Hi Todd. Do you think it possible to install the under piston spray jets from an 4 valve engine into a 2 valve block ??Results of a low speed tip over with a 2015 Griso below, taken apart in my shop today. Visual valve cover impact was minimal. Cylinder studs bent and caused excessive wear on the piston... took out the rod/crank bearings and crank journal. Put crash-bars on folks.

Ghezzi did it with internal plumbing (which led to the factory finally doing it rumor has it), so with a handful of work, answer is yes.Hi Todd. Do you think it possible to install the under piston spray jets from an 4 valve engine into a 2 valve block ??
265,000 miles? Damn that's amazing....and still going in the 01.5. Unreal, gotta love the 8V.Worthy of note to those reading this (and despite the many that will want to debate me on it)... I have been involved with several major engine failures over the last 10 years (mostly on 1100-2V motors), where piston/rings/cylinder destroy themselves due to cylinder studs being bent from everything from parking lot tip-overs to moving falls. This drops tons of metal into the bottom end and trashes the motor. Yes it can be rebuilt, but easier to replace the motor in this instance.
I'm not posting this to scare anyone, but it is worth the time to inspect everything from even the most minor falls; Pull and check the studs as a minimum, and on the 8V motors, valve gear since the valve covers are bolted to them. Most of the time you will likely be OK, but it has shown to be prohibitively costly if things go south.
I have a 2015 Griso 1200-8V right now that likely fell victim to this. I will post info as it comes apart.
Crash-bars are cheap insurance IMO, and I run them on all of my bikes that can easily accept them.
All said, my first Guzzi had been down a few times (minimal impact to the valve covers only), and it made it 265k miles. The motor was still running great when I pulled it out to build it into GTM-01.5.
Me thinks that's Todds old Jackal, no? Should be a story in itself.265,000 miles? Damn that's amazing....and still going in the 01.5. Unreal, gotta love the 8V.

Yes, the 265k was on the 1100-2V motor(s), ~165k on the stock engine, which was still running strong when I replaced it with a modded V11 Sport motor; Which had ~100k on it when I converted it to GTM-01.5, now powered by the 1200-2V motor.Me thinks that's Todds old Jackal, no?

I look at my Jackal, and the hacksaw hanging on the wall with un-pure thoughts going through my head!
