Build a 416 or wait?

[Todd 54]

well, I'm looking to sink some money in my 2000 400ex. However, I don't want to spend a lot of $ if a new quad is comming out pretty soon. Has anyone heard of a 450ex or 650ex comming soon, or should I just give up like the rest of you have?

I'm kinda in the same boat. I'm really hurting for more power but don't wanna waste any more money than I have on the motor if I may do a motor swap in the next few years.

I'd rather get a aftermarket rear end (rpm swingarm, rpm axle, carrier) and then put my front shocks on my dads quad and go w/ a long travel front end and after that get the arens frame that can use either the crf or 400ex motor and by the time i'd have that I could pry get a good used crf motor for a decent price. Sept i'll be like 20 by the time I have all that working non-stop. At least i'll have one bad_arse machine.

From what I hear (via a very reliable source) the new Honda sport quad will not be out for at least another year and will be a seriously detuned 450 (no surprise there). I obviously don't have any hard facts (no one does) but this source has been right on many other ATV related stories in the past and I have no reason to doubt it now. I saw go ahead and build up your 400ex :)

[Castor-426ex]

My 440 was done right.. I dropped almost 3 grand into it so it is running great! Bullet Motor sports (http://www.bullet-motorsports.com) they did my engine work for me! he is one of the best in Texas!

We'll see what the ol' 463 will do - I'd say close to 50hp with the combo we are going to run. I'll stick it on a dyno and post the results this summer.

[QuadR8cer12]

Good luck with that man!! My 440 is so fast! That quad your building is going to RIP!!!I hope you dont have any engine problems:ermm: I have only had one problem and that is that I blew my head gasket the 8th day I had it...I had about 4 1/2 tanks of gas through it and I was finally starting to go more than just half throttle and somehow it got messed up in the break in so i had to get that fixed and I am still working on getting my CFR carb tunned in juuust right.... I am taking it to Bullet motor sports sometime this week...there is a big dead spot when you give it gas and the idle is turned up all the way so we are going to have to change the jets in it I think....Good luckwith your project! I wish I could ride it after you finish it!;)
