Nice looking engines ,but i think kyosho has gone backwards this time .these engines are made by toki japan and to be honest all engines made by toki donít last long .Team infinity engines are made by toki japan and they lose more than 50% of their compression after 2 or 3 litres of fuel.

I hope kyosho has made the right decision .

The infinity engines are budget engines and definately not the same quality as teh CRF's
When you have a OE manufacturer making products for different companies you will see they manufacture to price of product.So cheap engines will be made cheap.Its also the nature of business in the East, if you are prepared to pay for quality they will make it for you.

Reply from the other thread :

I think that this person does not understand CRF's technology.
Yes this engine is manufactured by Toki but a lot of the technology is very new and very advanced. The engine was designed by CRF Switzerland.
Toki is company with a vast experience in design, manufacturing and quality control. I can tell you that it's not just any manufacturer that would be able to manufacture the CRF engines in numbers and still meet the CRF technology specific requirements and a Japanese company such as Toki has proven it's ability to do this.

The fact that it is CRF puts the level of quality at an extreme level and nothing get's that label unless it passes strict QC.

It's not mandatory to use the CRF clutch with the CRF engines, that is if you know what you are doing and you can adapt/adjust the original clutch to work with a high power engine like the CRF.

However there are two main advantages when using the CRF clutch:
1. It ensures that you have a clutch that can work properly with the CRF engine (some original stuff it's basically impossible to get to work properly).
2. It is high quality stuff so it will work better and last longer than certain original kit parts.

Yes 0.50mm clerance (between shoe and bell) is the perfect cleareance, it's really important to have exactly this. Use more or less and you could run into problems. For the play in the bell, we basically use almost no play at all.
