If so how do you like it? And if eneyone has eney info on it please let me know. I'm think about building my ds into the ultimate dune/trail bike.

Thanks Luke

 

The HPR 730 is tried and proven. Can't go wrong with Eric's product. Look up OMW and see what he has to offer. Some of the stoutest builds in the business.

 

i would agree , i used a sleeve, but i know a good machine shop. and did alot of extra work to ensure seal. i had the top of my cylinder , and head tig welded, and cut new water holes , then had a custom gasket made. i had about 700 total in it , but if i wouldn't have got parts/labor cheap. it would have been easier and quicker to go with a omw, head. i did alot of extra work after hearing horror story's about leaking head gaskets.

You should learn to use spell check, eneyone is spelled anyone.

 

Pro and cons the 720 kit if done right, and IS NOT A RACE MOTOR meaning high compression , can run for awhile what I hear was the cylinder gets too thin when bored out and the pressed in steel sleeve Will egg shape after awhile, I ran a aluminum sleeved cylinder one with no problem for 1 1/2, I had a oil pump issue that caused a rebuild and found a great deal on the 105.5 cylinder (730) I tell you what thats a work of art!
Its made to be used and abused , high compression, NOS, it can handle it! if your going to do some light mods 720 can work, try a search , lots of info here, but... if your going to step up that DS spend the cash on that 730 jug, Eric or The Bom have them, keep you wallet full and eyes open never know when you may catch a deal on one like I did.

Now just a note another wild man here called Scooby ran a bored stock cylinder 105mm No Sleeve (Re-Nickel-siled) and ran for awhile unfortunately he was also running alcohol with a turbo! Kaboom!
