In all honesty, and within limits, the length of the spring won't matter. What will matter is its strength... A couple of mm either way in length won't matter, but a thicker or thinner wire will (it's not the length, it's the girth!!!). It may even be the case that the slightly longer ones are 'upgraded' ones, or just 3rd party and not quite in spec. If you're really worried or suspicious, go to your local Authorised Yamaha Dealer and get them to order you a set for your specific bike. It may cost a few quid more, but you're guaranteed they'll get the right ones..! And just to answer your questions directly..: 1/ My Haynes manual suggest 36.4mm. The problem with Haynes is that the bikes they take apart for the manuals aren't new (one assumes that would cost a lot to disassemble a brand new bike), so measurements that small may be... Slightly off... 2/ My manual I downloaded suggests 34.9mm. WHAT manual? I trust nothing off the interwebz completely! 3/ The ones I got from Yambits are 34.7mm. Yambits are usually pretty good and I use them a lot, but I did get some petrol tap seals from them that were VERY much oversized (thickness) and were useless (so fat they locked up my tap). 4/ Ones for sale on Autodoc suggest 36mm. Never heard of Autodoc...

That's handy, cheers

Does it have an immobiliser?

Aaah, see now, that makes much more sense! lol

When you say 'rotor' what are you meaning? Brake disk? Something else?

Sent... Get yourself up to the New Members Area and tell us about yourself, and more about this PowerTronic doobery!

Sure you can (done). Go make a post in the welcome area and tell us about yourself & bikes & friends bikes... lol Not a clue about the code clearance thing. I've never actually LOOKED at the file!!!

This might be some use... https://www.ebay.co.uk/itm/185869019073

For the XSR 125?

Not a clue... Possibly Prime? A kinda choke thing?

Ok, so, their website gives no clues at all... The word 'standard layout' would be leading me to think you have a hop-over kit... Motorcycle_brake_line_setups.pdf (shopify.com) Like on that link. Which would mean the short one is for the hop-over. You're going to have to bite the bullet and phone them up and ask I think. But, to be honest, if you DO have the hop-over version, you've got the wrong one, you really need the '2 line race front' version to get the most out of those impressive blue spot callipers!

It depends on which set you got... If you got the '2 line race set', the rear line should be the short one. If you got the 'up & over' set, the rear line should be the middle one. So, which set did you get?

#1 #2 #3 #4 After some sleep, those 4 took me 30seconds on Google to find. You've specified that it's a 1984 bike, but I can't find any reference on them that isn't 1980... If there's a difference, you're out of luck. You'll probably have to either patch the one you have, make one yourself or have one made for you.

Ok, there you go, sent it in a PM...

Not a problem. I've just got back from 'down south', 6hrs riding my V-Strom with our lass and full luggage, my ass is killing me and I'm a little frazzled. It may take me a couple of days to figure out what I did with it... If I haven't passed it over by the weekend, make another post here to remind me!

Welcome in there, tell us about yourself...

Aaah, that rings a bell from long ago! Question: Can you see the head bolt shafts through the veins of the barrel (when in) or are they enclosed? It looks like a case of: If they look ok, it's fine, if they look screwed, replace... The old adage is: If it ain't broke, don't fix it (but when I have ever listened to myself...)!

Someone else will give better advice, but to me it looks like a sacrificial part. The question is probably: Does it still look in good condition or does it look 'used'..? It may just be so that the other parts don't 'weld' themselves to the barrel or crack under the expansion & contraction of an air cooled engine.

Congratulations..? lol

From what I remember of bikes from this era, turning the light won't help, it will still be in the way... As a different direction, what about the clock unit? What's holding that on? Would it be easier to displace the whole clock unit?
