Replacing the o-ring on the pump helped a lot, it seems dry under the bike so far 🤞.

I think my engine can be reaching 100k miles (hard to say as it was originally from Swiss, then imported to Poland, then moved to UK). Even the best engines have their life limit, but hopefully it is not the case 😅. The o-ring is now replaced and at least the leak outside should be gone. I just need to do some more work (noises from the clutch) and it should be back on the road. The oil level was never dropping and once I think I noticed it went up, but it wasn't so obvious. I was not riding the bike too much in recent years though. I'm still looking for that oil pump mechanical seal and once I find it I'm going to replace it too. I'm also doing on the clutch now, will be putting a new/old clutch set. Any replaceable oil seals there I should look at while I'm doing it?

Hi! I'm seeing coolant level going down and a wet patch under the bike constantly. This has been for 2 years at least and finally I decided to do something about it. Last year I replaced o-ring #7, the big one on the water pump cover but it didn't help much. Recently I noticed the o-ring #21 on the water pump itself was not good (flat and old) so I will replace that. I wonder if the oil seal in the water pump is also replaceable as I don't see it on the list of parts and the water pump itself is not available anymore (and a bit costly even if it was available): https://www.fowlersparts.co.uk/parts/5053486/vfr750fn-1992-it/water-pump-vfr750flfmfnfp The seal: Now I'm worried that I have an oil leak actually and water mixes with the oil. The o-ring I'm going to replace n the water pump is causing that leak and it looks like oil: Sings of water in the oil: Is that really bad? Hope that's not head gasket. Any other seals I could replace? The service manual tells about oil pump mechanical seal? Where do I find that? Any suggestions more than welcome. Thanks!

Thanks, I just ordered a repair kit by Tourmax that includes the springs, cups and rollers. Edit: I fixed it! After fitting new springs, rollers and caps the problem is gone. The bike starts now every time without any issues.

Thanks for the help. I've removed the starter clutch and disassembled it. The clutch outer doesn't have any cracks but the roller seats are slightly worn. The springs are odd and looks suspicious.

Cover taken out, gears look OK I think, I'm guessing I need to get out the starter clutch to see what's inside. Can't see any cracks or problems yet.

Hi, I'm having a similar problem with starting my VFR750F from 1992. It used to happen very rarely for the starter clutch to not engage, sometimes I could hear some metallic noises. But it was always starting on the next spin so I didn't bother about it too much. Recently it got much worse even though I didn't use the bike last year. Just starting the engine once a week to keep it going. Today morning it did not engage the clutch and no metallic noises. I recorded it on the video below. After putting 1st gear and moving the bike slightly forward, it started without problems. Maybe it's not the clutch itself but some problems with gears on the starter motor? Thanks for any help.

Hi Grum, Thanks for the response and advice. Looks like good times are coming for my old lady as she will be getting now 99 octane E5 🤘. Already seen that E10 shit on the petrol station.

Hello, Any idea if my VFR750F from 1992 European version (probably originally from Swiss) can run on a E10 petrol? Currently I'm running on E5, but UK is going to replace it with E10 soon. I wonder if I need to start switching to high octane petrol instead. Thanks, Hubert

Thanks for much, that's very helpful. Cheers!

Hi, Has anyone an opinion on rear brake discs that are available on ebay under xarrow brand name that are for the half price of good brands like EBC? Not sure if this link will still work. Just found one and thinking about buying. I have NG discs in the front and I'm quite happy with them but I cannot find them in UK. Thanks, Hubert
