My DS7 Journey
« on: October 20, 2020, 07:05:46 PM »
Growing up my father spoke very highly of the old Yamaha two-stroke’s. Almost as though they were these legendary machines, now I know they are. I lost my father early in life, still he helped instill in me a passion for the motorcycle. So when this little Yamaha DS7 turned up just around the corner from me, I jumped on it. I paid too much for a bike that is beautiful, but mechanically shit. I just felt a connection with it, so the money doesn’t matter.

It’s my first Yamaha road bike, so I’ll have questions along the way. Hopefully my restomod process will interest some of you. The direction will likely change multiple times, my builds always do.

I’ve had it for about a month, made some changes and much more are coming. These photos document them in order.

Being new to the Yamaha club I spent a lot of time researching. I started looking at pipes because the old set up have some huge dents. I believe them to be JR power pipes. Facebook pointed me to Garret at GRA2strokes. His Millennium GP pipes looked perfect, so I ordered a set. I should have them this weekend. After finding out he doesn’t just make pipes we started talking about setting the bike up with a R5 top end. 

So this is in the works!
R5 top end, Wossner piston’s, stage 2 porting (open up intakes and exhaust cut down sleeves on main transfers weld exhaust gasket and match to pipe flanges, raise and aim transfers. Machine heads with o ring and dowel pins with proper squish and compression ratio for pump gas.

I also pulled the trigger on an alloy TZ350 style tank and tail. So who knows where this will end up.

It did come with the seat, I’m still debating whether or not I like it. It is however very nicely done.

The CB is a long time project, my intention is a CR750 style hot rod.

Well I should’ve taken better pictures when the pipes arrived, but I was excited. So I sent them off to get ceramic coated. Went with a semi flat black color. The quality of the silencers is excellent!

Thanks man! The angle will change, I was waiting until I knew where the pipes would fit. Still need to set everything up the way I like it.

Super cool! I'm also a fan of the TZ look, but IMHO that bike is a rear fender away from being just right  :bacon:
Rubber side down!

Thank you, and I agree, I think this bike is almost done. I’ll just need to build another one, start from a frame.

The rear fender has me sort of stumped at the moment. The frame was previously cut, so fabricating something decent is a challenge.
