I replaced my clutch plates for my 02 gsxr 750 but it seems to be slipping still

Clutch pack gone? Drive belt/chain/shaft gone? Since the clutch pack is inside, are you sure it's good? You may need to rebuild it... which, fortunately, you can do without dismounting the engine.

just replace your clutch plates,you can buy themfrom Redline and in respect of your running problems,you need to start with the basics ,I/e plugs first.

u need to adjust the free play in the clutch lever

Your shifter cam bolt has backed out, this is a common problem on earlier GSXR's. Happened twice on my 2000, both times during race weekends.

Stop riding the bike and shifting at all and do the following repair:

Remove clutch cover - you'll drain some oil so make sure you have a drip pan underneath

Remove the 5 the clutch housing plate bolts - careful as they have pretty stiff springs behind them providing torsion

Remove all the clutch plates - make sure you keep the same order and re-install the same way; matter of fact if you have never replaced your clutch plates, do it along with this repair.

Once the clutch case is basically empty, you will see at the lower left a small assembly that looks a bit like a tuning fork, at the end of the shifter shaft. There is also a cam there with rounded cogs. There is a 8mm or 10 mm hex head bolt that holds this cam, and I'm sure it has backed out and is causing the cam and shifter to not engage the gears properly.

Remove the cam bolt. Spray some compressed air or even a light spray of brake cleaner in the threaded area where the bolt you just removed is. Make sure the threads are clean and dry.

Place the cam bolt and assembly back in its position, and take some RED loctite to the shifter cam bolt threads. Make sure to torque the bolt to specifications, I think it's 24 or 28 nm.

Let the bolt set for 24-8 hours, then reassemble the clutch and replace the clutch cover gasket. Top off the oil and go riding.

Are you sure you've placed the plates the right side in? Has your clutch grip, "dead" route before becomes tight when you grab it?

There could be several reasons for this, firstly try changing you oil and filter and see if it improves. If it does then it is possible a problem with the friction plates being glazed or bent slightly. Check to see if the clutch slips. Also check other things like chain tension and sprocket wear. Whilst your there check the cussion drive rubbers for wear and loosness.

Make sure the cable didn't slip out of it's detent. If it isn't placed exactly where it should be, you gon't get proper tension on the clutch plate.

Changing the sprockets & chain shouldn't have changed the clutch. Pull things back apart far enough to make sure you didn't get something in the way of the clutch plate free play.

Contrary to what the speedometer might say (and GSXR 750 owners), a 2008 GSXR does not have the displacement to reach 180mph. A road test conducted in germany had a rider reach 181mph - or what said 181mph on the speedometer - but was actually clocked on radar going 173mph. 173mph is what a GSXR will reach at around 1200 feet altitude and 65 degrees fahrenheit. Depending on the altitude and temperature, you might have slight fluctuations. If you want to go 180mph+, just get a GSX1000R
