I've come across that link a few times in search of interesting things to try on my blast. It helps a lot to be able to forge things on your own. I don't have the skill nor the funds to pull some of that off. If i wanted to go xb swing arm and wheels, would it be more cost effective/feasible to have a 6inch shock absorber made to accommodate the swing arm? If not, has anyone extended the blast swing arm successfully to fit the xb wheels? And would it be easier to just replace the blast forks with xb to fit the front wheel? | ||

You can use a Blast, Works or most any 11" shock using the XB swing arm, a tensioner is already required, so that little difference is moot. There is little advantage to the XB forks versus a well tuned set of regular forks and a fork brace - except perhaps even more stability to the later - lol EZ | ||
| Blastradius |
So let me get this correct, the xb swing arm can be mount without much of a fight? I'm asking because I remember reading "super blastard" saying the biggest shock you can mount was a 6in because of height/clearance issues. Kevin | ||

Yes, you'd need a 6 inch shock. XB swingarm bolts right up and if you're willing to cut the frame, then a longer shock is possible. I dont see how an 11" shock is remotely possible unless you really cut the Blast frame. A 6 inch shock I think would be very hard to come by. We have a hard enough time to find a shock in the Blasts short size. A pull shock (tuber Buell) would probably be easier to fit, but comes with its own problems. So a performance Blast shock is $600+. A custom 6" shock with the right springload and dampening would be at least that much $$ (I'm thinking double or triple at least). Just getting something that fit would be pointless unless it actually worked well. Everything you mentioned has been done. Sometimes it just boils down to what people have available. Welder, parts, knowledge, whatever is cheaper and handy. At some point it always boils down to money. An XB with a cylinder removed is often a lot cheaper and easier to come by than modifying the Blast for the parts to fit. But most are reluctant to take a fast bike and slow it down by deleting a cylinder! | ||

Wow - my bad - but I've seen that swing arm mounted on several other Blasts as well - I'm pretty sure a stock shock was used. Damn - now I have to go pic hunting -  See - EZ | ||
| Gearheaderiko |
Looks like they extended the swingarm mount over the rear tire. Welding (or bolting) in two places-swingarm and Blast frame. From that pic it looks really easy to install a pull shock (and I'm sure there are a lot of those sitting around unused!) | ||
| Ezblast |
What we need is a good pic of a naked XB swing-arm. EZ | ||
| Gearheaderiko |
If I can get to the box, I'll send you a pic. I still cant post any pics from my iphone yet  | ||
| Gearheaderiko |
I sent the pic to your gmail address! | ||
| Ezblast |
Thanks Erik!  hmm...how much higher would the stock shock make it? hmmm.... | ||
| Ezblast |
I think its doable but would affect the angle of the swing arm - how important is that in terms of what? EZ | ||
| Blastradius |
I don't think the angle would matter much. As long as my sitting position isn't awkward. To be honest, I really just want to be able mount the xb wheels. Can the stock swing arm "fork" be extended to fit the wheels? It seems the more practical way of going about it. Kevin | ||
| Blastradius |
Bah! I think i may have made a mistake when ordering tires. I wanted to go wider, so i got the pirelli st66. Back and front. After rereading previous posts I noticed no one used the front st66 but the diablos. Will the st66 front 110/80 fit the blast? Kevin | ||
| Gearheaderiko |
It'll fit, its just not stickiest Pirelli. | ||
| Gearheaderiko |
You can modify the swingarm to fit any wheel. | ||
| Blastradius |
Sweet.  | ||

So I just installed a new Vance and Hines exhaust on my bike, re-jetted to 45/175, and the bike runs great. Damn, this thing is loud! But I'm still concerned about the exhaust gasket, which I ended up leaving out. I got the stock gasket (65324-88A) from the local HD dealer and planned to use it, but I could not figure out how to fit it under the clamp between the header pipe and the head. Oddly, I noticed when I took off the stock muffler there was no previous gasket under there either. There must be something basic I'm missing. How the hell does this thing fit? What is the trick? I read that there's another gasket available, 17048-98. Would that one work better? Thanks for your help! Tarpot | ||
| Gearheaderiko |
More than likely the old gasket is still in the head. If the exhaust is sealed at the flange, then the old gasket is definitely still in the head. | ||
| Tarpot |
Interesting! I did kind of check the head for debris, dirt, etc., but I'll pull the pipe and look again. Thanks. | ||
| Tarpot |
Sure enough, camouflaged under a ton of grime and carbon was, in fact, the old gasket. Pulled and replaced. Thanks again. | ||
| Gearheaderiko |
It's very common to miss the gasket. It blends in very well! | ||

I'm a nub when it comes to bikes so I try to do a lot of research before buying aftermarket parts. I like the idea of improving upon something but I have the sensibility not to get spend happy. That's where these used $100 (25608-03y) Pro series cams come in. I want to jump on them but there are doubts and questions on a subject(engine)I know so little about.    Is that pricey for a used pair of discontinued cams? Are these the same as the b50s? What kind of plan should I map out when improving the engine. Would it be recommended to just drop them in while getting my rocker box gasket replaced. Wouldn't the cams be better off if complimented with new lifters, valves, push rods or whatever else my go into an engine to improve performance? I don't know. Kev | ||
| Gearheaderiko |
As far as the cams go- just drop them them in while you've got the cover off, I wouldn't worry about your engine being able to handle them. You do need a updated oil pump drive gear while you have the cams out. $100 is a fair price (but I can't really tell their condition). Sure everything new would be perfect, but you dont have new cams so there isn't any point. | ||
| Ezblast |
Is the chrome like finish seam rough even to the eye and not feel, that's a worry spot. I'd at least polish it. Hard pitted - don't use. Does the vast majority of the gear teeth still look newish - minimum ware kind of thing. Yeah - get the pro-series oil gear, extends the life of the bike. EZ | ||
| Blastradius |
I haven't seen them up close. They are about 50 mins away. I'll have the seller send me more/better pics. | ||
| Crackhead |
You should defiantly need to replace the oil pump drive gear when you have the rocker boxes off. The original gear is a POS and will destroy the oil pump when the teeth break off. I caught murphy on a bad day and the teeth took out the oil pump and crank bearing. | ||
| Ezblast |
Wow - you split the case then, did you use new or used to replace the bearing? EZ | ||

Some day I should document the Frankenstein motor build. I used the "good" bottom end from the parts bike motor (after cleaning out the parts from the CP piston) with the top end from the original motor. I am slowly saving up to rebuild the original motor. Since Zippers is close to me, I think I will have them balance and weld the crank, do their magic on the trans, and bore the case for the 600cc jug/piston. I have a front XB head, but I haven't figured out who to send it too. I think I want 15deg squelch bands. I want to wait to figure out my cams. Since HD has stopped dealers from providing cores to be used by outside companies for modifications, there appears to be a surge in shops experimenting with custom grinds. It appears the shops are willing to move away from the HD sound to gain more power and quieter valve train. |
