2007 TE 250 to 310 jetting

In search of a little more poop for my 07 TE250 I ordered up a 310 Athena big bore kit from Edgar at ECbike.pt. He gave me a great deal on the kit too.

So with the 300cc top-end I’m wanting to get some base line jetting to start with. Also with the head off is there any cam timing or other secrets get a little more out of this mini thumper?

Really? Know one has done a 310 kit on their 250?

My friend did the kit on his 2007 TE 250, he likes it a lot. The kit cost him $525 with shipping. The power was better all across the range.

Why couldn’t Athena CS give you some info.? I had one on a 2008 injected 250 TE. The Athena ECU piggy-backed onto the Husky ECU and somehow George (Erl) @Uptite got it to communicate with iBeat and I remember the FB 1 was 127. 50 cc’s i a 20% increase anyway.

Thanks for the response and that sounds promising. Just what I’m looking for! I paid even less for the kit which I’m greatful for!

If you have a chance to ask him what he did as far as jetting that would be great. Ty

Mines a 07 so last year for carbs.
