XB with XB - no 515 kit - nespa? GT - JBOTDS! EZ  | ||
| Gearheaderiko |
But there is an XB piston available for the 515 kit. He just has to ask if it will be included for the same price. Buying the XB head (complete with valves right?) is the short cut to getting a 7500 rpm redline and bigger (I think they're the stage 2 size)valves along with the ability to run the XB/SE 550 cams (about the same as the B70's).The XB head has more cooling fins and better flow potential (reported). The XB head is supposed to bolt right on using the stock pushrods and lifters. You'll have to make an L bracket to mount the middle top tie bar (the twin head has a different boss) but thats not hard to do and I know some who actually run without it. You'll also have to elongate one bolt hole on the front engine mount. As I just posted above (double check with whoever sells you the cams and 515 kit) you dont have to get the adjustable pushrods and tubes.It always been my advise to do that because if your going to make further engine mods, make repairs or if there is a valvetrain related problem, it will make life a whole lot easier (a small amount of money well spent). Since I am using Jims lifters they state adjusting the valves every 2000 miles. It also seems that the exhaust valve does tighten up and all clearances will change over time (the stock lifters adjust for the clearance changes, but the Jims lifters are more like solids and wont take up as much slack). It should be noted that my engine does spend the majority of its time running hard between the 5000-7500 range. I dont necessarily favour one head over the other, there are just different points to consider with each. | ||

I've been mulling all this stuff over. Revolution Performance has a $375 deal on their big bore kits. The 600 is looking too good. I'm thinking it's time for me to really get into my Blast, since it's going to hit 30K soon. So the question is, what's a ballpark estimate of time for me to get the case out of the motorcycle, taken apart, readied for boring? I'm a competent mechanic, but I've never done this particular sort of thing before. Am I running this topic into the ground?  I know I wanted to do this before, but it never panned out. I'll be ordering my big bore kit as soon as I get the insurance company to settle. That could be as soon as Monday... Thanks everybody who's answering me! I wish I had found this web site when I first got my Blast in Feb. of 2001. | ||

Am I running this topic into the ground?" Heck no! You learn, we all learn! Its of mutual benefit to discuss this. You can spend $2000 or $1000 and wind up with the same (essentially) mod. One may be more durable and one may lend itself to further mods more easily. Engine teardown: you're probably talking a good 8 hours. (yes,it can be more or less depending on experience). If this is your first m/c engine and transmission you'll want to mark and organize everything. The tranny cannot be pulled out separately, it comes apart with the cases. The cases also may not want to split easily.Study the manual first. You're at the point I was-Its the same price for the 600 as the 515, so why spend that money on the 515? Also remember you're going to have the entire engine apart, what else will you want to do now, that may be impossible or difficult to do once the engine is back together? Flywheel lightening/balancing (while, technically a single cant be balanced, there are many who have an idea of what ideal weight ratios are), transmission gearing changes, 6 speed, cams, engine to tranny sprocket ratio changes, pushrods,etc. I could go on. I think going to the 600 is your best power gain and potential. Think everything through. You may also want to ask how much it will cost for someone else to split the cases to do the bore (just so you know). | ||
| Joey |
Cost for someone else to split cases and bore? Does that include me having to take it apart again and repair/replace stuff they messed up? I have never had a single fix go right the first time on my Blast. That includes tire changes. The one time they got the balance right on the first try was the one time I had them change my clutch cable. They put the new one on without an O-ring. These guys weren't even HD, so apparently HD does not have a monopoly on lacking attention to detail in Delaware. I could call Mike's Famous in Smyrna just for giggles, but I'll be doing it myself anyway. That'll make it much more fun! Since I don't really want to go more than 100mph, I think I'll leave the gearing alone. Eventually, when I can do 7500rpm, I should have enough speed to keep me happy. Big bore: I've decided (at this moment, at least) to go with the 600. With the boring of the case, I'll probably have just enough cash to upgrade the cams and the oil pump gear. Without any other changes, I should find out if this is OK to ride. Head: Stage 2 on my head will be about $525 plus shipping. A complete stock XB head is $400 plus shipping. I would like to keep a similar power curve to what I have now. I don't need to race. I just like to have more power in reserve when I twist the throttle. Tell me if I'm right: When it comes to heads, if I plan to go stage 2 and be happy, I will get better results than going with stock XB. The XB head would be a good choice if I was going to go stage 3 and push things to the limit. With my current understanding, here's my plan of attack: This winter: 600 big bore kit with regular piston, cam upgrade, and oil pump gear upgrade. Next winter, or after tax time: Stage 2 head, ignition upgrade, pushrod upgrades. If I don't have to, I'll not change the pushrods and stuff until I do the head. Time to send email to the guys at Revolution Performance and ask them detailed questions! Did I miss anything? | ||

If your going to split - then change main bearings - It was done as a matter of fact both times mine where done, and at least look into the new stock XB tranny which is ultra slick and a great improvement in shifting. Have the piston at 10.5 comp., use Total Seal middle and bottom rings, regular top - what cam are you going with? - use Irridium plug. Base line at 45/160 jetting. Enjoy! GT - JBOTDS! EZ | ||
| Joey |
I haven't decided the cams yet. I want to keep a similar power curve. I'll put the main bearings on my list, and find out what an XB transmission is going to run me. It'll drop right in? I think the kit includes everything. Are you saying I should get a different set of rings? NRHS's tech section on installing their new jugs, and you'll see what I've learned. Will I be doing well to stick with their procedures? (Message edited by Joey on November 05, 2006) | ||
| Ezblast |
If they are installing, don't worry, tranny would be a bolt in - lol - I mentioned the rings if you are doing the assembly. GT - JBOTDS! EZ | ||

Concur with EZ! I wouldnt bother with the XB head if the Blast head is $125 more. You'll be getting the same or better set up. The transmission changes would be examples like going to the updated XB tranny (as EZ posted) or making the 1st gear ratio closer to the 2nd gear ratio (less clunk, better shift). Besides taking a slightly different route, I got an exceptional deal on my XB heads which is one reason I went that way. I think the 600 will make you happy. I mentioned someone else to split the cases, because I've seen it all to often that people panic once they get that far in over their head. Just trying to give you the heads up.(I too have very little faith in others work). | ||
| Gearheaderiko |
PS XB or Baker tranny will probably blow your budget and while they'll fit, they wont just 'bolt right in' without some minor changes. | ||
| Joey |
Me panic? If I get to that point, I usually just walk away and leave stuff for a few days, then go back to work again. I'll do main bearings, oil pump gear, and such, but I think I'll just check my current transmission for mechanical soundness and call myself happy. Thanks, everybody. I'll talk to the revperf people about sending me the big jug, and go from there. | ||

so uhh.... how well would the stage 2 heads, 515 kit and b50 cam combo work together? I'm planning ahead for next winters project already  | ||
| Ezblast |
Go with the SE cam instead at that point and enjoy! GT - JBOTDS! EZ | ||
| Styxnpicks |
so whats the difference between the b70 and SE550 cams? got a link to those SE550's I was gonna bid on the pro series cams on ebay and then I was like "ok I'f I have to pull the head off, might as well go all out" I'm not looking for an extremely wild crazy setup, just something to give me little more pep on the daily commute (half stop and go half WOT in 8 miles) | ||
| Ezblast |
The B70 are definitely performance cams and a little rougher on the drive line, while the SE will give a definite performance boost with a gentle ramp and still be gentle to the drive line in comparison. The SE are stock in the XBs. GT - JBOTDS! EZ | ||
| Styxnpicks |
got a P/N for the cams I have a H/D buell stealership prety close to here. I'd love to go wild but I just cant afford it, but I would like something a little more wild than the pro series I/E and a rejet. reliability is also something I want to keep, since this is a commuter | ||
| Ezblast |
http://www.nrhsperformance.com/partscamshafts.shtm l They sell the SE for the Blast - yes it is a bit more, but definitely worth it - its not wild - it will perfectly complement the rest of your bike, and you'll swear that this is how Erik Buell should have sold the bike! GT - JBOTDS! EZ | ||
| Styxnpicks |
so besides the stage 2 heads, 515 kit, and SE550's is there anything else I should stick on the shopping list? like push rods, lifters, SE ignition etc etc? If I have to pull the entire bike and engine apart I wanna make it worth my time and do everything right the first time while its apart | ||
| Ezblast |
Stock push rods will still work, the ignition would be nice to up the rpms to around 7500 - stock will work though, the new oil pump gear would also be smart addition - since your in the cam side anyway - thats about it - sounds like fun to me - enjoy! GT - JBOTDS! EZ | ||
| Styxnpicks |
so now the big question is... which ignition should I go with? | ||
| Ezblast |
SE if you can find it or get the Crane if you can't. GT - JBOTDS! EZ | ||
| Styxnpicks |
basically something that has the adjustable curves and rev limit I take it?..... actually that adjustable rev limit will come in handy during break in since I have a hard time keeping the rpms down I think I might be joining the dark side | ||
| Ezblast |
Welcome to the Dark side! - lol - we sell milk and cookies with our evil ways - lol GT - JBOTDS! EZ | ||
| Styxnpicks |
oh ya..... one last question for ya EZ, how much different does the dark side blast sound from say the pro series blast lite flavor? | ||
| Harsblast |
i also was looking at the big bore kits for the blast, i have spoken to both revolution and nrhs and the revolution techie that i spoke to seem to be more knowledgeable about the whole thing what he basically said is that i would send him the case,crank and head, they will do the necessary work and everything else would be from their kit the other parts needed would be a carb and an adjustable ing module i also use my blast in the summer as a commuter and this to me seems to be the best package for reliability $3000 was to much for me | ||
| Ezblast |
The sound is more of everything - you hear everything happening in the head much more clearly, the high comp. piston makes the eng hesitate for a sec when starting - the chuff on turn off on the carb is much more distinct and the power is more as well - I have both flavors - the red be the pro-series style - my daily driver - is fun yet still tame in comparison to the black bike - the consoling point being that it is never seriously embarrassed either and it is daily driver/stock almost reliable - the red bike is nice, warm and fuzzy - lol - the black bike always surprises folks - its acceleration and handling able to easily keep up with the bigger bikes on the freeway and twisties now and is unique (though both are really being Buells). GT - JBOTDS! EZ | ||
| Styxnpicks |
theres noway I can keep up with my buddies on the freeway.. ones got an 01 R1 the other has a 06 GSXR. now the twisties are a different story as they found out | ||
| Ezblast |
LOL - I was referring to steady state high speed cruising and lane splitting - all sluggishness is gone and the bike responds well - still no challenge to a 600 super sports, but easily as capable as a KLR, BMW, or other non-super sports singles and even some twins - me and Scott, Erik and John - last two of SFMC and one riding a X1, the other riding a S3 - where easily splitting at 70 plus and quicker, I still smiled and told them that they can go quicker please, since I have - lol - the Black bike is no longer lost till way past legal speeds - distanced occasionally, but not lost. GT - JBOTDS! EZ | ||
| Styxnpicks |
as long as I can keep up with triffic on the highway, theres nothing worse than that "I think I can" feeling triying to chug it uphill with some douche on your tail in the slow lane... I swear my truck is faster than my bike | ||

"so besides the stage 2 heads, 515 kit, and SE550's is there anything else I should stick on the shopping list? like push rods, lifters, SE ignition etc etc? If I have to pull the entire bike and engine apart I wanna make it worth my time and do everything right the first time while its apart" Consider getting the adjustable pushrods and collapsible pushrod tubes. It will save time if you want to do further mods, maintenance, engine repair or diagnostic work. Jims hydrosolid lifters should also be considered since if you're going for a new cam, you should get new lifters. Some adjustable pushrods are listed as 'fast install' meaning they can be installed without pulling the rocker cover but there seems to be some discrepancy between vendors as to whether they will work on the Buells (as fast install). I haven't pursued them, but will in the future. The ignition can be installed at any time so I'd put that last on your list. |
