02-20-2018, 02:48 PMHello Guys! I own a German Sinnis Apache 125, a SFM Sachs ZZ 125... is there a bigger bigborekit than the 150? im not afraid to split the case... i just want to go "crazy" since the sinnis has a bad reputation in Germany due to low power and poor reliability, and i want to prove them that they are wrong! Is there a way to get more than 15hp out of it? It doenst needs to be legal.
My Sinnis already has well over 50k km on it too, i use it for touring and i love it.IMG_20171208_175559_438.jpg

04-29-2018, 08:51 AMI know you wanted bigger than 150, but 150 is good on a bike this size for torque and rideability

I have modified a SFM125 Roadster with the same K157FMI engineer, there is also a link to the place to buy the kit - this s a 124cc labelled big fin for cooling. I have done 14,000KM on it and it is good. Key points..
You will need to find an agent to ship the item below but it is worth it!!1
http://world.taobao.com/item/1369688...?fromSite=main
1. You can do it in a day - this is a straight swap
2. Torque wrench required !!!
3. Upjet to 115 worked for me
4. Do not take all of the camshaft cover bolts off - 2 are for the rockers!
5. If you drop the cam chain into the crankcase-this is easily retrieved with a tent peg - it is the camshaft c-ring you should watch
6.Exhaust bolts - change for M8 and use two nuts on each for ease
7.Don’t forget to take the emissions connector off the barrel - it is two M6 bolts
8.The camshaft tensioner should be removed -easy to reset the spring. -on the barrel
9. Get 4 new Head bolts from CMPO (UK) as a precaution
10. Get 4 new M8 nuts - 2 domed and two serrated flange for the head
11. Remember to reconnect the Emissions pipe to your carb (comes from the vacuum unit near the front)
12. Go for a 1:3 gearing ratio - eg 15 teeth front 45 back. This will rev out lower but given more torque and will hit 110KMH
I also own a SFMZZ125 , I haven’t modified it yet, but is slightly easier due to clearance.

That seller seems the 1st made these kit available in chinese 'net. https://item.taobao.com/item.htm?id=531995601742 is ~40% off the above...
Better rings https://item.taobao.com/item.htm?id=546681206119 ie. The good old [1.2/1.2/2.5] CG150 (those 1.0/ 0.8 is for newer genration piston)Last edited by humanbeing; 04-30-2018 at 12:57 PM.

Is this the correct kit? Also i know LT230S camshaft will fit the pulse adrenaline so i will upgrade that, Would this give me a displacement of 190cc? BLACK GS125 XIAO correct?
