I purchased this UNI - (PT-3429) Compact Version 2-Stage Foam Clamp On Air-Filter to use on my Keihin - PE24 Carburetor that I use on my Takegawa Racing - 106cc Superhead+R Big Bore Kit (14HP+) on a 2005 Honda - CRF-70F Pit Bike. I needed a UNI Air-Filter that was far more compact than the standard version UNI version # UP4182AST that sticks out & rubs my leg & gets sticky foam filter oil all over my leg while riding. This compact version UNI Air-Filter is by far much smaller & works better than the standard version but was still going to get my leg oily while riding being it was still too large in length. So I made sure I also purchased a Outerwears- Pre-Filter (part # 20-2892-010) that matches this compact UNI Air-Filter perfectly & keeps the sticky foam filter oil from ruining my pants all the time. This was the best sett-up I can still find to this day for dusty off-road riding but I really wish that UNI offered a small 2" height x 3" diameter & 1.75" Inner Diameter 2-stage foam button/pancake style air-filter to be able to rid the problem I have with any UNI Air-Filter being too large & they all rub my leg while riding my highly modified 2005 Honda - CRF-70F Pit Bike. Its better than the others I have used so far but still not nearly small anuff. I highly recommend this UNI - Compact version 1.75" Inner Diameter 2-stage Foam Air-Filter to others that use a Keihin - PE24 Carburetor on there high end Japanese made Takegawa Racing Big-Bore Kit like I use.
