Slip on's

09SV650S

Well-known member
Read on one post someone talking about mapping air fuel ratio bc of changing their exhaust. Should this be done for a simple slip on or just full systems?

Thx
 
In general, any change in the exhaust system (slip on or full system) will probably require some alteration to the amount of fuel or air being received by the engine.

Slip on won't effect A/F very much.. but that doesn't mean your bike's stock A/F is ideal. If you plan on spending the money to be able to re-map you should absolutely spend the extra couple bucks for dyno tuning.

Thats a good read, so in short, my M4 will make it run a little more lean than the already lean factory settings. Ideally a power commander or proper A/F map would just make it run better and be more efficient?

I've always been told leaner is better (safer) when it comes to mods?
 
^leaner is not better as it promotes detonation. Easiest way to describe this is to use your check engine light as an example. When that light comes on it runs the vehicle in safe mode by enriching the mixture therefore preventing less damage in the short term. However running a vehicle long term rich will effect emissions components and piston ring longevity. Basically the best thing to do is have the vehicle tuned for the appropriate mods.
 
I'm not sure about the dual spark SVs but my single spark pointy was a little rich from the factory.

For the most part SV riders follow:
- Slip ons don't really require a remap, but it would be nice
- With a full system one should remap, especially to leverage the power benefits of a full system
- However, at any point a properly tuned map will help the SV.. in terms of power (with the appropriate mods) but more so in the smoothness and linearity of power delivery

The slip on is pretty much the only engine related mod other than a K&N. Which shops are recommended for this kind of tunning?
 
Pro6 in Etobicoke. I can't think of anything in K-W (haven't lived there in a long time) but I can ask a few buddies from back home if you need recommendations.
 
Im pretty sure Riders Choice has a dyno as does Z1 cycletech not sure if there is something closer to you though?

Ya man that would be great. Dont mind heading to TO area (want it done right) just have to run her lean till I get there in the spring :) good thing is no codes or lights, but heard one small back fire yesterday when under good throttle. city driving runs great!
 
On the SV popping on decel is usually caused by the emissions system (PAIR valve, adds air to the exhaust stream to aid the burning of left overs) not from a lean condition. It's normal but can be avoided by blocking or removing the PAIR system. But that makes Captain Planet cry at night.

Sorry I don't know anybody personally only used my own WB and street tune but i'm still carb'd.

Great info.....I'll probably get it mapped properly in the spring to be sure and keep her mint! But in the mean time I might have to recycle more to offset my carbon foot print :)
 
Cycle Improvements in Waterloo has a dyno and lots of experience. Also make sure to set your tps sensor easy to do and makes a huge difference just make sure to set the right one there are two on the 08+ SV your diagnostic connector is at the back of your fuel tank left hand side on the ABS model.

I do have an 09 ABS model. how do you set this TPS sensor you're talking about and what happens when you do/dont do it?
 
Throttle position sensor is on the left side of your TBs under the tank.

For an 09:
Note:
- No idle adjustment required (skip this step)
- Only 1 security torx screw instead of 2

tp sensor adds fuel to the mixture once past idle.. a well adjusted bike is smoother on the low end and on/off throttle

Thats a great article. Just not sure if I trust my mechanical skills enough to mess with electronics :( changing a tire. installing slip on, fender eliminator ill try it all but. This stuff I worry about screwing it up more. lol

Maybe I'll try to get Cycle Improvements to dyno it and set the TPS all at the same time in the spring? What would these kind of adjustments run for? $$$
