There all about suspension and mx, there also geared very low so they wont do the greatest in drags, i think if the LTR has any motor work done, your gunna need bigger than a 310, correct me if im wrong, but most 310s put out what, 53 hp? thats pretty good, but they still lack torque, so thats where youll need the extra ccs, i know everyone will argue with my post as usual because im speaking against there beloved 2 strokes, but im being realistic here.

And catch me if you can, if the LTR has the sparky out and has a crbm, it should still beat a stocker raptor

HES BACK!!! so if it was 48 hp bone stock, your intake and pipe only added 3 horse? that sucks... id ask for a refund on that hunk! haha
they arnt meant to be fast? so slower is better..? make up your mind, i think those guys at ltr450hq have you brainwashed already... yea they are the heaviest 450, by quite a bit, but whats that have to do with suspension and its purpose as an mx quad?? you arnt making much sense man..wouldnt lighter be better for mx...?
no one would argue your posts if you tried to at least make some sense for once...
and have you raced a stock raptor with your stock 450 to know this? or does it just beat a raptor cause you own it? same old shit.. i bet your stock 250 would have beat a stock raptor too, (6 months ago when your 250r was the best)

all i can say is post up the dynojet dyno of the ltr450r after al l this crazy work and i would like t o see it make a true 60 horse at the rear wheels your gonna need alky good pipe porting hig hcomp piston cherry bomb LD cam and likely a boost off a bottle as well ,just a play port and head cut on stock bore and stroke banshee will make true 60 horse on pump gas with 35+ pounds of torque at the rear wheels ,a 310r can make over 50 horse fairly inexpensivley once its opened up .getting a good 50 horse on the 450's is the easy part but pulling past that toward 60 well it gets very tough and very expensive not to mnetion reliability starst to fizzle out down the shitter

You can get a dyno to read whatever you want. Also, 2 stroke hp and 4 stroke hp are completely different; they shouldn't even be compared. If I remember right, it was a feat for the dirt bike 450s to get 62hp out of their engines. That makes it hard to believe you would be pushing 60 with a counterbalanced engine in a quad frame.

Why would an mx ready quad not be designed to be fast? sounds pretty realistic

You could probably beat an R450 with a drag ported 250 cylinder, though it would be worthless for anything else.

I would race an mx 310 with proper set-up against a 450 on a track and I know it can be set up to win in a drag.

Two strokes are very capable in drag racing; the disadvantage is, unlike the R450, they won't be good for anything else once set up.

Looks like flotek got his post in before this went through.

Well, I haven't got my R done yet but I can beat him on my Raptor. The 450 is cherry bombed with the exhaust packing removed. We dragged on pavement and gravel. First time we tried I got a shitty start and lost about 2 quad lengths and he didn't gain any more from there. Second time I beat him hands down. Then we raced on pavement, a line of the two of us and two 250F dirtbikes. Anyway, first attempt wound up in both of us just jumping into mad wheelies haha. Second attempt I walked on everyone else in the lineup. In my opinion, the LTR didn't live up to what I was expecting. I haven't modded that Raptor at all, just added weight with full under skids and a bumper....

Threw together the 250 the next day just to take it on a quick test run and god damn does that thing's powerband slam in 3rd gear...... haha

who wants to bet that fastR puppet is posting allthis on his ltr450 forum for a bunch of 16-17 year olds to pick apart and laugh at all of us and our 2 smokers, with of course, the usual numerous statements about how 2 stroke topends 'blow up" all the time coming from a bunch of them

thats actually not true at all, most people on LTR forums are duners that also have shees, or they race mx and came off of mx Rs like my old one, almost everyone respects the 2 stroke there, but we have all just moved on, and the 48hp comment is true with crbm, no lid/baffle, inother words $40 of mods, i think that you can still call that stock

[ky 2stroker]

now guys dont F-up this thread with bullshit and make it retarted like past incidents, otherwise it will be closed down and just a waste of time.

I think some of you guys that cant stand when people talk about 450s and how fast they are and everything, need to actually ride one and it should change your opinion of em. they are fast indeed, and have a different feel wioth the power delievery and all, but in most cases they rev just like 2 strokes. no hesitation, just very quick and to the point and they put the power to the ground.

[fastR of puppets]

ya i my LTR revs almost as fast as my R which was set up all for quick revs and had a cr ignition, like ky said, if you havent ridden both an R and a LTR then you cant be comparing them, 4 strokes have there ups and downs, but so do 2 strokes, some people like the funness of the 2 stroke, and some people like the usable power of a 4 stroke, its all personal oppinions, im not trying to convert anyone, im jsut giving my views, and some basic facts, because numbers cant lie


and heres a 60hp dyno run for you stock bore stock stroke



60,17whp 40,5 tq

Run was made with half C-12 and pump gas 94 octane

It's a low cost national engine. At this point the engine has over 16 hours without any problem.

Engine mods:

911 Head Porting
14:1 compression ratio
Hotcam
Dasa Pipe
Yosh PIM
No air Box filter kit with KNN

O.E.M Valve and Crankshaft


and by the way a fuel atv intake would probably add another 2 hp to taht because k&ns dont do shit on LTRs



and heres another for a pipe shootout



and finally this is the same motor build that i will be getting from atp which includes

14:1 piston
+1 Ti exhaust valves
head gasket
base gasket
port and polish
competition valve job
Performance intake cam
Tear down and assemble complete engine
Complete transmission service

and by the way that all comes to just $2304.57, which is really nothing when you think about it

and i would also be still using my power commander iii, dasa pipe, and fuel intake


so flotek do you still doubt me, i have to try and find it, but theres a dyno sheet of Byrds 450r up somewhere on the web, stock bore and stroke obviously, and making almost 70hp
