Hi,

I've got a project sled comming in the shop tommorow and I was just reviewing the specs tonight. A few specs seem odd.

The needle (7 series) ends with -1. *Now I've been rebuilding Polaris for years and that usually indicates the # 1 position on the needle, Is that true for bombardier. (sounds crazy that they didn't just go for a leaner needle jet???)

Also, where do you start good power on these. secondary seems pretty tight (feels like about 18+ lbs???)

I know I'll need to dyno-run it, It's just a currious observation.

I've run a 670 before and the clutch was way loose.

Previous owner said nothing has changed since the day he bought it and always had it professionally maintained

Any thought to the needle spec or clutch?

thanks in advance.
