Tweakin: Thanks Amigo, I think she's starting to shape up!
DP9: Haha....not so well up front at the moment. I've ridden bike slammed this hard with this little front travel, it's.....not horrible....within the scope of what you can do on a bike like this but...no, I'll be working on more front end. It looks as though the 450 sliders are a bit shorter (1") so if I run without the dust boots I *should* be able to eek out right around 3" total as I'll likely raise it an inch from where it is now. I'll run oiled felt rope tucked into the fork tops, works well for keeping dust and crud off the seal you just have to clean it once in a while. I'd love to find some 4" fork boots that won't look smashed but I don't see that happening.
The other suspension change I'm planning for is a swap to an XS650 swingarm. It'll slot right in and will give another 2" wheelbase out back which I think suits this bike. The other thing that'll facilitate is running some neat old eye-eye adjustable Koni shocks I have. They're rebuilt though they need some sprucing up, but they'll bolt in with the 650 arm and won't need to be shortened. Plus they are for a much heavier xs750/850 and the damping is adjustable so in theory is should ride pretty well. I like'm pretty heavily damped anyway and these are neat shocks. The added wheelbase should support the long and low look.
With ~3" up front and it looks like a similar amount of travel out back I'll shoot for 1/2" to 1" of sag and that'll leave 2" of heavily damped travel to deal with what this bike will be presented.
The other change I'm considering....and I really am......is chopping the back off the frame. Specifically, the seat frame portion. I like suspension so I wouldn't be getting ride of that, but.....the seating solutions are kinda bugging me. What I'm thinking about is bending up(or having it done by a pro) a top seat look that follows the shape of a leaf or basically a solo seat with the lowers curved so they meat the swingarm pivot plates then curve up gracefully under the back of the seat to end in some sculpted shock mounts. A seat pan could then be shaped to drop onto that that would have the upholstery on it.
The other possible setup would be simpler, I'd have some tubing bent up in a loop like the rear portion of an Enfield frame with similar interesting rear shock mounts. I'd simply make the top rails angled down such that I could mount a fairly common solo seat without looking like some doofus just parked it on top of flat rails.
In the short term though, the build will go on as is. I have a couple other titled frames so I can tinker on the heavy mods on one of those and transfer everything over when the time is right. In the meantime I still have to turn up a sprocket adapter and source a bearing, make some spacers so the rear wheel aligns etc., on top of everything else it adds up to a mountain of work still needing to be done.
