mellis Posted January 21, 2009 Report Share Posted January 21, 2009 Hi, Just bought myself a Beta Rev 3 '06 model Seems to be some confusion on the above topics, i've had various different answers from different people!! Book state 70:1 mixture and A Champion Plug But some people are telling me to run on 50:1..... Whats everyone think, i'd like to get things right before I start using the bike!! Cheers Mike Quote Link to comment Share on other sites More sharing options...
the addict Posted January 21, 2009 Report Share Posted January 21, 2009 (edited) BPR5ES plug NGK, and run on 70ml of Castrol TTS to five litres of superunleaded, assuming its a 250 or 270, 50:1 is too rich. Change the gear oil before you ride it any distance, ATF Dexronlll is good in Betas and dump it regulary Edited January 21, 2009 by The Addict Quote Link to comment Share on other sites More sharing options...
mellis Posted January 22, 2009 Author Report Share Posted January 22, 2009 Thanks for the reply, Yes it's a 250cc - should have stated that!!opps Mike Quote Link to comment Share on other sites More sharing options...
mad4it Posted January 22, 2009 Report Share Posted January 22, 2009 As the addict said above i have an 06 model and run mine on 80:1 fuel/oil mix they seem to benifit from using super unleaded fuel as opposed to normal fuel, plug type bpr5es or bp5es the only difference is one is a resistor plug hence bp®5es!

fivemeister Posted January 22, 2009 Report Share Posted January 22, 2009 Coupla things Manuel recommends a resistor 7 plug which mine seems fine with. I always thought that there needed to be a resistor to stop interference with the electronics. So why go for a non resistor 5 plug?? Quote Link to comment Share on other sites More sharing options...
the addict Posted January 22, 2009 Report Share Posted January 22, 2009 Mike, few other things, if the carb/air box boot hasnt been swapped around yet..turn it, as standard the boot is a larger bore at the air box end than the venturi end, swapping around makes the carb installation alot easier. Make sure you re-pack the exhaust regular, makes a big difference to the running and noise,easy to do and cheap, dont pack it maga tight though. Rear disc bolts have a habbit of coming loose on Betas, check tham every ride as well as the frame down tubes Fitting Boyesen reeds gives a much better response in the throttle and low end running, can get them from HRC1(username) on Ebay Quote Link to comment Share on other sites More sharing options...
stork955 Posted January 23, 2009 Report Share Posted January 23, 2009 Gday, if the manual says go with a resistor plug - do so - it limits the secondary ignition current which can take the CDI out with the wrong one. Also it will pay to clean the entire exhaust, this should be done on all 2 strokes. You will be amazed at the difference. HTH, Cheers, Stork.

totalshell Posted March 17, 2009 Report Share Posted March 17, 2009 seconded cleaned the front pipe out and replaced the stuffing in the silencer all nice.. but replaced the middle box for new and clean and WOW.. Quote Link to comment Share on other sites More sharing options...
dan williams Posted March 17, 2009 Report Share Posted March 17, 2009 I run Delco #4 platinum plug in my '05 but you have to change the plug cap as the tip isn't threaded. The resistor is there to limit the rise time of the spark for radio interference. There is usually a 5kOhm resistor in the plug cap as well. 100:1 BelRay MC1, VP C-12 fuel. Spectro Golden Gear in the tranny. ATF makes the clutch grabby. Quote Link to comment Share on other sites More sharing options...
