[JhallettEX]

After getting my JE 416, and my xr400 cam I will have about $300 left and I want to sink it in my engine. What else could I do to ensure that i will have a winning quad for next season? Thanks alot for all the help.

new carb, id go wit lectron, eddlebrock or klien FCR

[JhallettEX]

I am playin with that idea but wanted to know what else was out there that I could do. Thanks, Anyone else.

... and buy an FMF powerbong header pipe. You will not be sorry!

[JhallettEX]

Will that work with a WB E-Series pipe?

Knighttime beat me too it,,,,I was gonna suggest the powerbong also,,,,,and yeah it will work,,there are few guys out here running a powerbong and E-series muffler.

You'll also have about $100 left so get ya a CR perch and lever, pro design kill switch, and some fancy billet aluminum parts from redrider ex..:D

[JhallettEX]

Allright, I allready have a CR perch and lever and a kill switch. I will look into the powerbong. Anything else I can do?

Port your head

[JhallettEX]

Ok this might be a dumb question but what exactly is porting your head....I think that it has somethng to do with air flow, Correct? Who can do it for me? ( A local machine shop or what?) What kind of increase in performance will I get? Thanks alot for everything guys.

i would get porting and ur carb mod it cost me 300$ to get these both done... portin ur head is they clean out where the air goes into and out of the motor they make then bigger... and then they polish it out so the air flows better.... my carb is ported and polished to its got like a tornado effect to it... hope this helps....

It is a good use of money. If you really want to utalize(spelling) that piston and cam, a ported and polished head would help out a lot. Any local engine builder could do it for you.

There is no use for porting unless you have a modifyied stock carb or an aftermarket carb. Porting is a waste of money untill you get a carb.

[Tommy 17]

a guy named rob gremly did it for me cost 80$ i dunno how big of a gain it gave me bc i did it all at one time with the piston and cam... now i just need my pipe...

[Honda Guy]

Will you feel a big diffrence without porting the head and just getting the carb? Whos carb is the best?

Oh yea. I'd get the carb then do the porting later. Then you could give us a report on how much power gain you got. Get a 39 mm FCR. There was a report about them in some mag i can't remember which.
