dyno numbers from my 340 just for reference

went out to wipe it off again before i go to the cruise in i think i may have found my heat issue popped hood was doing a once over looked at the rad the cap its leaking slightly.
the rad does not have a whole i can see and it was not pissing from any holes under pressure but i did have fluild around the filler neck and theres a hint of rusty loooking residue on the cap like dryed water would do and some spots running down front of tank sense it has that open area for it to run off at
had a second cap not sure how old it was going to pick a new one up when im out and give that a shoot
