Easy fork upgrade

[Triple Trouble]

I've finally got the details ironed out for a fork upgrade. This info is courtesy of Wayne Tripp and I'm just passing along the information. The first is a very simple spacer which is placed under the spring and helps control the damping. You need to cut the top pre-load tube by the same amount as the spacer length. The second variation should be self explanatory. Following is from Wayne:

"We have since machined a few "spacers" that tighten up the clearances on the bottoming cone piston a bit more than just using thick walled tubing. This improves the dampening even more. NO, I do not want to make more, but the details are below.


1.) Easy and cheap - 1.5 in. OD tubing, .200 wall thickness, 1.575 in long.
OR,
2.) Machined for closer clearances - 1.522 OD, .955 ID, 1.575 long. - add .125 in wide by .050 deep slot along outside.


Place on top of bottoming cone (underneath spring), and cut 1.575 inches from pre-load tube above spring. Cut less if more pre-load is desired. If using Progressive springs, you will need to cut for the pre-load in addition to what Progressive recommends for the spring used.

You done it yet? & if so how's the ride?:smile:

 

[Triple Trouble]

Not yet but it's in the plans before the snow goes. When I first talked to Wayne about this he said there is a rough bend near his shop that could be negotiated at about 15 mph because of the bumpiness and after the plain spacers were installed it was possible to go 30 mph. If this works maybe you can get both knees down?

No change in oil spec mentioned, so assume use Triumph reco?

 

[Triple Trouble]

I was wondering the same thing. Others have tried heavier oil with success but this controls the flow acting as a valve so heavier oil might be too much. I'll try and clarify that.

 

[Triple Trouble]

Wayne suggests keeping with 5 wt oil unless you are heavier or ride really aggressively then go with 10 wt. Preference is Belray HV1 in either weight.

Watching this with interest.

Watching this with interest.

Me too.

I'm definitely going to try this using the smaller clearance spacers but it will be another 6 weeks minimum before the snow has gone and the roads are clear of salt and sand.

I wll have to contact Wayne and see if I can get more difinitive information as this sounds a lot cheaper the the traxion dynamics route. I doubt I would know how to adjust the dampening of the traxion dynamics right anyway. Of course Todd has had them for quite a while and might have some pointers for me.
