What Valve Clearances Do I Use On My TBR7? With my 9 steps, valve clearance checks should be a regular, frequent maintenance item for the motorcycle. I continue to question the quality of the TaoTao TBR7, and checking the valve clearance is easy to do. Now I use this as a guide, more like a maximum. Per the TBR7 owners manual, I received very 6000km’s. I am talking about those of us who chose to do the final assembly of our motorcycles. Note: If your motorcycle arrives reassembled, such as with the CSC TT250, your valves are historically already adjusted. Moral of the story? Adjust your Chinese “250” dual-sport right out of the crate. Resulting in engine damage from ‘burnt’ valves. Valve clearances too small “too tight” can lead to poor heat transfer from the valves to the head. This mistake resulted in poor engine performance.

I had no gap I could measure from my rocker arms to the valve stem. Right out of the box! Too often, the motorcycle is shipped with the valve clearances too small. When Should You Adjust Your TBR7/Hawk 250’s Valves? These valve adjustment steps should apply to most Chinese “250” Dual-sport motorcycle engines (“Chonda’s”), based on the Honda CG-125 design(yes, over-bored to 229cc’s in the Chonda’s) These Chonda bikes are the RPS Hawk 250’s, CSC TT250’s, Bashan Brozz 250, and my motorcycle, the TaoTao TBR7.
