Just some maintenance

[Bezmozek]

So, after seeing pics of your bikes here, shame on me, because if it is not broken, don't fix it, there was nearly nothing to do on my FJ for last few years.
But all that FJ enthusiasm here on the forum seems to be contagious, I am going to try to get my bike in better shape.

I was forced to leave my bike outdoors last winter, so I have some rust issues to solve.
So I removed footpegs, grind out rust of and nickel plated all iron parts for now.

Exhaust is rusty too.
For silencers hopefully heat resistant colour will be enough, but collector is gone, rattled more and more, till 4th cyl intake felt off,
but some parcels are on the way and I hope to update this topic soon

I've bought some Italian high gloss black and it is holding pretty good on the exhaust. I even painted the brackets that hold the downpipes and they are still nice and shiny after some 1000 km. I'll post u a pic of a can if you want to look for it. VHT engine enamel doesn't hold (even on the mufflers).

..... VHT engine enamel doesn't hold (even on the mufflers).

Balky, the engine enamel is only made for engines and is bullet proof in that application. If you want exhaust paint though, VHT make a very high temp coating for just that.

I know, I just said what I tried so that he doesn't make the same mistake.   
On VHT's site, I didn't see high gloss high temp black. Something I managed to find locally (made in Italy). As for VHT I did see an option of glossy high temp clear coat.

Finally I had time, to fit new collector and downpipes. UK made by blackwidiwexhausts
Silencers still OEM, but looking for some decent and quiet slip-on upgrade  

[HydroDog]

F-me Running! I think I just took out 3 rabbits looking at those pipes!! Beautiful!!!

[balky1]

Yep, fantastic!

What is your experience with the exhaust considering the fitment? No problems to bolt it on?
Just a remark, did you change those gaskets at the head ports also? They are supposed to get crushed when you tighten the downpipes so when you fiddle with them it is possible they won't seal properly.

[Urban_Legend]

I really like the look of them. I am looking at getting another 84 and these would look sweet on it.

[Bezmozek]

Fitment was easy, except that thread on bolts on head is way short, and flanges are flat compared to OEM, so MANY spacers needed:
.
I will buy two sets of SS spacers with different outside diameters and make fake ribbing on bolts, to dissolve heat as much as possible.
Anyway it is beautiful piece of steel, was worried about noise as there is no space for gas to expand, but nearly same as with OEM collector.
Kit came with all gaskets needed, so I changed all of them, only pain was to extract old ones after all those years 

I also repainted belly pan, hopefully there will be no issue as these downpipes look to me bit more forth than OEM ones.

Will update

Be sure to wipe those beauties down with alcohol or lacquer thinner to get all your finger prints off.

If you don't, when you heat those pipes up, all those finger prints will magically appear.

Nice job Stepan....

The later models used a flanged nut. 

Just swap to those.

[racerrad8]

Yes they did, they can be found here. Yamaha Steel Header Lock Nut

[Bezmozek]

Thanks, but flanged nut does not help. Thread on stud is not long enough to tighten flanges close enough to head to seal. There is 11mm gap.
At the moment, I do not want to wait for fabricating such high SS spacers, maybe will change in future 

[Urban_Legend]

I would recommend getting somenew exhaust studs to meet your needs. Would be much better than spacers, and the existing ones are looking their age.

I've got the identical exhaust and I signed.ply went to zettlers and purchased stainless steel nuts and lock washers.i double nutted the studs haven't looked at all I check periodically.
