To be honest I did not hook the new line up yet I just unbolted the top blocks to get enough hose so I could use the bike
I just looked at the clutch line and you could order the same line as the brake line and you will have PLENTY of hose, that is what I'm going to do .
Now If you want to get real annal I guess you could send in those lines and see IF they have a block to put on there to match OEM ,(so it would be REAL secure) I would send pictures first if that is what YOU want to do, but It looks to me that you unscrew the hard line from the block and then attach the new line to the hard line with out blocks, because it is a female fitting on that end that looks like it will fit.
I bought the LSL handlebar kit used it did not come with Instructions , but Spiegler said LSL calls for this part #?
I'm sure others on this site have done the LSL conversion ask them , on the other forum, cog-online that guy started a thread about LSL's ask him about the blocks.
