Just put on a LRD exhaust to get Absolutley No gain in performance

[beastsr20]

Hey guys,

Just purchased a LRD exhaust as recommended by everyone to gain No performance. I already had no airbox lid. The std exhaust had abit more bottem end and no difference in performance top end.

I thought it might of been me but I raced my mates stock blaster with his only mod being no airbox lid to find him pulling away from me in 5th and 6th gear

I installed the pipe, fitted a 310 jet and moved the clip on the needle to the 4th position from the top which is exactly what the tech support guy from LRD told me to do,

Does anybody have any idea why this exhaust doesnt perform, let me know, because I have only ever heard good things about LRD, so Im thinking there is something wrong.

Thanks

I would go down on the main to about 300 and put the clip back in the middle and try that.Check your plug after you do this.I:I

u shuld order them from ova here and ship em there like order from www.rockymountainatv.com and jus get em shipped

if your not satified with your ldr system, you could always sell it!

well, if jets are that expensive for you (and even if they weren't) you should always do a comprehensive plug test before rejetting so that you have a better idea of what you need to do.

 

[beastsr20]

Yeah I have done a plug test. re jetted a few times, so far, it runs best on the 300 jet with the needle in the second slot. Pretty dissappointed with this pipe. I can manage to now pull away from my mates stock 06 blaster(no Airbox lid) by 1 bike length with mine(no airbox lid, full lrd system),

 

[mr_3_0_5]

is your bike stock??

 

[beastsr20]

Yeah pretty much the only mods are no airbox lid and full lrd system.

 

[hickskateboarder]

clean your air filter, or just buy a new high flow one, and check your compression. if it's due for a rebuild performance mods are gonna seem like they do nothing.

hick's right.
also, i haven't seen the dyno chart for an lrd so it's hard to say, but it's more than possible that the pipe's characteristics are too strong for the stock port job.
most pipe builders aren't really out to properly engineer real good pipes. they just wanna design somehting and make some money.
this means that the cone lengths and sizes are just pretty much arbitrary parameters. having the pipe dynoed and the jug/head ported/redesigned to fit it perfectly is the best way to maximize the potential of your pipe and your engine.
for instance, i just bought the new shearer pipe from kennedy_power, who did my port and head job for me, and i sent him back my jug and head so that he could match the port/mill to fit the shearer perfectly.

 

[beastsr20]

I compression tested it before I put the pipe on, it had 145psi. The airfilter is clean and oiled lightly. I have taken the airfilter off for a run to see any difference and there was none I still think it has something to do with jetting, but dunno why it would need less then a 300jet but hey

 

[hickskateboarder]

did you check the plug?

 

[beastsr20]

Yeah, still running abit rich with the 300 jet, gonna change it to a 290/280 and recheck

 

[rm25x]

a pipe alone is not going to give you 20hp...

 

[beastsr20]

Sorry, it is a full system not just pipe

 

[xmous3yx]

im LRD full pipe= +12WHP. making it 24. cuz the blaster only gets 12ponies to the ground.

PEAK HP: 24 @ 7200 RPM. so i just ordered my LRD System. i ordered a UNi filter and jets with it. try a new filter.
