stand. I bought it a month or so ago, not running and needing top end. I installed a Malossi sport bbk (stock crank, 10mm pin) and compression is about 185. It now has a Dellorto 17.5 PHVA and I'm still using oil pump. It has a UNI filter in the stock airbox and also a Malossi reed cage and a 5mm spacer. It sounds a bit strange, like a pinging or something. The exhaust seems like it's all torqued really well, but maybe I could re-check the torque on the cylinder nuts? Can you smart guys check it out and let me know what you think?

The first thing I noticed was the idle being ~1,000RPM higher than typical. Maybe something is rattling or it's just the noise through the intake side, but it pretty much sounds like a 2T to me.

Thx Brent! I'll be tweaking the idle and A/F after getting the choke squared away. I'll see how it sounds then. Thx for taking a listen and weighing in! Jack
