Scored a Honda mb5 today.

You stole it I've been trying to get my grubby little hands on one of those for years. That's a killer score for sure B-)

Yep - great find, even if not a scooter
Those are pretty rare and your's is in exc shape. I'm with you - keep that one stock.

They're fun, I've owned a few through out the years. Change that rear sprocket down 2 teeth and you'll hit 65 no problem. Also reeds and an upjet do wonders for take off, with or with out up gearing. They're a lot of fun but don't over estimate them when merging.

Giant Kudos g9...I settled for NS50 after finding only boned MB5's...of course, I'm pleased how that turned out...
I've recently joined this group (LINK below) and you should too ! !...several members are here as well, and also own NS50.

awesome bike. at first I got excited thinkning you might be doing some crazy engine swap. But keeping it stock is just as nice with a scoot/bike like that.

[motormike]

Awesome. Now to source some rings/piston.

Sourcing rings for MB5 is one of the current topics on the facebook page that I linked for you in previous post...

Ive spent a lot of time on one, I currently have its dirt brother mt50

[LMH]

Nice pineapple, you have a lot of cool moped/scooters/shifty 50s. I just recently sold my mt50 with the 6 speed cr80 transmission mod, it was a fun little bike but still not too practical except for fun. Have you done anything to yours yet?
The pipes on the mts are so much better than the mb but they wont fit due to clearances of wiring etc. If you want to move a lot of stuff itll work but I only mocked mine up and never did it.
I always loved my MBs, unfortunately theyre getting harder to find parts for. You can still find some stuff but not like it was.

I just spied a turbo 3 series in one of your pics, I had a '84 745i turbo/ M106 Executive over in Australia in the late 80s that I swapped a Holset turbo and bigger M88 injectors and hit 18 PSI. It was a quick auto 4 door with reclining front and rear heated buffalo skin seats. Ah the memories.

[LMH]

Very nice! 7:1 is great for compression, bad for low end but killer torque soon as you boost.

[paulpauly7]

10:1 is high for a turbo application 7:1 to 8:1 is great if running above 12psi .My na 4age rwd trueno is at 11.5:1 and only runs on race fuel

[LMH]

You'd be surprised what compression a lot of turbo and super charged factory cars are at now a days. But 7-8:1 is most desirable for high torque and hp numbers. For everyday use and keeping an engine at max volumetric efficiency a higher cr is what they use in mass production. Helps with emissions and Also a lot of the time it's a bolt on like he's using on a stock block( i assume) and the turbo is large enough to be efficient with out using a lot of its grunt/heat. Gt series are nice due to the ball bearings and ease of spool. They're really good for low cr engines also. I use to run hks gt35s on my 96 300zx tt.

Treatland sells a ton of mb5 stuff

Depends what you consider a ton. There use to be a lot of pipe and reed choices, not so much any more.

[patthesoundguy]

I consider more than one or two to be tons
