What is the top tree bottoming out on if not the lip of the bearing nut? The RaceTech info specified 150mm as the measurement of the oil. That seemed a tad much but turned out to be about the same as the stock cc recommendation. Isn't the emulator taking up space? Gary...your 120mm seems more in line. How did you come up with that amount? I used a "plastic" toilet riser...measured down from the moulded washer 150mm and drilled a hole. Over filled the tubes then suctioned till drawing air.

Matt Wiley from RaceTech suggested 130 to 140mm. I thought "better to be too stiff at the bottom of the stroke than too soft" so I chose to use the 130 (more fluid) figure. It just takes a few minutes to make this adjustment and I will probably make this adjustment after the weekend. Whether 150mm or 120mm, it will always be close to the OE fluid volume of 15oz as every 10mm of height is only about 0.3 oz - so that 30mm swing is just under an ounce of fluid. But a 10mm height change makes a B I G difference at the bottom of the stroke.

The OEM spec is 75mm. That's a lot of oil. They were trying to do all they could to stiffen the OE solution.

Good solution on the oil extraction tool. Got a photo?

Havlo;  its a very easy thing to remove the top clamp with modded lower as the top.  crown nut, 2 pinch bolts.....Oh, yes...gauge cluster too.

Its all going to depend on your tolerance stack in the build.  Gary may be OK, but you might not be.  OR....you might be better than Gary too!

Gary:   why a washer between the cap and spring?  

My son and I just spent some time dialing in the suspension setting.

Here's where I'm at (and staying for the moment). I used the averaging method (without bounce and with bounce) to obtain these values. These numbers are with me in my riding gear with a full tank of fuel.

Forks
Free Sag (no rider) 15mm (7mm stiction)
Total Sag (rider) 35mm (3mm stiction)
Total Travel 75% at 140mm of gap

Shocks (preload collar set on 4 of 5)
Free Sag 10mm (5mm stiction)
Total Sag 39mm (2mm stiction)

Stiction is the delta between the bounce value and the no bounce. The stiction values are good. You want them below 10mm, the lower the better. These measurements were taken many times, and every time you get something a bit different. The numbers above are averages after my final adjustments.

The rear shock numbers need further research. I know that RYCA lists the rear suspension travel as 2", but I'm thinking that is the shock travel, not the travel from the end of the swingarm. My measurements are from the axle nut to a spot that my son liked on the license plate. The delta between fully extended and the total sag figure is about 1.5". I hope I'm not using 75% of the shock travel just sitting on the bike. I have a feeling that the actual suspension travel at the end of the swingarm is closer to 3". Even so...that's 50%.

Gary, you think the lower-to-upper triple mod could work with upright bars?  Might be able to drill new holes in it for the bar risers?  Mine is a tracker and yes, the front suspenders are bottoming duds as is.

Right I'll take a look at the machined Savage uppers. Also saw them on Dime City. Can't remember if they are made for standard bars. I love your fork mod. The only thing I don't love about my bike.  Mostly.

Thanks Dave, at first glance.  The other thing I was thinking of trying, but, am limited in my fork knowledge is sending my forks out to get progressive springs, have them and the fork tubes cut & take Ryca spacer out so that I get back to full travel, but, still be shortened in the stock triples.  Obviously not as effective at improving ride, but, certainly getting more travel.  Clearance would have to be checked.  I just don't want clipsons, I want upright bars for my dirt tracker look (and comfort haha).

The drill surface in the photos is my drill press.

The ground clearance is the same as the RYCA set up because the bike has the same stance.
