Hello there, I recently installed a reed valve on my 49cc two stroke engine, previously it had a boost bottle in it from BIS-Racing.com and it worked pretty well and then I read about on Reed Valves and all of its pros and cons and decided to buy one and install it on my engine.
And after running the engine with the reed valve installed it has half or even less power than it was when the boost bottle was installed. With the boost bottle its an easy 40kph, with the reed valve it barely goes up to 20kph. (BTW my bike is a motorized mini velo with 20inch wheels and im usng a 36 tooth rear sprocket). I read on some articles that you have to have a rich mixture for it but checking sparkplug its all black and sooty so meaning the mix is still rich. How do I solve this?
BTW I done some mods on the bike
1.) Dellorto clone Runtong carb with #70 jet
2.) custom exhaust
