Kits For Open Racing
The following are a list of
"off the shelf" parts that can be easily fitted to the GX160/GX200
engine to improve performance. Although some of these
modification are not legal for MSA racing (or clubs which
adopt the Honda Regulations), if you just race for fun then
adding one or a combination of these parts will improve
performance. If you are unsure check out the
Honda Regs
here or discuss with your club scrutineer. |
