Bully Primary Cover

LIMITED STOCK! Get your BAKER Bully Primary Cover before they're gone for good!

When the stock 6-speed on the 2007 Touring models came out it was clear that the new primary design was one thing…visually weak. We solved this issue by moving in with pure attitude using our Function-Formed™ design as our guide. The motor sprocket cover, inspection cover, and derby cover make this the perfect canvas for your customizing ideas. Give a personal touch - with your knuckles.

The Bully Primary Cover will add the style and cool factor to your 2007-2016 Touring model that the stock primary cover could not. With the introduction of the stock 6 speed on the 2007 Touring models also came a completely new primary assembly. This new primary design got smoother and thus more boring than the previous version.  Being the biggest single piece of architecture on the left side of the motorcycle, it is just begging to be upgraded and replaced.  Having cut our teeth on many designs using our Function Formed cues, we set out to make the primary cover assembly wrap the essential function components of the primary.  We added a motor sprocket cover, inspection cover and what we call the bellhousing around the clutch to break up the large mushy surface area of the stock unit. Adding separate covers also opens up the possibilities when it comes to customizing the aesthetics to meet your demands.

Primary Cover Finish Options
The Bully Primary Cover comes in a hog black with highlights finish.

One of the big differences in the function of the Bully Primary cover when compared to the stock unit, is the inclusion of an inspection cover. The inspection cover can be quickly and easily removed to check chain tension, which is a significant advantage over having to remove the entire outer primary. We included an inspection cover because we also offer a convention manual adjust chain tensioner. The Armored Attitude Chain Adjuster solves the issues associated with the stock auto tensioner. The first moment the chain has enough slack into it to ratchet the shoe up another notch, and thus tightening the chain, it will. One notch tighter might not be an issue, but you don’t have any control of when this mechanism stops tightening the chain. The end result in many cases is the primary chain is so tight that it will start wearing out left side motor case bearings, inner primary bearings, clutch hub bearings and transmission output gear bearings. Our manual chain tensioner allows you to adjust the chain to the proper 5/8-7/8″ (cold) freeplay, and never have to worry about the chain getting too tight. The 28% finer teeth spacing, as compared to the 2001-06 ‘L-Bracket’ style, allows more accurate adjustments. We offer this chain adjuster for fitment with stock outer primary covers, as well as a package deal with the Bully Primary Cover.

Bully Primary Cover Kit Part Numbers 

Bully Derby Cover Kit

The Bully Primary Cover kit comes with the derby cover you see pictured on this page. A good looking part that will set off any style that you rock. We decided early on when developing this primary cover to make sure that the stock bolt pattern and diameter of the Derby Cover was maintained. So that you people could put their own special derby cover on our primary cover, or such that someone could buy just our Bully Derby Cover Kit and bolt it on their stock outer primary. 

Recommended Fluid / Level Picking the right primary fluid ensures the life and durability of your primary, that’s why BAKER recommends a 85W primary oil.  BAKER does not recommend the use of Syn3 (20W-50). For Bert’s article on ‘Oil & Spiders’ Click Here
