Another great upgrade Marcel Thanks. Since fitting this I couldn't believe the difference! Engine fires up faster, idles steadier and no more bogging on the overrun! I think it pulls stronger too. I'm sure this will cure the higher speed fuel starvation problem too. Worth every penny.
Where do I start? The beginning I guess 😉
I bought this Beauty, a GV125-S last Month and was not happy with the Power and acceleration, or should I say missing Power of the 14 PS compared to my last ride a Yamaha XV 125 with 11 PS.
Dont get me wrong I noticed the difference, but she was just laggy, screaming at me, and the Vibrations when going above 8000 Revs. In 5th gear she hit 10-11000 revs and just stopped power wise, not going any faster than 105 Km/h on the dial.
In the German Group on Facebook it was suggested to upgrade the front Sprocket to one with 15 teeth, which I did, She run a little smoother through the Gears and the Engine sounded a bit quieter and wasnt screaming at me, but the loss in Power in the lower Gears, especially going from 2nd to 3rd, and the Top speed of 110 Km/h, which took me ages to get there, wasnt satisfactory, taking her up into the Red again to get here..
Then I saw Marcels post in that Group and decided to buy this Upgrade from the UK and have it shipped to Germany, thanks to Marcel here for the support.
What can I say? I took her out on a 3 Hour ride to test, what a difference!
The smaller front Sprocket (13) and the Larger Rear Sprocket (Dimension) and 520 Chain is the perfect combination.
She shoots up through the Gears, no Jerking, no screaming Engine, next to no Vibrations, just smooth and fast, at 9-10000 Revs in 4th Gear she hits 100 Km/h and in 5th I had her at 120 Km/h and felt like there was still more .... plus it was a windy day 😉
I also ordered the NGK Spark plugs and HT leads which just finishes off a perfect combination.
Thanks Marcel and Team, Season nears its end and I just cant wait to get out there next year, the Bike is so much fun now and I dont miss my Yamaha at all 😉
Ordered these from Norway. Fast delivery and fantastic support from the team. Bike start much easier and feels snappier in the throttle response. Fitted this together with NGK Caps and Iridium spark plugs.
Came to Spain very quickly. Excellent kit. Spain being a bit naughty with customs since Brexit, or it may be because I use a private post box! Not bad though as I had €100 of parts and they only charged €10.
