Hundreds of bikies are descending on Melbourne this weekend, but police have warned they will be watched closely amid fears of a brewing bikie war.

The Finks are having their annual national run with riders from across Australia gathering at the club's headquarters in Port Melbourne on Friday and Saturday.

Bikies are also expected to ride to Glenrowan, about 240km northeast of Melbourne, to meet other Finks members arriving from interstate.

But anti-bikie taskforce detectives have already warned senior members of the outlaw motorcycle club that there will be no tolerance for illegal behaviour.

"Local police members will closely monitor the rides and will take swift action to detect and disrupt any (gang) members who commit crimes, road safety or public order offences," a police spokeswoman said.

The Finks weekend run comes while a tense stand-off continues between the Bandidos and the Hells Angels.

Bandidos sergeant-at-arms Toby Mitchell was shot for the second time last week.

Two men linked to the Hells Angels have been questioned over the failed ambush.

Anti-bikie detectives have also raided 17 properties, seized drugs, cash, an explosive device and a stash of guns in the past few days.

At least seven people have been arrested in a bid to prevent the feud from escalating into an all-out war.

In Bendigo, the Satan's Soldiers clubhouse was also torched on Friday.

Police say the fire was deliberately lit.
