That's what i was thinking bro. That's why I wanna know what a 1430 or 1429 cc bore with a good head will put down. Even tho there's no stroke like the 1441 I'm just curious what they put downHe would not have pulled it with ease. 14r is 205-210 whp with a pipe n tune. If you are bound and determined to build an all motor bike to run with them, or out pull them, you can, but it's gonna cost ya. @greg3852 built a 1397 which made +/- 190 I think, so you can see that ain't gonna get you where you want to be, a 1441 will get you closer, but you'll still need to spray it. Weight is a huge factor as well, both yours and the bike's.
