Idled the full tank like a train (Had oil all over my shirt so thats a good sign it's rich enough )

Did the rest of the boring breakin (I hate breaking in engines...) with no flame outs for the rest of the 7ish tanks. Slowly leaning it off.

Had to wait 2 weeks till our next prac session, but I got it purring along with a good - but not 100% tune...

Had plenty of good sparring sessions with my mates OS Speed (My 808 Vs Hyper 9)...
I wouldn't say this engine is faster, but neither of us had a definite advantage anywhere in the Rev range. Ran the same plug since breakin... no problems all day

Running :
Ascendancy 4 Shoe Clutch 1.0 Springs
XRAY 16T Clutch Bell
TTR 2035 Pipe
OD 97T Plug

Ran for 10m 22sec on a full tank with this setup... (Only timed once however)
Not quite enough for me to pit at 10 - which pipe would get me some extra seconds? (Im not brave enough to risk running out of fuel )
Hyper RX7, thanks for posting your experience so far! Regarding the pipes I have not personaly tested the 2035 but if memory serves me right the concesus seems to be that the 2013 provides slightly better run time (and better performance) so if that is indeed the case the 2057 should he a big boost in run time. I would recommend that you give that a shot especialy in buggy as it will also smooth out the bottom end plus probably give you 30+ seconds of run time. Another thing to try especialy if you have enough top end is going with a 6 or 6.5mm reducer and you can also limit your throttel opening tonaround 90%. doing both of these will make a marked improvement in run time! Hope that helps, let me know if you have any questions.
