Rehabbing A Rebuilt '99 700 Triple - Dies w/Choke

[MURDER YAMAHA]

Yep, 8CR weights are your factory weights.
Good to hear it ran ok for you, and were able to enjoy it!

8300 is where peak power is stock, but it's a pretty broad peak and mine definitely seemed happier at 8500 than 8100.

@MURDER YAMAHA it was kick ass. Keep the old sled dream alive.

I ordered a set of adjustable weights that indicated they'd fit the 8mm pins on the primary with a 50g base weight, I'll play with it until we're in that 8500 range.... it's peaking at like, 9700 right now

The longer 151 track length might have something to do with it b/c I didn't swap gearing or the track drivers etc... I would think I'd feel that more as bogging down / loss of RPMs on those steeper hill climbs

Oof, I think I'll be under 50 on mine even after I get the rivets in. Is that the Thundershifts? They used to make lighter ones.

Lightest ones I could find that explicitly said they'd fit the 8mm pins for the primary but i'd order something else if y'all have a recommendation. They're the STM Supertip Trail Cam Arms.

9gr difference between them and current arms but I dont have a way to add weight and I'm way, way above the RPM goal. ....

Secondary position is 6/1 with a green spring, btw.

9700 RPM is nuts, I wonder when they go boom?

Update. The 50gr weights felt a little bit sluggish for power. But the Tach was topping out. So I began to suspect the tach itself. The dash pod is ported from a 1998 MM 700.... the original dash with the two separate round pods was trashed when I got the sled. So I grabbed one of those cheap "tiny tachs" from amazon that you wrap a little interference cable around a spark plug wire.

Turns out there is a pretty significant difference between that tach and the one in the dash. When the tiny tach reads ~1500 at idle the dash says 3500.

So now we get to try again and see what the tiny tach tells us

'Course now all of the dash pod indicators are suspect, lol. The fuel level, speedo, brights indicators all seem to work. I've never tried to trigger the water temp indicator or the oil level indicator lights.... i put new sensors in during the overhaul and have always treated it mostly nice. Not sure how I would test those realistically. Can I just unplug the clips and complete the circuit?

EDIT: Yes, you can short the sensor plugs and it will make the dash pod lights work. So everything but the Tach is happy. Now we just need to dial it in!
