first i would just like to say that i am new to the site and i already think
its great. now for my question: i am about to order the hmf eco exhaust
and a k&n air filter. i was wonderin what is the best jet kit to buy and what size i should run. on the hmf site there is an option to get kit and filter w/pipe. should i just do this or you recommend other? i appreciate any info

Just get a OEM 135 jet from your dealer. It works alot better than the dj kit and order your filter seperate. The jet is only like $8.00

some people on here say that you should just figure out what size jet to use and buy that jet from the factory...they say the jet kit comes with alot of stuff you dont need and from what I hear the DYNOJETS dont flow as good as those from the factory. ask around and someone will know about what size jet you should use....plus you will save like $30

eustis you say get oem jet yet it says u have dyno jet. do you not like the dyno jet, or oem is just as good and cheaper. i dont want something that is not as good just cause cheaper

If you aren't going to snorkel it, the dyno jet would work okay, but why spend the money?? We bought the Dyno jet after the new ehaust and a snorkel, but could never get it operate right. Went with a factory 135, I
think Carl got both for $5. Now we have 2 Dyno jet kits in the garage that aren't being used....wish we would have saved that $60.

sounds good ill go with the 135 and you say i can get it from my honda dealer

 

[Railroader]

Should have them in stock..give them a call. Carl actually picked ours
up at an ATV repair shop!

The 450s have adjustable needles stock as well, Which will come in the Jet kit. The new needle will have a slightly different taper. Plus a new carb spring. These are things you can live without though.

When I got my jet kit it didnt come with another spring. But I took that kit out and just did the OEM and it make more of a difference than the kit.

The 135 is the way to go. I noticed a differance pretty much right away.

 

[red450rider]

thanks for the info ill go w/the 135

 

[eustismudder]

Be careful with the screws on the bowl cause they are very soft and will round out.

as far as the spring goes just cut about a inch and a half to 2 inches off of it like eutis says and that should take the place of that.
