LRD Pro series exhaust...jetting question

[400ex4ever]

I have the HRC kit installed, K&N Filter and am located right at sea level.

Just curious what others are using for a main jet with the same setup?

The instructions said it would be about a 190/195. I installed it and it seemed to run really good with the HRC 185 jet. Didn't get a chance to really get on it to see how the top end is after the exhaust install. Let me know. Thanks

My brother has the same set up as you and he is running a 195 main.

I got it jetted and all I can say is WOW...I am running the 195. I tried it with the HRC lid at first and it started to cut out on top. Removed the lid and it rips. I will be down at the Oregon dunes next week. I will let everyone know how it runs. Here is a couple of pics.

Head pipe measurements:
Stock - 1 1/2
LRD - 1 5/8

The numbers don't do it any justice. The thing is huge.

I'm running a 185 main. Did anyone go up a size or 2 on the pilot. I dont have the hrc kit i just have a k&n and no lid with the full lrd exhaust system.

Thats awsome you like it. I love the LRD pipe with the HRC kit installed, it really wakes the 450r up! When I get my 450r im going to put a HRC kit in it and a Yoshi full system on it but if I don't like the Yoshi then im getting the LRD. Buy the way what gearing are you running????

I love the pipe so far. Haven't really had a chance to open it up all the way. I will be heading for the dunes in Oregon next week. This should be a good testing platform.

The sound of the pipe is a deep rumble but not load enough to get the sound police excited. It starts to get a little load in the upper RPM's but not annoying. Sounds real good.

I am running a 13th front but will be bringing my 14th with my on the trip. From the short test ride I could do on my street, it seems to me that it revs even faster.

The newest ATV Action magazine has a write up about LRD.
