Yamaha specs that the Road Star's idle be between 850, and 950 rpms, when properly setting the PMS. Without the bike being thoroughly warmed up, and the idle in the right spot, the vacuum won't be high enough in the manifold, to make the pilot circuit function correctly...or as good as it should. I know this is redundant for some, but for those new who are wondering about this, there it is.   Logged       The administrator has disabled public write access. #550738 jd750ace (User) Front toward enemy Platinum Boarder Posts: 18763 Re:What 900 RPM Sounds like 5 Years, 4 Months ago   SKWEARpeg wrote: [quote]jd750ace wrote: I tried to force the throttle plate tighter a couple of times with the loud handle, but couldn't get it low enough to lope, but at least it's a point of reference for those of you that never had one. The EZ Tach clamps over a plug wire, and an iron core induction loop picks up the high voltage pulse in the plug wire to detect the frequency of firing. Mine seems to work with the clamp reversed just fine, although the unit and instructions tell you the pulse shuold go left to right through the coil. This is the one I have. I had to turn mine over(so the plug wire lay in the slot further) to get it to work well. I was surprised to see yours working fine right side up I have.</span> I had to turn mine over(so the plug wire lay in the slot further) to get it to work well.

I have to be on the 7MM part of the wire to get signal.   Logged       The administrator has disabled public write access. #550743 pastornj (User) Platinum Boarder Posts: 3110 Re:What 900 RPM Sounds like 5 Years, 4 Months ago   I'm definitely running lower than that once warmed up - Thanks for the heads yup!

I'll likely be showing my ignorance here lol... but don't you need to multiply the number shown by two to get the actual RPM since you are only measuring the firing on a single cylinder? Or does the unit take care of multiplying for you?   Logged     -----==========------ 2007 Roadstar Midnight Silverado Cobra Speedster Slashdowns, AIS Deleted, K&N Filter Michelin Commander 2\\\\\\\'s, Reckless Fairing   The administrator has disabled public write access. #550813 SKWEARpeg (User) Platinum Boarder Posts: 12885 Re:What 900 RPM Sounds like 5 Years, 4 Months ago   No.   Logged       The administrator has disabled public write access. #550818 chromepony (User) There's no such thing as too much chrome Platinum Boarder Posts: 1902 Re:What 900 RPM Sounds like 5 Years, 4 Months ago   Too way kool !   Logged     ...I love the smell of smoked pork on a warm summer night!   The administrator has disabled public write access. #550819 jd750ace (User) Front toward enemy Platinum Boarder Posts: 18763 Re:What 900 RPM Sounds like 5 Years, 4 Months ago   DageonYar wrote: Ok...

Or does the unit take care of multiplying for you? The tool is set to two stroke or 4 stroke, and when set to 4-stroke it doubles the number for you automatically to account for 2 revolutions of the crank for each firing.   Logged       The administrator has disabled public write access. #550834 sswiss (User) Fresh Boarder Posts: 45 Re:What 900 RPM Sounds like 5 Years, 4 Months ago   This video and that EZ Tach would have been amazing references for when I was tuning my bike.
