anyone here has had experience with the hrc card conversion also what is required to make it work are you required to rejet the carbs and if so is there a base setting will it run fine with std exhaust or you need aftermarket also what kind of coin you think they go for is it a easy install for a novice thanks in advance
Bit late to reply Noah but here is what I run: HRC030 PGMIV (for 95 octane unleaded) Oil Injection Rebuilt engine with replated barrels, decked heads and porting. Tyga exhaust Tyga billet exhaust manifolds Tyga perfomance reed block Tyga carbon airbox HRC needles and HRC X/Y air jets Wiresplice The bike is putting out low 60s HP which is a big step up from the 40 odd stock and makes it a much better bike and still rideable in the midrange. The main jets and possibly needles will obviously need to change from what I have if you go premix. With oil injection, the oil is injected after the fuel and air is mixed in the carb so it doesn't effect the fuel/air ratio. If you go premix, the oil is mixed with the fuel in the tank which is then mixed with the air in the carb so you effectively have comparatively more air in the mixture as there is less volume of fuel due to the oil and the bike will run lean; so you will need larger mains and possibly richer needles. I have 155 mains (up from 140 stock) and the HRC C needles (the leanest needles of the set of A/B/C needles) set on the middle clip. With the HRC needles you will also need HRC emulsion tubes. Air screws are 1.5 turns out from fully closed and I am running stock pilot jets. The bike is probably still a tad rich at idle and up to 1/4 throttle but is pretty good overall. Next time I have the carbies off I will probably go down one size in the pilot jets and possibly lean the needles one clip and see how that goes but it's by no means a necessity. The X/Y air jets work via solenoids that are programmed to open the jets at certain RPM to allow extra air into the mixture than what is delivered from the air box. This worked well with the stock setup as the bike would run a bit rich between around 7-10K RPM without them so it greatly improves the bottom and mid range and makes the bike very ride-able. With the HRC card you need the HRC X/Y air jets as the HRC card advances the timing of the ignition. Once you get the main jets right using an HRC card, with the standard carb parts, the bike runs lean on WOT at around 7-10K RPM. The HRC X/Y air jets are actually more restricted than the stock items and allow less air in to the mixture when the solenoids open which gets rid of that lean spot. You won't have much joy unless you run at least an aftermarket exhaust, open the air box (some just run no lid) and HRC carb parts with the HRC030 card and wiresplice. Otherwise all you will get is a badly running bike with no extra power. There are two options for the card. Firstly you can get your current stock card recoded by a fellow in Japan. You will find the details on NSR World. You need to send him your PGMIV and Key Card. I think it's a few hundred dollars. Secondly, you can buy a complete used HRC030 PGMIV on somewhere like Japan Yahoo Auctions and install that. It's a lot more expensive but you will have a spare PGM. I also found the HRC carb parts and X/Y air jets on Japan Yahoo Auctions. None of them are available new anymore and you will have to do some searching. None of this is too hard to install but it will cost you upwards of 2K for the parts. The HRC carb parts in particular are going up in price as everyone wants them. Workshop manuals and HRC setup manuals are available on NSR World. It's also worth noting that you probably should make sure your engine is in sound condition before you do this as it makes a lot more power.
