Need some help here. Have the stock carb (cvk?). Picked up an R&D flex jet online. Supposed to work on all Keihin carbs, however it says on the package all Keihin FCR-MX off road carbs when it arrived. took the stocky screw out and compared and the needle tip designs are a bit different and threaded sections are not exactly the same and i didnt want to screw something up. anyone using one of these or tried them?

Can anyone recommend a thumb screw type if not, and does anyone want to buy my flex jet if it wont work???

Thanks
Matt

 

Good Back Up Plan Matt

 

I like the kouba screw, t handle. Think they are easier to use than the **** style because you can just push or pull on the T with a finger or screwdriver, a **** you need to get both fingers in there.
