| | Carburetor pictures how to install and rebuild Pictures from taking the carb off the bike and taking it apart to puting it back together and some info. on how and what it all does well sort of and ways to change the main jet for those who want to and areas that can bite you by plugging off and sort of how to fix them. I hope this will sort out your questions if not let me know. I think this is a very nice and simple carb I think its great some of you hate it, can't make everyone happy. Here's the pictures.
The pencil is pointing to where you can turn this out and take up some of the slack on the throttle cable.

| | Re: Carb pictures how to I wanted you to see the IDLE SCREW and the little throttle slide guide and the fuel tickler, push it down for a few seconds and it lets fuel in the carb for a cold start along with using the choke. I don't use it myself.( the tickler)  |

| | Re: Carb pictures how to .026 is stock dia. of main jet on my carb to go leaner solder shut and drill smaller my suggestion is one size at a time ( what affects wide open throttle is main jet dia.). Most adjustment can be made with the e-clip on the needle. This mostly affects the less than wide open area of throttle. If you can't get it tuned with the e-clip and want to go richer make sure of your stock size then drill the next size bigger then test your bike. I have found some other carbs have 0.025 main jets.
I've also found that if the needle is not tapered or taperd properly your engine will not rev up ask Pablo. you can measure the taper at the tip by the grooves it should be arond 0.070 and down at the pointed end about 0.068 or so more taper the richer it will get you can ruin it in a heart beat by sanding it but sometimes you have to do this by chucking it up ina dremel and use 600 wet/dry and very lightly spin the needle while holding the paper to the needle check it often and try it in the bike until you are happy with it or ruined it and need to get a new one. Dam I hate it when that happens.

| | Re: Carb pictures how to pointing to the place where if you get trash in the tank if you do not run an inline filter this is where it will get to first and cause the engine to flood you got to take it apart to get the dirt/trash out. this can be removed by taking off the fuel line and unsrcewing the fuel inlet pipe carefully and don't loose the red gasket hard to make and will leak if you mess it up.
