The official Beta Workshop Manual does not have a wiring diagram. I've done some looking but not successful so far. Can anyone provide one or a link? THANKS!

Thanks folks, I did take off the flywheel and cleaned up in there and checked all the wires before I made the first post above. It did finally start but the spark is still weak and it sometimes takes several kicks??? I would still like the answers to my 2 questions: Disconnect the 12-way black connector between the generator and CDI and with the use of a multimeter, verify that the resi- stances read between the terminals shown below fall within the prescribed range: black-white (pick-up): 320 ohm ± 15% red-blue (condenser): 300 ohm ±15 % yellow-brown (services): 0.45 ohm ±20 % I got the prescribed values for the "black-white" and the "red-blue" terminals but there is NO YELLOW terminal so nothing to test for the "yellow-brown (services)??? There is a yellow wire near by but it does not go thru the 12-way connector?? (and it does not give the 0.45 ohm value when tested with the brown wire that is in the 12-way connector Question #1 - Does anyone know what the disconnect is regarding the yellow wire??? Question #2 - I also have been unable to find a Wiring Diagram that is applicable for this bike. Can anyone point me to one. THANK YOU for any help!

My bike would not start (after previously starting easily and running fine) and I've spent many hours trying to figure out why. It had a spark but it was weak! Section 3.10.1 "Testing the Ignition Stator" in the official Beta Workshop Manual says: The stator winding must be inspected while the temperature of the component is ap- proximately 20 °C. The inspection may also be performed with the generator coupled to the engine. Disconnect the 12-way black connector between the generator and CDI and with the use of a multimeter, verify that the resi- stances read between the terminals shown below fall within the prescribed range: black-white (pick-up): 320 ohm ± 15% red-blue (condenser): 300 ohm ±15 % yellow-brown (services): 0.45 ohm ±20 % I got the prescribed values for the "black-white" and the "red-blue" terminals but there is NO YELLOW terminal so nothing to test for the "yellow-brown (services)??? There is a yellow wire near by but it does not go thru the 12-way connector?? (and it does not give the 0.45 ohm value when tested with the brown wire that is in the 12-way connector Does anyone know what the disconnect is???

Thanks for all the help fellows. I THINK I got it fixed with JB Plastic Weld 2 part putty stick!

Thanks for the responses folks. It is a small (~1/4") hole from impact on the left side above the rear master cylinder. I am actually doing a mod to the brake system to install a LHRB to go with my EFM Auto-Clutch so I have now decided to heat and flex bend the air box to allow a brake hose to go to the 2nd (LHRB) part of the Master Cylinder. I have tired to bond to plastic gas tanks in the past for mods and fixes and it is NOT easy an nearly nothing sticks to the "plastic". Any ideas appreciated! THANKS!

I have a hole in the right side of my airbox that needs to be fixed/sealed to prevent unfiltered air from getting into the intake. Can anyone tell me what the air box is made of and/or what would be a good product/material to adhere to it for a long term fix. THANKS!

WOW!!! THANK YOU!!! You have solved my problem. Much Appreciated!

The fuel hose on my Long Range Tank is leaking right where it exits the shut-off valve. I can't see any way to get in there to release it so I can replace the hose. Does anyone have any ideas on how to get to it or how to take the fuel valve out? THANKS FOR ANY HELP!

Thanks for all the good info folks. I've decided to try the Michelin X11 and think/hope I can squeeze it in. I have one on my Beta 200 and it is good! So I have a 2:15 X18 rim and spokes are ordered The bike I'm trying to fit it to now is a Luna Sur-Ron eMC. I love it as it is so light and I have made quite a few mods - 21" front wheel with knobby and 3:50 19" Mitas ~trials on wider rim on back, foot pegs lower and farther back and handle bar higher and farther forward. The light weight "eStart" and smallish size are great for the 77 year OLD guy for the gnarly trail riding I likw and I'll probably try it at a Trials event.

I have a sort of home made trials bike that has limited rear tire clearance. So my question is which of the nice sticky 18 trials tires is the narrowest in overall section width? THANKS for any help.

Can someone tell me how to search for info on a rear tires that would fit my Beta 80 big wheel? THANK YOU!

Thanks - But it appears they are no longer available when you click the link.

I've broken the aftermarket more flexible rear mudguard that I've had on the bike since almost new. I can no longer find this more flexible aftermarket rear mudguard on the internet. Does anyone have a source or part number, etc. - Preferably in the USA. THANKS

I appreciate your communication!

Can anyone tell me the diameter of the pistons in the AJP brake and clutch lever assemblies? Also can anyone tell me IF there is supposed to be a thin "washer" under the circlip that holds the pistons in the assembly. Last time I had mine apart I THINK I remember that the circlip ID was large enough to let the piston come out (therefore a thin washer was needed)- but I may not have had the correct circlip??? ANY help much appreciated.
