First topic message reminder :

Hi, finaly the yoshimura camshafts are installed Very Happy 

Today we did dyno adjustment on fuel. The results are great!

Some info. I had stage 2 with Holeshot headers. Now i added the yoshi cams plus raised the compresion ratio to 12. Also raised the limiter to 10100 rpm.

See below a dyno before and after instalation.

I have Hyperpro spring set front and rear and on brakes Brembo RCS master with sv1000 calipers.It has enough power to block front wheel at any speed.

I know what you're thinking @2wa all go and no whoaaaaaaaaa. Still looks like it would be plenty fun. You might lose some of that road ridability with the power and torque curves moving

Smile The question has now been answered. It would be a monster on the drag strip with 40kg removed. Maybe that's the next step. I still wouldn't like to be chucking it about the Vic or NSW twisties. Still a lot of momentum there but each to their own.

Personally I'd take a quick bike over a fast bike any day (I have both) but that's the environmental and enforcement conditions I ride with (within mostly)

I did some work to the throttle cables. I modified the bodies to fit the bandits throttle cables. I thnk it came out good and finally it is working like normal bandit

Yoshi cams installed - Page 2 WP_20170222_10_36_19_Pro_2

Also i did some expiriments with exhaust. I modified the last section of headers, from 50mm diameter to 54 to match akrapovic, and finally 60mm with another muffler. The strange thing is that while i was hoping for high revs gains there is more gains at low mids. Especially at 2800 and 5000 there is big difference, and at 6300 to 8000 also.

3 fotos, first before, second with 54 and third with 60mm.

I have much difficulty to keep from power wheelie with second gear. Probably i need to change from 17-44 sprockets to 17-43 to keep front down

Interesting. Yes the limiter comes on too early. 170hp? Epic. 

I too am looking at dropping the TFI and going for a flash to lift the limiter and turn other things off. Then get it sorted on the dyno with a PC. 

Are you looking at grinding cams or getting new ones?

I have now set the limiter at 10700, but i have installed stiffer valve springs. The inlet camshaft is yoshimura and the outlet is oem inlet grinded, as yoshi is quite small. I was thinking to grind oem cam if possible to achive about 9,5mm lift or send it to a company for hardwelding it. This way i can save the yoshimura set and sell them.
Last time engine head was off the bike, we raised the valve seals clearance as it limits the camshaft lift at 8,8mm that is yoshi. Also valve springs can't accept bigger cam. With the new spring installed 9,5mm lift is possible.

Now about raising the rev limiter with stock camshaft is not very helpful as the power drops a lot at high revs. Probably about 500rpm more is enough.

Ive hit the limiter a few times mid turn so another 500rpm would be useful. Not for more power. 

Let me know when you want to sell the Yoshi cams.  Twisted Evil

That certainly looks like you know a thing or two about welding up an exhaust pipe.  Yoshi cams installed - Page 2 959052286

So you think the bore of the whole thing is to small?

On another note, what are your thoughts of pod air filters? While back I read a comment from Dale Walker that he tried them but always lost 2hp up top. But he didnt use velocity stacks. I do wonder if these could really help as well. 

My one goes on the dyno on Tuesday for its flash.

I think that header tubes diameter are small. I will try with bigger and see what happens. About pods i have nothing to say, try and tell me too what to do Very Happy Very Happy Very Happy

With your Gixxer bodys, nothing I will do will work for you. 

Very interested in what you say about the outlet of the headers giving a mid boost.

Yes, this is why i am going for bigger headers. As i understand it, gaining with bigger last section of the exhaust at low and  mid ( between those there is a area that it lost 4300 to 5500) and loose at top end, it is because of loosing some gas velocity. So probably the headers have reached at the point which can not deliver more.

Hello folks, i never posted the final  result of my project, sorry for that.
My bigger header depending what you are looking was on positive side. If you are for good looking Very Happy and high rpm power it was a success. For overall performance not, (except good looking Razz ) Here the result with back to back same day dyno.

After that it was time for my intake camshaft. It was reprofiled in a quite bigger duration letting the engine breath more on top. If you compare the to dyno charts, the result from new header and camshaft is about 8hp and a about 12hp on rev limiter. It made for sure a big difference on how the bike pull  on high revs.

Yoshi cams installed - Page 2 Empty Front end

Post  rnai034 Sun 03 Mar 2019, 6:23 pm

Mate, that front end looks great.
I'm in the process of swapping Hayabusa forks on mine as well using the same yokes fabricator (as well as using fork extensions to keep the geometry).
By the looks of it you've got an ABS model as well - With that fork swap (+ RCS 19, + new callipers) have you kept the ABS? and does it still work as intended? (or more directly, were you able to get that certified?).
I've been chatting with a certifier here in Sydney and the ABS seems to be the sticking point. Along with the forks, I intend to use an RCS19 master cylinder + Brembo M4 callipers. 
Given those changes, I have been given two options:
1. Prove the Bandit ABS module has been used in some other bike with this (or a comparable) configuration from the factory - coming up with nothing on this right now.
2. Downgrade the system to a non-ABS spec one
