There is no fibre washer of any sort on the fiero head. The tappet adjustment cover has an O-ring but they will never bust and the leak will only come if you damaged the cover. The oil leak is from the surface between the cylinder head and the tappet cover. They are ideally sealed with 3-bond. Due to timely ageing of the engine, the adhesive gives way to let some oil pass out. So most mechs just apply some three-bond on the outer surface to get away. It would only hold untill the engine reaches operating temperature.
Also the cam window rubber is another place where the leak is found. Its no big deal...just remove the tappet cover, apply the three-bond again on the surface and bolt it back. Problem solved!

I wasn't sure about the fiber washer anyways. Killer had told me about the fiber washer when his Apache was leaking oil.


Use RTV silicone sealant (white) in place of threebond to stop oil leaks. RTV red is stronger and suited for higher temps but it will make it difficult to take apart the component later. White is enough.

Sometimes when the head is warped, the o-rings and gaskets will lost their sealing effect.

he is not complaning of a leaking head. just the tapet covers, where ppl usually put 3bond.

Thanks,

No issues Ramki. I am trying to know Fiero better.

I will be watching this thread closely as I too have some plans in mind.

Restoration:
1. 100/90 for the rear tyre
- Can i fit wider tyres without altering anything on the bike? I am ok to get some spacers on the shocks, but i am worried if the tyres start scraping the side frame.

2. A good seat
- The older seats have torn a little and i would rather replace it with a nice comfortable seat then put in those form cushion and another seat cover on top of it.

3. Mild mods to make it look sporty.

EDIT: Also planning disks on the front and self starter.

Even I have done only 37000 kms since I got the bike in 2000. Great to know that we are in the same boat.

Yes, you can fit 100/90 without changing the rim or getting spacers. I have got Dunlop Monster 100/90 tyre on the stock rim and the grip is good.

Shamil, how about installing a square section rear swing arm to the fiero? It would enhance the looks a lot. Fiero looks a bit odd from the side a slightly longer wheelbase would make the bike look proportionate in profile view.

That will enhance the looks for sure. Will it enhance the handling?

Do I need to look out for any specific brand/ material? Is it available from TVS?

Longer wheelbase = more stable. But you will lose some flickability.

You might be able to put one from the TVS range itself. I'm not accurate about the lengths of the swingarms. ZEN would be able to take care of this.

Well the tappet cover (or cam cover) bolts TO the head

[ramki067]

Can Zen Motors on Bull Temple Road solve the oil leak problem? I'm getting confused on what the real problem is!

Thanks,
Ramki.

Head warped usually means the surface that mates to the bore is warped. unless you meant something different.

Flickability is important for me, especially in bangalore chaos. Anyway, I will check with Zen. Thanks

Killer's bike had a never-ending compression leak complaint. Which I finally solved. I was too curious to solve it, that I personally stripped it one day before his track day and fixed it. There is no fibre part/washer in the head and I've been working on this engine since over 5 yrs now.
It was a leaking head gasket which always kept busting and letting the cylinder compression to sneek once the engine comes to operating temperature. The mechanic who kept installing his engine would always apply an adhesive on the head gasket and that would instantly melt away...making the coating on the head gasket to melt away and sealing is lost.

Cool

I wasn't able to follow up with this issue as i had relocated to Trivandrum by that time. Glad to know that it was solved before he sold the bike and bought the RTR.
