Polaris P-85 on a 78 SRX ??

[Blisteringsnorider]

I know they do this, but my question is what bore length do you use for a 1978 SRX ?? Shallow, Medium, Long ?? I know it's a 30MM with a 1:10 Bore
Thanks for any help

im not sure i can help as i don't know srx's but 87 exciters guys use a deep bore p-85 from a 87 and newer Polaris, 400,440,500,etc liquid cooled Indy with a Fuji motor . 30mm 1:10 taper its my understanding fan cooled are diffrent, maybe libery motors??????

I know the triple motors are different than the twins..... not about the Fuji vs Liberty

yes. the triples are 33mm not sure about taper.
