The JIMS mini valve spring tester is a compact and precise tool that allows you to check the tension and free length of valve springs without completely disassembling the cylinder head. Essential for diagnosing compression losses and timing problems on Harley-Davidson.
Thanks to its compact design, this JIMS tester easily slips into the workshop or toolbox and allows you to quickly measure the condition of the valve springs. Worn or sagging springs can cause poor timing, power loss, and even serious engine damage.
Advantages of the JIMS mini tester:
- Quick check of valve spring tension
- Compact size for easy use
- Precise reading of free length and load
- Detects worn springs before breakage
- Professional JIMS manufacturing quality
An essential diagnostic tool to maintain the optimal performance of your Harley-Davidson engine and prevent costly breakdowns.
