Title: oil leak
Post by: El__burro on November 25, 2015, 05:51:34 PM

good day, i am trying to get my bike ready for MOT.
I have several issue to sort out I guess an oil leak is quite important.
I have taken the bike out on several occasion around the block to see if oil level was good.
I have sorted the level but I have had oil spitting out from the hole where the tachometer would be inserted. (i don't mount a tacho so it is not blocked).
Can anyone suggest a solution to stop this leak that eventually ends up on the exhaust and gets the whole situation smokey.

thanks

You need a taco blanking plug

+1 on that. You will get one on eBay.

Forget eBay that was a bad call. But my favourite website has them for 15 dollars.

Or just put a new oil seal in

Dennis, you mean that by changing the seal and leaving it empty will stop the leak?
Thanks

It should do, buy a genuine Honda one, less than £2 from D.S.S.

As Hairygit said it will stop the leak, but it would be nice to cover up the hole to stop road salt water and other nasties from filling the hole, here is some more info

So from what I've just read, you took the seal from another rocker cover? Don't waste your time and effort hoping a seal of unknown age or previous use will fix your problem, could even make it worse! Just get a new one, better safe than sorry!

it came off a spare cover for the same model/year, it looks in good conditions.
I'll see if it leaks, if it does I'll get a brand new one.

Unfortunately also with the new washer it's leaking a bit. I was thinking I could use the tacho cable (is it?) to block the hole an blank it.
Has anyone tried this before?
Thanks

Surely you are bound to get a leak unless the hole is completely sealed in some way, by the cable or otherwise.
Saw this, at £10 it seems cheap enough and I reckon it should stop your leak.

thanks, i was thinking of doing it myself using the spare cable in the picture. Actually that could be not the rev but the speedo cable.
how can I tell?

thanks

Length is the obvious thing that springs to mind but not sure how different they are. I'd guess the speedo cable is longer.
If you fit a cable in the hole where will it go to? Surely a plug is a much neater and probably better solution as it will properly seal the hole.

The cable fits best with the speedo drive, in the tacho whole its a bit loose.
Anyway, i have contacted the (only?) seller for the blanking cap above but still waiting on an answer.

thanks
