hey guys, I bought the Rossier fullsysytem exhaust, and just now got time to take it to the local shop to have my dynojets put in,,Well, they gave me a call yesterday, and said, they ran into another problem,they said the realized my z had a serious knock in the engine,,they said it could be my valves, or my wrist pin,,,so, i told them to go and tear it down, and fix it y i still had the money!!..Wat do u guys thank it oculd be,, Valves, like wat there sayin, im hopin it want cost me to much, but if anyone has any idea wat else could cause it to be Knockin....Let me Know, thanks..

 

I hope they aren't just telling u that so they can make some money. Did u notice any knock yourself?

 

Rossier Pipes are K!cKA$$..made 15 miles from me in Plover, Wisconsin [img]i/expressions/face-icon-small-smile.gif[/img]

 

well, i didnt really notice a bad knock, when i was at idle i could tell somtin was knockin, but im not for sure if all z's do that...but when im goin i cant hear it...but, they said almost everythang in my engine was worn out,so its costin me 700 Hundered...This Sucks!..

 

Mine is a brand new 06 maybe 8 hrs on it now, I noticed mine has a slight knock at idle, but not at higher rpm's. Not sure if this normal or not. Anyone else know?

 

my kfx400 and z250 knock slightly at idle. I ride the crap out ofboth and no problems.

 

I'm surprised a Dyno guy brought this to your attention... Not to discount the knocking but some valve slap is normal. The Suz Z has a descent cam for a stock quad.. Just pay attention to it and see if anything changes ...

 

ouch. oh well call it maintenance. i just got mine back from getting it worked on, would of done it my self but i have no were to do it. new piston ,hot cams ,cam chain,gasket set ,spark plug,parking brake off,cleaned out the rear master cylinder,ran it on the dyno a bunch of times just under 700.yeah i did not have to have the 12:1 piston ,i did not have to have the hot cams ,but we were in there for to put in new rings ,so why not .
now i find that my fount wheel bearings are shot, and its time to replace the steering stem bushing, ordered the brass one its some thing like $46.00 +38. for the bearings and seals .
sorry, life sucks some times.

if your shop is just going in to replace bearings ,rings and gaskets maybe do so valve work
700. is an ouch

 

yea, well, when i would smeell my pipe..it smelled like gas and oil mix..so they was right wiht that, they r gone put me in some new rings, and the said my tenitioner, had backed out and my cam chain was slapping agaiinst my enigne....so there replacin that, labor will be like 200, plus timing chain, and rings....i reckon he said about 650$..after everythang...this might sound like a stupid question, will it run better when i get it back, i mean, it ran great, to me, before i took it...i mena, power wise seemed fine..but, i dont really know..wat do u guys thank..
