Hi from Johns
Had several of these old girls in the past and had a lot of fun on them.In our day, we used to make a two-into-one out of the original engine pipes and a hotdog car muffler and brought it up the right hand side. The original mufflers did not last long, and the note they gave out with the two-into-one system was fantastic, and we rode them on the road as well with this pipe.
The only problem we had with the SL`s was that the rectifiers in the electricals used to go to lunch, but we replaced them with one off a later model Honda road bike, CB360 i think, and had no more problems.
Cheers
