my rod bearings went out, so we replaced them, along with pistons, piston rings, pins and all that. bikes all put together and everything seems normal, except when i push the start button, the bike doesnt want to kick over, the relay seems to click. fuel pump sounds strong, everythings connected. what can we do to kick over a bike with fresh pistons????????

 

try rotating the crank manualy to make sure everything moves freely... if everything does check your started

 

Did you free spin the crank several times after assembly before putting on all the component?

 

yo take the starter out, hit the button see if it works, i did one the other day it wouldn't kick over, took it out put it back and its all good

 

+1. make sure that **** works first.. as well, make sure the motor is free. rings shouldn't seize within a day or week or whatever.

you re-hone?

you oil the rings upon intallation?

sure it's the crank not allowing movement? could be cams bound up..

lots of variables.. check the simple **** first as always.. good luck!

 

thanks everyone turns out it was the new rings, they were too big.

 

that'll do it.. lol

general rule is .004" gap for every 1" of bore..

 

hey everyone, im still gettin a kinda crazy knock noise when the engine gets up to about 5 thousand rpms. what else can be damaged when rod bearings go out, i had to ride it a few miles to get home as soon as my bike started making that noise to begin with. rod bearing on only one cylinder were messed up, what else can be making a crazy knock noise from inside the motor????
