I think we're in concurrence that compression is not the issue! | ||

Don't mean to interrupt all the nice blast pics, but I just wanted to give a review of the Shinko tires that I bought this spring (much to everyone's chagrin) and maybe help out a rider looking for a cheap alternative tire option to put on their bike. I purchased the Shinko SR567F 110/70-16 front and SR568R 140/70S-16 rear for less than $100 for the pair, including shipping. Both tires fit with no problems or modifications needed. I've put around 1200 miles on them thus far, and have no complaints. Break in was fine, no problems whatsoever. They handle very well for the price, far better than the stock Dunlops that I was running. I have noticed that I can take corners faster and drive in harder than I could on the stocks. I'm not at the mercy of tar strips or cracks in the road like I was before. Handling in the rain is as good as I could hope for, it inspires confidence if you are caught out in the rain. Gravel (I have had the misfortune of riding in road construction and having the pavement disappear under me) is not nearly as frightening as it was on the Dunlops, although I would still not advise much gravel riding if at all avoidable. I have not noticed any abnormal wear so far with the miles I have put on, truthfully you can hardly notice any wear. I can't speak to the performance of other tires, but I would fully recommend these tires to anyone looking for a cheap tire to put on their bike. I would not hesitate to put these tires on my bike again. | ||

Pictures or it did not happen! - lol What I did today -  EZ | ||

Had to turn the needle 3/4 a turn in to get the middle end rich enough, still working on idle af - too high - must adjust idle air screw out more turns, and turn high jet out more turns as well - turned it too far in - lol - still I must say tuning with an af gauge makes it easier and the tuning itself is easy - turn some knobs, or remove top and turn needle, and set needle. I'm done with the needle - it's stays between 13 to 15. Just sorting out idle and wot/top end - both of which have their own circuits - lol. EZ | ||
| Ezblast |
Tunning continues - notes - this is a performance carb and as I've been told by their mfgr is thus tune differently - they have a common idle that is 10.5 to 11.5 af that idles at 1500 to 2000 rpms - definitely something to get used to, however, if you remove the air screw you can get idle to 12.+ af - which acceptable to me since I run the Denso racing plug - a regular plug would be iffier - so you definitely want the racing plug. I was a tad rich on the low so went back one-quarter turn on the needle - 13 - 15 - acceptable. Each test now includes dialing in the top end - which was first too lean, now a tad too rich - slowly dialing it in. This carb responds so fast to input from throttle that the wb af gauge has a hard time keeping up and it is wonked with the sudden changes, but settles back in in consistent throttle and even throttle usage so that I can get some real readings. Everything is very crisp, setting idle rpms is the biggest hassle - but I'm close now. EZ | ||

Old School Ignition. So I am in the garage with old timers, talking about the blast. The conversation reflects on the "old" singles, what made them great. Why their sound was unique. The question came to me about Ignition. They wondered what the blast would sound like with old school points. I said, can't do..the cam turns Counter Clock wise so the HD point flyweights wont advance. So they wanted me to post...Is there any foreign flyweights that work CCW? Maybe a complete point set up? They got me wondering about the sound | ||
| Gearheaderiko |
Blast cams are Sportster cams, when did they start turning sportster cams backwards? | ||
| Gearheaderiko |
Points won't change sound. Unless you're really down tuning the engine. | ||
| Jadow |
With the question of Sportster vs Buell cams. In the old days ignition was driven off Cam 2. Blast runs off the Intake Cam, which if it was a Sportster, would be Cam 3. Cam 2 rotates clock wise, Cam 3 CCW. Yes you can use XL cams. But installed differently | ||
| Gearheaderiko |
I run sportster cams and I don't remember anything different about them. Some Blast cam covers have spots for 4 cams and XB cams also bolt in. I'm really not seeing how any of what you say is possible. The Blast is literally a sportster minus one cylinder. | ||
| Gearheaderiko |
I'm also running a sportster ignition, which if the cam was running backwards would totally screw up advance. | ||
| Jadow |
Thanks GearHead for the correction. | ||
| Gearheaderiko |
I'm hoping we got it cleared up  | ||

"Points won't change sound. Unless you're really down tuning the engine." When I pointed this out on another forum, I got blasted about spark energy and spoked wheels and what-not. | ||
| Jadow |
Don't worry about it Jetlee, Some of us "hear" a different drum....I installed a New battery in my hearing aid and now it all sounds the same  | ||
| Gearheaderiko |
Yeah well, despite the actual truth to it, I've changed from points to electronic ignition on quite a few vehicles and it has not changed the sound at all. Now if you can increase the plug gap, increase the spark voltage, alter the ignition timing and curve and adjust the fuel mixture, sure it will sound different. But you can do all that AND stay with points. But you and I know the truth Jet Lee, sometimes you just shake your head and move on!  | ||

Hey guys, This site is awesome. I've owned my blast for about two years now and what a help this site has been. Thanks for having it available. I have a 2001 blast, paid $650. Came with a ton of issues which I ended up fixing myself with the help of this site. I currently have a weird issue though that may be related to the boot but not sure. Basically in the morning and after the bike has been sitting for a while, it starts fine with no issues (yes it STARTS fine when cold). The issue is starting her while she's hot. She just doesn't do it. For example, when I turn the bike off at a gas station or parking lot, getting her to start back up is a huge problem. I thought it was an auto enricher problem so I took a spare AE I had and turned into a manual choke and nope, issue starting hot is still a problem even with the choke on (and I have adjusted it so that the choke port is wide open). here is the bike on youtube if you are interested in hearing her. She's got a buell pro series intake and buell pro series exhaust for the blast https://www.youtube.com/watch?v=Ba-rmokiGbo Any ideas guys? Could it be a boot problem? | ||
| Reepicheep |
It could be a jetting problem. Double check the current low speed jet in there, and whatever the blast folk are recommending as a starting point these days. | ||
| Ezblast |
Low - best would be a 46 but a 45 would do as well. http://cv-performance.com/harley-pilot-jet EZ | ||

Hello all, I haven't been giving the Blast much attention lately as I've been riding my new Ninja. I finally have some free time and spare cash so I am planning to get the xb9 cylinder, piston, and cams. So I have a few questions for our resident master blasters. 1) I think I remember reading that the xb cams fit in the blast head. The parts department at HD says that the blast and xb heads are the same part number. Is it a match or are modifications needed? 2) Is the stock ignition and timing good with the xb cams, or is there a better option? 3) Would 45/175 jetting be a good fit with xb piston/cylinder, pod filter, and jardine exhaust? Riding anywhere between sea level and 3000 ft. 4) Will exhaust head pipe mount in the same position as with the blast cylinder? And thank you for all of the help, both previous and future. This website has helped my little blast come back to life. | ||

So I’ve had a busy summer. Heck the last couple years have been pretty wild. My family decided to step down to one car. I tried biking to work through the winter of 14-15 and it wasn’t that bad. I bought studded tires for a pawn-shop-find GT Karakoram MTB and have been bicycle riding to work approaching 2 years. I’m in WI, so, yeah. We really have a winter. Coldest day was -20F. Hottest ~97F. In thunderstorms I’ll take the city bus. I’ve been on the Blast a fair bit this summer as there are some times I need to go 20 miles and don’t have 1.5 hours to get there. Last night I rode in a moderate rainstorm to get home. Bike worked perfectly. All good there. In fact, if you are looking for a nice Buell catalog item to add to the Blast, let me recommend the Ulysses handguards. I came to the Blast from a KLR 650 and really liked handguards. They might seem silly, but man are they nice. My question is about rain gear. What do you guys do about that place where your sleeve and your glove meet? I wear large heavy rubber work glove that can go outside my sleeve or tuck inside my sleeve. If it goes inside the breeze blows drops UP my sleeve. If it goes outside, then when I stop at a light, the water runs DOWN my sleeve and into the glove Am I missing something? "Bad weather bikers" -How do I better handle bad weather. ________________________ Firing Order: 1 | ||

XB cams fit the Blast, but you need to modify the timing rotor notch-easy. B70 cams are almost the same and Screamin' Eagle 04' cams are exactly the same and bolt right in without modifying the notch. Blast heads and XB heads are VERY different. Don't trust anyone at HD for information. XB9 pistons must be used with an XB head (9 or 12). Stock ignition and timing is okay, but stock XB heads are "stage 2 light" heads and are good for 7500 rpms. The XB cams don't peak until 7200 rpms (appx.). So a different ignition is needed to make full use of the cams and head. Stock blast ignition only runs to 6500rpm. I'm not sure at this point if any or what ignitions currently "bolt right in". But there are plenty of ignitions that will work. From $100-$400. Some may take a few more parts and thought process to work, but it's all the same basic principles. Jetting is going to be leaner. The 45 is okay, the main may go all the way down to a 145. You will have more power and better mpg! 2 minor modifications are needed to run the XB head: The front "do not remove" bracket will need to have the cam side hole elongated. The top tie bar will need a 90 degree bracket made. Both are very easy and don't take special tools. The stock lifters will work, but if you go to semi solid lifters, it's advisable to go to adjustable pushrods (opinions/knowledge may vary on this and since I run adjustable pushrods, for a variety of reasons, it was a non-issue). It is worth the conversion!! | ||

Gloves over the sleeves is a far better solution. Good gloves that cinch 3 or more inches above the wrist. My TourMaster gloves have a drawstring above the wrist that works very well. But the key is gloves that still keep you warm even when soaking wet. It is almost impossible to stay completely dry in constant rain. One piece rain suits are best. Elastic or drawstrings at cuffs. Good gear is expensive. Cheap gear can work, but often has drawbacks in function. | ||

hey guys so regarding my blast not starting when hot, I tried the 46 jet as suggested and didn't make a difference (it turned out that it already had a 45). Just for the heck of it I tried a 48 jet and now she actually starts when hot but idles very very slow (like the engine is barely on). But at least she does start. When it is idling that low, if I roll on the throttle ever so slightly then, she picks up the revs and idles normally after that. On the other case If I roll on the throttle too much and too fast while idling this slow, she turns off and sometimes white smoke comes out the carb and the carb pops out of the manifold. Other than that she does VERY well on the road. The blast is a hoot! Any ideas guys? | ||
| Gearheaderiko |
Well, rolling on the throttle while it is loping along at a slow idle will cause most bikes to backfire. Since you've blown the carb off, you might want to check the boot. If you haven't checked or replaced the spark plug, I would do that too and if it's 10 years old or has 10,000 miles on it, definitely replace it. Get a good plug. Make sure the vacuum nipple is plugged. You shouldn't have a hot start problem with a manual choke. The 48 jet is making it very rich and "choking" it. Blasts are notorious for having a hot start problem, but a manual choke usually eliminates that. | ||
| Blastjedi |
Hey Erik, Thanks. I put in a brand new NGK Iridium spark plug in there towards the end of last season. I think is the one recommended somewhere else on this site. It has worked well. The vacuum nipple you are talking about is the one that gets plugged when 49ining the bike right? That one looks good. I sprayed starting fluid around the boot and there were no changes in idle. So i take it that everything is OK? I've heard that this doesn't always diagnose the problem correctly. But works most of the time right? Still something is making the bike idle lean... even with the 48 jet. I've managed to get rid of the starting issue while hot for the most part but I had to back out the idle mix screw to like nearly 4 turns (it's got like 3 and half now). That means that the pilot jet is not supplying enough fuel or no? I'm not sure what's going on. The bike runs fine on the road... she even has a little more pull now after those changes. Do you think I should go back to the 45 jet and mess with the idle mix screw some more? Any other ideas are welcomed. Thanks! |
