Well I got my 2004 FZ1 to make 142hp to the rear wheel. 66 cubic inches with CV carbs. Pretty low performance I would say..

Have you ever thought of using a CV carb. Something like in the 32~34mm range?

Stop dicking with the plugs.. https://www.14point7.com/products/sigma-lambda-controller-free-2 If you are insistent on reading plugs get some real leaded ethanol/MTBE free fuel so you have something to look at..

n2O... Here is a suggestion.. get it running.. in something.. tune it/get the bugs worked out.. then feed it the N20.. And use a real system like this https://www.holley.com/products/nitrous/hidden_systems/parts/05029NOS I foresee "Hemi build #3" real soon.. :thumbsup:

Is it done yet?

I have a question about that flywheel... Is it machined for the correct taper for the 60363 Predator.. I know the taper is different from Honda GX/other clone engines.

Yes and No... Quench, swirl, tumble can increase the speed of burn. Sometimes you have to pull timing back near the rpm limit.. The only way to optimize timing is during a constant load on a dyno..

The time it takes for the coil to saturate and create a spark is relatively constant. As an example say it takes 6ms for the coil to charge/discharge with a spark. At idle the amount the crank moves in 6ms is very small then when at 8,000rpm.. Points or a transistor trigger sometimes are not...

So Bob,, why does the timing retard with increased rpm?

Holy valve shrouding...

http://www.14point7.com/ If you like to tinker.. I used of few of there products..

I assume its is a 212cc.. Post a pic of the rusty cylinder wall..

this is the one I use http://www.nrracing.com/product-p/qmnrr-7.htm

I was asking if the oil smelled like gas because a flooding carb (bad needle and seat) will slowly start to fill the crank case. The grossly over filled level will "blow" oil all over the engine.. If you pull the dipstick/fill and the oil comes gushing out it may be a problem.

Does the oil in the crank case smell like gas?
