Re: NEW CARB :D

Hi
Good carb. but do you have the adapters for the front and rear ?

Some has already done the change of the travel limiter of APJ to that carb. Do you know how to set it ?

How about jetting ?

Re: NEW CARB :D

Woooa I didnt even know about the adapters ). I knew about ONE adapter which is for the "airbox" but I didnt know you had to change the one which goes into the engine as well(must have misread in the owners doc). I also bought a gas throttle with dual cables. The jetting stays as it is for now, will see how it runs, but will definitely change it for the next season, during the winter at some point.How do you set the travel limiter?

Thanks, Tom

Re: NEW CARB :D

Sooo the adaptor is ready .

I tried it on today but it has a very nasty leak from the o-rings at the gas "pipe". I dont know its name, it's that copper thingy where the fuel line goes, it has 3 o-rings on it. Will fix that tomorrow. Also I have to run with one gas cable since on of the dual lines moves very hard and the slide doesn't close correctly because of this.

Re: NEW CARB :D

Hi Tamas

You've found a nice adapter for the rear

For the front please don't do the same !! Some people like to cut the dellorto rubber, but I don't like that, already had bad experiences with those. My advice is to buy to aluminium adapter for the head and the newer rubber.
Anyway when your dellorto rubber starts to crack and you want to exchange it you won't find a new one, so you better do it right now.

Re: NEW CARB :D

I may sound stupid but I really don't understand why I need to cut the Delorto rubber or to change it? It seems to me that it fits perfectly as it is. At least in my case...
Today I went out for a test drive, starts easy cold, and warm as well. Starts on the button as well. Goes like a poisoned rat also, but I get the feeling it is a bit rich on mixture. The reason why I think that is because it starts without choke when cold and I get a slight hesitation when I mad the throttle suddenly,but only on lower rpms. Other wise it seems fine by me. It really is a massive difference compared to the Delorto, mostly in how precisely you can put the power to the ground and also it doesn't vibrate as much. I was really surprised on how well it behaved without any sort of adjustment whatsoever( except the idle).

Re: NEW CARB :D

I'm interested in knowing what size carb you are using and what did it come off. What about jetting are you using what it came with or did you have to change it?

Re: NEW CARB :D

The carb is an FCR 40 mm and from what I was told, it came off of a WR450 from 2006, if I recall correctly. The jetting is probably standard, I didnt take it apart to see, I just fitted it and "wroom wroom" ).
