Because Ivan,

Each time you press a bearing In and out of the case, It will slowly warp out of spec.

Thats why.

I thought you were a bike mechanic??

Do it properly and you dont have to press them in or out, thats what ovens are for

[Sketchy_Racer]

Oh,

I tried the Oven approach to the mains on my KE125, but had nill effect....

So i ended up pressing them.

Do you still have to use some persuasion to get them out??

normally I have just heated the cases, then given then a bang on something and they pop out

[Sketchy_Racer]

What happens when the engine heats up and the cases expand?? wouldn't the bearings start to spin in the races if the fit was too lose??

[Ivan]

no i remember i used a heat gun and heated the cases aluminum expnads quicker than steel and they just pop out

the cases dont get that hot

[Shaun]

What makes you say that Shaun?

personal experience?

The TZs are know to handle better, and be just as quick as the honda when set up correctly.

The engineering side of them is Far superior to the Honda as well.

The worst part about the yamaha, Is the cost of spare parts. Like the Crank Cases on the honda cost 500US Vs 1200US for the Yamaha. But the yamaha one are supposed to last where the Honda ones start damaging bearing surfaces after around 3-4 rebuilds.

( All my info comes from people from the states who have raced both bikes )

Do you know where a good honda is for sale??

Yes Experience, I have raced both brands.

Show me any where in the world where a TZ 125 is as fast as the Honda RS125, and I will show you a team with a huge budget.

The Honda is the proven bench mark for 125's mate

Web sites can be a dangerous place to get your info from.

No I do not Sorry

[Sketchy_Racer]

Thanks for the advice.

After chatting to people face to face, they all agree on what you have said.

cheers for the heads up
