Has anyone tried the Merge Racing Tech. accelerator pump and ajustable leak jet? I read on thier web site http://www.mergeracing.com/alj/index.php that KTM"s Red Bull Team are all using this product.
I've been looking at those as well, they should work very well. The only problem I can see with them is needing a screw driver, and having to adj it from under the pipe.
R&D racing has a similar product, but it has a thumb screw on the RH side, which works way better. I am going to order one for my 550, I'll post my findings after I've tried it.
