What's up guys. I just wanted to get some opinions on pipes.

My bike is a flat track/TT bike and has an LRD 350 power valve motor, and I run the LRD big bore pipe. I like the pipe OK, but even after adjusting it, it does hit pretty hard and is a little "peaky" if you know what I mean.
I just had the motor completely rebuilt, and my builder has been suggesting that I go with a Paul Turner race pipe for a broader power curve. This guy is very good with R's and has built several motors for me, so I trust his judgement. I'm not trying to start a lengthy debate, but like I said, I would just like to hear some outside opinions on pipes for my bike.

Any info would be appreciated. Thanks!

Wouldn't you want more of a TT pipe than a mx pipe? I guess the idea of a smoother powerband is for better traction control. Is that correct? The PT eliminator would have more top end like a tt pipe, also the sparks TT, and esr TRX5 would be good TT pipes. Not sure if they would be smooth enough for what you are looking for. If you want to try the PT race pipe, you can usually find them used at a reasonable price.

You're exactly right. When the bike hits now, if the track is even a little slick, it blows the tires right off, and the 4 strokes ride right by...LOL. There's no problems on a big flat track, you just pin it and hang on. But, on the smaller, tighter, more technical TT tracks it gets aggrivating. We run an all around pipe due to we run everything from little bitty tracks to big 'ol car tracks.
I've personally never ran a Sparks TT pipe. I have ran a TRX-5 on another bike and liked it. I've never ran a Paul Turner on a Honda. I had one on an old LT500 I had and was pleased with it. My friend has a similar setup to mine with the 350PV and runs the PT pipe and it seems to work great for him.
Like I said, I'm just looking for some input on ya'lls experiences with different pipes.

the PT race pipe is an excellent midrange pipe. its a pipe that is commonly run in open woods and MX if thats what your looking for you'll be pleased.

 

[Michael88R]

Sounds like you need an mx pipe with smooth powerband for tight tracks and a TT pipe for the longer tracks and ovals.

If you end up wanting a PT pipe. I have a good Paul Turner Hi Rev expanshion chamber and an okay fat boy scilencer or an FMF scilencer if you wanted to mix them. If you want it i would sell them for about $120

Hey Brady,

The difference between the ESR TRX5 certermount and the Paul Turner "Race 2003" is that the Paul turner will pull harder off the bottom and out power the ESR pipe all the way until the top end, then it signs off and the ESR TRX5 just keeps pulling all the way to the rev limiter. With your porting now, the ESR is actually a little bit smoother and easier to launch off the line because it has a little bit wider powerband, but the paul turner is quicker exiting turns and will outrun in on short/medium tracks. The Paul Turner has more quick passing power, as it responds quicker exiting turns, where you make your passes mostly. For TT there is no comparison, the Paul Turner is WAAYYYY better for that, but for slicker, medium sized flattracks the ESR is the way to go. For big tracks, the LRD will rip tall gearing and motor past either pipe but CANNOT hook on slick tracks and is too brutal to work well on anything but a hard, blue grooved TT track, and even then, it will wear you out within 5-6 hard race laps. Trust me man, We have tried them all and I think for a one pipe fits all best fit its gotta be the PT race 2003. It is what I am using now.

.........Just my $.02

scotts right. if we thought something else was better we would be running it. :blink:
but there is one more part of the equation.... rider. the difference between your average rider and a pro is that they have the ability and strength to handle a hard hitting,high reving engine and fly on it. but on the other hand you put an average rider on it and they cant hit on $hit.
difference is that its just too hard to ride. more lowend power makes the bike easier to ride in ANY situation and also gives smooth easy to hook power so it does very well in slicks conditions.
which is like 50% of the time. B) and in reality on the bigger tracks it only gives up a little bit.
but again having that smooth powerband will make you alot more confident. the trx5 is a great pipe and there is only a small difference between the two. either one will be much better than the one you got. the lrd pipes are just hard to ride.

.......... just my $.02! now thats just funny!!!!!

If I was Brady Id run what Derek sugested in the first place. He sure makes my stuff fly. B)

Ever thought about dropping a tooth or so on your rear sprocket to decrease wheel spin at times?

 

[mxduner]

I got an 89 race pipe, and i use it in mx.I do like it in open stuff, probably more for riding, it pulls good thru a wide rpm spread and is pretty smooth too.

Derek, yep, a simple case of an engine with cylinder porting & pipe not matching up with the rider.

You guys that I've had the chance to port a cylinder for & are reading this thread, now you know why I asked you so many questions before the work was done.
If the engine build dont match your riding skills, its going to be a handfull to handle out on the track.
95% of the TT & flattrack riders I have built for, needed a midrange or bottom end engine, big bore engine that is, not a 265.

Aint much any sweeter than a big bore 250R grunting, comming out of a corner toting the front wheels in a power slide.
Only thing can top that, is a pro grunting one, front up & jump up on one rear wheel power sliding & ride it out, now boys thats riding.

Oh & fastrnrik,,, that spinning & slick track, no problem, short swingarm & narrow those rears up will fix that. You tuck them rear tires & it cant spin.
