Derbi break in

I finally got a chance to take the new derbi out for a ride. I have been starting it on the stand and letting it warm up for a pre break in. I started it tonight let it warm up and started going around the block and the pickup is insane. Never felt that much power from a moped. About half way around it makes a weird pfffffft discharge noise stalls then starts right back up like nothing happened. Is my decompression valve not adjusted and could it be leaking.

It has a new Metra 65 with a 16mm Dellorto PHBG Zen pipe and a TJT setup

just curious, did you go cast iron? Derbis are awesome, but i'm not sure why its stalling. Make sure the decomp is adjusted properly

Re: Derbi break in

It's not the cast iron kit. Whats the best way to set the decompression?

Re: Derbi break in

Mine did that when the condenser went bad.

Re: Derbi break in

Are you running flat / pyramid / or piston port? And just curious what jet do you have in there?

Re: Derbi break in

Flat reed nikasil kits come in 65 and 75 zack.

I doubt the decomp has anything to do with it. Just leave a little slack in the cable and it will be fine.

Mike is right, check your ignition system.

Re: Derbi break in

Flat reed I think its an 84 jet

yea vic, there's three cylinders, one cast iron and 2 nikasil. I've been eying the cast iron for my herbi build, but thats off topic here.

to big of a plug or point gap

Re: Derbi break in

Going to upjet, the plug was just a little to lean then reset the plug gap. Are the condensors the same as Puch?

Re: Derbi break in

just run an external condenser from napa.
