Found an engine; it’s paid for and will be here in a week or so. Found a transaxle, too.

The brake discs are VERY heavy, 13lbs each for the fronts and 12lbs for the rears. This is due to going with larger vented rotors than solid discs. I had been assured that small solid disc brakes will be fine… so I may take these boat anchors back.

I saved the bombshell for last though it probably won’t be a big surprise to regular readers… I’m going to be selling Kimini.

On the front suspension, I’ve got a good design candidate, though it’ll have to wait for the front nose; only then can the inboard suspension points be fixed. Wouldn’t help to fix them now only to find the nose is in the way.

Regarding the sportbike shocks… the more I think it through the less likely they’re going to work due to the spring rate and shock travel.
With shock travel of 1.5″ (or 2″ if I shorten the bumpstop), the 595lb/inch spring rate’s probably going to be too low. This is what happens due to all the leverages involved and the short stroke. While the springs can be replaced with stiffer ones, the spring rates end up getting ridiculously high… a shame. It’s not a closed case yet, but if you feel they can work in your project, drop me an e-mail else they’ll end up back on Ebay. If that happens, I’m right back to where I was with Kimini, facing the purchase of $300-$500 shocks, ugh, this was supposed to be low budget. Eh, what I’ll do is specify a coil-over shock of common length. This will allow builders to go “economy” or “nuts”, as their budget allows.

Ordered the nosecone and brake rotors so that front suspension design can progress. The nosecone is for determining where the inboard front suspension pivots go. The brake discs are for measuring the thickness at the mounting face, as it shifts the wheel center outward. I feel better measuring them – and every other component – myself. The seats will probably be next.

I got a great deal on a Tilton hanging pedal set, but after seeing how compact, low, and light my brother’s floor-mount pedals are, I wonder if I should go that way. Than again, when I tried them I experienced what other people have said about floor-mounted pedals. The arc of the pedal and foot don’t match, lifting my foot off the floor. Not terrible, but something that would take some getting used to. I have to think about it.
