BUY THIS NOW! I have no regrets, this kit is amazing, amazing, can tell the difference after installing. I had great support and help through the buying, delivery, and installing, and I honestly wish I had done this sooner. And honestly, guys, get this. Ride safe fellow riders!
Just upgraded to these 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
Get these NGK HT Leads everyone, in Combination with the Laser Iridium Spark Plugs, it makes a difference, she runs a lot smoother, better Throttle control and idle
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.

Admin Reply: 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!
So got this set few weeks ago as i wanted a bit longer gears. im using it in city, heavy traffic, daily commuting. Before was changing gears like a lunatic 1st to 4th non stop.. this set sorted my problem a lot to be fair. 20-35(40 with screaming engine) mph in 3rd gear. 2nd gear comfortably around 25.. unfortunately havent tried whats the max speed now as grown up life sucks and havent had time to push the bike yet
