1st, fix that sig... you're riding a 4 stroke
2nd, yeah, fix the seat lol. I did regular vinyl on my seat too, I just went over the old cover in case I screwed up, I used carpet type contact cement and then stretched and stapled it with a power stapler that plugs into 120v.
I really am trying to stay to the nothing good to say don't say it at all theme lol. tires is about all that stands out to me and red fly bars it looks like I guess the grips too lol. exhaust I can see, but to me "restore" means back to stock. build/rebuild is usually aftermarket. that could possibly just be an opinion tho... no offense man, it is a nice ride. just for me, I did a mini chopper (my 1st rebuild ever early this year)
from this
to this, in a month, outta pocket was only like $50 to redo it... the pitbike I put more money into as I got better parts for it, but I gotta find pix of it, if I even still have them. but basically I blacked it out too and just cleaned it up. I fixed brakes on both and cleaned carbs (neither were running) then just rode um a little and sold them for mini quads which I still have one that I'm hoping to sell and get my son a better mini quad
that was my 1st seat, the 450 was my second and came out better, you don't see the staples...
I'm not trying to ride u, just trying to show you how I did my 1st rebuild.. motor I painted too but didn't keep my pix up after I sold the bike those are 2 of the few I have left. got it in feb, sold it blacked out in april iirc maybe march
not to thread jack, just trying to give u something to think about for your rebuild. not that there's anything wrong with yours, just giving you some ideas
