Скачать или смотреть Modified AJP PR4 Extreme and Honda CRF230f Comparison

Comparing my Honda CRF230f with my AJP Extreme after just getting the AJP back going.
Both modified:
The Honda: Bored to 67mm and stroked 4mm for 249cc. 12.5:1 Compression, Yoshimura exhaust, Big intake valve and porting done by Terry Miller, TM ST1.0 cam, Procom CDI.
The AJP: Stock 233cc capacity with about 11.5:1 compression. Mild port matching, Henner RXB230 cam with roller rockers, AJP PWK 30mm carby and intake Kit, Belparts Exhaust. The AJP has a bigger intake valve as stock than the Honda.

I think the Hodna has a bit more torque lower down, but both very similar output as far as I can tell. The difference might be the cam, Both lift front wheel in 2nd gear with very little pull on the bars. It sounds to me like the AJP needs some jetting refinement though.
