I was having a lot of lockout when I would shift at a high rpm so I decided to see if it was the Kartboy shift linkage bushings. The car shifts A LOT better after putting the stock bushings back on. I didn't think it would make a lot of difference but I was wrong.

 

Mine does this too, I might try that.

 

Buschur bushings FTW

 

I have the zaklee and I love them

 

I thought about going with Buschur's bushings, but I am a little apprehensive about going with metal bushings since they have a tendency of locking up in cold temperatures.

 

If there lubed up enough, you wont have that problem.

 

my friend gave me metal bushings, i think they might be buschur and im experiencing a lot of problems with high rpm lock-out and its real hard to get the car in reverse...

 

Therein lies the rub; you have to constantly lube it.

 

I had the kartboy shifter bushings for over 20K miles and no problems. Just clean them once in awhile and put enough grease on it.

 

I was not aware that you had to grease the polyurethane bushings. That was one of the reasons why I bought them. It makes sense though because they were a pain in the *** to remove because they were stuck in there.

 

I massively lubed my buschurs with Mobile 1 synthetic grease. I have no problem with any rpm lockout.

 

my only lockout is occasionally in forth gear at high rpm but that is 100% because of my ACT clutch...because it happened with the stock bushing too

my car is "more" difficult to get into reverse but it's nothing crazy

question: how often should they be re-greased?

 

i would like to know as well

 

yeah... the plastic itself is fine but the metal it attaches to gets dirty and crap so the grease helps it from getting stuck. White lithium grease and/or anti-seize works very well, also.

 

I have buschur's buschings, never had to lube them and never had them be sticky in the cold. Gets down to -40 here in MN and they still do their job just fine.
