Shift Star Modification? need HELP


Recommended Posts

G'Day all

 

I have done a search on shift star and came up with lots things but no templete or similar on what it should look like after modification. I dont mind if I have to buy one but would much prefer if I could do mod myself so any info on modification would be great

 

Cheers

i do mine on a lathe bit grinder.  it has a nice table on the side.  then i clean it up with a diamond wheel..    i have seen some that the very tips of the edges were taken off PHHHHH  what the hell  yea  that does a lot.    ALSO if you going to do this ONLY and not fix the real problem ( in the transmission)  do the shift shaft also.

the shift shaft" modification is for a different reason..  if your not seeing why  welp..............   but i personally feel just doing one or the other or both is useless without a real transmission modification..  they help kinda  but the real problem is still there.

eeeerrrr  that if the star is "modded" you don't need to do the shift shaft??  was that your point??   if it was  i said  ummmm  naw  the shaft is done for a different reason..

 

i have had bike shift a lot better from just spitting cases also  amazing what cleaning out all that old clutch residue will do for a transmission..  then after a bit  blamo!  no mo shift righty

Would you be willing to explain it to this fella if he politely asked? Pretty please with a blow job on top?

 

I too used to totally think it was the taller nubs on a stock unmodded star that made the extra travel in the shift shaft. But now that I'm thinking about it. The shaft doesn't ride on the star tips, it hooks up on those studs that come out the side of the star. I am currently working with a mull star and shift shaft that's modded and I have been wanting to try it with an unmodded shaft. (Mull star had different geometry)

mull star i believe has longer pins ( to counteract a worn the fuck out shift shaft end) and is machined with the star tips shorter so you don't have to cut them down.  it also has a lil deeper N section ( from what i believe)  i DO actually like the mull bearing conversion for the shift roller.  that seemed to work well

 

i know what i know from years of trial and error,  then spending a year with a trans in and out of a motor trying all kinds of combinations until one actually worked in a real 421 stock cylinder motor making 55ft lbs of tq and 80+ hp.  in my experience  if you want one to work all the time and work well with higher hp and tq AND shift full throttle it takes more than just a star and shiftier modification.  if your still not sure what it is that modifcation does  welp take some time and figure it out...  i'm sorry i wont just go into detail with full on HD pictures and complete examples of the work i do with them.  it took time and money to get them figured out..  its no big secret  just a certain combo that i found to work very well...

Um no that was not my point. Dont get your panties in a bunch. What i was responding to was your post above where YOU said  you felt they were useless without further tranny modding. While Im sure that this said further modding helps quite a bit, to say the shift star mod is useless is , in my experience, false. That was my point...
