We have thirty miles on the Blast. I noticed tonight that there were some oil trails on the muffler underneath the crankcase on the right side. Upon closer inspection, it appears that oil has been leaking either from the area where the wire bundle enters the crankcase or the circular cover just above.

Forgive me if I have my terminology wrong. I'm new to this. I did a search through the archives and saw a posting about this, although it was a much more serious leak. Is this a normal occurrence in a new bike, or is this something that needs to documented or addressed by the dealer?

Thanks,

bradj

Welcome Brad! Don't stress, but take it to the Dealer - a new bike should have no weeping problems - have them rectify it. Then when all is said and done - ride the hell out of it!

Thanks, EZ. I knew you would come through for me. I figured it should be addressed by the dealer, but thought that it might be a "break-in" issue.

Thanks!

If its leaking on the right side it could be crankcase blow-by leaking from the air box, an oil filter leaking or an oil line leaking at one of the oil pump connections, No? Try giving the oil filter a twist.

Brad,

First off, check your airbox like Swampy says. The airbox has the crankcase vent routed into it, and it can weep oil. That said I don't think it's your problem from the number of miles you have on the bike and your description of the leak.

To answer your question, It's not normal. Have the dealer fix it (see if they will give you a loaner). I'm sorry that you allready have an issue with your new bike. I hope that it hasn't put sour grapes in your mouth. All in all they are very reliable little machines.

The round cover that you're talking about is the ignition cover, it's commonly called the "points cover" because at one point in time the contact points for the ignition lived under there on Spoststers. The wire bundle you're looking at goes to the ignition module, which lives right behind that cover.

Under that cover, and under the ignition module is the timing rotor. The rotor is bolted to the rear camshaft. The camshaft passes through a hole and seal that is in the Gear cover. I suspect that that seal is weeping/leaking. It's a fairly easy fix. Hopefully your dealer has the parts in stock.

I was able to get better light on it after dinner. The oil is seeping/weeping from the bottom of the circular cap on the crankcase cover.

A 200 mile round trip to the dealer is in order after only 30 miles on the bike. This is not a good start, but I'm not going to freak out yet. We'll see how the dealer handles it.....

Thanks for the Blast anatomy lesson, Jprovo!

Yes, it would be nice if the dealer had the necessary parts in stock and could take care of it while I hung around in "the city" for a few hours, but I am going to assume that they won't, and I will have to make a second 200 mile round trip to pick it up. My wife is really bummed about it. She has been coming home after work and excitedly telling me that she wants to ride her bike. She is learning how to ride and was thrilled that she got it into 2nd gear this afternoon.

Came home after dinner and noticed that the A/C wasn't working...fan motor on the outside unit is toast... great. Oh, and I have that dental appointment to look forward to Thursday.

11:30 AM: Arrive at Jones H-D/Buell in Little Rock (unannounced)
Sales guy (Joe) says, "I'm sorry...I'll get that off the trailer for you and we will have someone look at right now." I go into the store and wander around a few minutes, go back to the service dept. and he tells me..."He's putting on a new cam seal gasket" (I believe that's what he said) "and it will be ready to go in a few minutes after we clean it up for you." I'm dumbstruck. I tell him I'm going across the parking lot to eat at the Hawg Diner and will be back in a few.

12:10 PM: As I walk out of the diner (having eaten a bowl of "your mama's chili" I look over and see the guys strapping the Blast to the trailer.

12:15 PM: I'm on the road heading home, still dumbstruck at how well it went. I call home and find out the A/C guy has come and gone and it is fixed.

It is sunny and 90 degrees. I think I'll go ride.

Oh yeah, someone's going to get a letter. I was treated very well today and I want them to get credit for it.

I'm happy to hear that your dealer is doing their job right. With her bike fixed, and the AC working, the wife is going to be one happy lady.

Here's one for you all. I'm getting oil seepage on the left side around the shift pedal and clutch cable. Also some around the primary cover. Its not bad, just a little annoying and makes me want to tear into it. I do have the service manual and I am an aircraft mechanic so you can see how tempting this is. Is this a normal leak or do I need to work on it? Its a 2005 that has 1500 miles put on it since the end of August.

Jeb:

On the SPORTSTER engine BUELLs this happens because the transmission breather tube is pinched closed, also if you put too much oil in the transmission... The pressure in the transmission to make it leak or weep comes from the pistons going up and down with a leaky seal
on the motor sprocket shaft... The way you discover this seal has gone bad is the oil in the oil tank drains down into the crank case from sitting(this is a common thing on H-D engines because of their design)... If the seal
goes bad the engine oil leaks into the transmission by way of the motor sprocket shaft seal... On SPORTSTER engines 28 oz of oil in trans is plenty other wise it has better chance
of weeping from the areas you stated...

I agree with LaFayette. If the crank seal was bad (been there done that) I think it would be blowing all sorts of crap out the vent (wherever that goes on an Blast / XB, I don't even know). It's very obvious on a tube framer, it ends up all over the rear inner hugger, back tire, rear license plate, tail bag, riding jacket, etc. Quite the mess.

So if it were anything but a pinched tube, I think you would see a more noticable mess wherever the tranny vent terminates, not coming out the other places. Look for a pinched (or plugged with a wasp nest, small mammals, ladybugs, whatever) vent line.

Is the shift seal sticking out at all, or look recessed? Sometimes you can get seepage from your primary adj. bolt, or drain plug and it will of course wick to the gasket from the out side - so check that first as well. If you have to reseal the primary side - its not hard - a new gasket and primary seal, some teflon tape at the base of any threads going into the case - meaning the adjuster, cable, & drain, follow the torque pattern and specs in the manual, go through a few heat cycles and repeat the torque pattern and specs and your done - in the process you will adjust your clutch first then adjust the primary. Not a hard task for a mechanic at all - just a bit time consuming, but the heat cycles are fun! I noticed the bike is brand new - if it really is seeping/leaking have them fix it!

Ed,

Here are some pictures of my weeping crank case below.

Is this a problem I should be worry about..?

I notice it two weeks ago, but yesterday when I was cleaning the bike, I notice the oil had dry up, so I though it would be good to send some picts in to help some of our fellow blasters, if they have the same problem.

Do you think I need to get a new Gasket Cam Cover...?

If its just a shadow, I wouldnt worry about it. You'll get that over time (check the crankcase halves gasket). If you actually get an oily film or you find it begins to pool and drip from the engine, then it might be time to replace the gasket.
Try torquing the cover to specs first.

not that you asked my opinion, but you got it!

I wouldn't worry about it. The gasket surfaces are going to weep... shadow, whatever, a little bit. The worst leak areas for me are the rubber plug where the wires go into the engine case for the alternator, and base gaskets.

Do I need to start planning the next SLO ride??

That engine will clean up real nice if you use the spray-on/rinse-off wheel cleaner.

Hi all, this is my first or second post here... I picked up a 2002 Blast about a month ago. It had 850 miles on it... now it has 2000 (obviously I'm enjoying the Blast ) Changed the oil and adjusted the primary at 1000.

Just noticed today when I got home that oil was leaking from somewhere way up on the front left side of the engine. Not alot, but enough to have a couple drips hit the floor. Oil wetness all the way up the black finned part of the engine... couldn't see to good, but didn't appear to be anything up higher on the silver part of the engine.

Any ideas? The rocker cover gasket? I hope it's not the head gasket...

Yep, you're right... it's the rocker cover gasket. I went to my local Harley dealer (who was a Buell dealer till a couple years ago... I think it's where my Blast originated) and they said they had the gasket kit in stock. First they gave me a box labeled for an XL. When I questioned it they opened it and, sure enough, it had twice the number of gaskets I needed. So then they looked up the single gaskets for me and got 'em together. Now that I've got my rocker box out and get looking at things I'm confused.

They sold me two nearly identically shaped gaskets: 16800-84 & 16800-84A. 16800-84 appears to be all metal, although it seems to have a very thin rubbery type coating. 16800-84A is also metal but has an orange rubber coating with some (oil sealing?) ridges molded in. (see attached pix)



Which do I use? Or am I to use both?

The orange one says FRONT HEAD on one side and REAR HEAD on the other. The ridges appear identical on both sides... does it matter which side goes up?

The metal one (16800-84) just has the part number. Number side goes up?

Managed to get ahold of the folks at the Harley dealership yesterday... they looked up the numbers and told me the metal colored one 16800-84 is now listed as obsolete. It has been superseded by the orange one 16800-84A.

Now if I can just get the time to put it back together tomorrow!
