Just upgraded to the uprated coils, the uprated regulator, the uprated stator and ngk caps with iridium spark plugs. I have to say it made an amazing difference, the bike almost no longer needs choke (less than a minute and only on first start in the morning), acceleration has improved significantly and my bike is now charging (which was my original problem :p). Very happy with all items 🙂 Bike is a 2003 gv250 carby model

Life changing part of you are looking to change coils. I’ve put my new coils through a lot during the problematic idle and power problems. Works so well with the regulator you can purchase here. A total must have.

Great upgrade, highly recommend!

Top Quality , improves performance and tickover.

Fantastic service from marcel. Brilliant bit of kit and would recommend anyone looking to upgrade to buy this kit.

Arrived super fast. Plugged in my 125p started the engine, took it out for a ride, amazing indeed, instant noticeable improvement to start up, idle, throttle response 🤗 perfect. Thanks.

Logged a few hundred miles since the upgrade. Here are my thoughts.  This brake system upgrade is the best value for money spent since I bought the bike. Dramatic improvements in overall stability, high-speed handling, and low-speed manoeuvring. The Hyoriders club may have saved my marriage.  This is my third attempt to write a product review for the stainless steel braided brake lines. Hopefully this time when I'm done I don't hit the wrong button. I don't really do product reviews. Either the thing works as advertised or it is sent back.  I am taking the time to review the braided brake line kit because Hyoriders shop has been the best customer service experience in all of the thirty years I have been riding motorcycles.  I ride a 2008 Anniversary Edition GV650 efi. It was love at first sight and I paid cash-in-hand. Soon after it became apparent she had not been properly maintained by the two previous owners. I struggled for ages to find legit OEM fitment parts & upgrades. So much so that I've been ripped off by a couple of sites claiming to be licensed distributors.  Hyoriders to the rescue.  There are plenty of bad faith actors out there and my wife and I are really glad I found this site. There are loads of tweaks and mods that provide wee little improvements in performance.  I do love my X-Ring chain conversion and everything else I've bought here.  However, this brake system upgrade is the best overall performance per pound. I now know that if I can only afford one performance upgrade on a bike that it will be stainless steel caliper pistons and steel braided brake lines. It really isn't possible to explain just how much better planted it feels in the corners or the effortless low-speed city street and/or carpark handling. I could try to remember everything I said the first couple attempts to write this review, but I'll just leave you with a couple of observations.   Caution: Take the time to talk with your mechanic to clearly communicate how you want the brake lines routed. Ensure you have all the nylon P-clips or zip-ties, or whatever mounting hardware you prefer for your desired finished look. Confirm with the mechanic where the lines will be routed and how they will be attached. Five minutes, or less. That's all it takes to be certain it looks the way you want.   Also,  Are you running OEM or after-market / reproduction calipers? If so then please ask about a stainless-steel caliper piston rebuild kit to go along with these awesome braided brake lines. Sincere thanks to Marcel and the entire Hyorider team  -- Cheers, Chopper Pearson In all things, Endeavour to Persevere

Instant gains from this kit amazing worth every penny

Been driving with this for about one year now, and it is amazing how these changed the spark characteristic on the bike. Great product.

I've added this upgrade onto my bike it's perfect only thing I found was that the front sprocket was a little loose even with the washer. I'm hearing some noise but unsure if it's the upgrade so I can hear the chain go more now if if there's a problem. ============== <strong>Admin Reply:</strong> Thanks for your feedback, glad you love it like others do!💎 - If your font sprocket has a rattle, please investigate your drive shaft itself, we don't know if your own previous sprocket splines caused any issues to it etc, remember the original OEM sprocket from Hyosung is made in China, another owner made his bike chain adjustment too tight and he lost his engine shaft, so it was a mess! (his own fault) but the original sprocket was badly worn even inside the spline teeth connecting to the front engine shaft , so double check your setup! Remember to check chain slack and keep it lubed well!
