Yamaha RD, R5 CDI Ignition-12v/150W, 71-05-799-00

I've been wanting this ignition for awhile, and finally pulled the trigger. Really wish I got it sooner. The install was pretty easy, had to do a little fabrication with mounting the ignition coil, but well worth it. Super strong spark, and the bike runs noticeably more crisp. Battery charges at 14 volts. I also paid extra extra for the keyway service because it seems silly to me to have a keyed crank but not a rotor, in my opinion. A+ product.

Very well put together kit that is easy to install. This kit worked so good on my ds7 I bought another for my rd350.

Installation went smoothly & only required some removal of material from outer cover to make clearance for the new system. Overall very satisfied. No more anemic ignition system (points & condenser) & charging system. Starts on the second kick & charges 14 v consistently. Additional thanks to Brad for his helpful customer service.

I'm still in the middle of my rebuilds I haven't tried it out yet. However, fast shipping even during Christmas time. I fitted the ignition in my DS7 and it fit well. I did have to remove some material inside of the cover, more than1/8 inch to make room for the corner of the pickup coil. It was easy use a dremel tool or similar, don't be afraid not a big deal. Now it does not touch the inside of the cover and I have plenty of room to set the gap at .5mm. If it works as well as I believe it will, this investment will be worth every penny not having to deal with obsolete and hard to find ignition parts. I will update this spring when I'm up and running.
Cheers!

Good spark, can open plug gap and lights are much brighter than stock.

After some setup issues (mostly my fault) The system works great and the bike never ran better. The guys at HVC offered great support on the phone.

I have the Powerdynamo in my 75 RD350 and both my 77RD400s. Also installing in my 72 GT380 project. This is the only way to go, a GREAT product. Do not own an RD without this system.

After having diagnosing charging system issues I decided to order a powerdynamo instead of spending money on oem parts and still having a marginal at best charging output. Istallation was easy, (I opted for the keyway cutting option.) Charging output is greatly improved allowing me to run a modern halogen 55/65w headlight. unit starts on the first or second kick everytime. Have to put some miles on it to tell if plug fouling has been eliminated. Runs great, money well spent!

I installed an early offering of this ignition. had some minor fit up problems with the mounting bracket holding the pick up unit. Brad with HVCCyle was great to work with to resolve the problem and the issue is not existent with current offerings. Up and running the unit works great. I am actually using a 65W head lamp with no issues. EASY starting and I do not fowl plugs any longer (Much stronger/hotter spark I guess). I HIGHLY recommend doing the option for a Key way. It took me a while to find a Loctite compound to keep the unit from slipping out of timing (Bike would actually start with the motor rotating in reverse). The unit is well worth the money, it eliminates all the timing and charging issues of the stock system.
