ill tack a pic of the other side,they are machine finished both sides

**Hootguy** · 11-30-2012, 12:20 PM

yup,,so are mine,,,but they seem like a better finish on the positive side,,,and on the Yosh bikes,,i have always seen them used on the plus 3 side,,,they must use them that way because of the clamps they were using at the time,,

**cobramadness** · 11-30-2012, 12:33 PM

Oh ok, I was thinking you had 40 at the same time, haha

**BenjaminDG** · 11-30-2012, 01:16 PM

Those disc rotors remind me of my gsx-r 750w rotors, same pattern and surface (grooves instead of holes).

Do these brake harder then the rotors with holes in them?

I assume becaus of the greater brake surface but dont these also warp easier?

**speedy sie** · 11-30-2012, 02:09 PM

if SERT used them in world endurance id say they last longer then the brembo's of the day??

**dj_smurph** · 11-30-2012, 04:34 PM

I thought the grooves removed glazing from the pads. Drilled discs cool quicker and are prone to cracking around the holes at the constant high temps track bikes are inflicting on the brakes. This is just my thoughts based on car brakes

awsome build man

cant wait to see the finished thing

**HARLEYFERGUSON** · 12-04-2012, 08:14 PM

Love this thread, quite the attention to detail...by any chance would you happen to know the black finish used on the XRF swing arms? I've seen some I swear were anodized, and others that I thought were painted, possibly with some type of thermo bonded polymer? I have a K7 works arm that had to be stripped to clean up a bit of "abuse" and am now in a quandary as to replicating the finish..perhaps I could give you some work if you have some answers. Cheers. Mike

tremclad,,,,but you have to be sure ans shake the can really good,,LOL

**speedy sie** · 12-09-2012, 10:09 AM

no have a front wheel 16.5....so all go,go on the front end now.

**speedy sie** · 12-11-2012, 11:36 AM

front wheel here, fitted a dream mag unit..

also coming soon..

works xr clip ons very trick all titanium bits and billet ali hinged to allow q/c change
work xr bettie gusrd and titanium bolts
tokico works vented rear disk all titanium bits and carrier,so will have full tokico works set up,may have a lead on a tokico m/c
xro tubes hopfully

the works tokico callipers fitted on ,but need new carriers to get them on right,as i have brembo carriers at the moment.

so the bike will be one more step to compleation

**BenjaminDG** · 12-15-2012, 05:21 AM

Simon

What are those 2 tubes coming out of the valve cover?

Extra crankcase breathers?

Isnt the crankcase ventilation located here?

Why is it located there?

On my gsx-r 1100 engine it is located here?

Would it be better to have an extra crankcase breather closer to the crankshaft like on a srad and newer gen engine?

**speedy sie** · 12-15-2012, 07:23 AM

the zx7r had a par rebrether system that comes off the exhaust port,taken off on the race bikes,its there because of emission laws in some countries.

**BenjaminDG** · 12-15-2012, 08:04 AM

Ah those engines were not srad engines?

Would it be better to have an extra breather in a simmelar place like the srad?

Or why did the srad and newer gen engine have their breathers in that place and not ontop of the valve cover like the 1100 engine.

Doenst that remove the gasses more easily?

**ccmhunt** · 12-15-2012, 09:08 AM

It was up on the valve cover on the zx7s ( and most other later models) to route it into the exhaust which allowed the unburned hydrocarbons to complete the burn and reduce emissions.
It is not a crankcase vent, just a pair valve.

**speedy sie** · 12-15-2012, 09:12 AM

a lot goes in to crank case presume..but just lately iv been jumped on on every forum when i post any info,so ill keep it to my self...sorry..
yep the two engines are zx7r engines, that have crank case breather on top of rear casings and 2 top "par" air set up, which is a Chris pointed is there for countries with tight emission laws

**TT750** · 12-15-2012, 09:20 AM

much easier to block off too!!

**speedy sie** · 12-15-2012, 09:31 AM

yep here is my 7rr kit head with it done

**ccmhunt** · 12-15-2012, 10:04 AM

How did you do that? And it's not often I say that to anyone you know.....

**BenjaminDG** · 12-15-2012, 10:50 AM

But would my engine benefit if i made another crankcase breather in a similar position like the srad engine?

Can the breather be a simmple hole with a hose coupling attached to it or do you need something with a labyrint in order to allow the oil not comming out of the coupling?

I would like the blueprint my engine so is it worth the look into the crankcase breathing aswell?
