Thats why I suggested both OEM and Boyesen. A big bore kit would do alot more for that bike then putting in after market reeds on an OEM reed cage. Oem reed cages and aftermarket reeds are't gonna make a noticible difference. You might notice a difference with an aftermarket reed cage and reeds. But he doesn't have that option with that bike.Any real reason why you want to spend money on "wallet bait" gimmicks on a 27 year old bike ?
+1Boyesen power reeds are quite an improvement over the stock reeds in the area of low end throttle control. They bolt onto the stock reed cage, and are very affordable @ about $30. Don't think twice about installing them, it's not a "gimmick". They just plain work better than the OEM reeds.
