endofitall9 Posted March 27, 2006 Report Posted March 27, 2006 was reading atv action lastnight and there was an article in there about the 400ex. Evryone has been posting alot about the 400ex lately so I didn't figure it would hurt to put in here what it said. I'm not totally sure but I think every thing they put on it was wiseco, they put on big bore cylinder, hot cams, pipe and airfilter..after all the did to it they said it would run side by side with the 450r and the yfz450 pretty interesting actually they said all the extra power actually made it a better quad overall and that this is how it should have come from factory.anybody have a 400 like this I used to have one, figured it would be knarly for that little bike to have all that power............

txblueshee Posted March 27, 2006 Report Posted March 27, 2006 More than likely it's a 465... which is about reliable as a quadzilla... The only way a 400ex will run with the new production bikes is with a heart transplant... Not like I would know anything about that .... Mike Quote
endofitall9 Posted March 27, 2006 Author Report Posted March 27, 2006 465 sounds about right...that R you have there is nice..I've been trying to get one for a 500R project....... Quote
endofitall9 Posted March 27, 2006 Author Report Posted March 27, 2006 upon further review......nice EX you got there! Quote
txblueshee Posted March 27, 2006 Report Posted March 27, 2006 upon further review......nice EX you got there! 493084[/snapback] Look a little closer .... That's no EX .... Mike Quote
FasterThanU90 Posted March 27, 2006 Report Posted March 27, 2006 EX`s made pretty decent power felt kinda like a normal 4poke was pain in the ass to wrench on ,the carbs were pretty simple but everything was crammed together couldnt really fit a wrench anywhere and the seats are hard and uncomfortable , honda never really made good seats .

wantinashee Posted March 27, 2006 Report Posted March 27, 2006 the 400ex can be built to run for as old of a design as the engine is. my dads 440 has an keihin fcr carb stage one hotcam full yoshimura exhuast and a home port job and was pullin 40 horse on the ground, not bad for what we used, switch to a hotter cam and a bigger carb and it will probly be easy to break the 45 mark. down at little sahara last year and it was killing the 450's and craptors pretty damn easy. for an outdated design they can still be pretty fast.

sredish Posted March 27, 2006 Report Posted March 27, 2006 a good modded, big-bore ex can run with a piped 450, not too hard there. however, start getting a little work done on the 450 and it's over. Quote
endofitall9 Posted March 27, 2006 Author Report Posted March 27, 2006 crf450 in that quad?.........if so whats that thing like does it rip? didnt pay any attention to the kick start Quote
locogato11283 Posted March 27, 2006 Report Posted March 27, 2006 i cant see building a 400ex motor. thats kinda like polishing a turd... Quote
hittintrees srh Posted March 28, 2006 Report Posted March 28, 2006 the first quad i ever bought was an 00 ex- did a little work to it-nothing big, but it had the comon bolt on's i have to say-i loved it. it always ran well, never broke down, never had any problems at all really. I see it as a good bike to gain experiance on. rock on 400ex Quote
