Title: St1 cams K1 to K5
Post by: MAWO on Sunday, 03 June 2018, 04:03 AM
Hi All, I recently aquired a nicely priced set of new St1s. But after receiving them in I see it says K1 to K5 on the box. This could be a problem as I have the last year model.
  My Question is: can i fit these to my 2007 bike??

Cheers

Max

Maybe you should head over to the bar and introduce yourself you'll find everyone much more friendly
Yoshi st1 cams fit all years but you'll need to remap using a power commander and with a akroprovic full system will look at around 135bhp.

As Seth says they will fit all years including the 2007 K7 model that you have - but you will need to remap with a Power Commander and to get full benefit fit an Akra or Yoshi Cyclone

Hi MAWO.

Cams are a great addition to a 14.

What spec is yours currently at?  As others have said, the bike really needs a full system like a Akro or Cyclone, PAIR blanks, a PC3/5 and some dyno time to benefit fully from cams IMO.

There is also a thread on fitting the cams here if you look as you need to modify 1 of the can clamps and re-shim the valves.

Thanks for the info. Glad I didnt waste my dosh!
Got a full Akro system so gonna start looking for a PC. I had the bike on the dyno a 10k back and it was 132hp. As far as I know it has not been messed with. I fitted the exhaust and a K&N but thats it. Had it since 2009 and it had 14k then. Now it just over 60k (kms)

because PC3 is discontinued, Dynojet issue PCV fo GSX1400 (20-056)
https://www.ebay.com/itm/Dynojet-Power-Commander-PC5-PCV-PC-5-V-Suzuki-GSX1400-GSX-1400-2002-2007/401501344468?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649

You also may use PCV for 1250 bandit (20-010), if you get it cheaper, but if I didn't have one, I would go for 20-056.

132 bhp with just an akra system isn't a result I would expect.

As a reference... Mine has just an akra it has 120 ish bhp.

Maybe your engine has been worked on...like a Hoegee tune.

I'm not sure how they are measuring the bhp on that dyno but I've never seen a gsx1400 without updated cams get more than 120bhp
Normally the pipe and a power commander remap you get around 116bhp
You'll notice a big jump in power and how the big goes after fitting the cams.
Good luck with it all.

I'm with @seth with measuring differences.
To be honest, I do not understand when people talk about dyno runs, what kind of bhp they talk - on rear wheel or "corrected" by transmission losses engine power. Also dynojet software have 6 or 7 different build in corrections which corrects values depending of air pressure and temperature and e.t.c. The only more or less reliable numbers are numbers comparing to you own runs before and after some changes were made :)

My bike has dyno'd at 135/136bhp on the same dyno but got 140.2bhp on a dyno at a show in denmark .
On the same dyno in Denmark my friends 1250 bandit got 106 and they get 98 on any other dyno
The only way to compare nip readings is to run the bikes on the same dyno at the same time.

It's more about getting the fueling right than big bhp numbers.

Theres a Suzuki race specialist not too far away. Hoegee Suzuki. I was planning on chatting with them before I fit the cams. So maybe I will get it on the dyno before. And then take it back to set it up once the cams are fitted. That should give me an idea of where I am.
What do you think as far as PCs are concerned, new or take a chance on a second hand jobbie?
Title: Re: St1 cams K1 to K5
Post by: seth on Monday, 04 June 2018, 07:43 AM
I'd go for a new on if can spare the cash .
Pc111 are around on eBay and the likes sometimes even here but not often.
I think the pcv is set every 250rpm where the pc111 is every 500rpm
Choice is yours I've ran a pc111 for many years with no problem except for it losing its map once but will be moving to a 1250 bandit pcv when it goes back on the road this time.

Close.

PCIII USB is every 250rpm, the older PCIII serial are every 500rpm. Be aware though you can't get the maps & software for the serial ones off the Power Commander website anymore.

I've got a copy of the software if you find out that old though.

A dyno is just a tool what helps you to adjust your engine. In most cases the dyno guy is also the tuner.
Only reliable way to use different dynos is to compare your dyno readings before and after some mod in the same dyno.
My first (and last) dyno run 3 years and 28 000 km  ago was 187 rwhp. Is it correct or not, I don't know and I don't care.
Much has changed after that, and bike runs better and better.. My "arse dyno" can prove it. :grin:

Im on the hunt for a power commander and Think i might have found one but............its from a busa. will this fit, or are they model specific? oh yeah, its a PCV (new)

cheers :grin:

Post by: seth on Tuesday, 12 June 2018, 01:14 AM
I don't think so but others might know more
My pcv is from a 1250 bandit and was on a gsx1400 before I got it .

Electronics of PCV is the same, but connectors are different.

PCV from 1250 bandit suits, because fuel injectors connectors are the same. This model uses connection type, where PVC is connected inline with each fuel injector. PC3 and PCV made for gsx1400 have one big connector, which put PC inline between all fuel injectors and ECU.

Other difference is firmware, where different bikes have different max RPM in setup table. For 1250 bandit it's 12k, and for 1400 its 9-10k (may be wrong with actual numbers).
Also, because of different id's, fuel map from 1400 will not be accepted directly on 1250 PCV. There is a workaround and in general it's not a problem.

Busa connectors may be different, and I do not know what are busas max rpm.

PCV for 1400 are quite rare in europe. Here is one on ebay.

Second hand a PC-3 is always going to be easier to find than a PC-5 as originally and for several years the 3 was the only one available, now only the 5 is available new from Powercommander.

http://www.powercommander.com/powercommander/products.aspx?mk=21&mdl=182&yr=880

I'm very happy with my dyno-mapped PC-3, I don't doubt that a 5 may be a bit better but it's not a real drama with a heavy low tech bike isn't exactly a GP lap holder !

:cheers:

Is there anything different between the one for the 1400 and the 1250? Wondering if there has been any modification to the wiring of the pcv?

Am about to buy a pcv from a guy that is for a 1250 just want to make sure before I do.

I've just looked on the Dynojet site & the part number is the same for our bikes and those blandits, so it should be identical.
