I've done the usual stuff to my 2002 Blast: rejet the carb, V&H exhaust, K&H filter, reroute hoses, etc. I'm quite happy the results - but I want more. The question: What can I do over the winter to pep this puppy up a little more? My budget is about $300, max. (Gotta buy tires in the spring !) Thanks in advance. |

Shim needle, hi comp piston and total seal rings, hone cyl., and new seals, guides and heavy duty (say 650 lift max) springs in the heads as well. Then next year ratio rockers and a SE 550 cam. EZ |

EZ, I've already shimmed the needle as recommended. Your last post packs a lot of new vocabulary for me. Total seal? Guides? Where can I get a hi-comp piston? It looks like Revolution Performance no longer stocks them. I take it from other postings here that 'hone cylinder' is an operation that is better left to professionals. Any idea who might do that near Chicago? |

That Denso spark plug will help a bit as well. Shaving weight is a great way to increase hp. You or the bike! Rear sets will shave several pounds. |

I'm sure Rev Perf still has pistons. Ask them! You could ask at the Stormfronts section of Badweb to see if anyone in the Chicago area can make a recomendation. For $300, about all you'll be able to do is the piston. Check into a set of Pro Series or B50 cams. They were on sale (but its been awhile). That'll be about $200+ (if not on sale). See if you can do both as the cams will be easier to do if the head is already off. Setting up the head now will enable further mods, but you'll get nothing in the way of performance now. I'd be realistic on how long you plan to keep your Blast and if you'll have the money down the road to do more. Otherwise just piston or cams (or both).

The piston better be cheaper now that you can buy the whole kit for just over that. Check our sponsors, and several other folks, email me if interested - total seal rings are worth the money and are considered the most reliable. Honing can usually be done by most competent machine shops - call around - between 30 to 70 are prices I was quoted in Cali. Valve guides and seals - considered inferior to most aftermarket, The head springs because you'll want to upgrade to a better cam and these come first. EZ |

Make..A..Plan. Dont just throw money at your bike willy nilly. If you upgrade the guides, springs and valves and never do cams or even an ignition, you've wasted your money. If the 515 kit is still on sale then you'll get everything you need to do the piston, with rings, a bored/honed cylinder and gaskets (if I remember). Ask Revolution Performance (Revolution Performance) if they'll price match if you find a big bore kit cheaper. Revolution Performance is a sponsor and sponsors are what makes Badweb possible (they've been very good to me). B50/Pro Series cams bolt right in without any other engine modification and they are a good all around cam. Better (more radical) cams are available which will increase peak horsepower, however you'll get a narrower powerband. Example: B 50's are good between 2500rpm-6500rpm, B70s (SE 550) are good 3500rpm-6500rpm. So you'll lose a 1000rpms of usable (relative term) power. Get even more radical cams and the powerband gets shorter. If you increase the rpm limit of the engine (stock is 6500rpm), you'll be able to use more of the cam as peak power of the SE550s or B70s is at about 6800-7000rpm and they'll run good past that rpm in any gear but 5th. The B50s also produce usable power past 6500rpm, but 6500 rpm is about the peak. There is about a 3hp difference between the B50s & B70s peak horsepower. The B50s can also be 'upgraded' later by the addition of higher ratio rocker arms which will give more lift (but you'll need new or modified valve guides). You can also increase the redline of the stock engine by just changing valve springs and installing an aftermarket ignition. But you'll be limited to stock or B50 cams. Thats goes along the line of you can spend $1000 and be at your limit of performance or the same $1000 will be a stepping stone to more. Piston (or big bore) and/or cams is what I'd do next. Unless you can find a used/new XB top end w/ cams cheap. Thats the fast way to SE550 cams, 7500rpm redline capability and better performance. Above hp figures are not exact. If you really spend the time tuning more gains can be had. These are ballparked for comparison. |

I figured if he's budgeting - to plan ahead - lol - thats why I added the springs, seals and guides into the equation - not really expensive, then all the next step would be is cam and ratio rockers - then the 3rd year can be head work. EZ |

Not questioning your advice, just saying to be realistic. Limited budgets mean smart planning. I know what YOU would do, and I know what I would do, but WE arent the bedrock of Blasting sanity! LOL! |

For an explaination of Total Seal rings..go to www.totalseal.com basically the technology allows TWO rings in one land instead of the customary single ring...they are used only on one ring groove, either the top groove or the second groove...but not both, I use the moly top set in the nitrous motor... the oil ring will always be a stock design...it does help with cylinder seal..less leakdown and better oil control. And I'm the crazy guy...I have a mental picture of a Garrett GT1241 turbo on my bike...or is that I'M MENTAL??? If I can figure out how to oil it properly and how to work the water cooled center section thing out...the rest is doable...wouldn't need massive head work or high lift cams..5 or 6 pounds of boost would be cool |

I think what it boils down to is this: can you get cams, compression, valve springs, and ignition ALL for $300...??? probably not. ...I'm sure it's been done many times before, with very patient shopping, and probably a lot of luck too! I usually end up doing one mod at a time as funding, spare time, and reasonably good deals come along - and running around with a somewhat mis-matched combo in the mean time! If you're afraid you'll be too old to ride by the time you find a smokin deal on a good used XB front-top-end and cams, and you want something good you can start with NOW, then you could blow your whole wad (plus shipping, assuming they're still on sale) on a 515 kit... Awesome! or, you could get a mere piston kit, have your stock cylinder bored locally, and come out about $100 ahead (and minus a few cc's and sturdier jug) - which might be enough to score some used cams or an adjustable module on ebay, or enough to buy a valvespring kit and some stuff to port your head!!!
...then, start saving pennies and looking for deals on the parts you still need. |

Oh yeah - if you're going to run SE550 or XB cams, and probably this also includes the SE336, then you may want to get a new OEM XB head, valve springs & hardware, instead of reworking the Blast head - of course it also means you'd have to get an XB9 front piston kit instead of one for a Blast. yay! |

FWIW: I've gotten 2 XB heads (one used, one new complete) and XB cams right here on Badweb. All three for about $300 (3 separate deals though). Deals can be found at the Badweb classifieds! |

EZ - Do you know of any superchargers that will work with a blast? I know I've seen some musings on this site about turbocharging a blast, but this is the first I've heard of a supercharger? Just curious...I'm in the middle of another project bike which makes my Blast my primary ride right now. However when I get the other bike going again I may be looking at tearing the Blast apart a bit too. Just looking for ideas for a possible future project. |

The hardest part of supercharging the bike would be in figuring out how to drive the supercharger...would be fun for sure though. |

Paxton makes various types, including non belt drive types - lol - The hardest part of supercharging is the price of the parts - or it would have been done by now - lol - the above bike doing the salt is also an international show winner with the Salt being just a part of its pedigree - It is a total custom that started off as a big Twin and genius! Yes - it is a single! EZ (Message edited by ezblast on January 04, 2009) |

Fast - That's why I was curious if there was one made specifically for the Blast...hoping someone had figured out how to hook a chain/belt to the existing motor. I've been toying around with the idea of turbocharging in and doing some head work as well once I get another reliable bike for my main ride which may not be in the immediate future, but I've decided that whatever I wind up doing the Blast will definatley be around for quite a while. EZ - yeah, you aren't kidding. Those paxton's sell for about what I paid for the my Blast though it would be fun |
