today im ordering an end cap and i dont know which to get. is MRHP a lot better than mod quad? just a little better? or practically the same thing? price isnt the factor here. thanx

 

Go mrhp, the hp will be the same, but you get more than just an end cap. just read some of the old posts.

i would order mrhp's piece just on principle, he seems to be the first and since then lots of copy-cats, i ordered mine about 3 months ago, exellent service and advice he also sent me the correct jet for my elevation. im a welder i work in a machine shop and could have had one made but im sure ther was lots of time in testing, and thats worth something. by the way great sound noticeble performance gain.[img]i/expressions/face-icon-small-cool.gif[/img]

 

I've got two of Mr. HPs end caps, as well as his porting on both of my quads. You should consider getting your intake ported, that with the end cap will make it come to life. As well as ask him all of his tips on setting up the stock carburetor.

 

After porting do you need to adjust the carb if you have already done so to compensate for the end cap? I hope to get mine done soon and was wondering. I haven't decided if I'm going to try porting it myself or to send it to Mr HP. Any idea how much a new stock intake is in case i try and ruin mine ?

 

whats the porting from mrhp cost? whats the time frame in getting it done?

 

i think it is 150$, he has it on his website with the rest of his goodies.

 

thanks big show found it just before i checked back here. how do you like your 450r? , my buddy has a 400ex and wants one bad its just no match for the 650. i bug him all the time if he knows what 650-400=? i think next summer 650-450 will = 0[img]i/expressions/face-icon-small-wink.gif[/img]

 

cain73,

Mr. HP charges $150 to do the port work, and a new stock intake is $150. If you are confident in what you can do to your intake then it could be worth the risk, but there is also the chance you wont get as much HP out of the cut. However doing it yourself is free, but if you do it yourself, and don't get a good result it will cost you about $300 total to get it done at that point.

Personally I don't even begin to know what to do in porting an intake, so I sent both of my intakes to Mr. HP for a little love from his machines.

 

caandian, i really like the 450R, with a light rider it seems to hold up with the best of them..it has a unique feel to it. unfortionly my wife doesnt like it so im right in the middle of trying to sell it.
