Is your First Gen. VR getting less than average gas mileage? Are your exhaust pipes sooty? Can you smell gas after your bike has been running for a while? Well, i have the fix for you. Reshim your main jet needles to lean out the air/fuel mixture. This will increase gas mileage,and clean up those exhaust pipes. Others have re-shimmed the main jet needles with extra s.s. Washers, but this just adds weight to the end of the carb. Slider, slowing down the slider action and making throttle response “sluggish”. By using a nylon shim that has been precision machined, there is no additional weight to the end of the slider. This kit comes with complete written instructions, and can be done in about an hour using basic hand tools. The cost is $15.00 with shipping included in the usa. Out of the country shipping is actual shipping cost only! I accept paypal and checks! thanks for viewing my ad! skydoc_17
