I have a 2004 rev3 250cc, how much engine oil should I add or is there a certain level on the inspection window o should be aiming for? Also the other day I could hear a sparking/ arking sound, after looking I could see sparks coming from the top of the coil where there is a connector. Any ideas what is wrong and what I need to do to sort it?
Betas with a trigger coil ignition are notorious for failures in the trigger circuit. The symptoms are similar to what you describe. Runs sometimes. Then won’t start. Then after a while starts but runs crappy. They usually show spark but never enough to get a timing light on it so it could be sparking anywhere in the cycle.
It’s become the standard recommendation to just send the stator off to a rewinding house to have it checked and usually they will tell you it’s broken. The good news is a rewound stator is cheaper than new and in all cases I have dealt with has fixed the problem permanently. The new bikes don’t use a trigger coil.
So Beta peeps, any recommendation for rewinders? Does West Country still do Beta stators? Looks like trialsport also does rewinding and they have a video of their test jig. Shed engineering at its finest.
Update,
After drying the plug and heating it up over the cooker, she started faultless.. so now the conundrum is do i carry on and see if it stops again and then get the stator done, or do I do that now and not risk it...
Was out last weekend and the bike was faultless till the last hour when she decided to just stop..
Got it hope and it started but with a clicking sound and kept cutting out, then she wouldn't start and had no spark. Took it apart and whoever fitted the kill switch was bodged in.. sorted all the wires and did some soldering and the spark is back, rebuilt and she started first time for 6 seconds and now won't start again.. I have a spark also..
Bought a Beta rev 3 a few months back and it had terrible clutch drag, would take at least 10mins of warming up before it was rideable. Now after doing this mod I can start the bike up and the clutch works straight away with no drag...
Took the bike to the local shop to have the rear brake bleed, on picking it up they mentioned that it was a right pain to bleed and believed that the bar that goes in the master cylinder was to short.. Went out on the bike on Saturday and the rear brake was hit and miss, some times it worked then nothing, you could feel through the pedal like something was slipping...
So before I buy one on ebay as they don't tell you the size of the bar, does anyone have one to measure on theirs?
Lots of tips on here with brake and clutch bleeding...
why are you bleeding them?.. has anything been changed on the systems?
I stripped the bike down to give it a full clean, so now rebuilt but the lines have no fluid in.. I'm more at a loss as why the reverse bleeding isn't pumping in the fluid..
I am getting no where trying to bleed the clutch and rear brake, tried both with normal pumping of the levers but not getting any air or fluid to move. Also tried the reverse method on both and no matter how hard i push on the syringe I am getting no fluid in, I can feel the resistance and when I let off the pressure I get some old fluid pull out into the syringe.. Any tips before I have to resort to paying for it to be done.. I only did my zx6r last month and that was a dry system with no issues..
Evening all, bought my bike at the back end of 2019, being a novice I did a practice day at nant ucha and loved it.. Done one competition which was challenging to say the least, then the local club had to cancel the other dates due to the weather and then we had covid.. so with loads of free time on my hands I decided to give it a good strip down and clean..
Also if anyone is good at identifying bikes, I can't remember the year of this ?
