I would buy the HPR 730 kit with the 11.1 to 1 piston and the TM 45 carb and the end cap all from HP Research. You will not be disappointed. [img]i/expressions/face-icon-small-wink.gif[/img] You should be around the 60-62 hp range.

 

how many$$$$

 

Well, you are looking at approx $2300 for that particular setup. You will have reliability, low end torque and you will be very competitive on the drag strip.

 

nice now i must go now thx a lot dude a nice winter project 2300$ us 3000 3300 $ but if it's reliable it's worth the money

do you have the site of hpr i will cheak that by tomorow morning good heavening and thx

 

hpresearch.net! No problem. Any time! [img]i/expressions/face-icon-small-smile.gif[/img]

 

BUT your setup is cheaper than a 730


how mush for drag pipe carb the ported intake i can do it thx dude

 

For what you are doing and looking for I would go with an 11:1 piston, port work and a set of cams (along with new valve springs) and new clutch springs.

When we talk Stage I, Stage II and Stage III this really goes back to Ron Wood as they were the first to offer such kits for the DS. They are at rotax(dot)net. You can also get their parts from On Dunes.

I would recommend a Stage II kit for you. This is much less expensive than the 730 and will offer huge gains and as well very good reliability.

A Stage II bike should have no problems in most drag races.

For your riding I would NOT suggest a drag pipe. I'm guessing you are riding in areas that are near population or that may require spark arresotrs. I think a full pipe is what most of us should look at, if for nothing else we don't want to be a bunch of loud riders causing noise issues or everyone will hate us.

There are a number of builders you can look at for this set-up:

On-Dunes
The Bom
HP Research
Ron Wood
TVI
etc.

All are very reputable.

If after all this you still want power for the drags, add a nitrous system and you'll have no problems with your buddies.

 

Drag pipes are obnoxiously loud..... [img]i/expressions/face-icon-small-disgusted.gif[/img]

 

thx for the reply dude now i know were to go but i will wait to see the new quad to make a clear choise betwen mod the ds or buy somthing new like ds 800 or 750ex or just and amiliorated 650 whit efi and reverse this would rip

 

My 730 kit with ported intake and lectron 48, stock cdi and end cap. made 59 hp on TVI's dyno with no tuning. Price is more around 2700.00 for jug and piston, carb and ported intake. also you have all the little stuff like gaskets and filter. I dont know if the TM 45 will be big enough for the 730. I had to go with the Lectron 48.
