over heating

[LONG-ROD]

I have a stock 250r cylinder with 310 sleeve bored to 67.5, I have inline coolers on the hoses, anyone know if those actually work, and is it nessecary for an over sized radiator for hard dune rideing or am I good with the stocker.

I ran a 310 but it was an aftermarket cylinder with a stock rad for a while with no problems. But the stock cylinder doesnt hold as much fluid as an aftermarket so you may want to look into getting a rad. If your interested i have an IMS rad that was run on a psi 425 and had no problems cooling.
