i belive its 36mm

according to the vin.# the tenth digit is the year so m is for 1991

Any engine will fit, with enough custom modification. However Kawasaki makes 400 and 600cc sizes in their "K" series. Also I believe their is a KX 175 that is almost exactly the same as what you have, only with more displacement. If you are just wanting more power you could think about boring out the pistons and putting in larger valves. Otherwise known as a "big bore kit", this is usually easier than creating custom engine mounts.

Sounds like an internal issue. If the other gears work, you might have to get the engine out and get it split open.

go to bikebandit.com and look under the oem parts. it should be a list on the left side of the page. and find manufacturer. then it is all diagrams from there once you choose the bike. note: all of the parts are numbers and it is a list of what everything is called and priced. it really helped me out and still does. hope this helps.

no mate,with the rack all the way out both booster ports should be wide open,if you replaced the valves check that you didnt end up with two the same cause there different.If you didn'tmark or note left& right you may have them in backwards. Hope this healps

seems like somethjing foreign could have been forgotten in the transfer case. this most likely is causing the rattle, when the viberation from the motor reaches a certain pitch or frequency.. best to have it checked by a pro...

Check the plug. I have had a very similar problem just recentley yesterday infact. It could be that you are running the oil mixture too rich as well...Good luck

You need to get a service manual for your model and read it my friend.

It takes a 1/3rd of a liter but it wil take about half a liter during the instal. Have fun with it!

it is not your plugs it is electrical

Need to get the vin # off the bike to help. should be 17 letter and # long

Good luck and please rate

there is many brand that supply spécialy formulated gear box oil for 2 stroke transmission
i would say that motul transoil is a very good one...but it is like religion and politics....however you have to get a non detergent oil due to friction plate application....

you cant go wrong at 20 to 1, but you can run 40 to 1 as well

If your vin number is correct you have an '02. You need to read back to the eighth digit on the vin

Have fun, I don't know why it can't be as simple as just install the part and put it back together. You will have to swap wires around until you find the right combination.
Hope this helps.

if you contact your local dealer with the frame number they will tell you the build year.

It sound as if the top-end of your motor is getting a bit tired. Being a two-stoke engine you'll have less components to work with then a four-stroke. You'll want to remove the head and cylinder. Take your time with it and keep it clean. Do it right and have the cylinder cleaned up with a new piston and rings. On assembly use a torque wrench, you'll be working with aluminum so it strips easily. I am uncertain if you need to pull the engine but if not I'm sure you'll want to remove the fuel tank, exhaust and carb. Use a digital camera or phone to take photos as you go. Take the time to tag parts as to what goes where (A to A, B to B) Clean all items before assembly.. do it right the first time.
Hope this helps,
