Dynojet or JD

[TappedOut]

I have a 08 525s, airbox mod done to increase airflow and a HMF performance series slipon on the way. Which jet kit is better? JD or dynojet?

I like my JD kit.......but can not comment on the dynojet.

Add the HRC kit to your list. I just put one in my dads new bike and HOLY CRAP....it is wicked fast, sounds good, and runs nice....just got to finish the tune.

[ihackenberg1086]

is the HRC best then?

[sheriff525]

Personally I don't see a difference. If you know what your doing with the Carbs then get any of them. If you don't then go with the JD and it gives you a very good starting point. The HRC comes with no instructions. The JD has pilot jet, 2 needles, a few main jets and a big and small o-ring (for the oring mod). I like my JD kit. It is a good kit but the most expensive.

Since my bike and my dads is fairly close with mods I got him the HRC kit and tuned it after knowing where a good start was. Then I added the o ring mod.

ok JD it is then thanks

[sheriff525]

apparently I was way off with the HRC needle. It needed to be thinned out to as lean as I could get it. Now it runs like a monster. Great needle. Absolutely rips. Gives the JD some very tough competition.

I am considering getting a HRC needle for myself.

who sells the hrc kits? I can only find a kit for a trx450r. I would like to get one for my outlaw.

Hrc is Honda but both have FCR carbs and are interchangable

[sheriff525]

Exactly...both bikes have the Khienen(?) flatside 39 mm carb. so the Honda 450R needle is what you want. I believe it comes with a 162 main jet and a 50 leak jet. I don't have a leak jet in mine and it runs great with my HMF comp series pipe. and for a few cents you can get your own o-ring from Home depot and do the o ring mod.

[sheriff525]

I just noticed that you have a 500...that is a different carb. your carb is a mikuni i believe. so it wont work.

[katch26]

d'oh true story. You need to ditch that mikuni and work in a different carb if you really want to see some performance gains from the 500 motor.
