Got mine a few months ago needs power increase and tuning Fitted Rossier pipe, Pro flow intake and filter kit and MSD Blaster F1 ignition and fuel controller makes a huge difference and no flat spot down low the gears are good on it just gotta give it plenty of guts. The MSD is good tune the timing up and doesnt seem to want to stall as much when u take of at slow idle but with the mods they cant be beat

ok i will tell you as it is . i have one i owened it since dec 2008 (one of the 1st after ryan lancaster got his) this bike has now done 80 hours of racing and thats on the engine hour mtr. it has been a great bike . what has gone wrong with it is

1) i had the batery terminal snap on me . they replaced it and then they didnt clip itonto the plastic clip that is betwen the battery and the circit breaker it was fixed under warranty.
2) there was a recall were the wiring loom was rubing on the frame so that was fixed under warranty

all that happened with in the 1st 6 months

i fliped it on a sand track and bent the steering stem . so i thought that was a bit crud to bend in the sand but at the same time i broke my PEP steering dampner on the same crash , so maybe it was harder then i thought

i went through 4 gytr rear mufflers and they all fell apart . but now they have brought out a 2010 drd pipe (gytr and drd are the same company) and i have given that one hell and its held up good for over 20 hours now. the 2010 drd mufflers have a black tip and the 2009 have a grey tip, i have bent the std rear axel as well

i had the engine pulled down at 50 hours and the piston/rings were in great condition the didnt need replacing but i had it done while the bike was pulled apart .

over chrissy this year i striped the bike down and had the striped and repowdercoated and engine done and new bearing all over due to the muddy hard pack tracks i race on (mud and bearings dont mix) but on saying that they didnt need to be changed i just did it fo i dont want to have my bike poo it self half way through the season.
the engine has had a stock piston put back in it and stage 3 hot cams,gytr/dyno jet 3 computer , gytr header pipe , drd muffler and gytr high flow filter and when i took it to the dyno it pushed out a nice 50 hp at the wheels .i now have lager +1 A arms on it with elka elite long travel shocks and a dura blue axel . and for some reason i have been through 3 seat covers ?? i keep tearing them with my boots when i ride (that could be my boots or the way i ride )

this year i have done 30 hours of racing (on the hour mtr) and it is back in the bike shop getting new valves put in it ( just to be safe) but i have had only one issue with the bike and that was i spray CRC all over my bike after a race day and on one of my races what just happened to be a state round the crc had got into the little hole in the side of the engine were if you get water inthe spark plug area that is were it will come out from , well the crc went it there and it had a stray spark and pooped the spark plug cap up and off the plug (bike stoped)

and the latest issue is coz the muffler is solid mounted to the frame the side of the sub frame were the muffler mounts is now cracked . (alloy part of frame)

this is the truth it is my bike that i ride not what i have heard from some one else so good or bad as it is i hope this helps. as far as i am concerend i have given this bike hell and it has held up well considering .

I hope this helps Smile
