FE501E The Fault

Hi,

Having removed the engine from the frame. I've started the disasembly to rectify the fault that existed when I purchased the bike.

(The bike locked up when the previous owner tried to start it after an oil change)

What an amazing engine......The cylinder reminds me of the TZ250 (Yamaha two stroke) Moto GP motors I worked on in the early 80's except this is a four stroke motor that deposed the two strokes from GP Motocross!

Anyway.....with the cylinder and piston removed, I can see the fault. The counter balance is out of time and is therefore hitting the base of the conecting rod when one tries to turn the engine over.

It is not clear to me yet why this condition exists.

Has anyone else seen this happen?

I read somewhere that the counter balance in these engines is somewhat unreliable.

I'm stopped now in need of pullers. Hopefully that will be sorted out tomorrow.

What year?
I am assuming pre 2001?
If so the crankshaft balance drive gear can come loose and shift balance phasing.

Hi,

Yes a 1999 FE501E

Can you discribe how the balance shaft can come loose? Is there a key that shears?

It also feels like the impact has damaged the conecting rod / crank bearing as it feels "lumpy" when moved for and aft.

This I'm not too concered about as I intended to change the rod bearing and bushing while the engine is apart.

Thanks,

TH
 
hi. you can add your details of bike and location in your signature - it can help with replies to your posts :)
 
Hi TH,
The following picture is of a 501 assembly I have for sale.
Note the lower right hand gear in said picture. Such is simply an interference fit on the crankshaft and located by the visible crankshaft set screw.

If the set screw is missing and / or damaged the gear can rotate on the crankshaft.

Did I mention these items are for Sale? :D

My rebuild continues with new parts coming from Rick in Portland, Oregon and (just in case) I purchased the spare crank and counterblance from Dale.

I've cleaned up the cylinder head, ready to lap the valves and, as I'm a disciple of Somander Sing in India I've grooved the combustion chamber.

This process improves combustion, torque and fuel consumption.

Here is an image of the combustion chamber for those who are interested.

I have it on good authority that Samander Sing only grooves his combustion chambers because his cigarettes keep rolling away while he is lapping the valves on his RE 350.
 
When someone use's the phrase pre 2001 e-start only Exactly what does one mean?

Some of these pieces will work :lol:

There are e-start motors from 95 to 98

There are e-start motors from 99 to 00!

Said phrase can be found look it up to find the fault :lol:


HOPE THIS HELPS :D
 
Re Somander Sing and his patented grooving technology.

I too was a "doubting Thomas" until I first groved a Briggs and Stratton lawn mower engine that always needed 5-6 pulls to start it. It now starts first pull every time.

I then groved the Chevy 350 in my 1988 GMC SUV. It improved the MPG from 14.8 to 18.

I then groved my 1996 BMW R100RT it eliminated the surging issue these bikes have and, it now runs on 87 octane fuel

I'm hoping that grooving the Husaberg head will allow the use of pump 92 octane fuel instead of the recomended 98 which is considered race fuel in the USA. I've no other expectations.

re Ricks comments.......yes we found out to our detriment yesterday that the parts I bought from Dale Lineaweaver did not all fit my 1999 FE501E

I turned out that the parts were from an earlier than 1999 bike and taper for the ignition rotor was different.

Trouble is we only found this out after building the crank with a new rod kit and installing it into the crankcases.

So we have to do the work all over again.

As for the original fault with the motor, It was exactly as Dale described. The gear on the crank that drives the counterbalance had sheared it's locating pin and rotated. This allowed the counterbalance to hit the rod "big end" and damage the bearing.

The ring gear was actually split and a tooth missing. See images.

Rick stated the likely cause was a severe back-fire on start up.

I can't say enough about Rick from BOSS in Portland, Oregon.

I arrived with the intention of picking up some parts and using a couple of pullers.

Rick dove in and pulled the cases apart to ***** the issue and effect a repair with the parts I had brought together with the parts he had acquired for me during the week.

His well equipped workshop and disposition were a delight to be around. I hope he enjoyed at least some of my stories.....

I would recomend Rick and his company BOSS to any and all for off-road motorcycle services.

I'll second that. He does know his $hit and he is more then willing to help.. The guy just loves his bikes, it shows in how he takes care of our bikes here locally...

Such simply indicates the starter motor drives the crankshaft via the remote balance shaft and consequent driven crankshaft gear which failed on the engine Trevor owns.

Hi Trevor,
I understand from Rick Bozarth that you may not be happy with our transaction.

Do you feel as though you were mislead and / or slighted by said transaction?

I certainly hope not.

If you did not receive what you felt was being advertised please let me know and I shall make amends.

You paid $65.00 US including shipping.

The great value in the package was that of the "crankshaft starter / balance gear"as to the best of my knowledge production has long since ceased.

The crankshaft fits all pre 2001 engine cases, albeit does indeed have the possibility of two different flywheel tapers depending on the year (case versus cover mounted stator)

For the record:
The starter clutch surfaces showed wear, however, quite usable with precision grinding should one wish to maintain the electric start option. The balance, drive and crankshaft were all in good condition.

Glad to be of help, if in fact I was. :?

Kind Regards,
Dale
 
Dale,

I'm not sure why you wrote the message above. You had written to me privately and I'd expressed my position on the issue.

Thank you

Trevor

Hi Trevor,
Such was to give you "the consumer" an opportunity to express your opinion as opposed to Rick Bozarth speaking privately and publicly for you.

I call it damage control.

You purchased an item from me and I was informed by Rick Bozarth said item was considered unsatisfactory. Basically, I was called a liar. I do not take kindly to such accusations and since our arrangement was just that, our arrangement, I see no reason for Mr. Bozarth to state an opinion one way or the other.

You have a problem, you bring it to my attention directly. Little Ricky's public post and private messages were unprofessional, in poor taste and completely unwarranted.

Make since now? Capicse?

Dale
 
The problem I see is the 3 of you were corresponding via PM's and now it has become public and from what I can tell personal. I didn't see any personal $hit or name calling from Rick. That is Very unprofessional IMPO. It seem's like a good time to kiss and make up. Crow doesn't taste that bad once you get past the smell.. The experience that I personally have with Rick has been very professional and above and beyond that friendly and HONEST. I have only known him for 3.5 months but he treats you with respect, and as a friend he has known for years. This is rare to find in a person not to mention a motorcycle dealer.

A deal was made between two adults. Rick Bozarth included himself making such a three-way. Now you also wish to chime in? Just how is that going to help?

The following is a public cheap shot. The PM was quite graphic and the strangest part of all, none of this was any of Ricks business to begin with.

"When someone use's the phrase pre 2001 e-start only Exactly what does one mean?

Bottom Line: Trevor is happy with his purchase.

It's a shame Rick did not know the differences prior to building the first crankshaft, however, such is not my concern as I would have looked prior to leaping.

For the record:
I was under the impression the gear was going to be placed on the existing crankshaft.
