Finally I am starting to collect parts for my rebuilt . As a standard Jap spec model it came with 30mm carbs and 22D00 SAPC unit . Never gave me any problem but at the same time it only produced about 45HP .Un-restricting a SUZUKI RGV is not a difficult task all that is needed is 34mm Carbs and an un-restricted SAPC unit . More information upon SAPC units can be found at rgv250.co.uk .

34 mm carbs for higher output and torque than the 30mm standar jap spec ones .

22D30 SAPC UNIT
" This box only opens the pilot air valve between 500-2000 rpm, and is the most common un-restricted SAPC box available"
A new or well preserved un-restricted engine should be making around 52-55HP
Both of them costed me £60 which is rather cheap if you come to think that you gain about 10HP instantly .
