Sag numbers

Guys today I was working on setting the SAG on the H2 and I was able to achieve the 28 mm in the rear however I couldnít get any more than 20 out of the front adjusters all the way out. With gear Iím probably 195. What are you guys seeing? Iím wondering if the front spring rate might be too much for my weight. Iím trying to quicken the left and right transitions and Iíve ordered a set of the Brocks links for the rear so I can raise the rear up about 5 to 8 mm which should absolutely help with the turn in but I wanted to play with the SAG numbers today and see what I had.

No one’s measuring their sag numbers?

I've done it but I don't recall the numbers. But ... a couple of winters ago, I gave the bike to a local suspension guru over the winter, Accelerated Technologies, * (website currently down) - "Too harsh. Fix this". I know he had the forks apart and revalved them. So, what's in mine might not reflect what came stock ...

Also, I know that a major change to rear spring rate was made, in the interest of stopping the shock from bottoming.

All I've done so far with the stock suspension is set sag and some rebound using the Dave Moss suspension videos.

I've got the numbers at home (not there at the moment), but the rear preload sag was around 25mm, front 35mm if I recall correctly, will check. It did make a difference and I think helped the rear to have a better wear pattern when on the track recently (along with better track set tyre pressures).

I'm around 100kg+ in my gear. I haven't noticed any bottoming out of the suspension, though my next track ride is for 3 days at Phillip Island in early December. I think I'll put zip ties on the front forks to check travel this time.

I have toyed with the idea of upgrading the internals at least on the forks, and maybe an Ohlins on the rear, but to be honest with my riding being mostly road based with occasional track days, I may be investing in something that I won't get the full use out of, not sure.

Slowly getting there!

Yeah I couldn't get the travel out of the front forks. Like I said with the pre load all the way out the best I could get was 20mm. the rear was no problem. Would love to add Ohlin's but it doesn't make any sense for the amount I ride her. I'm going to add the Brocks links and raise the rear 5 to 6mm and try that. Hoping it quickens up the transitions.

Before doing any of that remove the dust seals and add some grease. Forks could be sticking, seals could be in slightly off not seated flush, or even the axle could be slightly misaligned. Doesn't sound like it's being wheelied all over town so don't believe it's a bent axle.

Forks sticking.... I don't know on that one. She has 5,000 miles on her. I've never heard that before. I'm sure anything is possible though. Maybe the front axle nut could be too tight and slowing the action down. its a far stretch though.

Haven't seen anyone posting here in your weight range having the same issue. Could be they just decided not post about it but doesn't it seem unusual.
