Hey, guys. Sorry if this isn't the right place to post this. I just need some help and advice with a few things. I have to do a total rebuilt on my Typhoon 125 engine because the last mechanic I went f*cked up my engine. Now I need to buy everything new and I want to update it for a Malossi 172. My idea is to fit the Malossi kit with a 52mm Jasil crankshaft. Anyone have any experience with this crankshafts from Jasil? Only thing i know is that it is a Portuguese company and I'm especially worried about it's quality/durability... what do you guys have to say about this? And one more thing ... I'm doing this to be a everyday bike and as I said my intention is to fit the Malossi 172. And also a gear up kit and a 25mm carb. Can I run it with the Typhoon 125 original exhaust? Thanks in advance and sorry if I write something wrong, this is not my language.
