Sigma Stage 3 Carb Tuning Kit

[Gaz66]

Hi Peeps 


I know from experience what the Ivans (Full Monty Kit) does for the might 1000


Curious if anyone has any experience of the Sigma Carb kits from the USA as advertised on ebay, ad claims to sort all the fueling issues that the Ivans kit does, may be a clone of the Ivans kits? never dealt with the Sigma brand before, price works out quite a bit cheaper than the Ivans Kits that are available from (SG Motorsport) .
The only issue is the import tax may kill the deal as it's not stated in the ebay ad, not bought much from the USA before, somehow managed to swerve the import duty on both occasions.

Thanks.  Checked both links, neither shows the kit coming with different needles.  That suggests this kit uses the stock needles and that's not going to be a patch on any of Ivan's Fazer 1000 kits.

That surprised me also Mike, would like to know what Jet sizes they used and if 2 and 3 are different sizes to 1 and 4 if they maintain the standard needles.
