You are supposed to jet any bike when you put a high performance pipe on it. you can damage valves and rings even with a slip on. i am using a stage 1 dyno jet kit with a yoshi rs3 oval slip on.

You need to adjust your floats on your carbs to the proper level. anytime you do anything to the air intake sytem, the jets, or the exhuast you need to either ask the manufacturer of the aftermarket part what adjustments need to be made, or you can take it to a mechanic so he can figure it out, or do it yourself. i recommend going to a qualitfied mechanic (preferably a shop that works on professional racers motos or a shop that has its own team. they got all the know how. I am taking my 98 zx9r to evan Steel Performance in Tucson once i get my Hindle full supersport exhuast system. It's a little too late for you, but i highly reccommend hindle, they sound great and add much more power than a yoshi does. anyways, i hope that helps you out brother. ride safe!

Hi, Anonymous power loss after an exhaust change is not uncommon if you don't change anything else like a performance air filter, this performance issue can usually be corrected by tuning up your carbs to meet the new air/fuel flow conditions, for more information about your question and valuable "FREE" downloads that you will need please visit the websites below.

Have a problem with a dr650 went to a full stainless exhaust open up the air box fitted 150 main jet .NOW bike runs rich on idle can turn airscrew home and bike will not stop .Could it be a choke prob


If it is running rich you have the wrong size jet fitted, tuning a DR650 uses jets sizes from about 130 to 180 depending what has been done to the engine & bike

Kawasaki zx9r ninja e1 spluttering at low speed but ok at top end


Hi Shaun, This could be caused by several things, but the most common cause is also probably the most common problem with carbureted bikes in general, and that is one or more clogged idle jets. Any time a bike isn't put away properly for the winter, it runs the risk of stale gas drying up and clogging the idle jets. The good thing is, this is a pretty easy fix, but it entails pulling the carbs, then taking the bowls off and squirting carb cleaner through the jet to dissolve the clog. In a worst case scenario a very fine wire can be run through the jet to clear it. To save yourself some time, let the bike idle then see which cylinder isn't firing by squirting water on each exhaust to find the cold one (or ones).

Hi, A_stranahan if you have changed your fuel delivery system, air filter size or flow rate, mufflers or exhaust system your carburetors need retuning and if your fuel system (gas tank, filters, fuel valve and carburetor) is contaminated with ethanol sludge, varnish, rust, dirt, water etc. or your bike has been sitting for months or years without running these components must be "PROPERLY" cleaned and reassembled "CORRECTLY" before any adjustments can be made. Tuning your carburetor is fairly simple once you understand the basic principals. You engine is a simple airbox sucking air in and blowing it out, it is finely tuned at the factory for maximum performance once you upset that delicate balance by changing air filters, camshafts or exhaust systems your performance may go down the and the engine may run poorly, you need to compensate the air-fuel mixture in the carburetor in order for the engine to run smoothly and at peak performance. If you are running multi carburetors you need to sync them first and make sure your air cleaner element is clean and dry for paper elements or lightly oiled for foam and meshed elements and properly installed. Here is how and where you compensate trouble: "TIP" if your engine "BOGS" your not getting enough fuel.
1. Closed to 1/8 throttle is managed by the air screw and pilot/slow jet.
2. 1/8 to 1/4 throttle is managed by the air-screw, pilot/slow jet, and throttle slide.
3. 1/4 to 1/2 throttle is managed by the throttle slide and jet needle.
4. 1/2 to 3/4 throttle is managed by the jet needle, needle jet, main jet, and air jet.
5. 3/4 to wide open throttle is managed by the main jet and air jet.
6. Wide open throttle is managed by the main jet.
If you are running lean, spark plug electrode color is white, engine runs hot and feels like it is starving for fuel you need to go up on the jet size or move the c-clip down one notch. If you are running rich, spark plug color is black or dark gray, engine runs cool, and bogs down when accelerating you need to go down on jet size or move the c-clip up one notch. When your carburetor is properly tuned for maximum performance your spark plug electrode will be a light tan color like coffee with cream. If you prefer fuel economy over performance you can go down on main jet sizes until a satisfactory level of lower performance is acceptable versus MPH, your spark plug color will be whiter and your engine will run warmer. These tuning adjustments will only make improvements if your intake and exhaust system have no air leaks or sealing issues and the entire electrical system is in proper working order and you have no mechanical issues.

I have 1999 zx9r that back fires and throw flame out the pipe when i rev it up counld this be my packing in muffler gone or what help please!


you either have a severe missfire or its running too rich if it iworse when riding the bike and you do a rapid gear change to a lower gear and it pops and bangs a lot its air being sucked into the exhaust system from a leak in the exhaust joint or gasket failure check for blows around the exhaust clollectors or splits around the bracket that holds the pipe on to the bike frame

Bike seems to be passing a lot of oil through exhaust. How much is normal?


The amount of unspent oil you see dripping from the end of your silencer is lovingly called spooge and it is a sign of a rich fuel condition. The common way to solve this by a jetting procedure. Your manual may be able to explain this, and the different jetting parts that are available, but be careful of errors in your manual. I've spotted at least 2 important ones in my 03 manual! Basically you need to replace/match jets for your particular conditions. Winter riding will be much different than summer for example. And Denver will be much different than somewhere at sea level. Find a jetting procedure for 2 strokes and test different pilot jets, needle jets, and main jets at your track until little to no spooge is seen. Be careful, of course, to also check your spark plug for a cappuccino colored tip to make sure you haven't jetted your carb too "lean". Finally, make sure to run 30:1 fuel mixture consistently through jetting (or 32:1, whatever your oil and bike manufacturer recommend).

1998 Sportster XLH 1200 seems too smoky. Carb, including jets were checked - ok. Not visible smoke, but just gives rider that exhaust smell even after short trips. 14 k miles and recently serviced. Is this...


Is this a recent development? Or has it always left that smell? I had an older Sporty, that I ran too rich for years, it left lots of black soot on the inside of the exhaust tips, and a very pungent exhaust smell on your person. When I went down a couple jet sizes, it got much nicer, and ran a little better as well.
