selling a LRD 300mx kit built and ported by arlan in 2004 LRD # 26570604.
It is a 89 style stock cylinder with the works don to it. *must run race gas* has over 220 lbs of compression.
Fresh bore and woosner 72.45mm piston with around 6hrs run time.
Arlan dynoed it at 54hp last summer at his new shop LED.
It uses a O-Ring head gasket set up like the pro cross cylinders and copper crush washers as well.
comes with all needed 0-rings and washers as well as 2 spacer plates so it can be run on a long rod 87-9 style or a short rod 85-86 style.
Why the 2 spacer plates? well thats just the way arlan did it to get the port timing and Head work to preform the way it dose.
This is off my friends quad he went to a LED CPI sphinx 350
This set up is ready to run and works awesome!
$325 shipped any where in the lower 48
