Oil pump drive chain / + camshaft

Hi guys, bit of advice wanted, just been doing tappets oil change etc and had clutch cover off for slight oil leak. I notice that the oil pump drive chain is quite slack, I can find nothing in w/s manual to help me so is there anybody out there who can tell me what limits are with the oil pump chain. VF1000ff 1987 btw and anybody got a good exhaust camshaft as my front one is slightly pitted, not bad but will change if i can get a better one. Cheers guys in anticipation…

Slack oil pump chain is normal; the chain seems loose on all my VF, on the near new 20 000 miles R as well as on the 85 000 miles VF/G… Sorry, no good cams left in the shed but I’m gonna regrind some one day.

hi roger, as fred says they are all slack, they often look like they could do with a half link in the chain,

When I overhauled a R engine to be assembled in my Bol d’Or, I changed pump chain too, and there was no big difference between new and old one, slack is still there.

Thanks guys, think I will leave it…
