LC135 Y15ZR Y16ZR HPSP RACING TIMING CHAIN TENSIONER GUIDE JET UP 4.65MM 6MM-8MM 8MM-10MM

HPSP Racing Tensioner Guide (Jet Up) is a timing chain (cam chain) tensioner guide for Yamaha LC135, Y15ZR and Y16ZR engines with a jet up / block spacer setup. Raising the cylinder block lengthens the timing chain path, so a longer guide is needed. Choose the size that matches your spacer thickness.

• Made for jet up (block spacer) builds on Yamaha LC135, Y15ZR and Y16ZR
• Longer guide length to suit raised block height
• 3 size options matched to spacer thickness
• HPSP racing part, sold by Speed Parts
