Whitehouse K17 mods...

Reminder – this is modifying a 2018 CB1100EX.

First, a quick recap...
I’d removed the old exhaust system. I’d put the ‘bike on a jack because of space constraints in my little workshop. I’d loosely fitted the outside (numbers 1 and 4 cylinders) pipes and silencers, and 2 & 3 pipes, but my jack prevented fitting the inner silencers. These will have to wait until I’ve fitted the new headlamp 'ears'/indicators, the new m/guard and I refit the front wheel. I can then lower the 'bike and fit Numbers 2 and 3 silencers, before finally fitting the tank and side panels.

So off we go...
Fitting the new Wyvern exhaust pipes is straightforward. They're numbered 1 to 4, cylinder 1 being the left side when sat on the 'bike. Slide on the finned alloy clamps (included in the kit) and offer up each pipe, putting an exhaust gasket (NOT included in the kit!) in the port first. Loosely fit the header clamp nuts to the cylinder bolts, to allow adjustment throughout the system while assembling.





Measure the distance from tyre sidewall to footrest hanger and insert appropriate spacer washers according to the instructions – my ‘bike didn’t need this.



Assemble the silencer/rear footrest bracket and install on the rear footrest hanger.






Fit the protective chrome covers...



...and slip the silencers 1 and 4 onto the exhaust pipes 1 and 4, loosely bolting up to the frame brackets. Tighten them all later, when the entire system has been fitted and has been properly adjusted.



Note - I'm now leaving the rest of the exhaust until I lower the 'bike. If you're working off a bench or on the ground, you could carry on.
