I wanted a new exhaust anyway but - not like this!

— 4 minute read

Last week I got my rearsets sorted, so with a track day booked for May 4th, I thought I would check they worked ok.

You gotta think about these things...

Popped up the road, stopped, checked nuts and bolts and carried on a little. Things seemed great. Then my enthusiasm got ahead of my sensible brain and I decided to pop down the bypass just to "air the bike out a little after the winter". I would live to regret this as my sensible brain would have reminded me the exhaust was no longer braced on the pillion pegs. My enthusiam brain said "twist that throttle - yay!" and soon everything went very - very loud. :(

A drive of shame

I drove home trying not to draw attention to myself, but even a little 500cc bike sounds silly with no end can at all... I drove back up to the bypass both to check no one was injured by a flying exhaust and also to see if I could retrieve it, and maybe just maybe it was fixable.

In a short answer no it wasn't, the end of the pipe had been really bashed and the movement before it had worked loose had flared the pipe aswell. I did my best to beat it out and di manage to refit it but after a test ride I could see a crack in the main exhaust pipe too and it became more and more evident that I would probably need to replace it.

Life takes funny turns and a call arrived (obviously) to tell me there was a cancellation on a track day on my birthday. Well it would be rude not too... it is written in the stars. Time to sort this exhaust sharpish!

Delkevic make a full exhaust system for the CB500, as tempting as the stubby cans were I had a future MOT in mind so went for the carbon road legal one. Order placed Sunday evening and by Tuesday DPD had dropped off an exciting parcel.

I had worried about having to replce the exhaust - back at the beginning of the project I had replaced the copper gaskets on the headers and it turned out the header bolts were a little worse for wear. It wasn't an option to just put a new end can on though as the exhaust had been modified specifically for the Motard.

I removed the header bolts with a certain amount of fear, replaced the gaskets and tentatively tightened things up.

I was not going to make the same mistake twice, especially with a brand new exhaust, so next task was making a brace and finding somewhere on the bike to fit it.

Some research of the CB500 track bikes showed they often use the shock mount, so I got out some sheet steel and fairly quickly made a brace that would do the job.

With everything checked and tightened, I decided not to do anything else to the bike unitl after the track day. Time to start prepping for that.

The track day approaches, and as you would expect the settled calm dry weather is replaced with gales and torrential rain. Would it even go ahead?
