750 set up @ Steve Jordan's

[muffles]

Took the 750 down to Sarah & co's on Saturday to get the ECU remapped. Bike is standard apart from a full (US) Yoshi R-77 system in stainless steel (Sarah mentioned the Ti system actually gave more power).

Headline figures: 128hp up to 130hp at the wheel (both with the full exhaust on, as I fitted it prior to the remap, so no chance to see standard power I'm afraid).

The full throttle line seemed like it wasn't too bad initially, although it was running lean lower down the revs, but got some real gains on part throttle (got graphs for 25%, 50%, and 75% for your perusal).

I had a look around on Gixerjunkies for figures other people had got for 750s on Dynapro dynos (I know, I know, the absolute figures don't really mean anything, it's the gains that show you more - but I couldn't help checking!). I saw a couple around 132hp at the wheel but with a full exhaust + filter - I'm not sure how much effect the filter will have. Outside of Dynapro dynos, I saw some quite wildly varying figures - from 123hp at the wheel for a standard K8, to 138hp at the wheel for a full exhaust/filter/PC3 K4 or 5.

I think the figure I've got is pretty much expected given the dyno, and the mods, so all's good :thumright:

What difference did I feel? I only had the ride home to really try it out, as most of the riding I've done since was town riding & not really suited to testing out the difference ;)
But in the short bits of open road before I hit London again, I can say it did feel a bit livelier. I wasn't going full throttle so I am guessing this is some of the impact of the part throttle remapping. Looking forward to trying it out properly, here are some graphs!

What year bike have you got again?

[ThEGr33k]

Nice. The numbers dont mean a great deal when you compare them mate, so dont ;) The 138 run might not be because it is a better engine, a little playing with the dyno could be the reason for this!!!

Nice curves there though mate ;)

2008 - was only really comparing the graphs to K4 on, as the engines I thought were supposed to be broadly similar...

Yeah I know what you mean, I just did it out of curiosity - on the same dyno (Dynapro) I only saw up to around 132hp, and I think Sarah actually commented on GJs how the other brand (Dyna-something?) tended to read 5-6hp higher. 130hp at the wheel is plenty for me lol!

[fatneck]

130, thats a serious amount of power!

[muffles]

:D A bit too much for my commute, I think I realised today (normally I commute on a CBR600F). Basically you have to pootle everywhere, any significant twisting of the right grip sees silly speeds on the speedo, I'm too in fear of losing my licence!! CBR is much different and allows you a bit of revs before you're going crazy.

[fatneck]

Is there any part of you that would rather be on the CBR when you're out blasting on a Sunday? Just so you can give the throttle a good twist as opposed to keeping the bike in check so much?

Or am I talking silly...?! :-)

Talkin' silly ;)

I commute through London so basically it's all 30 zones & traffic lights & junctions...that's really why you have to pootle everywhere...out on the open road, it's lovely! :D

[fatneck]

...is the correct answer!

So do you ever think about swapping the CBR for something a bit more suited to London commuting - a DRZ400 or something naughty like that?? So many questions!

Wouldn't mind one *as well*, but I wanted to keep a decent faired bike around for a couple of reasons - first, when travelling outside of town in crappy weather (I'm a tart and like to keep the 750 clean given I have 2 bikes!) and second, I want a bike to eventually take on track and not worry too much if I break it. I really need to get out on track, lol.

So you interested in changing to a 750 then? :D They are on 0% finance at the mo... ;)

[fatneck]

Makes perfect sense. Deffo keep the CBR then, it will be perfect to take on the track. I've only done one track day but it was awesome, and hope to do some more this year.

I've actually got my eye on the 08 ZX-6R rather than the GSXR (just for the cost really) and I think I'd be tempted to keep my current ZX for the same reasons as your CBR. 750 on 0% as well tho, hmmn........ :-)

To be fair, the ZX-6R is a real bargain at the prices I've seen it at! Does it have 0%?

[fatneck]

Its 0% over three years and I've seen them for about 5 1/2 grand. Grrr !!!

Are they? :) Sounds tempting! Best price?

Lol - I dunno what price you can get them for, but there are 0% deals available: http://www.suzuki-gb.co.uk/promo/000210/

Just need to find a dealer that wants to shift a few ;)

I've got a K6 with standard everything except PCIII. 132 max hp at rear (originally was 128) but the big increases were 40% throttle, 10hp gain from standard. Bet the Yoshi sounds nice!

132hp standard with PC3 is good! What dyno was that on? I had read in a magazine that a full exhaust doesn't actually give that much over standard (think it was Superbike) as they had one with a full exhaust, wrote it off and then got a standard one mapped and it only made 2hp less, or something. I guess that the K6 exhaust is a little more free flowing than the K8 too lol, big ol' chunky thing...

I got similar gains on part throttle so good to hear it's not uncommon.

The Yoshi sounds great! It gives it a throatier sound - my K7 600 and K8 both suffered the same 'problem' where it sounds nice as standard but when you rev it, it's very high pitched and no 'growl'. I still had that problem when I changed the end can on the K8 - it was only when I got the full system it changed that sound. I think it's the cat, because a mate of mine's K7 600 with an Akra stubby sounds much more 'growly' (is that a word?).

[SV650Racer]

Hiya.

Sorry Muffles i havent had chance yet to print off a stock K8 dyno chart to compare.

Its the dynojets that read about 4-8bhp higher than a dynapro dyno.

The bike we had in after yours made 138 but that had a full yoshi system and is by far the best we have seen from one.

I will try and get time in the next few days to get a stock 750 chart up and overlay yours.:p

No probs :) what Yoshi system did that one have, out of interest?

[Balky001]

not sure what dyno is ran on, same as my GSXR600k2 which made 104 with some bits done so around what I was expecting, doubt it was out more than any other given all the vatrables dyno test seems to come with (humidity/temp etc). I've not seen many standard 750 with less than 130hp with a PCIII or similar.

Was thinking about getting a system but guess it would mean re-mapping again so more £'sss. Keeping stock for now. I did put on a GIPRO http://www.bikehps.com/acatalog/GIpro.html which not only looks very nice in blue but gives a much smoother throttle action from closed and of course more access to low down power.

From stuff I've read I've been getting the impression that remapping on standard parts is actually quite worthwhile, i.e. you'll still get some good gains, so I could definitely see it being the case that 130 is at the lower end of the scale for a remapped 750. Mine is probably due to how I ran the bike in, lol.

Does the GIPRO mean you now have 2 gear indicators? :lol:

Sarah - I was thinking afterwards about filters...do you know if they make much difference? I know a lot of people will add full system & filter, so I wondered if it would do anything (I don't think I'll do it, at least not for a long while).

[SV650Racer]

R55 system.:cool:

Watching this thread with interest, once I've got used to mine I may have a look into this mapping or PC3 lark.

PS anyone upgraded their 750's supendy bits, this I can see as being aplace to extract more fun :)

Not me, I'm not good enough yet lol!

Although, I recently read that the main reason to change suspension was if your weight meant that the range of the standard suspension needed altering - since it is fully adjustable as standard if you can adjust within the range available, there's no reason to change...

I only read that somewhere so may be wrong!

[Balky001]

haha, yes and no, I bought it for the TRE but I stuck the blue gear indicator over the stock one

[ThEGr33k]

Going to get mine dyno's again tomorrow... See what a difference the Eprom has made to the terrible fueling and power. ha ha. Need to ask them to do a run with and without the baffles as im not sure which one is the better feeling. If I had to guess the bike feels better with baffles, as its always wanting to lift the front lol. :rolleyes:

Ill let you know... if you care. :p

After playing with mine (I know different bike) I know that what muffles says is right. You shouldn't have to change the suspension on a gixxer really, only set it up and at worst if you weigh a lot more or less than what the bikes set up for (spring rate) then you might want to change the springs.

To set up suspension start out with sag, set the preload front and back so you get between 1/4-1/3 of travel as sag about 35mm average. If you need to know how to do this then ask. From there set the compression and rebound damping to stock and ride it. If it feels wrong then think about how it might be, asin which dampening might be making it feel wrong. e.g. Over a bump leant over, the bike tries to pick its self back up, thats too much compression dampening on the front...

If you need any more info then ask me ill happily help... I learnt a HELL of a lot getting mine setup just right!

Oh and one piece of insight that will help. You wont get your bike feeling great leant over and going in a streight line, youve got to figure out which you'd prefer... (im not saying that one or the other will feel absolutly terrible, just that the bike will feel better at one or the other depending on set-up).

Cheers. :)

[muffles]

Oooh more dyno readings, gimme gimme yes I'm interested lol. What did yours make before?

As you should be able to see, 113.5 and 69ftlb of torques :) But as you can see the fueling is a bit fubar :(

I might do me a mod of the airbox today as well... ha ha. Right got to get my brother up as it involves wood :p

Ill get all my data put on my memory stick and play with it. :)

That torque curve looks nice!! Kinda shows the difference between an IL 4 and a twin, less HP but more torque, in a handy little picture :)

I'm not sure how to interpret you having to go get your brother up, because it involves wood :o :smt043

oops... He is a joiner :smt026 ha ha ha

Aye plenty of torque. If I can make it reach 120 with some simple mods ill be happy... :) Without being able to make an engine rev though I cant do too much more :(

Paper Mache... Hmmm. Don't get me thinking :p

There you goes. Not too shabby at all I guess. Nice gains all along :)

Oh and for reference:
Blue line = Blueflame exhausts with standard eprom and baffles in
Red line = Blueflame exhausts with Gabro eprom and baffles in
Green line = Blueflame exhausts with Gabro eprom and baffles out

Will hopefully be doing a mod to the air box so ill see how that feels on the ar$e dyno then maybe go and see what the real thing thinks. :D

Nice 8) feel much different?

[ThEGr33k]

Nice 8) feel much different?

It did when I put the eprom in, which was a while back now... I haven't got a PCIII. Eprom is a new ECU basically, got a bit of ignition advance in the bottom to mid which explains the big increase in power there and more fuel all over as you can tell from the bottom bit and the increase in power...

I went to have it Dyno'd to see if there is enough fuel going in to take a bigger air box, and I think there should be, the dyno guy said he was impressed with the fueling so happy days :D

So next mission is to increase the airbox size and see what happens, if the ar$e dyno is happy its an improvement then ill see what the real dyno thinks ha ha.

Only £25 for the runs too. Yippee. :smt026
