There are issues with posting delays lately as a result of both limited air transportation and changes in how postal operators deliver. That said, I always do my best to have any orders delivered back as soon as possible. Here are a few units that I received, repaired - modified and delivered back within 48 hours. A Honda Rs250 NX5 PGMII for Oliver(GB), a Tzr125 YPVS controller for Simon(GB) and a Rd500 YPVS unit for Tony(USA). Thank you all for your understanding. Nick
Most PGM units now have almost 30 years of use and ignition fail is a thing to expect. Aged parts and drained capacitors have a lot of side effect as well. A PGM unit with low miles puts out about 300V DC to the ignition coils but most of them rarely exceed 280V DC. All PGM3 units leaving the workshop put out 320V DC and the cleanest possible waveforms as they were intended when they left the factory. On a well serviced unit you will immediately notice easier cold starting and a crispier sound and you haven't even ridden the bike yet! Ps. Fourteen PGM units with ignition issues, all repaired and I now have to proceed to Rc Valve checking and repairing, a couple solenoid issues etc. but that's the easy stuff. Thank you. Nick
The below ypvs exhaust curve was stock on John's(USA) '86 Rz350 bike. I'm not sure I've seen this curve in the past. The exhaust valves starts opening at 7.000rpm and are fully opened at 9.500rpm. A few photos of John's RZ bike.
Here's another one ultra rare PGM unit that belongs to Pomper(NL). This one is a reprogrammable PGM unit for the late Rs250 bike. Yes, you see correct, it's a PGM3 and not a PGM2. Even though the internal is quite similar to the usual PGMIII unit, the pinout is totally different.
I've been working on some YPVS controllers for Pete(GB), Gavin(GB) and LES(CA) and I just found out a new exhaust valve curve that I want to share. Pete owns a Tz250H converted to an L (electronic power valve). I have a few TZ250 (mostly reverse twins) exhaust valve curves on the blog but the below one is new to me.
Many thanks to Paul(USA) for the photos of his Nsr250 and his kind words about the Battery Eliminator. I purchased your battery eliminator for my NSR250 and it works great. Bike starts easily every time. Thanks, Paul
