Nice Bike I fuckn love these things.
Not wanting to hijack your thread here's a small pic of my mates '76 RD400 at WSID. I ride it whenever I get a chance it has RD350 Micron expansion chambers, revs to 9000 and sounds nasty. I just wish it was my bike.

HORN RIDE! Love the old Yammies, the paint job sets it off :)
I'm building a mild fighter out of an old 2 smoke soon :)

My sister used to ride (and crash) one.

They used to fly!!

Sorry but im looking at the pic and isnt the shocks upside down. If you put TZ700/750 reed blocks in the 400s they go like stink. Bit of metal removal required.

[Funkenfresh]

ok, telling me.. 'TZ700/750 reed blocks in the 400s they go like stink.' is not good.. now i wanna do it..
and my honda is never going to finish... :P

is this what your talking bout??

wicked RD ..mate i have a special place in my heart for air cooled RD s http://www.streetfighters.com.au/forum/upload/8607557160819.jpg
ahhh brings back memories ..i hit a concrete bollard about 10secs after this was taken lol..
btw what has been done to the heads ?cos they dont look stock..

[Funkenfresh]

the fella said he got hold of the head, thats one instead of the standard two...
the clutch is slipping a bit, so i gota get that sorted..
and i dont think it should be bouncing at 7000 rpm.. real read line is bout 9ooo rpm

[alfiestorm]

Water cooled kits are or were available for them takes e'm out to 460 I think and about 70/80 bhp. Fahron I think they were made by.

power band starts at6500 and shes usually out of it by about 7500-8000 stock and the redlines at 9500,(check the gearing ..]they chucked out about 40hp stock [yamaha claimed 44] top speed was claimed 105mph [though mine would only reach a real 100mph indicated 110,till i had it breathed on ]like alfie says u can get w/c kits for em but its just as easy[and bout the same cost] to fit a 350lc engine and big bore kit .you should get 50odd hp out of the 350lc powervalve stock,and like alf says about 70hp with the 420kit
The guru to talk to about these engines is Stan Stephens in the uk, he done a stage 2 road /race tune on mine which included blueprinted engine ..porting ,reprofiled heads ,boyensen reeds k&n filters and a pair of allspeeds,after that it made 50hp on the dyno,and its 0-60mph time dropped from 6.5secs to about 5secs
