NRHS,
I own a 04 1200R XL Sporty and I am considering purchasing your Stage 3 Heads and your 1250cc Bolt-on-Big Bore Kit.

My question is, do I need to upgrade my pushrods, rockers and tappets with the one's that you carry.

I have Cams still in the box .551 S.E. I know these are loud and make a little less power than some others but they are new and in the box with a gasket kit. I would still really want to use them.

Currently the bike has these parts installed. Mikuni HSR42 carburetor, Big Sucker Air Cleaner, Screaming Eagle Slip ons (Bassini Pro Streets on order) Screaming Eagle Ignition.

Also what gaskets any other additional parts are required, I would like to only make one order so a parts list would greatly be appreciated.

Thank you

Stock tappets will be fine, stock rockers will be OK too(though your at a point where rollers ain't a bad idea at least IMO), stock pushrods should also be fine. But again, adjustable pushrods are always a nice thing to have. Your going to spend good bucks on a stage III headjob and 1250 kit, whats an extra $100 for adjustables?

Starbuck,

EC1250R is correct in that the valvetrain components you've mentioned would be a voluntary purchase in this particular application. The .551 SE cam is designed to work with light springs and thus has a pretty smooth ramp and stay very stable to 7500 (where they rev them on the XB9 Buells), so they don't require us to put big nasty springs in to maintain good valvetrain control. Thus, the stock valvetrain isn't under a ton of extra strain and should work out fine.
That being said I agree with EC in that any of the items mentioned, and especially the roller rockers and improved lifter (JIMS Powerglides in this case) would provide good piece of mind and make for heavier duty package overall. If you do go with adjustable pushrods though I would suggest you opt for the collapsable tube set, or you'll be pulling your hair out having to pull the rocker boxes everytime you need to make an adjustment.
Outside of that all you'd need would be a top end gasket set to complete the work. We sell a very nice Cometic EST kit for $82.35.

Part #'s =

The collapable tube set is brand new and I don't have the part number handy, but when you call to place your order I'll have the details. Price in this is $149.95
NRHS 1250cc Bolt on Big Bore - Black Highlighted - $1345
Stage III CNC head prep on your heads - $1100

Drop me a line or give me a call if you have any other questions.

Thanks again for your interest,
Justin @ NRHS

Thanks for the quick reply and all the info hopefully will be calling you soon.

Debate on Hydrosolids moved. This isn't the place for it.

Since I would be springing for all the extra parts and a different camshaft would only require the head to be set up for them and the hydrasolids. What would you recommend, Camshaft wise if I went another route and decided to not use the .551's. I just want to do this once, getting as much performance out of the motor I can. Thanks

Well, our most popular combo is a set of SE .536's with a Stage 2 job on the heads. The heads you've already got are the best OEM casting. We've had lots of customers break 100rwhp using that setup with 1250 kits (with a good carb, ignition, & exhaust). The 536's keep the costs down because they're not a pricey set of cams to begin with, and they don't need a big supporting cast in the way of adjustable pushrods, travel limited lifters, collapsible covers, and roller rockers. Those things can easily add a grand to the price tag. At this level, reliability is unaffected and longevity is actually improved.

If you're up for more, though, Stage 3 can really take advantage of a lot more cam. Lots of possibilities there.

And if you're up for even more, we can get away from OEM castings and really open up some new doors. Raised ports, oval ports, altered valve angles, and so on. These are some of the things we do in the race motors mostly, but they can be done on street motors as well. It's all in how far you want to go.

I'd have you call Justin, it'd sure be a lot easier than doing this by forum or e-mail, but I see you're in Japan. Tell you what, ping Justin directly at justin@nrhsperformance.com , he'd be happy to put together an estimate or three and lay out some different packages.

Thanks for all the info. I'll get in touch with him and see what we come up with.
