The other night I finished my first 4 valve conversion. I recorded the whole process but am not done with editing yet. I will add the videos in the coming days...
The kit I purchased was a Taiwan kit, but not the Taida kit. I also own the Taida 4 valve which is a higher quality and comes with all the right stuff, unlike this kit... For those who clicked the link you will see it comes with 4, 213mm cylinder stud screws, but only 2 are the right size. You will also need 2, 218mm studs. I acquired them from a Taida 218/225 kit. In addition, you will need to increase the chain to a 46 (aka 92) link chain.
The other upgrades Consisted of a 58.5mm BBK bringing it up to a 155cc, installed an 11 pole stator, Hoca Premium Gasket set and this Taiwan CVT set.
I fired her up and after finding the right Jet setup (#35 and #108 in Keihin PD24J) she runs smooth as butter and in my first test runs I hit 58MPH and was only at 6000RPM's with plenty left to go... I can't really get into her until shes gets broke in.
The components were around $300 with another $25.00 in gaskets and various other materials. It's one of an upgrade without having to cut the case....

And here's a video of me starting her up:
