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 ๐
Bike is a 2003 gv250 carby model
Great item arrived well packaged and quickly loved the little notes that Marcel put on the items like the torque pressure thankyou so much hopefully it means I will be able to get my bike back on the road after failing itโs mot
Wow such a huge difference, finally changed this myself. Not too scary. Straight swap for old kit. Didn't even need a gasket. Much sharper gear changes and acceleration. I highly recommend. On a scale of 1 to 10 it's about a 6 in mechanical knowledge. Remember to soak the plates and don't over tighten the bolts. It's a full oil change so have at least 2 litres handy
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!๐ - 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
Got a set for my project bike a 12 front 48 rear on my xrx125 and it has made a lot of difference to the way the bike rides, it's not a gear setup I got for top speed I wanted more acceleration so went with a 12/48 set up now the bike not only holds it's top speed but I am able to go up hills or against head winds without changing down a gear, I can even accelerate up hills and change up gears that a normal 125 would struggle with.
Apart from the way it helps the bike run, the look of the new setup is so much better than the stock setup.
I can't say how long it will last as only done a couple hundred miles, so far it looks good.
It's a simple upgrade that's worth the money
