GSXR 1000 Buggy: Black Beast Revival

Mark and I learned a hard lesson with the '08 GSXR 1000 platform. We starved rod bearing #4 3x in 2 different motors. From our research this is caused by oil starvation due to our use of the engine in a flat track style car. The oil slosh caused by the cornering forces must have caused a drop in pressure and damaged the motors. Back to the reliable '03 750 that never let us down! Follow along as we renew and refurbish our Protolite parts and prepare these buggies for a hill climb event!

Sweet stuff

[@OversteerEngineer]

Both of your buggies are superb 🔥 Its been cool seeing them evolve. Any Idea on how to solve the oil starvation problem without a dry sump? I’m building a crosskart with a gsxr1000 k7 which is the same as k8 if I’m not mistaken. I know that the guys here in Sweden that race crosskarts put more oil in their engines. But they run 600 and 750 engines.

There are definitely solutions out there, we just decided to revert to what we know works. We also had a Gen 1 Busa in a sand rail that never did this, so that’s the power plant we will probably end up with. There’s plenty of companies that make modded oil pans for circle track sprint cars! Yoshimura even has one for the newer GSXR1000, there’s plenty of options for older years too. We also recommend adding an oil pressure gauge somewhere. The 1000 has the external cooler; ideal place for inline gauge. We never saw the oil light on the dash, but it definitely starved bearing #4 consistently. www.yoshimura-rd.com/products/gsx-r1000-17-21-mod-lite-billet-oil-pan

@@AndyShear didn’t know about those oil pans, I’ll look in to it. An oil pressure sensor with a really bright warning light might be enough for me. Thanks!

What those rear shocks from

[@AndyShear]

RZR XP 1000, they’re Walker Evan’s. Really nice shocks. Picked up all 4 used for a good deal, there’s plenty of these out there!

@@AndyShear great 👍
