That would be a smart choice cause your gonna need it if you go to a 6 speed or a higher gear.... The nice thing about doing a cam, air cleaner and pipes only is that you're really not going to do much to the reliability of the motor and you'll actually even pickup fuel mileage believe it or not...

It has a mild cam, Super E with the Thunderjet. The heads were flowed and dual plugged and the pipes are Pythons. The bike runs great and there is no issue with performance. It just seems to be turning more RPM's than necessary at highway speeds, certainly more than my newer bikes with 6-speeds. Having that taller gear has to be better for the engine. There is a shop nearby that specializes in FXR's believe it or not. I will consult with them.

The up grade to a Six is worth it... I did it in my 98...

86 is a bag of worms to change over, he'll have to upgrade the primary covers , complete starting system, and the clutch hub and guts to go to a 6. 86 still used the old tapered trans main shaft , starter and clutch assembly.

OP, consider a bit more horsepower motor wise, cam & compression and then go up one tooth on the trans sprocket and you can still keep the same belt.

Swap out the pulleys front and rear. Fifth gear will feel like sixth

Thanks for all the comments. The '86 is a bag of worms. I have had a lot of fun with mine over the years as you can tell. As a teen all I wanted in life was a Super Glide (Shovel). I started with a '76 Sportster in 1979 because that was what I could afford. By the time I was financially able The Evo's had hit the market. The rest is history. I wish I could be buried with it.
