I’m pretty happy with the big bore kit and exhaust on my Chinese scoot. It is just a TaoTao VIP50, but I replaced the short case with a long one from a wrecked scoot, so I could get some more wheel diameter for a better ride. I would really like to put Zuma-sized tires on it. Have any of you fitted 130/90-10 dual-sport tires on a long case 50cc GY6? I know they will clear the fork, but the CVT case and shock look a little close for comfort.
I can currently max out my tach and speedometer at the same time, but it feels like there is more in there. I don’t want any more speed on those tiny, skinny tires, but if I could get some honesty from that speedometer at 10k, that would be good enough for me. Maybe the hot cam and PWK carburetor as well at some point.
Put the back tire on. It just barely clears. I went for a ride to compare top speed before the front one changes the speedometer reading. The zippy acceleration that I had come to love is gone, and my reward is that it hits 50 indicated, so 40 at 9k instead of 10k, but it lacks the oomph to get up to 10k. The riding experience is worse. No doubt hurt by the extra rotational weight of these big tires. Even if it could run out to 10k, maybe that would get me an extra 5mph. If I can get some more power out of a cam or PWK carb, maybe this will be an improvement if the ride is better on big tires.
If you need some tires . I can hook you up 130 90 10 brand new and 120 90 10 lightly used These are on on road off road type for the zuma
Hi Zino. I know this thread is a few months old, but I came across your post while trying to research tire options for my '05 Zuma. I've finally got it running decent (and installed Polini Contessa bbk) and looking to replace the old cracked tires. Are you still looking to make a deal on these tires? Thanks. Sorry for the highjack.
The kendas would work well for you Do you have the tools to change them yourself?
Well, I've got tire irons, a compressor, and ratchet straps, but I'm a bit apprehensive trying to change tires with such small diameter. I've done changes on my dual sport a few times years ago, but those were 21 & 18 inch rims.
Soapy water soapy water soapy water... or another lube of your choice.
When I changed a tire, one singular only, I ended up standing on the tire while attempting to get it over the edge of the wheel. I had made sure the 'other side' was as deep into the wheel as I could make it. Adding a soapy water solution made all the difference. It was not easy, but much more 'doable' with lube. It is a PITA. I used adjustable wrenches - the handle end - as tire irons. Though thicker than real they are all I have that had rounded edges which I wanted to avoid pinching and damaging the tire. Have changed tires, added & repaired tubes in the front and rear wheels of a riding mower. It is about the same thing, a PITA. I guess people find it difficult enough that you can readily find pre-mounted tires for many models. One firm, Carlisle seems to have cornered the market on replacement OPE tires. Sure seems they are overpriced, and likely have gone up significantly since I last replaced any. Back a few years, it was $50 for about any rear riding mower tire. Unbelievable that a 12" low speed, 2-ply thin tread tire can cost that much. Does Kenda make any that would fit riders? tom
It's not how hard you work, it's how much you get done. simplificate & add lightness
