Thanks guys
I'm currently running prog.springs in front and will be adding intiminators for a better ride...Bike has done roughly around 10000miles.
Should I get Type B or SE oil or get an Amsoil 10W50 (AMSOIL suggested to me by a vendor)
which one is better?

As always your inputs are much appreciated

With the Intiminators, get a good quality 10wt fork oil, like Amsoil Shock Therapy Medium (which is 10wt).

Do not use the 10w50 you mentioned a couple of times, this is motor oil as stated above, it's for your engine, not your forks!!

My preference is a hevier spring with lighter oil. Heavier oil slows the suspension down and though it may keep you from bottoming out over a small bump it will still not make up for an undersprung bike. Going with a heavier spring will keep your bike from nosediving any time you get on the brakes or enter a turn with any speed. That is something that heavy oil will not do. Keeping a lighter oil allows the suspension to work and keeps the tire on the road which in turn improves handling.

Completely agree here.
My next configuration is Belray 7W High Perf fork oil with my progressive springs with a 1/2 or 3/4" preload, from all the other combos I have tried I think this one should be the sweet ticket.

OK, so the quick fix is heavier oil but the true fix is heavier springs with standard factory oil.

So any idea what springs will run for an FLD? I know mrnone has some progressives on his front AND back but wasn't sure of price point as he was part of a development program. The stock rear shocks I'm totally fine with, it's just the front that needs attention. Why the F*** hd doesn't just do it right the first time on something as critical as a front end is a constant irritation to me. But i know, welcome to the club...

Progressive does not list a spring kit for the FLD yet, so can't really give any first hand advice on other brands.
As for HD, there is nothing "wrong" with the stock front end for 95% of riders, so no "need" for HD to change it. Not possible to build the perfect bike for everyone, so they pick happy mediums and allow the aftermarket industry to earn the dollars of those of us that wish to push the limits.

Look at (Works) front springs. Price is right.
I have the triple rated springs that handle anything I can throw at them.
normally ride on the 30 then when you brake your into the 40 and then 60, those unexpected bumps and holes that show up. Well you just need to steer through it cause the bike will handle it.

I researched progressives too prior to posting and saw nothing yet either.
I don't think I'm doing or asking anything unusual of the bike. I'm only 6' 210 and just ride it, basically. I push it at times, like we all do I think, but under normal conditions like running on a concrete freeway that is in relatively good shape and I hear metal on metal while going over a medium bump, well it pisses me off. I think it should be able to handle that. Oh well, I'll try the heavier oil and then look into springs when they come out. Thanks for the input bud, I always appreciate your posts as you pretty much tell it like it is and how you see it. Take care and happy new year.
