Love my Piranha 140,except for the fact it kicks like a mule.I found using a squirt of starting fluid makes it ALOT easier to start.I have 800 plus hard miles on my engine and it runs perfect.72 CT70K1 with YX160cc engine
0.6kms on engine
kicked it over, split the case in two
common issue it seems
I guess I can say "you told me so"
Maybe time to start looking for a Honda Nice?
I watched a video made in China or Asia and I was just wanting to see what he was doing to the scooter motor nd got a glance at the speedo which read 23,000 kmsI received some information from someone that they have now been running a Daytona FDX190 now for over 10000 miles. They had an ignition failure and had to replace the Stator/Flywheel and the CDI box (as they are not interchangeable) and they have had to adjust the valve lash a few times (which may indicate that the valves are cupping) but the engine hasn't been apart and is not burning oil and otherwise is running great.
I have also finally got an opportunity to ride one and was very impressed with it on a street machine. It is, without doubt, as fast as my TJR176+r nice engine but delivers the power differently. The Daytona is a square motor whereas the Nice is a undersquare. I personally prefer the power delivery of my Nice engine, however when you get that daytona up above 7k, hang on! I hear, also, that the stock daytona cam is very tame.
Honestly, if I were going to build another bike and needed a powerplant I'd use on the street, I'd go with one of these Daytona's without a doubt.
Maybe Fatcaaat will chime in here... But I think 18 tooth sprockets work on the Honda engines with some minor milling.I have a question:will a 18 tooth front sprocket fit on my YX 140 engine?
Putting the 18 tooth on. YX-140 engine"hopefully" it fits.edited 7/22 it fits the YX-140 with just ALITTLE grinding on the top of the stator/ counter sprocket cover at the top,or you can move the cover slightly up in the rear about 2mm and tighten bolts,this will keep the chain from rubbing on it.Fatcaaat has run sprockets as large as 19t on the countershaft. I've gone as big as 18t. Those were on Honda Nice motors and even then the fit is not what I'd call optimal. With 49c-based engines, I'm not thrilled going bigger than 16t. With the Chinese stuff, it depends upon the architecture of the specific unit. For all I know, the big Daytona lumps may have a lot more clearance. Be aware that there is an optimal size range, at both ends...C/S & wheel. 15t, minimum, is beneficial in terms of chain life, also adds some swingarm clearance up front...at the cost of chainguard & engine clearance. You may have to cut the chain guard.
No milling needed, on the Nice/Wave motors. The neutral switch is precariously close to the chain. And, if a chain ever broke, the results could be a Katrina-like disaster.
