What is your opinion on this?

LIke most people on this forum I am very satisfied with my geezee but would like a little more oomph. I was wondering what do you guys think of this ? Suzuki GZ 250 GZ250 Marauder 6 Sigma Custom Carburetor Carb Stage 1-7 Jet Kit
http://www.amazon.com/dp/B006QZG20A/...I34EMUDAA7EAYL
Do you think it might make a difference, knowing that my gz top speed is around 70 mph, wind in the back, in a decline

Someone else recently posted about Sigma 6...

I do not have any personal experience with this product, but I will bet a month's paycheck that is simply a "universal" jet kit that they have slapped the GZ name on. This is acceptable because it has Mikuni jets and parts in it.

It's probably going to have everything that you need - but it will also have about 25 things that you don't. 80% of what's in that box is going to be useless to you. This is why I have always recommended just going down to your local Suzuki dealer and getting a few Jets and doing it yourself.

1) The Needle Shim mod doesn't require anything but moving a circlip (or in some rare cases adding a washer)

2) Upgrading your main jet is as simple as turning a screw driver...

3) Adjusting the pilot mixture is also just as simple.

You can spend $14 on a handful of jets, and then apply come know-how. Or you can spend $60-$80 on a jet kit and then still have to apply that same know-how.

The only benefit to buying a jet kit like this is that you have a lot of different options for when/if you want to play around and really refine your jet settings, as they offer more variety.

Ok thanks.
I was asking about it because I saw the other threads about the needle shim mod etc and it's chinese to me and I was hoping for an "easy" solution...
is there any threads you could point me to, about option 2 and 3, please?

I love my sigma6 kit! Ended up using -i think- a 10 over Pilot jet and a 140 main,it deff runs rich In the heat and preformance wavers on the highway from 65-75 mph at wot. But I have a lot of Waight on the frame and extensive modifacation to exhaust electrical frame and about everything else...it's a good deal! And comes with wonderful detailed instructions.

The kit contained three jets in a range and several shims and a new jet needle but the trick is you have to tell them what has been done to the bike ie open exhaust or aribox mod or forced induction etc,any details help. I declined to drill my carb for a second fuel passage as it seemed silly but it's a option.

**jonathan180iq** · 08-12-2014, 04:01 PM

How much was your kit, if you don't mind me asking?

No one has ever needed to modify their carb so much as to require a replacement needle, and there have been some real modders through here over the years.

Unless you've bored it out, a straight piped header and fully open intake have only ever needed a 140-145 main jet and some tweaking of the pilot screw...

mainlinecoffee · 08-13-2014, 12:18 AM

I think my kit was 68 bucks total,I have pod filter and kinda complicated stack-drag pipe with a rain flapper on it

golem · 08-13-2014, 10:15 AM

You can now find it on Amazon for around 40 dollars.

**jonathan180iq** · 08-13-2014, 10:21 AM

It's not a terrible deal, then, at $40. It's probably only really worth $25 in parts - but having them all on hand could increase the peace of mind value I guess...

Bottom line, then, is that it will work for you if you just want to order something and not think too much about it.

Ok cool. Do you think I will see some change or nothing too noticeable in the end?
