Default 1988 Softail Custom

I install new Billet forward controls. Now it won't shift up it really hard. The old factory control work ok. I adjusted the footlever close to my boot but still won't shift up. The shift rod I don't know that's out of adjustment. I know when I turn it the transmission lever or foot lever won't mover while turning the rod. I need some help. Clutch cable got plenty of tension. All I did was switch forward controls. Transmission got fluid. 5 speed I can get first and neutral.

Not being able to see the two sets of shift controls, it's hard to tell what exactly the problem is...

Based on your statement that everything works well with the old factory controls, but not with the new billet forward controls... The new billet controls would seem to be the issue.

Don't worry about your clutch adjustment, trans fluid, or primary fluid.... They were all fine before, focus on your new controls.

The new controls are binding (cheap controls), need adjustment, and/or the installation was not done properly.

Make sure the geometry is the same as with the OEM controls. You want the angles of the forward vertical shift shaft (that the foot levers attach to) and the rear vertical shift shaft (to the trans) to be at the same angles that they had with the OEM controls. Make sure the joints in the horizontal shift rod are free & loose to move. Make sure the horizontal shift rod between the two shafts is as straight as possible, not at an angle.

A picture might help....

Good luck and keep us posted.

I sent you pictures. Rod looks straight.

It does, but little things can make a big difference in a linkage... I'm not a mechanical engineer. I can't speak with authority about how angles can add/subtract mechanical advantage in a linkage. I can only mention what I have experienced in changing the linkage or linkage parts on several of my personal bikes over the years.

A couple of things I may see in your pics:

On your original shifter linkage, was the horizontal shift rod level front to back? Or was it angled down front to back, with the front vertical shift shaft pushing down on the rear, trans shifter shaft as the new one does in that picture...? That rear vertical trans shift shaft is leaning forward.. maybe not a good idea to push down on it at that angle. Perhaps the push should be more straight on or horizontal? Maybe make adjustments to the horizontal shift rod (lengthen it) to decrease it's height which will decrease that downward push angle?

Make sure the horizontal shift rod is also as straight as possible between the two mounting points, from a side to side perspective. I can't tell in your photo, but would it give a straighter push if it was mounted on the inside of that front vertical shifter arm...?

Lastly, the front heim joint looks twisted in one picture. Is that due to a bad angle on that horizontal shift rod (see above), or is that front heim joint supper loose with a lot of play...

If super loose; Is the bolt holding the heim joint the proper size? Does that heim joint need a washer between the heim joint and the bolt head? Could it be a poor quality heim joint that is just super loose.

In the pics it's hard to see exactly what I look for, but I've mentioned things I've dealt with in the past when changing shift linkages and/or shift linkage parts.

Try this... take a pic (if you have one) of the old shifter linkage. Compare that pic to the the current shifter linkage pic above. See if geometry of that horizontal shifter rod mating to both the front and rear vertical shift shafts is the same....? Since the old linkage works great, and the new linkage does not, I would strive to make pictures of the linkage from the front vertical arm to the rear vertical arm look as similar as possible.

I apologize if I am unclear with my comments. I know what I am trying to say, but I may not be explaining myself correctly.

Play around with that and see if you can get them to more closely match where they push from...
