Delkevic Slip on Review

[ribbert]

What rear brake is this ? 

Mid 90's FZR600R

Noel

Yes

Noel

....and how is it anchored?  Did you weld a tab on your swing arm?

[FJools]

I'll be able to make comments on the Delkevic Collector system soon. Have just removed the Staintune system and was surprised hoe easily it came off.
I did notice the RH rear silencer hanger frame  bracket has had a belt and will need straightening - that might explain the slightly odd/uncomfortable right boot feeling ??

[FJools]

Today I fitted the Delkevic 4 - 2 down pipes and collector box to my 92 FJ1200.

I took a few photos of areas that might need some work for it to fit with the lower fairing.

Re use of the original centre mount bushes, exhaust header collars and nuts is required. It is supplied with new copper ring type gaskets. I held these it place with a ring of high temp RTV applied to the inner side.

First off I fitted the down pipes into the collector box. They come with nice graphite bushes and the clamps on the collector box look to be good quality items - not your average hose clip. There are also 2 larger graphite sealing bushes for the silencer connections. (I haven't fitted the silencers (Staintune items) on yet as I'm waiting for some adjustable dog bones to arrive for the relay arm, after the Thunderace conversion.

Initially, fitment was a bit of a juggling act and would be much easier with two people, I couldn't get the collector box to seat up at the back mount.
This was caused by the heat shields on either side fouling the rear lower fairing brackets.


These were removed and then it was a case of manipulating everything into place, starting the bottom mount bolt then tightening the header nuts  to seat all 4 pipes then tightening the bottom bolt and finally the 4 clamps on the collector box that hold the headers.

I then re fitted the heat shields. The LH side went on with no problem, but the RH side one still fouled the bracket and I cut a section out for clearance.


I'm not sure whether these heat shield will interfere with the lower fairing yet and I'll be checking that tomorrow, all being well.

All in all relatively easy to fit and gets my thumbs up for quality too.

From the photo, it looks like they could interfere with the belly pan but even if they don't you might want to give the cut out a bit more clearance to stop any vibration transferring to the frame.

You can also get those gaskets to stay in place by squashing them ever so slightly out of round in you hand.

I fitted the belly pan yesterday, and it just required some stand offs at the rear mount. Not a bad thing in itself as it keeps the plastic off the exhaust.

That's a good bit of lateral thinking. The system looks great, what sort of cans are you fitting to it?

Noel

[FJools]

Hi Noel,

I'll be fitting the Staintune cans for now. I like them, they don't interfere with jetting and are a reasonable sounding pipe.

I'm just contemplating whether to trust the welded temporary dog bones and take it for a spin around the block.

Hi Noel,

You obviously know how to weld and that is as good as a butt join gets, but............ it's still a butt join!
It's a very good weld and if were me, I'd take it for a spin, just avoid any big pot holes.

Do you have the Staintunes with removeable or fixed baffle?
Did you give that heatshield a whisker more clearance of the belly pan mounting tab?

Looking Good!

I do wonder if it might drag under exuberant cornering loads.

Just a thought.

Noel,

thanks, I'm self taught and I was pretty chuffed with that effort especially as it was just my stick welder !
I think its a confidence thing with welding, once you get the knack it gets easier with better results.

I made up a jig with M12 bolts that held both ends at the correct distance. These were the Thunderace dog bones at 165mm crs.
Both were bolted together and 65mm cut out. When they were put in the jig they butted up perfect, then a shallow chamfer was ground each side before welding up.
As usual, preparation takes 20 times the time to actually weld them together.

WRT the heat shield - there is clearance around the frame bracket although it doesn't seem so in the photo. The shield holes are also slotted so there is a bit of give there if required.

I'm not sure if the Staintunes have removeable baffles - it doesn't look obvious that there is something that can be removed. What am I looking for?

[FJools]

Hi Ed

not sure - I'll let you know 

[ribbert]

I've hit mine a few times, with a raised back end, but they are not lean angles you would intentionally go looking for on the road.

At this angle, your mind has already moved on from dealing with the corner to how the accident is going to unfold 


(BTW Jeff, you will notice my bike is dirty in this photo)

This is what the older Staintune mufflers look like, the baffle can't be removed and they are very quiet. The later ones have removeable baffles.

FJools said, "I'm not sure if the Staintunes have removeable baffles - it doesn't look obvious that there is something that can be removed. What am I looking for?"

Usually, you'll see a screw or bolt head on the underside of the muffler tip.  Once this is removed, you can wiggle the baffle or noise restricter out.

[FJools]

Thanks Arnie & Noel.

Mine look like the non removable type then.

Well, the adjustable dog bones turned up unexpectedly just now. I was expecting them tomorrow.

As soon as I unpacked them I knew I was going to have problems. They are quite chunky, designed for a Suzuki Hirebus, and at their shortest setting they are at least 25mm too long. The eyelets are substantial which meant that the relay arm bolts would be too short and I suspect the turnbuckle body, being 17mm hex har, is likely to foul the lower strut bolt.

To get these to length I would have to remove approx. 15mm from each end of the turnbuckle (LH/RH threads) and shorten the rod ends by around 20mm each. Too much hassle and I don't have the time as I'm off to the international Challenge at Phillip Island tomorrow.

So I've bitten the bullet and ordered some 98mm long Lust Racing dog bones.

Disappointed but probably par for the course !
