I bought my F1 partly restored and an finding out now that apart from some nice painting on tank and panels it is really partly restored. I've just spent a few hours separating the front callipers and master cylinder from the 2 front callipers, all the bolts are painted or just seized solid but something seems odd. I believe that the shoes for the 57V should be held in by two pins but they are actually held by a larger diameter bolt with an Allen key head. All of these were seized, all of the cylinders are seized. Are these possibly wrong for the bike. The callipers have been held fast in various vices and look pretty rough compared with how I want this bike to be.

Everything after the 83/84 bikes used the caliper with the single pad pin

F1 calipers do have 2 pins, and 2 pistons, so you have the wrong ones on there, single central pin is presumably from the earlier LC2 - it might be that you have the wrong fork lowers if that's the case too, as the brakes have differing spacings for the fork fixings, as ever pictures provide the best evidence. |

Sorry, its been a long day lol Yes 2 pins with allen key heads. I was getting confused with the older calipers with the 2 thinner pins with the little hex heads and R clips We need a pic of your forks and calipers Steve |

My callipers have only one piston. Should an F1 have 2?

Yes.
As above sounds like you have the earlier forks and calipers.

So the question is. My parts book for an F1 57V shows a single piston and two pins and I have a single piston and single pin. Gunny's pics show 2 pistons and 2 pins. I'd love to know what I have and can I get some pins for it

My callipers have only one piston. Should an F1 have 2? Should be opposing piston so yes 2 Does your front muddy have a U shaped bracket in it that bolts to the fork legs like a standard muddy or has it got a plate across the top that bolts to the fork legs like a brace Steve |

Norbo does the pins I'm sure for both types

Do you have a fork leg to hand ? The mudguard mounting for F1 should be boltholes facing up 2 each side, earlier 31k boltholes facing each other on the side |

What's the callipers hole spacing between the 2 mounting bolts? The later one have a 83mm spacing.

Thanks guys, I believe that what I have is LC2 callipers. What is an LC2? I unpacked the callipers to get them coated but they are a disgusting mess. The forks are packed still, they look very good. I'll get the pins from Norbs. Need shoes too?

As far as I understand, an LC2 is the first two years of RD350 YPVS production for Europe, '83 and '84. Have a look under models, here: rd350lc.net/The N1/F1 came out in 1985 with quite a few changes. Are you sure the frame / engine you have are F1? If you are after originality, maybe post some more pictures on here of the other components, to be identified as F1 or not. |

F1 forks should also be black
31k prefix covers 4 models
83 was 1st lc2 and model code was 31k (250 was 29l)
84 was also lc2. Different paint and a few small changes
85 was F, full fairing, lots of changes including forks/brakes and was model 57v
85 also had the N, naked bike but other than paint was same as F1. Model code 1JF

I'll be unpacking the bits more tomorrow so I can have a look at the forks, etc. These callipers and Master cylinder aren't F1. If I put non-standard parts on then I may as well put good quality, what fits the F1, did I see Triumph? |

You can put Triumph callipers on, I have them on my F2 but you need to make sure your fork legs have the 83mm spacing for the calliper mounts.
