Please put this Wild Card at the top of the thread to make easier the searches and avoid repost. So, works like this: You want find info about the M90 transmission using the search function, but if you write M90 as a keyword yo got a error, so you put instead M90* and you got your results.
helpful thread, found what i was looking for thanks

Really new to the ATV world myself, but IMHO, the rev limiter is there to protect your engine. You will not get any additional power by over reving it, only additional broken parts, ie valve springs, valves etc. Again, just my .02
is there any highly detailed staged upgrades for 700's around all the mentioned links are dead.
Got really excited seeing this info and then got bummed to see everything I was trying to look at was broken besides a 240 service manual when I have a 740. :(
Small Block Ford Conversion Manual

A rather extensive discussion on installing a small block Ford V8 into a 240 series can be found here:


Your experiences and ways of doing it better as well as questions are encouraged. Additional details on deviations from this engine, transmission and vehicle are also solicited.

The intent is, through contributions from forum members, to create an single source of information that I would have dearly loved to have found 3 years ago when I began this project.
