what I have read the blast uses the same lightning head the tubers did.. but with a thunderstorm piston.. go figure nrhs has stated a stage 2 lightning head flows bout the same as a stage 1 xb head... I need to find an xb head cheap now got my blast tore down to a bare frame ready to be repainted. and a bare motor | ||

WiseCo pistons. I did just get off the phone with Andrew at Revolution Performance and they are indeed using Wiseco pistons in the 515 & 600 kits w/ millenium cylinders. I asked about the CP piston ring landing failures and mine was the first he had heard of. He also agreed with detonation as being the cause of it. Both the 515 & 600 kits are supposed to be 'bolt on', "but its always a good idea to check clearances". So, I'm still without an answer as to why what seemed like a common occurrence of failures in the CP piston 515 big bore kits and why such a failure in run of the mill Blast installations. The common denominator is the CP piston. Maybe just a coincidence?  I know I spent a lot of time dialing in my engine, an engine that had run before without incident in an almost exact state of 'tune' (the rings finally wore out). I'd (if I were someone else) probably run just a 515 piston with a stock cylinder overbored .063, and save my money (unless of course the price is close). I'd (if it were me) spend the money on the 600 kit. On a further note he said there weren't any stock part options for going 'big bore'.  I'm sure there are other ways it can be done, but then you're talking more $$ than just buying the 600 kit. PS Case boring for the 600 is currently $325. I'm also running CP pistons at a .015" overbore in Blast and XB head configurations without any problems. | ||

Front XB head pt #16872-02 $370. It includes valve guides and seats, but doesnt say anything about valves and springs. I'd have to imagine you can order it complete? Front XB head pt#16872-08 $288. I dont know what the difference is in a 2003 head and a 2008 head, but its almost $100! Many of the parts are the same pt# or interchangeable, including exhaust seat, valves, springs, retainers, gaskets, seals . | ||

With the Niksil liner and the Wisco piston, properly put together, all you would need to do is change rings periodically, and clean the piston. that could save you a lot of time and money in a very long run! I think a Revolution 515cc kit and XB head would be a killer combo - with either of these 3 cams - B50,B70, SE550, and Ratio rockers 1.725 - definitely a durable combo for performance. EZ | ||

Erik's idea of the XB9 front head and piston along with XB cams is a great one. Simple, cheap, and reliable...(the XB9 top end is a direct bolt-in)...except for the front hanger mount...the stocker can be slotted, or you can use the blingin' billet mount from nhrs. | ||
| Styxnpicks |
its official.... just got a set of xb cams darkside here we come! | ||
| Gearheaderiko |
Nice  Did you get a good deal? (I'm not asking how much) There are little shortcuts to a few things you'll have to do to make it all work. Please feel free to ask or pm, if you dont see it here on Badweb. | ||
| Styxnpicks |
got a pretty good deal.. got the whole cam/oil pump assembly cheaper than I could buy b50's new... I'll end up selling off the rest of the parts I dont need on ebay. I'm interested in these shortcuts you speak of.. specially if it concerns saving $$$ I dont mind paying for stuff if its worth it but I'm also trying to keep things in perspective.. so a 600cc motor with a lightened crank isnt happening | ||
| Ezblast |
I think Erik is referring to a timing cup mod when using the XB cams. EZ | ||
| Gearheaderiko |
Timing cup mod, top tie bar link, front engine mount. The shortcut is in not having to figure out the fabrication yourself. All three are posted on Badweb ....somewhere! Ignition also, are you going to raise the rpm redline? The XB cams peak past the stock Blast rev limit. Also, if your using stock XB cams, dont get talked into 'upgrading' to heavy duty valves and springs. The stock head valvetrain will run to 7500rpm, which is past the peak horsepower and the cam really starts to fall off after that, so heavier springs and valves is waste of $$. Also an advertised stage 2 'light' on other heads includes using the stock XB valves and springs. Once you switch to heavier valves, you'll no longer be able to use stock parts (which are inexpensive).FYI. Lifters too? The XB cams can (reportedly) be run with the Blast stock pushrods and lifters although the base circle of the XB camshaft is smaller. The stock lifters should compensate for the difference.And those who know me know this is coming Now's the time to consider better lifters and adjustable pushrods w/tubes. You can change them out later with minor rocker disassembly and cutting the pushrod cover out (but its easier to do when its all apart). Sounds like you got a great deal. They are out there! I've seen heads on e-bay lately. Sometimes you have to buy 2 though | ||
| Styxnpicks |
yup oil drive, cams, lifters, timing plate, cover, ignion module, timing cup and oil pump... basically the whole right side I hate cutting corners but I'm also on somewhat of a budget.. | ||
| Crackhead |
i might buy the timing plate, cover, ignion module, timing cup from you. I am thinking about an EFI project this winter. | ||
| Styxnpicks |
send me a pm with an offer and I'll hook ya up just sourced a xb front head for a good price.. no valves or hardware tho.... I think its time to make some calls | ||
| Styxnpicks |
ugh.. got over $2000 into this already and i havnt even got the headwork or piston kit on the bill yet. I really need to makes those calls | ||

hey guys, im looking at picking up a 515cc kit in a few days, and im trying to figure out the best course of action for install. should i just set a jack under the engine so i can pull the engine mount off, head and jug, replace with the 515cc kit and put my head back on? this is pretty much what i did when i went xb heads/jugs on my S1 also, anyone know if there is a new/used kit that anyone wants to unload? lastly: is there a company located in AZ that i can pick the kit up from? Im in california, and since my state is full of retarded liberals and boycotting AZ i thought id try and purchase there to do my part :P | ||
| The4ork |
oh also, is there an aftermarket front engine mount? mine has just about 9.5k miles on it and its already tore up | ||
| Ezblast |
The4ork - you can get the kit from either asb, JT&S Performance, or Millinium Performance - stay away from the CP Piston and all should be good - Mount - the new replacement kit should hold up, a beefy unit. EZ | ||
| Buellistic |
The H-D BIG TWIN "ISOLATOR"(FRONT) should work as it holds up on the 105 CI engines ... If it does not, add Drag Specialties Limiter #DS243535 an it will for sure!!! | ||
| The4ork |
what is a CP piston? | ||
| Gearheaderiko |
Yes, just lower the engine. I'm not sure which engine mount you mean. There are several different isolators available and I think an aluminum mount to replace the "Do Not Remove" bracket ($160). Questions: Have you used the 515 (big bore) kit on your S1? Are you going to use a CP piston? If you're going to use a CP piston, I'd get the biggest oversize you can buy (but NOT the 515) and just bore the cylinder. I've used CP pistons with great success, but I've seen too many CP 515's go bad, quickly. I'm a little paranoid. If your not using a CP, nevermind! I dont know of an AZ dealer, but if I did, I'd sure tell you and use them myself!

The cylinder has melted aluminum on it and the piston is missing a ring landing.Other than that, its fine! I'm going to move these posts to the 515 thread. | ||

CP pistons are out of Irvine, CA. They are usually sold under another name (such as "Hurricane"). You'll have to ask the vendor what pistons they use. | ||

Bump? | ||

uhhh i have no idea what a "CP" piston is, but im looking at the 515 kit from NRHSperformance.com $350 is a pretty good deal, with everything included, all id need is a new rubber isolator (one by the oil tank) and to have the stud repaired in my head. so for just over $400 i could do a pretty good upgrade. but my unknown is, will i see a big difference? because when i upgraded to the the stg2 xb heads on my S1 i saw no difference, just a light increase in power after a rejet and was severely let down. just wondering if its going to be the same deal. looks like the hurrican piston (which may be the cp piston your referring to) is only $155 and iirc its a 'drop-in' with new gaskets, lighter piston and raises the compression up from 10:1? to 10.5:1 just trying to weigh my options here, $400 budget is about right for a bump in power for me right now, figured the 515 kit was the best bang for the buck. but im open to sticking with a standard bore and maybe going with a cam and ignition, which do you think is my best option? i have to pull the head anyways to get my stud fixed by a machinist, so either way im looking at at least having to buy a gasket kit | ||

My opinion: The 515 is going to disappoint you. I think you'll appreciate an extra 1000 rpms (7500 redline) than the big bore. $350 is a great deal, I'm just very skeptical about the CP 515. Its also only a .063 overbore as compared to regular piston oversizes (.010, .015, .020, .030, .040 etc.). It seems a real gamble. Buy a high comp piston (10.5:1). Modify the head while you have it out for high lift cams (XB cams or B70's or better) and get some beehive springs. ($130 from revperf). Save for an ignition. ($80-$400) The best single improvements (besides a 600 kit) is an exhaust, followed by an rpm redline increase (but you'll at least B50 cams to see any real power between 6500rpm & 7500rpm). Anything else is baby steps. The only reason I ever used a 515 was that I only had 4 days to get a racebike back together and buying the kit was the fastest way to get parts. Again, my opinion. iirc=? | ||

I'd go for that! Verify the Wiseco piston (they also told me it was now a Wiseco piston). 515 kit: $375 10.5:1, gaskets & bore: appx $250 It's still not going to be that much of a jump in power from a standard overbore, but I have much more faith in the Wiseco 515. | ||
| The4ork |
what do you guys reccomend for an ignition, i need one for my blast and my s1 | ||
| Gearheaderiko |
Does the S1 use a 'nose cone' ignition (the entire module is under the timing cover)? The first I'd recommend is the "Twin Tech" module or if Crane Cams has the same (or close) module as the Screamin Eagle module (Crane reportedly made the SE Blast/Sportster module).They should be the least amount of trouble. I'd call them both. Ask if the TPS is a direct hook-up (probably need a VOES or just omit it). Also ask if the auto-enrichner will still work. Thats the route I'd go if you want to use the same ignition for both. There are plenty of ignitions for the S1, the Blast is the one that will be the trouble to find, thats why the TPS and enrichener questions. The S1 doesnt have them. *Just about any HD/Buell 'nose cone'/timing cover ignition will work on the Blast (or S1). It usually means omitting a couple wires, using a modified twin timing cup and adding a VOES (if desired) and a choke. Some SE ignitions (NOS) for Sportsters can be had for a little over $100. If you convert to an external module ignition (maybe the S1 uses that style?), there are more and cheaper choices available. Its all in how creative you want to be. Unfortunately there isnt a direct plug-in available for the Blast anymore. You might find an old (new old Stock) #32942-02 module out there, but I've already had 3 go bad. So like the CP 515, I think its a gamble. http://www.badweatherbikers.com/buell/messages/201 64/59815.html?1274563024 | ||
| The4ork |
oh i see, sounds complicated. whatever i do i want the thing to work as stock, which means the enricher and everything needs to work. if im on the blast its because most likely the s1 is down for maintenance, and the last thing i want to do is mess with the blast! so if there is an ignition out there that's plug and play for the blast (which sounds like there is not) i guess a moderate cam grind and springs may be the way to go at this point, since i cant feasibly raise the rpm limit without a proper ignition system i guess. kind of disappointing in the mods department, sounds like i got into blasts too late in the game | ||
| Gearheaderiko |
Yeah, its not plug and play Its not that complicated either (but I've done it a few times). If you can get a non-Blast CV carb (with choke cable attached) it makes things easier since you wont need the TPS or enrichener. Twin Tech makes the timing cup mod very easy and they sell the coil too. The Twin Tech timing cup mod also makes any other twin ignition work. Sorry for my long posts. I've been obsessing on Blasts a tad too long and have found many ways "to skin this cat"! |
