Thank you. I'm all about the diy work except when it comes to the motor. I'm familiar in general but don't really want to **** around. I did find another builder that's local that honestly I feel the most comfortable thusfar. He said proper head work together with exhaust,intake and tune and I should be pushing very good power. He's working up some numbers.

So, you are sticking with 107", the 574 cams and exhaust? So the tech is charging 4K for TMan's headwork, supply and install a larger throttle body, with injectors, labor and dyno tune? Not sure you will see much benefit from the larger throttle body without an increase in displacement and a cam change.

not with the 543 cam, at least i don't think that is likely. maybe. what size and brand throttle body was he thinking of, did he say? i would definitely re think your cam choice. and what compression ratio is the target?

Whats wrong with the 543 cam? He was thinking hpi 55 or 58 throttle body. Currently compression is 10:5.

I agree Marco but there have been nearly 40 posts since Miketv84 first posted and there are critical details that may not be included in the build plan; at least they are not mentioned. Since then he has been advised that better cams, headwork and more compression should be part of his plan and it has also been pointed out that gains from a larger throttle body would likely marginal and therefore, not worth the additional cost. He has also been advised that he should consider working a build plan with Scott and trailering the bike the 4 hour travel time to Scott to execute the plan. I don't know the builder he has chosen but pretty sure he does not have the depth that Scott does; I doubt that Scott would build around the 543 cam and that Scott would most likely include boring to 110". So, I decided not to ask any detail questions which might be seen as throwing rocks at his plan and let Miketv44 go the way he has chosen and see the results. I could be surprised but I am thinking he will be disappointed; we all have to learn how we learn.
