i have not done nothing to my bike since i have gotten it I'm wondering where i should start with a tune up, i feel like i don't have a good top speed and i have to change gears faster than normal than again i know my sprockets are bigger than there supposed to be thats why my gauge is off, but where should i start with a tune up? what do i benefit from doing what your suggesting ty for your input

 

bump?

 

How many miles are on the bike?
How long have you had it?
When and what servicing did the PO do?
What mods have been done?

 

i have 17k miles on the bike
had it since last august but has only been ridden about 600 miles on it since it looked like this at the time and did a lot of changing to the looks only
i don't know of any service that the po did
no mods have been done other than fairings

 

I would service everything. All fresh with a maintenance starting point is the way to go.

Change the oil and filter.
Change the coolant.
Change the brake fluid and bleed it through. Good time to upgrade the lines.
Change the fork oil and replace the seals. Good time to put in new springs for your weight.
Clean and check the chain and sprockets. Replace as necessary.
Check the brake pads. Replace as necessary.
Check the tires. Look at the date code on the side to make sure its not old rubber too.
Replace the fuel filter and air filter.
Replace the spark plugs.
Valve adjustment should be done at 24k, but you could check/adjust them now if you want to get it out of the way since you will be most of the way there doing the plugs.

 

Ok well I just did an engine coolant replacement wanna do the oil change next but I don't know what to use somebody said if I use synthetic my clutch could get worse or better? What kind oil should I use brand? Grade? I know how to do the oil change just don't know what kind I should use and should I use a k&n oil filter?

Tks guys

 

Oil brand doesn't matter much. What does, is that it's oil meant for bikes with wet clutches. Look on the back for the JASO-MA certification.
Synthetic is fine if you want to use it.
Use an OEM filter or one of good quality. You can use a K&N if you want to spend twice the money.

 

Any oil that can improve my overall hp? What grade should I be using?

 

Oil won't improve HP.
Any grade of oil produced these days exceed the grades that were around when your bike was new. I think we are up to SN now. If you mean what WEIGHT you should use, the consult your manual to see what's recommended for your climate. You will probably find you fall in the range that most weights overlap.

Personally, I use Rotella T6 synthetic.

 

Does that only come in 5w-40? I was told to use 10w-40
