ive had bike carbs on my xflow for over 10,000 miles and theyre superb BUT bogg brothers arent, got the kit from them and had shit loads of problems, mainly its attitude on the phone from steve, couldnt give 2 shits once you've paid. and as for the glue?? exact same thing on mine, i rang for spare parts and was told they didnt know what bike they were off and if i wanted them to fix them i had to send them back, and i quote "you'll have to wait for a fucked set to come in as im not breaking a good set to fix yours" WTF!! id paid £550.00 all in and wont be doing that again with them. on a plus note though, the dad runs the rolling road and he's always been bang on and the welding on the ali manifold is fantastic, but customer service and after sales service is just shocking. id buy a manifold from them but source every other part myself, carbs, £70, throttle cable is a mountain bike brake cable from halfords for £1.99! they charged me £15. filter cocks £20, 12v bike fuel pump from the same bike as the carbs, £20, and im rolling on 45mpg with 120bhp, thank you, lol.
