  1. There is no O ring fitted to the standard air-screw although some after market ones do have them. We have never fitted an aftermarket air-screw and have had no problems. Always remove when cleaning the carb as the pilot air drillings can block up. Before removal check setting by carefully screwing in until it bottoms - counting the turns before removal, don't lose the spring! Air-screw setting is normally 1.5 to 2.5 turns out from fully in, and a long bladed screwdriver will reach it under the silencer for fine adjustment. Regarding the tickover screw, once freed and greased the plastic one is ok, but an aftermarket one is better and you need the spring from the original and that gives sufficient tension.
  2. Whatever length will not affect the carburetion and the up through the frame routing is the neatest solution and best protection. Make the run similar to the 2nd picture, push the tube up inside the frame until it stops, estimate how much to cut off the end and cut at an angle so that even if it comes up against a flat face, it cannot be blocked. Next time you remove the carb for cleaning, it comes out with the carb, and you just slide it back up the frame when refitting.
  3. Regarding the connection at the right hand side of the carb, the horizontal one goes downwards and the vertical one is the vent which on your bike is led up inside the side panel. An easily available petrol cap vent can be fitted on the end to prevent the direct ingress of water. On later models, the vent pipe was run up the hollow frame section, so that the end is up above the highest opening so well protect from direct water. I would route it that way. If your tube is rock hard, Splat Shop has Keihin bits including the overflow and vent pipes. See attached pictures. Carb vent tube routing.pdf

    Will it fit a 2020.

    Beta do a plain plastic one fitted to all later years models which will fit all earlier models (mine was 2011) and are available from Beta UK or through dealers. It is held between the rear edge bash plate and the bottom of the frame and may need a locating hole drilling in the bash plate. And it's a good opportunity to remove the bash plate and straighten out any dents so it is a stress free pull up into position on the engine!
  5. Contact the Beta Importer John Lampkin Imports at Skipton, they will have the parts.
  6. Splat Shop do all the Keihin aftermarket bits.
  7. As far as I know the Factory bike had red anodised bits all over the bike and a titanium front exhaust from standard, so it doesn't look like one. For any 2nd hand Betas you can check if the year and model is as advertised by going to the Beta uk website, parts finder and type in your frame number and it will tell you the year and type.

    2010 evo tuning

    The 2010 was a great bike and quite zippy, as later they changed to softer 300 engine. If it has a flywheel weight it can be seen to be secured to the flywheel on the right hand side of the engine by two Philips type countersunk screws - that does soften the engine a bit. Those screws may be loctited in so warm the heads before trying to remove and make sure that you have a perfect fitting bit -you don't want to chew the heads up! Check the colour of the throttle tube under the twist-grip rubber, if it is black it is slow acting, if white - fast acting - so you want white if you want more instant response. Pilot jet is 48, 125 main, JJH needle, with clip usually in 2nd slot from bottom -2nd richest. Depending on conditions, air-screw around 1.5 turns out from fully in. Obviously you have to make sure that the passages in the carb are clear as if it has not been cleaned the small passages from the air-screw for the pilot air block up. With a bike of that age, if it is well used, the reed valve petals on the inlet between carb and engine may be getting week, Boysen ones are good. Has a previous owner changed the sprockets as gearing up slows response, I have a note saying that it was 11 on front and 41 on rear. If it ever did road trials or SSDT people gear them up (put a larger front sprocket on) for a higher road speed - then use a lower gear than normal in sections. Hope this helps -let us all know!

    Age of beta 300

    Your bike with the unpainted frame is either 2009 or 2010 and they were 290 cc up until 2011 when they changed to 300cc capacity with a black frame. I put your frame number into the Beta UK website Parts finder, and it comes up with EVO 290 2T MY10 -so it is a 2010 model with a 290cc engine which was a great bike.
  10. It's true that this capacity bike is not always advertised, but certainly John Lampkin imports a limited number into the UK (many of which are pre-ordered) which are usually sold very quickly as it is a ace bike. Regarding the handbook, you get a Cd in the box of bits supplied with the bike and the spec is specifically for the 200. The 125 has a different stroke to the 200, 250 & 300 which are the same stroke, and Carb settings and sprockets are the same as the bigger bikes. Enjoy yourself as it is a very capable bike with smooth usable power and easy to ride!
  11. Remember that sometimes the pipe curves higher than the master cylinder and that is where the air gets trapped. Preferably you need a rising line towards the master cylinder with no high spots so the air wants to return back, then just keep pumping and releasing and trapped air will work it's way back to the master cylinder..
  12. As misscrabstick says, the pipe on the bottom of the float bowl is just an overflow pipe to run any leakage down the back of the engine. However, when you fit one, make note as in your picture that you cut a little "v" cut in the pipe 50mm or so from the clip -that is to prevent syphoning . Splatshop do the genuine Keihin vent/overflow pipes which don't harden like some plastic tubes.
  13. If they have the original wheels, both of those bike should have the latest EVO tubeless wheel with spokes laced into an central flange on the rim. The spacers for these wheels are identical and the disc should run about central in the caliper. I have seen that the standard snail cams differed slightly in contour over the years, and as you have two bikes of different years, you could have one of one type and one of another type fitted to the same spindle -worth checking as a few mm on one side could make all the difference. If the alignment is out it will also cause the chain to try to come off the spockets and snag. The other point is that the stop for the snail cams on earlier models was an aluminium lug part of the swinging arm which can get damaged and affect alignment, whereas later models had a socket head screw screwed into the swinging arm for the snail cam to notch onto. If you are checking the alignment with string or a straight edge, remember to allow for half the difference in width of the front and rear tyres! Hope this helps
  14. That is the valve which goes in the top of the damping rod on the damping leg of the forks. The small adjusting screw in the top cap limits the lift of this valve so throttling the oil flow and so the damping. If fell out when you took the cap off the damping rod! If missing, there will be minimal damping and it will be very bouncy. It goes in dome side down.
  15. Hi Peter, Clearly as you have blown some coolant out, check that the engine is full of coolant see attached. Beta EVO Cooling System Check.pdf
