Found this in the knowledge vault:
In terms of timing, this is extremely easy on the Blast. If you have a manual use the instructions for static timing. If you don't here goes. Remove the timing plug found on the right side behind the pushrod tower, also remove the timing cover also found on the right side. Place bike in fifth gear and rotate engine until the timing mark is in the middle of the timing plug hole. Loosen the ignition module screws and turn on the ignition. Do not start the bike as it will puke large quantities of oil from the open timing hole. Slowly rotate the ignition module until the LED lights up I usually do this 2-3 times to make sure I don't over shoot the mark. Tighten and replace plugs screws etc. and go riding.
Problem is , I don't have the shop manual. Can some one please tell me where the timing cover and ignition module are? Don't want to make any mistakes. |

Check the Blast Specific - proceedures - section in this KV section - I will move this tibit there in time - probably after any other questions/points are resolved.

With help from my friend's brother in law - my 2002 blast is screwed
up. Anybody out there that can tell me how to set the cams? He
popped the cam cover off and now the timing is totally off.
Thanks in advance!

If its the cams that are out of time and not the ignition, the pictures in the service manual would be helpful. Did your 'friend' pull off the cam cover or just the plastic points/ignition module cover?
(note - see bottom of TKV for same - EZ)

well... The cam (right side) cover is on my garage with the cams laying in it. You can only imagine the amount of grief I am getting from the wife... tried to save a few dollars and see what I get.
I read through the manual, and it has good pics - but I wasn't able to determine how to properly align the cams to each other and to the crankshaft. Surely there's a mark somewhere... (I hope)
Please help?!?!?!
Thanks again!

OK - between the manual, the comments from Aaron in the 515cc section of this KV and here
http://www.badweatherbikers.com/buell/messages/4062/57062.html?1084197329
, the coments by Ray that I posted as a link in the Procedures section for timing, and this section really are answering your question - its just that its a hard answer you really don't want to hear - lol - the manual explains it pretty clearly - you can magnify the pics in the computer manual which should help in showing how they line up - pushrods and lifters from the top, then follow the instructions for re assembly, check your tolerences and torque values closely upon reassembly. Good luck! - If anyone has any helpfull hints outside the manual - nows the time to speak up!

I'm really curious to know why the cam cover was pulled off?
If you are planning on some upgrades, now might be the time.
EZs right.Replacing the cams involves pulling the head off the engine.There is a short cut, but that involves some cutting & about $200 worth of parts (but no head removal).
Lastly, it may be possible to weasel the cams in if the engine is at TDC and the lifters are pushed up in their bore,but its unlikely.
Sorry,I wish I could be more helpful. |

Single... don't know for sure about the blast, but it was simple on my Cyclone. The cams have an index mark machined into the gear part (looks like a punch mark, but extra deep). The location of each cam, as well as the grind profile, is marked on each as well (I have one with "4D" on it sitting here on the desk beside me, #4 cam, D grind).
You don't have to pull the whole head, just the rocker boxes. You have to relieve the pressure on the pushrods.
It takes a little time, and a few gaskets, but is not rocket science. Be glad you have a blast, it's half the work  . You will need new gaskets as well, and while you have the cam cover off check your oil pump drive gear. It's probably fine, have never heard of a blast failure, but worth looking at since you are all the way in there anyway. If it is badly worn, it is very obvious.

Thanks, all! Reep, I'll look for those 'punch' marks... the manual says red paint dots - but nada. I'll check for that. Otherwise, back to the dealer (I'm sure they will love this one)

Do you really have to destroy and replace the timing cover to replace the ignition module and set the timing as indicated in the SM? |

Well... You have to drill a hole in the timing cover to remove it. The first time I did it, I just popped it back in after I was done and left the hole. Hinda hokey, but it works. You can always just drill the timing cover for screws and use them to hold it in after you remove it. Most people buy two screws and their favorite timing cover at the HD dealer. The racers just leave them off.

other than giving you a place to insert a right angle pick to pull the cover out with does the drilling accomplish anything?
How precise do you have to be in finding 5 o'clock? |

If its not at 5 o'clock you run the risk of drilling through the module. Close is good enough but go easy with the drill. Some guys just pop it off with a small screwdriver. The hole is only for the pick insertion.
The cover will pop back on or a chrome cover is about $12 with screws (the Blast is already set up for screws). |

I have not had a chance to do the gear ratio math. At what speed in 5th would the ignition module rev limit? I'm getting poping/stalling between 75 and 80 mph. It does not happen in lower gears which makes me wonder if I'm running lean. |

It sounds like you're in 4th still--- Rev limit in fourth is around 80, Third is around 65. I wonder if your TPS is malfunctioning. |

The timing cover fell off of my 2003 Blast. Is there a certain kind of cover I need to look for, or will any covers fit that are that size? |

The cover that fell off is Blast only.
However a 2 hole points cover from any Harley 1970-1999 will fit. It should come with a gasket and 2 screws. $15 or less. If you decide to go for a cover with a design, remember that the holes are in different 'clock' locations on the Blast (Sportster and "Big Twin" are 90 degrees different too). |
