would like to know if i were to buy a brute 750 can i take a a rear end from a brute 650 solid axel can it work together??? anyone help on this. reason being want the big motor! and new bike but still want the handle of the 650?

 

[ncrider]

Buy the 650 and do a big bore kit.

 

[crazy650]

the problem with that it well never be as fast as a brute 750 motor? So im deff going to get a prairie 700 or a brute 750 and change the rear end some how even if it has to be custom made

That would be cool,keep us posted if you go through with it.

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.

That's great to hear..
Did it need to be assembled in the frame?

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.

Put a 730 kit in the 650 motor (698cc) 60 rwhp and it will whoop the 750's (45 rwhp) ass and keep the SRA. you can do it for probably under 1500 bucks if you do it all yourself.

yes what john said you woun't be disapointed

what is the deal with the 840 kit? i would like to see a youtube video with some one's different kits on there bike you know be nice to see the difference in power sound what makes more toque im all about toque Seeing im down hear to get throw the deep mud cause im going to have a 2inch lift with outlaws 30inch tire's. im looking to smoke the 800 can am's.

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.

 

[crazy650]

well im not looking to race at all im all about toque I well be in the mud and swamps thats about it. I like to trail ride to so thats why like the prairie sra. Any think i should stick with a p700 and just do a big bore kit?

My little 730 Prairie runs pretty good

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..
