bansheerabbit Posted November 5, 2013 Report Share Posted November 5, 2013 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 Rabbit Quote Link to comment Share on other sites More sharing options...

camatv Posted November 7, 2013 Report Share Posted November 7, 2013 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. Quote Link to comment Share on other sites More sharing options...
possum Posted November 7, 2013 Report Share Posted November 7, 2013 Camatv, when you do the star mod it looks like the shaft mod is useless. Since there is less throw to go up and over the star peak since its shorter. This is just what I have found. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted November 11, 2013 Report Share Posted November 11, 2013 Have to agree. That is why the stiff OE spring is better on the shift pro. Especially on modded stars Quote Link to comment Share on other sites More sharing options...
camatv Posted November 14, 2013 Report Share Posted November 14, 2013 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.

Tech AS Posted November 15, 2013 Report Share Posted November 15, 2013 I did just the shift star mod when i split my cases and i noticed a HUGE difference from just that so... Quote Link to comment Share on other sites More sharing options...
camatv Posted November 15, 2013 Report Share Posted November 15, 2013 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 Quote Link to comment Share on other sites More sharing options...
rubberneck Posted November 15, 2013 Report Share Posted November 15, 2013 completely agree with cam on this one, the shift star mod and the shaft mod really have nothing to do with each other. You need to look at how the system works and why the shaft mod is important. Quote Link to comment Share on other sites More sharing options...

rubberneck Posted November 15, 2013 Report Share Posted November 15, 2013 you can wow all you want, i know exactly what he is refering to with his comments and the fact that you are arguing the point makes me realize you arent grasping the concept here. take a look at it, it will make sense, im not going to explain it. 1 Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted November 15, 2013 Report Share Posted November 15, 2013 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) Quote Link to comment Share on other sites More sharing options...
camatv Posted November 15, 2013 Report Share Posted November 15, 2013 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...

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...
