Cooling wasn’t really one of my issues, other than trying to contain warpage. My Miller Dynasty 200DX AC TIG and air-cooled torch would not generate the heat needed for proper aluminum welds on my RCR. I had to add supplemental heat with MAP gas torch.
It would have been interesting had the balljoint pin been factory offset a few millimeters so that rotating the housing would allow caster/camber fine tuning…. I have seen something like that on some replacement balljoints for 4wd vehicles..
Chuck, your work here and on anything else you’ve shared with us, is absolutely top notch!
Are you still working (you know - that job thing) ?
I try to not over-comment on builds, but rest assured I consume every post and appreciate them a lot!
You better get lots and lots of practice on the same thickness and alloy aluminum before you attack that chassis with a welder like that. I’ve been welding for over 50 years and I don’t think I would be comfortable taking a spool gun to the RCR chassis without a ton of practice first…
You can powder coat JB Weld - I’ve done it….
Another option is to buy aluminum or brass pipe plugs, drill and tap the holes - JBWeld on the threads, grind down the excess..
For street use, I think a good full synthetic 10w30 would be just fine. 15w40 full synthetic would be my likely choice for any sort of endurance or competition..
If it is a flat tappet camshaft and followers, I’d get some extra ZDDP (Zinc) in there Regardless of use (street or track).
Quite true, the coils will overheat and burn up windings when on their side.
I thought that the GT‘s used epoxy filled coils that can be in any orientation..
I would think that. You could insulate that tank from much of that heat - plus the airflow through the nostrils should assist as well. On the Valkyrie, there’s not a lot of options as midship placement would be in the passenger compartment, and not a whole lot of room in the back as I recall.
#1 is the Bobbin Slide where the front clip is supposed to be mounted. The bobbins are to be mounted on either side of the front chassis. Those holes in front of your overflow reservoir are probably the bobbin mounting holes.
#2 looks like it may be a vent for the fuel tank.
My iPhone 14 Pro has built-in Satellite connectivity for emergency use off the grid. I am frequently deep in the desert mountains of Arizona and while I’ve not had to use the service yet, it’s comforting to know it’s there.
