I know I will need springs because adjusting preload will cause no static sag before I achieve proper race sag. I want to ride the bike some before sending suspension off. My question is.... if I crank down the shock to get close to proper race sag will that exaggerate the forks springs being too soft since you can not adjust preload on forks? Will the geometry be way out of balance and cause the bike to handle poorly?

I wouldn't try to crank it down. I'm in a similar boat (I weight 220 right now) and the suspension is overall way too soft all over (making it feel harsh). I would say just try to get the sag under 110mm and ride it. Mine is around 108 right now, and any further it's going to start handling like garbage. However, I'm a C class slow guy so.... lol

Springs? with an S?

Preload on forks?

From the composition of the quoted text above please just send your suspension to a professional.

Springs plural since there are multiple springs. I’m talking front and back. The reference to no preload on forks springs was to see how the effect of adjusting the rear out of normal range would effect the front since there is no adjustability. The rear will ride higher in the stroke but no way to compensate on the front end.

I would just ride it with less preload so it's more balanced. Get about 25mm of free sag and just play with clickers. If the back is riding low crank up the high speed.

Thanks for the response. That was the type of info I was looking for.

Just order the correct springs. You’ll need them anyway. On my 450, I was able to get it close enough to how I wanted it just installing the correct springs and raising the fork oil level by 10ccs. I make clicker adjustments based on the track I’m riding at the time. If you try it with the correct springs, you might save yourself the expense of a revalve.

Stiffen the high speed compression, I adjust mine 1/4 turn and sag changes 5 mm
Yes the front will dive low in the stroke need the correct springs
