Exhaust bracket fouls panel

Postby Knowledge » Sun Jun 17, 2018 9:55 pm

After my trip to the excellent Eight Balls rally, I noticed some damage to the right panel in the area at the rear of the kick-start cut-out.

Have finally got a chance to look at the cause, and the panel is hitting the CNC machined rear can bracket manufactured by Scooter Loopy John. I've used this bracket on other scooters, but the panel-work differs somewhat.

I can only think that other people have suffered the same issues. How was it solved, of did the bracket need to be changed for another type?

a friend had the same issue, much more damage than yours.
he swapped for a different type.
you could shorten the spacers and use a longer bobbin if that makes sense.

Can you not turn the whole bracket anti clockwise by one bolt hole and use the spare hole that is showing in your second picture to secure the exhaust to?

Can the bracket be moved down on the case I’m sure that is how I have done mine and seen others?

Cheers Shane.

Try a longer rear shock.

Thanks for the replies guys.

I did consider moving the bracket around the rear of the crank-case by one stud. It is certainly possible, but whilst my panel is currently hitting the middle of the three mounting points, if I rotate the location of the bracket, the panel will be hitting the top mounting point instead, with the same effect.

I have a R1 shock, which is short, but it gives excellent clearance around the reed. If I fit a longer shock, I will lose that clearance, and I still wouldn't be certain that it wouldn't bottom-out on the biggest pot-holes. I also don't want to pre-load the spring, as it will make the ride harsh.

Keep the ideas coming, but I would be surprised if this was an unknown problem with this SLJ product. I am considering an alteration to the bracket, with a bit of help from my tame ali welder, and a grinder.

I need to check whether this might give the necessary clearance. I will check. Thanks SL.
