this maybe in the wrong place (sorry if it is, the diagnosis section was closed to new threads). i recently changed the primary fluid (went with the boring HD stuff) as directed in the manual, but since, the bike will clunk from "n" to first and at times will not roll with the clutch pulled in (once in gear, the bike doesn't stall or try to move though)....what is up with that. the fluid needed to be changed (looked rough and only about 1/2 qt came out) i put in about 7/8 qt (covered the bottom tooth as directed). is the clutch not engaging fully and need adjusting or is it something with the primary? | ||

I would guess that the clutch needs adjusting... | ||

Generally speaking, Harley products dont roll well in 1st gear, engine cold and off and the clutch pulled in. The clutch tends to drag so that may be normal. Sounds like to did the fluid adjustment right but as Jprovo said it sounds like your clutch just needs adjusting, You may have inadvertently changed the adjustment when you had the inspection cover off. | ||

My primary chain broke while I was riding and smashed everything up under the cover, including the cover. I finally have the parts to put it all back together except for the Sprocket Locking Link p/n HD-38362. I can't buy this anywhere, so does anyone know the length of this thing so I can fab one at work. This thing fits in between the primary chain sprocket and the engine sprocket and prevents them from turning while tightening the sprocket nuts. Or, does anyone have a different method for installing a new primary chain. Thanks for any help. Kerry B | ||

Try our board sponsers. I think www.americansportbike.com has it. If not someone else will chime in. | ||

If the Blast is like the tubers and XB's you can make one from a piece of 1" wide x 4-1/8" long x 1/4" or so thick aluminum flat bar. Round the ends so they sort of match the teeth on the sprockets, prop it in there, and go to work. Jack | ||

LOL - you beat me to it! - from the KV - "4" long by 1 or 1-1/2" wide piece of metal that is 1/4" or so thick. The ends can be rounded a little with a file to match the gullies in the sprocket." - Concur! GT - JBOTDS! EZ  | ||

Thanks all. So 4" to 4 1/8" long. I'll see if I can find a piece of scrap and make one here at work today. Any other tips for installing the new primary chain. I've read the service manual procedure, is that the way to go? Kerry B | ||
| Ezblast |
Yes! | ||
| Swampy |
Kerryb, Where you from? What happened to the primary chain? I was told that nothing ever happens to them. The locking link can be made from steel with sharp edges like mine! LOL! | ||
| Kerryb |
OK, what's the secret. I made a locking link to put between the primary sprocket and clutch, but when I turn the primary nut, (cw) to loosen, it still turns the primary sprocket. I have the bike in first gear. Maybe I need a longer locking link? What size is that nut (in mm), a 1 1/8" works but I know it's not the right size. | ||
| Ezblast |
1 1/8 deep & 1 3/16 deep are the two sockets used in the primary. GT - JBOTDS! EZ | ||

You have to put the link in in a different direction / \ | ||

Hopefully, you've got it all fixed by now, but I too want to know how did you break the chain? | ||
| Kerryb |
Beats me! I was lane sharing at the time, going probably about 30 - 35 mph. A loud thump, the engine locked up for a second, the engine died, fluid started a slow drip from the bottom of the cover? ? ? Kerry B | ||
| Gearheaderiko |
My guess, if you bought it used, that it was heavily abused or the chain was never adjusted or adjusted too tight or perhaps you were just 'lucky'. Its just very rare for a primary chain to break especially since the Blast is so underpowered for the chain its using. "Lane sharing"? California? I cant think of a much worse time for it to go! Glad you werent hurt. Are you going to Buellton next weekend? | ||
| Buellistic |
Put an XB Primary Cover on so you can adjust your primary chain correctly, "i" did !!! By the way that is 3/4 inch play on the tight spot !!! | ||
| Kerryb |
Yeah, I bought it used 3 years and 10K miles ago. I've been riding it since my Tiger 955i was stolen and I have my Sportster apart for engine work. I recently (before the chain break) did a fluid change and the chain tension was good at that time. So I'm not sure why it broke. I wish I would have known about putting on an XB cover, I've already got a Blast cover. Won't be in Buellton. I'm looking for an XB9SX if anyone knows of one for sale around central CA. Kerry B | ||

BLASTers: Just got done changing the gearing on my BLAST and road testing ... The intent was to up the gearing to make it better for "TOURING" which some of you'll like to do ... It drops the RPM's at 80 MPH on th InterState by 500 RPM ... What "i" did was to put on a XB12 motor(engine) sprocket and primary chain ... This increases the number of motor sprocket teeth from 34T(OEM P3 stock) to 38T(OEM 38T(OEM XB12 stock) for an increase of 4 teeth ... This does not change the speedo as the counter shaft/rear whell gearing was not changed !!! As you all know you can not change the rear wheel gearing with the BELT system with out going to a chain which changes the speedo ... In BLASTing LaFayette | ||
| Ezblast |
So please tell us how it feels on take off, and how it feels accelerating, so it drops your RPMs about 500? Your seat of pants review would be great! GT - JBOTDS! EZ | ||
| Swampy |
Do tell.... | ||
| Buellistic |
WELL !!!, you asked ??? ie: normal riding !!! By the seat of the pants it feels just as strong on take off ... The vibrations feel to be less as in smoooooother ... Basicly same as a CAGE OVERDRIVE which drops the InterState RPM 500/600 REVs ... Feels realy good when running in the 3K to 4K RPM Range ... 2500 RPM is 40 MPR and 5K is 80 MPR ... You will have a HIGHER MPH in each GEAR at what ever RPM(if you have a TACH.) you shift at ... Yes, "i" understand that not everybody has a "TACH.", or running the same size tires ... IMHO a lady at 5 foot in height, weighing a 100 puunds, and realy toucked in(as in getting under the paint) could get to 110 MPH with a VERY moderatly TUNED "BLAST" ... ie: open up the OEM muffler on the right side(ex wrap header to muffler), correctly jetted carb., K&N air filter, OEM air box product improved, and 38PSI front/45PSI rear tire ... THE "REASON" "i" put the XB12 motor(engine) sprocket/chain was to make my "BLAST" more fit for "TOURING" !!! In BLASTing LaFayette | ||

Hey! Watch gas mileage for me and tell me if it changes at all. I just might do the same thing. It's a lot cheaper than that Baker 6 speed... | ||
| Buellistic |
Joey: "i" keep a LITTLE GAS-UP BOOK in my tank bag ... Keep a cloose watch on my GAS MILEAGE as it will reflect IMPENDING TROUBLE ... Will keep you in mind for a UP-DATE on the "GAS MILEAGE" ... In BLASTing LaFayette | ||
| Slowhand96 |
LaFayette I know where I can get my hands on an XB9 sprocket and chain. Will this work the same way? Thanks Chuck | ||
| Buellistic |
Slowhand96: Only the XB12 has a 38T motor(engine) sprocket ... XB9 has the same 34T as the BLAST !!! In BLASTing LaFayette | ||
| Slowhand96 |
Dang! How about XB9 cams? Will they fit? will they be an improvement? | ||
| Swampy |
Yes they will in both accounts, however you will need to improve the valve train to go with the cam to account for the higher lift. | ||

Hey guys quick questions. Just got a 2002 Buell Blast with 1400 miles and was doing the 1000 mile maintenance. I have changed the oil, changed the trans fluid, adjusted the clutch, and now I need to adjust the primary. From reading the posts and the manual I have to use a torque wrench set to 24 inch/lbs and then back off 7 flats? Two questions: 1) Where to do I find a torque wrench inch/lbs that can measure 24 lbs? The only ones I found start at 100 inch pounds. 2) what is meant by flats? Sorry I have never used a torque wrench Thanks! Trying to to do this myself as HD dealer here in Ann Arbor, MI said it would take them 15-15 days to do the 1k service and charge me 300 bucks. | ||

Tool stores usually carry them or can order them, you could probably search on line and find one as well - you could always do the adjustment by ear as well - see procedures section. GT - JBOTDS! EZ | ||
