I spent a bit of time checking a spare R1 clutch yesterday and while I was in the mood I took enough measurements to make myself a clutch Holding tool. I was actually thinking that my R1 clutch is pretty light to operate and seems to have no trouble handling 140+ hp where as an LC clutch, which is not much smaller, struggles with a reasonably tuned LC. I then started measuring some clutch holding tools I've made over the years and realised the rust mild steel one(second from left) is for an R1. The ones either side are LC/YPVS. The small one is RD200. The green one is my first, made from 5mm/12mm flat bar, long before I'd even dreamed of laser profiling and CAD.  |

R1 springs into an LC basket?? If they are the same diameter but possibly just longer it may improve the slip issue, 9 times out of 10 better uprated springs is the cure.

I need a tool like your green one for my dry clutch.  I also think the same about the R6 clutch, buttery smooth and light. A lot of our problems is to do with the lack of plates in our clutches, also the actuator is different if i look at pictures on the internet. The 8 friction plate clutch i made is also nice to use with standard springs on a tuned 350 engine. |

The R1 uses a diaphragm spring. Basically a dished metal disc. I'd take a photo to show you but I've cleaned the clutch up, oiled it and packed it away. |

Postage would cost a fortune though, it must weigh about 3/4kg. I don't know what I was thinking when I made it. 3mm would have been quite adequate. I worked in a fabrication shop back then (1985). I must have thought I could use it as anchor as well 😃 |

I was promised a genuine Yamaha tool but still haven't done anything about it to collect it. |

I think I remember them being sold at race meetings by the tyre and bits man, Ken Inman. That's probably where the insperation for mine came from. But having no money and only having easy access to steel mine ended up weighing a few kilos. At least it cost me nothing. ken was an absolute genius at changing tyres. he made it look so easy and did it faster than anyone I've ever seen and with only tyre levers. |

One Friday my foreman gave me a wheel with a tyre to change. The tyre levers was two six foot crowbars. I tried in vain to change the truck tyre but it wasn't happening. Then my boss made it look so easy.
You can guess who bought the beer that evening

Then my boss made it look so easy. You can guess who bought the beer that evening Tyre changing is a skill that even after 40 years I've never mastered. I have two new Avon Roadriders in the garage that need fitting. When it was warm and sunny last week i thought about getting stuck in but it never happened. The theory was that the rubber being warm would be more supple and easier to fit. If youv'e not got enough skill you have to substitute muscle and big tyre levers so that's me. A mate of mine back in the day was proud of his tyre changing skills. he would be at mine regularly and for a cuppa and some biscuits he would happily show off how easy he could do a tyre swop. I was happy to sit and watch him and agree he had the knack  Was a good deal as far as I was concerned. I have four bits of wood screwed together that I put the wheels on. You can just see a corner of it in the top of the photo to the left of the wheels. Keeping the wheel off the ground is one of the things you need to do to make it easier. |

I have a cast aluminium clutch holding tool given to me years ago by an old workmate who raced a tz250 kart, when he gave up racing & sold everything he found it in his workshop & gave it to me.
Can't do pictures on here but sounds like the type mentioned, brilliant bit of kit I will never part with.

It took me hours to fit the last tyres I did a couple of years ago, had a right sweat on. I'm not sure but the beads seemed a lot stiffer and tighter than they used to be. I leave it to the pros now, it's worth a few quid and there's no risk of damaging a freshly painted or polished rim.

I leave it to the pros now, it's worth a few quid and there's no risk of damaging a freshly painted or polished rim. The beads probably feel a lot stiffer and tighter than they used to be because we're all stiffer and weaker than we used to be  It's alright leaving things to the pros but a lot of these things are often a big hassle. I had a rear puncture on the VFR800 but the tyre was about ready to go anyway. I rang a couple of places on the Monday and one said he could order the tyre for Tuesday but not fit it until the Thursday. Another said I could drop the wheel off on the Monday but they couldn't give me a time to collect. I told them to keep it and I would collect on the Tuesday. That was two round trips of 20 miles each and a big chunk of two days gone. I paid through the nose for the tyre and the privilege of getting someone to do it for me. My neighbour bought the tyre changing kit and balancing stuff because he was always swapping and changing tyres with his road bike and road/track Fireblade. With the right gear he said it was simple enough. I really should look into knocking something up from scrap metal |

I've found the bigger tyres on a modern bike are easier than putting the Roadriders onto LC wheels, worrying about nipping the tube doesn't help.
I'm sure having decent tools would have made things easier, I was using a pair of old tyre levers that didn't seem much better than a couple of pieces of 1" flat bar.

I've got some decent tyre levers now. I'm sure If I put something together that was heavy and strong and would hold the wheel clear of the ground and solid then tyre fitting would be so much easier. A lot of the energy expended goes into wrestling the tyre and the wheel around on the ground. Even my four sided wooden support makes a big difference. Something bolted down and made of steel would be another step up. |
