hey guys i have a 2003 wr450 that i have done the upgrade on the to the 04 starter gears. NOW this is my drama When i brought the bike the starter was shagged it didnt work and the gears on the shaft were worn down. Now i brought a new one from "motor city reman" and the bike has only been electric started like 8 times an the starter is &%$#@! again. It just clicks on the starter solenoid so i put a multimeter on the leads and it has continuety on both the earth and the power and then i took the cover off the starter gear and seen if it spins and the shaft has ben worn down again. What would be causing it to do this? ALso the only thing i havent done is put the spacers on either side of the gear and cover for the starter gear but i dont think that would do anything??? Can anyone help me out why or how it is doing this as it is starting to cost me too much to fix and ride???? PLEASE SOMEONE HELP ME I love riding but this bike is driving me crazy.
