big problems

[HellaMoney]

hey i got some problems about the 5 time this bike **** the bed on me. I went to go start it and it would not start so i pop start it spurred for about a min them warmed up seemed ok but then i wont idle and keeps staling.....but it seems when its warm it will start ok the electric start. but it still seems to run ****y so i figured i cant hurt to clean the air filter when i took the seat off i found that there was about a 1/2 pint of motor oil not filter oil in the air box..so its been siting in my garage for about 2 months and now the warm weather is coming and i wanna ride but i dont know what to fix or whats wrong with it.....so anyone know whats going on there? :ermm:

its blown up and the piston was probaly stick to the cylinder and when you where pop starting it , it was ripping the piston through the cylinder. so all the oil is goin though the overflow into the airbox

[RATPACK Z400]

Could he just have overfilled the oil ?did same with my Z oil went in box drained out oil was fine.

[atveric132]

i doubt it because if it was just to much oil in the bike it would run fine

Piston and rings took a crap on you, time to break it apart and replace them.

mine did the same thing, how old is your bike? suzuki took care of mine all $1700 of it. the piston rings were not set properly from the factory. wore a real smooth ripple in the cylinder:ermm: thank god for warrenty

[HellaMoney]

mines an 06 whats year was yours?... i really hope mine is still in warranty!

[jherbie28]

it was a 06 but it happened about 4-5 months into it. did you just get it as a left over being that its 2009 now? the dealer and suzuki should stand by it if they determine its there fault.

[Robin Hood]

Top end is shot. Had the same thing happen to me in one of my races. Make sure you get the newer 08 style piston.

[HellaMoney]

Well I don't think Suzuki is going to cover it because I bought it the day it hit dealers. I guess I am just going to have to fix it myself. Anybody got any recommendations for a good new piston? I want a higher compression then stock but I don't want to have to run race gas its way to expensive for me.

I personally am a CP piston fan, i believe you can go to about 13:1 without using race gas. Also im pretty sure ATP Racing Engines has a cylinder replacement system where you just send in your jug and money and they send you a new jug.

[Baracudaaa]

I just put in a CP 13:1 with a Hotcam intake cam. Night and day difference over the stocker, the power is gnarly. You can also do it yourself if you are even a slightly decent mechanic, not saying that I am though.

With a 13:1 comp piston I wont need to run race gas?

im pretty sure you need to run race fuel with a 13:1 piston

[atveric132]

you need to run 50/50 93 with race gas. in my practice bike i just run 93 and c12 mix. but in my race bike i run mr9. practice bike is 13.5.1 race bike is 14.75.1.......your also not gana get everything out of the piston with just pump gas
