PSI GENESIS 750 Triple (Polaris 600/650) Motor, Carbs, Pipes, Ignition
Vintage PSI Genesis 750 triple, not assembled.
Carbs, Ignition & Pipes included in sale.
The Good;
Motor ran great before teardown for piston/ring replacement. Motor was last used in late 1990's on 1/4 mile asphalt in laydown chassis. This is PSI's Mod version with high compression race fuel heads and open mod 9200 rpm side exit hand rolled pipes. Carbs are PSI modded Mikuni VM 44's with all the brass. Ignition is stock Polaris.
The Bad;
Top end is removed, bottom end is assembled. Gasket kit is needed, cylinder liners are in excellent condition BUT need to be honed or bored to next size. (Nikasil coating is an option if willing to spend the cash)
I have (3) NEW Wiseco Polaris 488/500 Pistons for this motor, 73.00mm. For the record, the Polaris 488/500 piston is an exact match to replace the PSI custom pistons EXCEPT for one minor issue. 600/650's use thrust washers on the small end of rod and 488/500's use large end thrust washers. With that said any competent machinest can modify the Wiseco 488/500 wrist pin area to accept the 600/650 small end thrust washer side clearence.
Cooling rail is modified, this was quick connect cool down without belt driven water pump.

$1000.00 USD, open to shipping or pickup options (Due to size and weight I'd like to keep to the lower 48 if possible)
