Put a 750 motor in a Prairie 650 or 700.

I just did and all you have to do is switch out heads and output shaft.

Are you using BF 750 heads?
I've always read the frame won't clear but always hoped they were wrong.

I have seen a 750 brute force motor in a prairie 700 it is possible and does fit. Complete motor Brute force heads and carbs I helped him install it. Maybe he will post some pics of it if he see this post.

I have prairie heads. The heads that Grider had big valves and ported.
The prairie heads gives you more carbs to choose from.
If you use brute heads. You have to work out the coolant hoses. They are different on brute heads.

No it didnt need to be assembled in the frame it slid right in just like the original motor. Its not bad at all. The coolant tubes are routed alittle different on the brute but nothing major. He had to redo the bottom of the prairie airbox to accept the brute carbs but that was the hardest part. You cant run the prairie carbs on the brute heads they dont line up right would need custom intake boots maybe.

There will be plenty of video of a brute 840 at st.Anthonys mid July. I don't think you can go wrong there but it will cost for the right setup with carbs tires etc. Can be done though. Really not much difference in a V and a brute except 100 lbs. A well set up brute can stay with or beat most pure sport bikes. Even with my Fundy 750 and the 840 is like a 750 with nos. Big Kev will have his brute there and mine for sure we will be competive I hope. I'm saying this knowing we have heavy bikes but believe it comes down to setup.
840 in a brute is fast if the owner has any setup abilities is what I'm saying.

I'm not worried about the carb setup,I can deal with that. I just didn't like the idea of modding the frame.
Thank you..
