Available 70cc BBK's for NSR50 Part#s

[NCNSR]

ok why cant i just buy a 72 piston and gasket kit and just bore my cyl? the autoboy kit has oem stamping on the jugs they use...

Dont quote me on it but i think those cylinders that they start out with are the high performance 50cc cylinders from honda not the one like on your bike and then they add there special sauce, port the intake and exhaust mill the head and cut it to fit the cylinder precisely and to raise compression........So the answer is sure you can but you probably wont beat them in a race.........These guys and Billy wiese for that matter are getting anywhere form 12 to 19hp at the wheels so they claim.I spoke to Billy Wiese at WRW racing the other day and he claims he is getting 15.5hp at the wheels from 62.9cc....you need more than just going from 50cc to 62.9cc to make power like that.

I just took a look at the molassi link and it shows what seems to me like a kit for an AIR COOLED bike.



NSR is watercooled so is this the right kit I'm looking at?

I was leaning toward that Malossi 70cc cylinder until I stumbled upon this:



Malossi USA - WTH is going on?!? - ApriliaForum sponsored by AF1 Racing, inc.



As far as I can tell, malossiusa.com and malossiusaonline.com are run by the same outfit, Roselle Imports. It doesn't look like malossiusaonline.com has been updated in quite a while, and malossiusa.com shows the "account suspended" page.



Anyone ordered anything from them recently?



Guess I could try ordering stuff from an overseas place, but I've had mixed results from that in the past with some parts for my SR50 scooter.

Mike, I think if you go through Honda50.com, a vendor and mod here, it will be okay. Jason went through him for his exhaust and others use him with success to procure parts from overseas.
