Excellent instructions and value once again. This kit is for all throttle positions, and response. Very easy installation, too. And indicating if you prefer a replacement or to receive your money back.
I installed your jet kit per instructions and my surging problem is gone. Each kit is custom engineered by 6 sigma to your bike and its modifications.
OK, I lied when add less restrictive pipe.
Not to be confused with a basic rebuild kit. S dear 6 sigma, after installing your jet kit my 2007 yz250f is a different motorcycle. This is not just some jets in a box, where you get to guess at what need, and pull your carburetor 10 times trying figure it out, comprehensive custom engineered 6 sigma jet kit, addressing all throttle positions, response. You only need to order 1 kit for your bike.
Runs perfect. If you notice any exhaust popping, pinging, or pipe discoloration, are extremely lean. We went from 10 minute minimum warm up and still riding w choke, to 3 minutes go like hell.
To you and the entire 6 sigma team families.
Q: I just bought an intake exhaust, why do need this. A:why spend 300 to 700 for exhaust and air filter that produce a 10 increase in flow while ignoring the big loss of horsepower due not installing comparatively inexpensive jet kit increases fuel match. This is a tuner kit, to get everything out of your bike, that it can give.
Q: can I install this kit. A: yes, you it, don't be intimidated if you've never done before, only very basic skills are needed, and it has instructions with full support. The best part - it purred like a kitten while cruising down highway, and idled same at lights. Allow at least 1/2 hour per carb. Q: what size jets come in this kit.
It feels like a whole new bike. Its really helped out with the entire rev range and idles alto cooler than before.
Please feel free to use this testimonial in any way that you fit. Before the kit was fitted, bike would not rev past 5000 and idle lumpy unpredictable but now it idles smoothly pulls like train right up to limit.
Not peak performance. Increased performance designed to improve all rpm ranges of and a quicker throttle response, helps remove the bog.
A: yes, 1 the bike.
Roared to life and growled like a angry beast - awesome. Replacing just the jets does not address throttle, or throttle response, only full. Combined with the new air filtration system, jerkier and jet kit, it must have 20 more hp than stock.
Get maximum performance longer engine life exhaust popping. Feels sluggish. These are signs of a lean engine, jet kit will fix those issues. Before the kit it stopped pulling at 5500 rpm, after starts 6000 all way to red line but Hans't lost any torque lower PMS. The best part was when light changed from red to green.
Jeff hi guys, just wanted to say thanks. Edward this is an 83 gs750 with pods and open header at sea level.
Then 2 for my old xt250's. Completely eliminated the bog issue I was having.
A: time varies, but is directly related the of carbs on your bike. Q: what stage is this kit. A: each kit different, based on the bike, modifications, and operating altitude, so varies. Installation the kit comes with complete instructions for.
Top notch kit. Screams when the throttle is rolled past 1/2 way point.
Unbelievable improvement in acceleration. Dave hi, just wanted to say thanks. Shannon,Lr great instructions kit it runs so good I think its time for a clutch Yamaha SF r6 mike and 83 xt250s another my xt550. What a difference.
The bike is a full on wheelie machine. 6 sigma jet kits provide the parts and installation instructions to enrich modify all circuits in carb, fix this problem, add performance you can actually feel seat. The jet kit worked like a dream and flat spot that has always been problem with my Dayton 1200 gone.
I now have the means and knowledge to be able re-jet in future IE. Have a very merry Christmas.
Q: does this kit come with everything I need. Kit includes main jets pilot jet needle adjusters nylon spacers drill bits for idle mixture modification exhaust modification tuning tech bike specs carb schematic carb synchronize tool how to build for 5 step by instructions with photos ease of installation.
Thanks a gazillion for the huge improvement.
Feel it still needs more on the top end, low mid range after installing.
Benefits more horse power designed to gain a safe in hp with intake exhaust, 3-4 on bone stock. M hey I just thought i'd let you know that after installing your kit my super tenure is a completely new bike.
