You do not have to rejet when using Slip-On pipes. I have an 1100 and an 650 for my wife and we have had Slip-On Cobra Pipes for a few years now.
Change your exhaust pipes.
30 mph stock...40 if you change the exhaust and bore it out
Read the user manual of bike and then concern your mechanic.
yes they can produce more power or torque but after you change exhausts you usually have to change jets also
Read the user manual of bike and take the services of your mechanic.
You need to drop the exhaust to reach the oil filter
drop the front exhaust pipe ,remove cover behind pipe ,filter is in there.
Road Star Clinic has an excellent 'how-to', complete with pictures here: http://roadstarclinic.com/content/view/158/116/
Its located on the very front of the motor down by the exhaust pipes.It has a round housing and it takes a 12 mm to get it off..
with the motorcycle on the ground install tire change tool from tool kit across the tabs on the frame then put motorcycle on center stand. Remove rear fender bolts to raise rear fender, remove axle bolt then remove rear tire.
It depends. The fuel injected motorcycle will already have a management system, but you may need to modify its behaviour if the exhaust modifications affect the fueling significantly. There are many devices available on the market to achieve this, the most popular is probably the Power Commander by Dynajet.
lighter oilin my 2005 Yamaha xvs 1100 i use penrite 5w 40 because it helps with the gear change .is a lot smoother because clutch plates don't seem to stick as much.give it a go.
