I had a 750j with M seat unit. It was done by previous owner so i dont know how much hassle it was but it didnt look out of place and dont recall it being a lash up in anyway.
For a while i always wondered why more of these arnt being modded and used. I thought they were a pretty good bike when new. Now all of a sudden there seems to be a few appearing on here.
Oh and welcome, nice bike.
Bad camo paint job, apes, open pipes solid strut the back end. do burnouts.
or just ride the dam thing.i like em, i like the fact theyre not as popular as the other aircooled motorbarges. That said Im still an ET man meself.
Strip em down mate, i had a gsxr with similar issue and it was corrosion/lack of maintainence on the spindle. All weather skanky bike. Much like your machine.
