Have you decided for sure to restore the bike? I've also seen some posts you made about buying a different bike with the insurance proceeds. If I was in your position, I would buy another running K75s and strip the crashed one: keep some spare parts and sell others. If your tires are still good, that's worth $100 already...


My biggest concern for you is the forks. You mentioned they were stuck. If the fork tubes are bent, it will expensive to replace. Then you have to wonder if the frame has bent, even a little.

I think the results of tomorrow's appraisal will make up my mind... With the bike fully stripped of problem parts and a few I discovered like a cracked airbox top sealed w duct tape .
the price of used replacements paint and materials is more than the payout.  I may walk away from all the fiberglass work u less the salvage quote is very low...the compressed forks suggest a disassembly roll on a flat table and reseal would be prudent with a pros assessment of the springs.  Nobody commented how struts can lock down collapsed like that...worrisome

I'll take on that task. :giggles Maybe the severe impact created vacuum and friction enough to hold them in compression until jarring them created the release. I wouldn't worry about them. If I had money enough to get a different bike, I'd get rid of them unless I wanted to build my mechanical and troubleshooting skill more than ride. Start negotiating with Gryph. He's been making room in his garage for just such an acquisition. :yes

Still grinning from my read of the "what I did to my brick today" post as I type. " Just when I thought I was going to get out, the pulled me back in"'


It's true Ive been seriously considering what most reviews site as best ST....the Honda ST 1300 but the pull of the Motobrick family is there to be sure... Thanks, ive been difficult to live with since Wednesday and grinning rare.


btw Laitch im still numbplussed, not nonplussed....a little Jonny, a little high brow.. I give my self a +1 for my perfect typo descriptor of how I feel..


Appraiser in an hour, time to pick up my tools and clean up.


Here's gone_ape's info about suspension preload from the other thread.. I match his 200 ish # so I'll look this over..

[/size]___________
[/size]RCG, Glad you're ok....speed wobbles are my least favorite "fruit-of-the-loom-mandatory change" moments. [/size]Just curious....have you checked your suspension sag...static and loaded?  Fork Preload CAN be changed by swapping  top of spring spacers in the forks....some use PVC, but  I've found the Chrome plated brass 12 inch long 1 1/4" Bathroom sink drain Tailpiece  pipe (at Lowes/Home Depot/Ace hardware etc...) to be almost an exact diameter to the original and you can cut it to size to give you the sag you need. I'm 200 lbs w/o gear and the standard 10mm of preload was too soft....bottoming occasionally.... I ended up with 25 mm of preload and am happy with that/any more and I'd be going to a heavier front fork spring--also using the BMW 10w fork oil at the recommended volume for my type fork (Showa), which is 410cc drain/fill and 420cc diassembled......then turn your attention to the rear shock preload and adjust as well for sag.......There's some helpful info here:    http://www.ibmwr.org/ktech/fork-oil.shtml
Fork Oil Quantities/Capacities Model            Leg      Change       Disassemble K75 Showa                                                  L        410 cc        420 cc K75 Showa                                                  R        410 cc        420 cc K75 BMW                                                     L        330 cc K75 BMW                                                     R        330 cc K75 Sport                                                    L        280 cc K75 Sport                                                    R        280 cc (Has an "S" stamped on the aluminum plug on top of the leg.)

forks and frame seem ok, engine starts and shifts... Im with Gryph on the salvage value, but decline your kind offer...Wifey may claim the money prize from the insurance claim but the brick remains my prize.   


I know I need a trans spline lube and I know I will do the clutch disc. Ive read those posts and have parts lists started. so the trans will come out soon  as that's where I'll have to start before reassembly.  Now may be the time to assess compression etc. but from the way she accelerates that's not an immediate problem.  Ill chech the valves .




I'll be upside down when im done but my spring rides will be glorious.  I need to reread the fibron repair posts as I have plenty of that to do.. my repairs last year held up other than with 500# at 5 or 10g Bricks wo fairings are...bricks.. but what a tank like shape when stripped.

Appraiser came and made a generous $300 salvage value offer.  I'll restore it.  Now back to work tomorrow...
