## Questions & Answers

A: Our product is 150CC, if your cylinder head is 125CC, you need to replace it with 150CC

**Q: Would this fit a tgb 304 125cc 2010**
A: The cylinder diameter of this product is 57.4MM, which is suitable for GY6 engine but not for Lifan engine. You need to compare with the old product. If the size is the same, it can be applied.

    150cc not 125cc, works perfect though
  

*by J***E on Reviewed in the United Kingdom on 24 July 2021*

So some of you may be confused. Here it is.I ordered this because my 125 scooter decided to pop a valve and blow a hole in the top of my piston, smash the bearing up on the camshaft and rip the rocker arms to bits on the way home from work, leaving me stranded on the side of the road for 3 & 1/2 hours awaiting recovery. In a desperate rush to get it rebuilt I ordered the only next day available piston and barrel, and head. Not 100% sure if this was for a 125 or a 150 I ordered it anyway. Turns out this is actually a 150cc barrel and piston.Which means: if your just looking for a 125 piston and barrel this isn’t what you want.If you want to go for the 150 like I did, well had to, you need to buy the head aswell with the valves (another £30) but then make sure you buy a valve cover also. As the head is non egr valve meaning the cover you have won’t fit.All in all, my bike runs mint now, not sure why people said you had to mill it as it slid straight together nicely. and don’t buy the goofit camshaft as they send the 50cc one which isn’t long enough, unless you bodge it like I had to untill one comes from eBay.

    Had to have valves lapped!!
  

*by J***Y on Reviewed in Canada on 4 June 2022*

Everything seems good except when i checked the valves to see if they were seating properly, i noticed they were not. Had to lapp both valves. No big deal. Easy job. Just letting people know this. Thats the reason for 4 stars instead of 5.
