ticking in new stroker motor

[flotek]

the vitos cranks arent welded and HD like wiseco hotord ones and they just seperate and fall apart really easy after a short time ,the super stock pistons crack and fall apart prematurely ,those degree keys shear really easy basiclly everything from vitos for a banshee is junk IMO

I Havent Even Rode This Thing An Hour Yet But Do The Wrist Pins To The Pistons Go Normaly Befor The Connectin Rod?

[flotek]

a wrist pin is not going to just go bad ,if anything it would be a unseated circlip o n the side of the piston rubbing . i doubt any of that is your problem though , where is it (sound)directly coming from ?and what is the squish clearance ?

[banshee911]

I Just Tore The Jugs And Head Of Of It And Replaced The Wristpin Bearings And I Still Hear The Noise In The Bottom End When I Turn The Fly Wheel Back And Forth I Can Hear A Clicking Noise It Sounds Like Its Coming From The Number 2 Side Hard To Believe The Crank Is Only Good For About An Hour But Like You Saidd I Was Running It 24-1 So I Might Have Cooked It Already???think So??or Should I Just Ride The Pi$$ Out Of It Till She Goes Again Or Sell It I Really Dont Wanna Get Rid Of It But Tired Of Putting New Cranks In It

[ky 2stroker]

which is the number 2 side? and did it still click even when you turned it over with the jugs off the motor? and like at what point in the crank revolution does it click?

i really cant see how mixing your gas 24:1 is going to be harmfull.... how can having more oil make it lean...

Are both cylinders firing? Check and make sure you have spark at both plug wires, and good plugs, exhaust from both pipes. Piston to head clearance. Is it a loud knock, or light knock? Take a screwdriver and put the flathead end on the case, and put your ear on the end of the handle (with the motor running) and see if the knocking sound is magnified like 10x in your ear, this will help you locate the area of the knocking. If its not coming from the case, just keep trying this until you locate the sound being really loud in your ear. (Dont put it on moving parts!)

Good luck.

More than likely it has nothing to do with the wristpin or piston slap or anything of that nature. Rod bolts are tightened to spec and Rods installed the correct direction? Piston installed in the correct direction? Bearings in the right spot with correct tolerances and clearances?

because when you have more oil you end up with less fuel. 50-1 fuel rich and oil lean. 20-1 oil rich and fuel lean. if you go from 50-1 to 20 -1 you will need to fatten your jetting to compensate for the lack of fuel and vise-versa for going the other way...


as for the ticking sound, i take it you didnt check your lower rod bearings when you had the cylinders off? you said you can hear it when you rock the flywheel, i would take the intakes back off and rock the flywheel while looking through the intake to see if theres any play in one of your rods. if everything seems to be tight i'd pull the clutch cover and look at everything realy close. i'm assuming by the 2nd cylinder you mean the right side sitting on the bike?
