Morning Chappo, scouring the forums I picked up that you had repacked Bultaco exhausts by opening them up etc. I think I need to do the same as mine are untouched. Before a plough in with the Dremel, do you have any photos or drawings as guidance? Would I be right in saying it is the front box, and the upright section of the rear as the square end section has just baffles and doesn't contain wadding? Not having welding facility, I was thinking of riveting a plate over the holes?

Thanks for help!

Continuing the Sherpa 198a strip down last night highlighted a couple more things!

Both of the 19mm bolts securing the rear cast engine mount bracket were tight, but there was some play allowing the engine to move slightly i.e. being cast the bracket wasn't a tight interference fit to the engine mounting lugs and probably shouldn't be tightened further without risk of fracturing the bracket. Is this normal?

Exhaust. Both silences are dirty, rusty and oily but fundamentally sound.  Theres no indication (ie. welding) that they've ever been opened up and repacked, so can only assume they are as original and will be pretty gunged up. I've had a look through the past posts and repacking seems to be the advice, but how do you do this? Unfortunately I don't have a welder so can you say rivet a window on the rear side etc.

Cheers thanks for help!
