Got My Hands Full....TRX250R VS LTR450

[superevil]

I hang out with a guy that owns and races a laeger chassis with a yzf426 motor in it. The motor is very fast,and super modified,but he said it blew up twice in two years. First time cost him 1200 bucks,second time almost 2000.
That right there is enough to make me hold on to a 2 stroke as long as i can.

all of those dynos are at the rear wheels done by private owners not companies trying to promote there products, i think your just unable to accept the fact taht you can make a 450 fast, im not saying taht 2 strokes are slow, im just saying that 4 strokes arent, and you only ever talk about "piped and cammed" 4 strokes, theres plenty more you can do to them that i hope you know

4 strokes dont have adjustable powerbands. enough said.
go back to ltr450hq.. traitor

You are talking to a professional engine builder. I highly doubt Denny is biased towards 4 strokes for any reason. These "4 stroke builders" you talk to charge thousands to build up a fast 450. You can build a "faster than any 450" banshee for under a grand. I bought chvycrusin's 310 pv for my r. Id be willing to race just about any 450 with this cylinder on my r and it was 1150. Put that in your pipe and smoke it.

Have you been able to put that baby on yet?? You'll have to let us know how it runs! That's my next step... 310ish PV

i guess you were right there whe n they ran those dyno runs right ? i never said it is impossible ofr a 450 four stroke to go fast i said its rare and it wont come cheaply and reliability will suffer .some peopel have different ideas of wha t"fast " is though belive me i have had tons of seat time on 450's of various states of tune i have raced on them with the m and against them im well aware of their potential ,i dont care dont belive me then ,seems no matter what ,yo u wont listen to anyone but the guys on the biased 450 sites so why bother .
different stroeks for different folks i guess

well thats what im saying, 2 strokes are good for some stuff, and 4 strokes for others, but those are all dynos of motors that will last for a whole season of racing, which is enough reliability for me, and only go for about 2500, which is actually about the same as i was going to spend on my R motor when i was gunna make it a big bore MXer

and fulltilt im not talking about a ltr vs a shee, shees are twin cylinders, im talking about a 250 vs a 450, and it is just simply not possible to make a R faster than a built 450 with only $1000, you said you got a 310 for 1125, then you need a carb, reeds, filter, and a pipe. With your set up id guess what 55hp, and maby around 30 lbs of torque, which is good numbers for an R, but just simply look at the numbers of the ATP motor that im getting, 40lbs of torque, 62 hp(by the way ATP builds Lawson's motors)

You keep on comparing a 250 2stroke to a 450 4stroke and saying that the 4stroke is faster, etc, etc. What I don't understand is, you primarily race MX, where being fast (in a drag race) and huge HP numbers don't mean shit. There is no reason why a capable rider can not be "fast" on an MX track with a 2stroke. In fact, there are many, many racers who prove that every time they go out on a track.

Your R had the best of everything, Laeger narrow frame, Laeger Pro Trax, CR500 link rear, etc., etc. I mean c'mon here... There is no reason why you shouldn't have been "fast" on an MX track. None at all. Maybe you're just not capable? You think switching to a heavy, huge HP 4stroke is going to win you races? No.

Good luck.
