Want to do the standard carb mod for my newly acquired 2004. I am a complete newbie when it comes to working on the carb. Did some reading/searching and came up with the following part # for the 132.5 main jet: 288−14343−66 Went to Boats.net and Stadium Yamaha and it shows as unavailable. Anyone know of a place that stocks it and if so, is the part # still valid? Should I be looking for the part under a different bike like the TTR225? Also, how many washers/shims will I need for the needle (I am at sea level, 60-70 degree weather year round)? Thanks a bunch.
