Standard plug is ngk b6hs. You should probably get the b7hs because of your mods. If you are in a very hot climate b8hs.
You probably already know this, but if not just be aware that the numbers on the micro bits do not coincide with the numbered call out of the jets. The bit # is just a indexing # indicating a measurement that it's number does not equal i/e a #72 bit is .0250" or .64mm. where as a #72 jet is .72mm. So if they don't call out the equivalant in mm you'll have to mic the bit to get the correct jet size. You should mic them anyways as the cheap sets may have the bit in the wrong place in the holder.Thanks for the info, I went ahead and ordered a 4 pack of the b7hs plugs. Along with that I also ordered a micro drill bit set #61-80 wire gauge and some solder to downjet the idle jet, f*** paying $5/jet when for about $10 I can have the supplies to make any jet 36-100. Also nabbed 10ft of #41 chain, a cnc adapter 44t sprocket (started drilling out my dished 44t 9 hole but I'm not confident in getting the chain to align, my adapter is set for flat sprockets) and some locking forceps to do jet work (damn broken petcock). Also grabbed a set of main jets 70-80, $12 for 5x beats the hell out of soldering/drilling when possible.
Technically speaking, no matter what I do I'm in violation as this is 66cc and more than triple the 1hp limit. Hell, I'm probably not too far off of the limits of a motor driven cycle with how much power this zeda motorsports engine has once kitted with an alright mz65, a 19mm PHBG carb and a massive intake manifold. Once I get this carb fully dialed in, I want to grab a high compression head then eventually grab a windowed piston/reed.Motorized Bicycle (hereafter referred to as MB): No operating license is required, nor is title, registration or insurance. MBs may use bicycle lanes per 2516(6). However, MBs may not use paths because these are generally not “designated for the exclusive use of bicycles” [upon reflection, that struck-through phrase is a misinterpretation of 2516(6). It seems to me that that section *allows* something; and to say it prohibits other things may be logically incorrect. Many cities do prohibit MBs from shared use paths]. The motor is limited to 48cc’s (which begs the question about an electric motor, was that an oversight? Tuscon’s ordinance DOES include the 1HP electric limit). In other words it is treated just like a bicycle would it not be for the following phrase: “operated at speeds of less than twenty miles per hour”. No Insurance is required per 28-2516(7), because Chapter 9 is the insurance chapter of Title 28.
Moped: A motor vehicle operator’s license is required, but it can be any class — unlike more powerful cycles where a class M is specified. Title requirements are waived, required license and registration are inexpensive and fixed by statute. The power requirement is more specific: < 50cc’s AND < 1.5HP AND < 25 mph at 1% or less grade. Mopeds may NOT be operated in bicycle lane or path. ADOT says that insurance is required for mopeds (but not for motorized bicycles); I cannot find any statutory basis for that conclusion — see the analysis here, which revolves around the fact that both motorized bicycles and mopeds are both defined by statute as types of bicycles.
Motor Driven Cycle: IS a motorcycle, but the motor is limited to 5HP. As such, a class M operators license, and title/insurance/registration would be required. There are a bunch of equipment differences, seems to mainly revolve around headlight requirements. They may be restricted from controlled access highways.
Motorcycle: No motor power limit. Class M operators license, and title/insurance/registration required.
