I am going to buy my son one of these to help him get his carb set up on his bike once we get his CDI sorted.

What do you experts thing of these as a piece of kit for a budding motorbike mechanic apprentice?

I never heard of them but an interesting bit of kit . can a cdi unit be tested to be sure its not working as it should ? I know crank shaft seal's can go on 2 strokes causing something to happen cant remember what though . but it is a thing also don't the exausts need a wash out every now and again as they get clogged up . I don't know much about them to be honest just throw some ideas out there of possible things that might cause it to run bad ? good luck with it .

They should only be used at standstill (try whacking the throttle wide open at 70 then trying to see the colour of the flame.....) & at tickover or slightly above, so only really any good at setting the pilot screws, which have a stock setting any tweaks can be made by ear.

I have used one many years ago with great success and I think my teenage son will like it and find it useful as he hasnt learned about setting up carbs in his bike mechanic education yet so this will help him I think...
As the bike has stood still for a year and not been thrashed yet , I am almost certain its the CDI.
I explained to my son that I could be wrong and it wont hurt his bike fitting a brand new one.
I have spoken with a CDI specialist that Nick in Brum suggested and a guy in Holland.

The guy in Holland said it will cost £150 to make a new one and the guy in England suggested that he could check the CDI and re-wire his generator for less than £100 and that he can check the generator against the CDI power curve to make sure he gets it spot on.
I wanted to take them off this weekend but my son has gone on a free trip to Milan to the motorbike show and left his dad all alone on his 60th birthday......:(:(:(
