I know someone in Australia who does a Showa fork internal upgrade for the F800GS ... but it costs AUS$2,300 !

He has a set of Husqvarna Shivers I bought ... but they are going into my XChallenge. I'm tempted to get him to make a set of spacers to reduce the travel of the XC fork cartridges and put them into the 800 to see what happens. Stock the XC forks (which most people don't seem to like much!) are heaps better than the 800GS. The biggest fault with the 800 forks is they have no bottoming circuit ... so you use up the travel and they just keep compressing until ... crash!

Dead in the water right now - big projects at work, moving to a new apartment, blah blah. Gotta get the time // courage to pull the fork off and take it into the shop - hopefully within the next month.

After a short trail ride today, this has just jumped pretty high up on my list. Damn that fork bottoms out super fast!! Feels great throughout most riding, then you hit about a 2" square bump and BAM that's a hard hit!

That is the limitation of a "pumping member" fork.

Picture a round cylandar with a hole in the bottom. Inside the cylandar is a plunger attached to the rod. The hole is all the valving the pumping member has. So when you push it hard on a square edge bump you max the hydrolic force and bam!!

Agreed! Looking forward to getting the dampers in. If I didn't have to machine the legs it would be done already!

Machining...

Epicx, do you already have the place picked out where you'll have the machining done on the stock feet when you decide to take the leap? I recall one of the posts on the original thread mentioning that there was a shop out west who did most of the grunt work for the original job, but it would be a fortune to ship all the way out to Utah or Arizona (or wherever it was) from New England, to say nothing of the added time as riding season approaches.

I'll probably have it done at the machine shop at work, not sure yet. Ive been too busy riding but after some hard days off road this really needs to happen.

Any good machine shop should be able to handle it.

Ok, I spoke to the machinist at work and it looks like we might get to this on Saturday. Before I jump feet first, I want to gather some details from all who have done this:

*Did you all have the 40mm spacer put in place? If so, where exactly does it get installed in the damper? I looked at that photo but I don't see how it gets locked in place. Making the spacer is no problem, but if anyone runs without one I'd be interested to hear about it.

*What oil are you running? I'm thinking I'll run 10wt with the RXV Valving because I don't have a tuner to go to yet.

*Also planning on running the RXV springs that it came with. Need to determine what the actual rate is still but assuming it will be better than the stock ones.

*Did you replace the seals? This thing only has 3k miles on it, not much dirt. I'm thinking they should be fine but looking for opinions :)

Anything I'm forgetting? I'm shipping this bike to the left coast in about a month for a long trip so I'm trying to get this done ASAP but don't want to mess things up :)

Factory Connection

Just out of interest, have you considered the guys at Factory Connection for doing the tuning? They're right there in Barrington, New Hampshire, and advertise on their site that they'll revalve and tune to rider spec with only about a three day turn-around.

Called these guys yesterday, now just waiting to hear if they want to take on the job or not. Either way I'll be doing the machining...

The spacer my fork guru used was a spring. Small 40mm as a top out sping. I think it just sits on the rod and when it maxes out it is there.

Running Maxima 10 wt. Run whatever you like but always use the same oil each change or when changing weights use same brand. Why.... b/c fork oil is not very consistent and one companies 5 wt may be another companies 10wt or 15 wt.

The Aprilia springs come in two different stiffnesses. Check AF1's website and they will show them for sale as regular and stiffer or somethng like that. Mine came with the stiffer springs. I'm guessing there must be a marking on them to tell which is which so maybe email AF1 or call them and ask. They are pretty helpful dudes.

My seals were good. You have to be careful when taking them apart. Since you have 4 seals between the two sets of forks my guess is you should have two good ones.

What news?!

Has anyone else done this conversion aside from -W-, Gangplank, and EpicX? Does anyone know if EpicXRider is even still alive?! Will we find the answers to these questions and more in next week's exciting episode? I choose to think that the reason he hasn't updated the post is that the conversion was so successful he's scarcely been off of his bike all summer.

The time approaches for me to finally drop coin on my own F8, and though I'm certain about the purchase, the more I read about the horrendous brake dive (to say nothing of the off-road issues) perpetrated by the front suspension, the more I'm convinced this is a practical necessity for any real riding in the places I want to go.
