Nice kit ! All you need for more power. Fast delivery in France. Good communication with the seller ! Highly recommanded for your tiny V twin Jeff

Item arrived quickly, with everything needed. I was sent a 13 tooth front sprocket. Have had it installed for a few days and can say while I have not seen the full speed increase (my daily commute to work is along a road with many declines and inclines) I can say that my commute is a bit quicker with this installed and I have seen higher average speeds overall. Also taking off from a stop feels better with the kit installed too. Have seen about a 3 to 5mph (speedo) increase in the gears 1-4. First time installing something like this I had all the tools needed (torque wrench, impact gun, socket set and hammer) had it done within 2 hours having read the instructions the day before so it was a straight forward and logical install (mostly need instructions for the torque specs). Only thing I had help with was holding the rear brake while torquing the front sprocket nut. Only complaint about the kit on my bike with this is that the chain adjustment needed to be set close to the maximum adjustment to remove excess slack in chain. If I have the bike when it comes time to replace the sprockets I will be purchasing this kit again.

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

MARCEL ROCKS! Not only is this kit is a must have upgrade for your bike, but the support and advice i've got from Marcel is amazing! You should now that this is my first motorcycle and I really love to make my hands dirty. I love my bike but the acceleration was a bit disappointing. I've read about a tooth more or less on the front or back sprocket, but i really didn't wanted to loose any top speed. It seemed to be one or the other (more acceleration more top speed). I talked to my dealer about this, but I didn't find any help there. So I contacted Marcel. He sent me the kit and the delivery was very fast (I live in Belgium) Then came the moment of truth: would I be able to do the upgrade myself? I succeeded with easy with some remote support from Marcel over messenger. His reaction time was very fast and I didn't loose time with the procedure if i had a question. Many thanks for that Marcel. The day after the installation came the second moment of truth. Would this upgrade perform as advertised? In short: IT DID! The test ride with these sprockets / chain exceeded my expectations . The acceleration in gears 1-4 is superb now. In second gear i can pull up to 50km/h - in 3th to 70 km/h without going in the red range! The bike pulls really fast now. About the top speed, with original chain kit my top speed was 107km/h on a steep downhill. Now on a far less steep one i reached 119 on display and gps speed was 107 !!! Speed record easily broken.

After a little bit of a struggle I finally got the kit on! Thanks to the forum post that front sprocket was a right ass to get off! The bike feels much nicer to get up to speed, it feels a lot smoother and nicer to ride! So far I’ve noticed an increase of about 5mph on the top speed but I haven’t pushed it to see how far it will go but that extra 5mph gives a more comfortable carriageway experience. Highly reccomend!

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
