Hello folks, I have tried all of the options above and in the videos and am unable to get an accurate rpm reading. With the universal gauge set for '2 cylinder' and wire connected to the yellow wire from cdi I'm getting approx double the rpm that I can hear (it's reading 4k but sounding like 2k). I've also tried setting the gauge for '4 cylinders' but then get an even higher inaccurate reading (reading 7.5k at the same 2k). I'm beginning to think the gauge is faulty. Are there any other possible connections you could suggest?
I'm going to share my thoughts because I've spent many hours reading and searching.
Maybe your gauge is faulty or there's no settings for the waste spark system. If it's the one I think it is there are so many bad reviews. You'll find them on Amazon, Ebay, Wish, Aliexpress... they're all the same and you need luck to get a proper one. Somebody bought 3 of them and all were bad but I think it's mostly the speedometer. Some works good, some for a while and others doesn't work at all.
Before buying cheap products from China I always watch alot of videos, read comments and reviews and I don't trust good reviews were you can't update it since many ppl give good review right after they've got the product without testing them much or at all.
Anyway, do your own judgement.
If I lived in the USA I would probably get these (link below) but in mph. They come with different ratio, km/h or mph. You can find the same on Ebay that are extremely cheap but are they just as good?
Maybe, maybe not. I've read good reviews about the cheap ones but I'm a bit sceptical since the cheap ones in km/h only goes to 140 instead of 220 km/h. It means they're meant to be in mph which are 140 for this model.
