"all systems go"

just have to find someone to push. the machine is light and compression high. canÂ´t get it going alone.

looks very good...
i have a 3ma and a ypvs and i was thinking to do the same but....

Cant you use the kick start with this frame?

DonÂ´t know if a kick starter would fit. Probably yes, but it was never ment for it to have one

Are you planing on parting 2classic 2stroke to make one?
What I did was finding parts, bit by bit.

Hi Ruka

Great choice
Is it for track? Your pipes are seriously going to toutch the ground in turns. Take a copper hammer and make an imprint of the rear suspension progression system on your pipes. If it doesn't suffer, make a flat on the outside.

hi etienne.
jaaa.. maybe they will touch the ground... but IÂ´ll have to see before I start thinking about what to do.

Anyway.
ItÂ´s ready to role... tomorrow and wesdnesday itÂ´s track time.

I would like to send a huge thanks to all in this forum that have helped me through this endeavour. I feel like the meaning behind forums such as this one really came to the surface. People helping other people overcoming motorbike related dificulties.

WOW! I think we might need video of it running

That might be a bit dificult at the time.
The machine had engine problems.
When a professional builds something that is not std. from the start, then the probability for it to run flowless is quite big.

Amateurs is a bit different... probability for at something goes wrong is quite big, so things should be taken easy at the start.

Part the circunstances, and also me not keeping a better eye on the instruments (wich anyway is hard at 170km/h with 2 race trimed 600s on each side) ment that the engine ended up seizing.

IÂ´ll start rebuild as soon as possible. Hope the damage isnÂ´t very much.

Well, that build is just a beauty!
Video later on when the bike runs? :)

uuuhhhhggggg..... Ruka. man So sucks when they run good this happens. Do let the curious minds know cause many on edge with such a sweet looking bike what went wrong?

ruka · #45 Post by **ruka** » Sat Jun 18, 2011 7:20 pm

Still havenÂ´t touched the bike.
The symptoms after engine failure are kind of hard to interpret for me, so I'm reluctant about making hypothetical diagnoses. Guess I'll just take it as it comes.
The one scenario I'm kind of expecting is a "run-in" type seizure. Ring gap was set to yamaha book spec, and that with only 3X 10minutes heat cycles, and full bananas afterwards... might be tight, especially if jetting was a bit on the lean side... just a non educated guess, might just as well be anything else as there are a couple of things more bothering me a bit.

@aaron: me one myself. I just ment that a pro is likelly to have the baggage and knowledge, to make decisions and judgements that are essencial when building non std. stuff, where there is no manual to tell, this tolerence is this, or this bit more static compression will want this less timing advance etc, etc...

@kenny: hilsen fra koebenhavn

IÂ´m keen on getting to the bottom of this, to prevent it happening again.
