Hello, My name is James, I own a 2010 buell xb12sx, I'm 28 yreas old and live in france This bike is a bit special since it is equipped with the RR fairings (catalyst composites kit) that I converted for road use (not an easy job)  Hella bi xenon projector, custom windshield (mold in construction) since original one has been discontinued) http://i21.servimg.com/u/f21/19/07/53/30/p1020915.jpg the bike close to a 2007 sx (bmw k1300r mirrors) http://i18.servimg.com/u/f18/19/07/53/30/p1020815.jpg Catchcan IN the swing arm http://i18.servimg.com/u/f18/19/07/53/30/p1020619.jpg [img]http://i68.servimg.com/u/f68/19/07/53/30/p1030119.jpg[/img] Superlight primary set up  and much more Since the bike is for track use, before purcchasing those parts, I would like to know if hydro solid lifters/aluminium pushrods is a reliable set up also, for easy access, can I swap the pushrods covers with the xr1200 ones, or I must purchase the collapsible kit from hammer performance ?

Who makes the "hydro solid lifters/aluminium pushrods" that you are considering? Hydro and solid are opposite terms, so the details would be interesting. | ||

Jim's usa 2015 catalog, page 52 those hybrid tappets become solid till 5.600rpm Jim's gives 3-5hp gains but they are a must have for race application | ||

I would use aluminum pushrods. They don't have the strength. Smith Brothers are the best in the business when it comes to pushrods. Hard to beat chromoly. Hydrosolids are limited travel lifters. They have under half the travel of stock lifters. The only reason I would have against them is that you have to use adjustable pushrods, at least at first, to use hydrosolids. To use adjustable, the motor has to be out of the frame so you can adjust them and seal the required collapsible pushrod tubes. Adjustible pushrods are heavier and weaker than standard pushrods. The best way IMO to use hydrosolids IMO is to set the adjustible pushrods to proper length, run the bike a bit to make sure they are right, and then pull them and send them to Smith Bros to have solid pushrods made to length according to the measurements from the adjustibles. | ||

I've used Jims in the race bikes. I spin the motors to 8200 rpm with no problems. .643 cams. Beehive springs. | ||

I just realized I said I would use aluminum. I meant to say I wouldn't use them. | ||

with some 1200's or xb9's ? | ||

Almost certainly bored out with XB9 cranks... | ||
| Ducbsa |
My buddy's new GT350 does that, but it's DOHC. | ||
| Phelan |
Yes, Slaughter runs bored XB9s. I have a big bore XB9 build coming up myself. | ||
| Slaughter |
Sorry to respond late - yes, XB9 bored to 1169cc Lightened flywheels about 2 pounds. Bored cases to accept 2008 flywheels (bigger bottom end bearings) | ||
