How do u think this would work guys?
2 Inch End Cap

 

[Schmitthead]

Basically its a HRC end cap. As long as you jet it should be allright. As for an alternative, I dont think so, maybe a upgrade from stock though.

It's actually a little bigger than the hrc endcap. Looks pretty cool and would probably be quieter than most aftermarket pipes. I may have to try it out, but I agree that the jetting is very important on this bike.

works great...I have one thats simular with a open air box and a 185 main jet and it runs great...and sounds way better then stock.

Did you get yours from the same guy or did you make it yourself?

 

[jmoney45]

Well I bought one. I'll post how it works when I get it. Anyone else have this insert?

mine is a HRC one. It says for competetion only on it, and it also says HRC. I got it from ebay, but its not homade...I think it may have been for a 400ex exhaust....maybe...but it works great.

could you just drill out the stock end cap?

The end cap that reads hrc is the one that come with the power up kit. It opens up the exhuast and makes it sound better than stock. I think it is funny that the ebay store asks "do you love the stainless stock exhuast?" I think it is HUGE and not too pretty. Better than flat black I guess. Come on UPS where is my HMF? I can't wait. I dont think just drilling a hole in the stock one would work becuase there is an entire baffle that goes down in the can. Maybe could cut it off though? HMMMMM.

there is no baffle with the HRC end cap, Its just the cap and thats it>...I have one and it runs like #ell!

I know the Hrc is just the cap with a spark arester, I was refering to the stock one having a baffle on it. The HRC end cap runs good with the stock pipe especially with the lid off and jet up like mad.

thats what I did, Sparks racing air filter, 185 main jet, needle on the 3rd clip, no air box lid, and 2.5 turns out on the air/fuel screw, and

DAMN, what a diffrence from stock, its like twice as fast. I cant wait to change the cam, thats next.

Well I got my insert, put it in, put the air box cover on a shelf in the garage, threw a 185 main in and took it for a spin. Sounds real nice but not too loud. Kinda reminds me of my mbrp exhaust on my 400ex. Pulls real good through the gears. Seems like the jetting is right on. Plug looks same as stock. Definitely worth the 30 bucks. I did this and modified all 3 suspensions settings on all shocks and it's like a new bike. Sits lower and rides like a highly modified quad and it's damn near stock. Very happy I sold the 400, even though it was a great bike.

did you readjust your air/fuel screw....stock setting is 1.5 out....turn it about 2.5 out...and it will run even better....thats giving it more air....and it will still run just as good as it was at stock setting....assuming you have a good high flow air filter...the Sparks works well.

I have the stock air filter and left the screw at stock setting. Where is the air screw located on the carb?

it is directly underneth the carb, spin the carb sideways some and you will see it sticking out of the bottom of the bowl on a long flange...its the only screw under there. turn in all the way in, it should be 1.5 turns. then from the all the way in position turn it out 2.5 turns and try it out....it should scream.

 

[mascman]

Would that work as well with the stock filter? How good or bad is the stock air filter compared to an aftermarket, and how much would jetting change between the two.

I have that insert and was going to leave the airbox alone, but i can't resist the thought of free hp just by removing the lid. How about just cutting the section out like the HRC? What would be a good jet for that and would you have to move the needle clip?

Thanks!
