Yoshi cams installed

Hi, finaly the yoshimura camshafts are installed  

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.

Nice results.  
How about a bit of an introduction of yourself to the forum.  Tell us about you and your bike.

Not too shabby! Still got really good torque too!

How did you raise the compression?

Might be a dumb question: is it a 1200 or a 1250?

It's the 1250.
I raised the compression by shaving the head

Today i had my first street ride. Below 3000 rpm it lost a little torque, and after that it seems very alive. At 6000 it realy wake up and until the limiter it is very very strong.

X2, there is a whole Topic just for that 

Impressive results, although personally as I'm getting older and lazier I'm not sure I'd want to sacrifice any of the low rev torque

Kudos to you for the work involved in getting these results, some impressive figures and with a bit of fine tuning and fuel map tweeks I dare say more to come

However, I'm with Chook (and he is probably right about it being an age thing), its the lazy low down grunt that keeps me attracted to the 1250, to be in any gear and having a small twist of the throttle to get you out of trouble.  To tell the truth, the only time mine has spent any real time up in the high revs was on the dyno, its nice to know its there, but my sedate riding style means its the lower revs where I spend the marority of my time.

Still, we like hearing what can be done to our machines, so don't let a couple of old farts (sorry Chook  ) deter you from where you want to take it.

These figures show what can be done. They also probably show what Suzuki should/could have done in the first place.

Have you fitted a water temp gauge Bandakias? A bigger combustion bang would stretch the B1250 radiator I'd suspect.

Did you 'dial-in' the cams?  If you did, you slot the cam wheels (sprockets) or buy some variable sprockets?

Regards

No i have not. There is no such indication

Yes, they are dial-in. The stock sprockets were sloted.

Stop making us ask as we hate pulling teeth, just give us all the info




Pretty please with a cherry on top (or is that supposed to be ort grey)

Great results, the gains certainly are impressive  without being critical of your bike, i also enjoy the unmolested Bandits low down torque 

Gee, I need to take the valve cover off mine... maybe while I'm there I can "accidentally" change the cams..."

That's a hefty change....

Hi, sorry for late reply but thinks are a bit grazy here in Greece.
What picture do you want? Off me naked on the beach
On the first post i mention the basic info. I had stage 2 with headers. The modifications are pretty simple except probaply the ecu hacking.
The camshafts were installed and degreed by the mechanic (we did not used the yoshimura timing. For that we sloted the camshaft sprockets ) and the head cylider was shaved about 0,8mm to achive 12/1 compression rate. Finaly we installed the second butterflies in again and removed TFI , as we hacked the ecu of the bike for fuel map and rised the rev limiter.
For info purpose only, the mechanic told me that this machine has a lot more to give. The yoshi cams are very small and bigger can be used more compression and head porting.

I have video with a Gsx750r of a friend of mine which shows the power of bandit.
The strange think  i found out after trying different sprocket compinations 17-45, 17-43, 18-43, is that the fastet compo is the 18-43 .

Some more hidden power!
Gsxr 1000 throttle bodies plus porting. True rev limiter 10500rpm. Is a little off on the dynograph.

Very nice. I hope you've attached the suspension along the way or it'll be a fair handful

Crikey. That is serious power and torque. 

I believe I have a pair of gsxr cams for the 1200 in the shed . Maybe someone wants to try them . I will need them replaced with stock ones Or these sent back but no hurry .

Nice work!!!
I think it's time you make a new youtube video of this awesome machine. 
A walk around and fly by would be cool.
Has the exhaust note change?
Did you use the Holeshots Re flash ECU?
What year model throttle bodies fit?
What's next???? BIG BORE KIT!!!

oh yeah, hi everyone! 

Photo with gsxr bodies. The only thing i want to improve is the throttle cables. Reverse them to fit from up of the bodies.
The intakes adapters are custom made from me   with hayabusa boots. I did fit the throttles with stock boots but it did not work. Very few power gains on top. Just the adapters help quite a bit to optimize the flow.

Next step should be a decent intake camshaft. The yoshimura one is quite small with 8,8mm lift and only 234 duration. Propably one with 9,5 lift and about 250 duration gets me near 170 rwp.

Awesome work mate!
Did you keep the bandit injector or GSXR?
Keep up the good work @Bandakias

Gsxr ones. From bandit did not fit. The bodies are from 2004 model. After that they have 8 injectors so was very hard to fit them.

Any word on the braking and suspension?
