It does take special tools, such as a Rowe flywheel truing stand to do the big end rod bearing. By the time you buy a rod kit and pay a reputable shop to do the assembly and truing, you can just about pay for a complete Hot Rods brand crankshaft assembly.

Do you have the tools to disassemble the crankshaft, pressin the new pin and true the crankshaft?

I guess if you are asking on here about it being easy, then you don't know just how difficult it is. Of all the tasks and special tools required to work on ANY part of your motorcycle, I can't imagine ANY other task that is MORE difficult than that. I suggest you have a professional rebuild it IF!!! a complete crankshaft is not availble for your (whatever year it si since you didn't bother to mention which of the 34 different year models it could be)

If you don't have tools, then I suggest you take it somewhere to have the work done. It CAN NOT be installed without not just tools, but special motorcycle specific, odd-ball tools. Even if you bought a complete crankshaft, special tools are needed.

Personally if the bearing feels worn I would just replace the whole crank to prevent any possible damage, I wouldn't replace the Con-Rod or the Big-End after what happened to my one of my Dad's bikes (about 35 years ago :shock:) where he replaced the Big-End and Con-Rod on a Ossa 350 trails bike and right in the middle of a rock climb (7000rpmish) because he didn't true the crank or anything the Con-Rod shattered with the vibration of the crank wobbling and the crank snapped.

It ended up costing more than the bike was worth

You do realize that there is suppose to be side play in the big end rod bearing, just no up and down play. If you have the tools to install new main bearings then you can do the crankshaft install. To rebuild a crankshaft does take special tools!

The Hot Rods brand crankshaft assemblies are very good quality as are the Wiseco crankshafts, or you could use OEM. My preference is normally Hot Rods since they are built right here in Iowa!

See if you can find some part numbers for a UK model, as the bikes are sometimes different. A crank rebuild kit is usually around US $100. A complete crankshaft is usually US $175 - US $275 or more. I am not sure if you are referring to a rebuild kit or a complete crankshaft.
