For street hands down all my buddies running the piranhas and even the yx160s band through all the gears before I even his 3rd. Its an excellent cruising motor. But they do have there problems you gotta always kick them over at top dead to avoid cracking cases but that goes for both engines. Out of the two I like the lifan the most just because the larger gear ratios. If you wanna see one rip that I managed to fit/machine a xr/crf50 takegawa F6 super head on which is a honda style head on the lifan mid block stud pattern and accept the 32tooth cam gear sproket, it ate up every YX motor even ones with 50 more cc's and V2 heads. heres a video.

I'm trying to find out more info on this claim and where to get what I need to do this if I already had the Lifan 150cc engine and this is what I said and asked the person.
Is this the Lifan you're talking about 150cc Manual Electric Start Engine Motor PIT PRO TRAIL DIRT POSTIE BIKE THUMP US | eBay -

Furthermore what does the 32tooth mod bring it up to in max speed and does it turn the engine into a 160cc? My mechanic at Acworth Cycle & ATV has been telling me I could put 500 miles on the engine and do a mod to it, so would or is that the same thing here, or would that bring this up to a 190 instead of a 180 mod?
I do like that fact it's a hundred bucks less than a Piranha and I need Electric start for my street lights and am looking for MAX Speed and Speed modificatios to put on this Pagsta Choppa
Right now its got a pit engine Lifan 125cc and gets up to 50/55mph max, I never seen a Lifan 150cc Electric start until after I made a down payment on the Piranha 150cc
But after 500mile mod which engine can I get to max top speed basically, not that I'd ride at that but just in case? LoL
Anyone here care to step in on this? I seen a guy on YouTube with a Pagsta Choppa and a 200cc engine, but all the right sized 200cc's had no electric start or cdi for lights either even, so I'm thinking the best safest and fastest mod I can do is one of the 2 150's better sprockets, maybe better carb and a fuel injector and then last but not least the 500 mile engine, valve, piston mod.
Or would this PitsterPro 150cc allow me the fastest engine modifications for more speed

I see there's this 201cc bore kit 187-201cc Basic Big Bore Kit -
http://www.ebay.com/itm/301085647369 - TBW9145 - YX/GPX/Zongchen 150/155/160cc Engines but not sure if it'd work with this engine.
Would the Pitster Pro allow for the largest fastest modifications?

I've been longing to find a close to 200cc engine that would fit it properly and give me the speed I want instead of just putting it alongside the road keeping up traffic, and how would it hold up longevity wise on maybe a daily commute nearly or at least 4 days out of a week.
