I agree with the real results comment, nice to see actual numbers.  Really nice looking bike Chris the colours are sharp and allot of attention to detail.  Does LED sell the graphics kits?

Yeah, people throw the 70hp number out there like its no big deal.  That is a hard number to hit, I am sure that thing is a blast to ride with those numbers.  Beat up on stuff that never saw it coming!!!!!

Can you tell us what kind of jetting you are running and what the timing numbers are with the CR ignition. I have a feeling it will suprise people how small of a main it's running and what needle

The only thing I don't like about this quad is, I can't see the other side!

We run a 52 pilot jet, DEJ needle 4th from top clip position, and 178 main jet. We optimize the timing by adjusting it on the dyno.

How would a slightly built 450 compare to this in hp and torque? Say just a cam and pipe or mild port job.

Those are some nice numbers.  Love the tq.  over 40 ft lbs for 2500 rpm.  

Do you have any dynos of the 363?  

Good work Arlen.

Nice Work Arlen! Good Acceleration, wide power band.Very good numbers! Am I correct in stating this would make a good MX motor as well ? What is the LED Low Port ? Is this where the bottom of the cylinder is machined to bring the Port roofs down to get the required Port Timings ? What are the Ex & Transfer timings for this motor ? Is the pipe an LED Adjustable pipe ? Is it adjusted all the way out (lower hit) ? Sorry for all the questions but this is the exact type of build I want for my 330R. (maybe not quite as much power)

Thank You for sharing :)
