Starting 4 valve engine with ease from OORacing

Hello
This is a short video of me starting the 4 valve high compression engines, it proves that when started in the right crank position they will start with ease and without any chance of a kick back or setting off the sheer gear.
We get a number of call saying the engines are imposable to kit over, but that is only due to they are trying to kick them over on the complete compression stroke.
Please watch and take note of the following
Don't use the choke with any of the carbs out there and use the idle screw as the choke by turning it up ½ a turn from its normal running.
Always do a trial kit with the ignition off just to make sure the bore is primed/clear of any excess fuel, do this on start up each time if left for more than 30 minutes.
Never open the throttle on start up.
Always warm the engine up on a fast idle for 3 to 5 minutes wit out blipping the throttle.
We hope this helps

I found this head can be high maintenance with the valve shimming but love the note the engine puts out at idle and high rpm, sounds exactly like my 150 yx 4-valve bitumen racer, check this link of me racing my 4-valve if ya get time watch?v=MaDhczv27hM
