any fw05 shafters here be able to help me? limited information about fw05 is available so i have decided to ask here. i currently own a fw05-s and i have problems when i upgraded it to 2-speed transmission. the second spur gear seems to rub against the 2 speed clutch bell when i assemble it.

does anyone knows if the option part (LIGHT WEIGHT CLUCHBELL FOR FW-05
VZW043) or (LIGHTWEIGHT CLUTCH BELL (RRR)
VZW213) will be able to solve the problem? i have checked the website on the parts acceptable list and it shows thats it an option part(suitable). i am using the stock engine GS15R and normal 2 speed clutch bell (VS058) that comes with the 2-speed transmission for GS15R.

i just want to be sure before i commit into buying. sorry if this have been asked before. any help will be appreciated .
tks a lot guys.
