1988 400WR timing

After searching and finding nothing, can someone please tell me the ignition timing for my 1988 400WR?

Are you using some little hand held device? For a desktop type computer do as follows.

Go to
Vintage Tech Ref and Parts

go to page 2 half way down find

Vintage Husqvarna 1981 thru 1988 Tech Data and Husvarna Service Bulletin

save that file in a folder for future use.
go to pages 203 and 204 for the bike in the title.

I have contributed multiple times to threads about this subject. The answer for me is retarded from the spec enough so it hardly ever kicks back. about 12 degrees from top. It really isn't something that needs tampered with unless the rotor is removed. Might try putting your search terms in google and add cafe husky to the terms.

17 Degrees or between 2.2 and 2.4 mm BTDC

Andy.

Thank you Andy YOUR response is very helpful.

on the 400 and 430 i have been having good results going a bit milder from book spec, 1.5mm btdc on both and there is perhaps a small decrease in initial snap, the bikes pull a bit just as strong in the mid and upper ranges. both of these are running the old motoplat and the mellower timing pretty much eliminates any kick back as well. im sure its a bit easier on the engine overall.
not saying its the best way to set it up, just had good results with this past few years.

That is exactly the kind of information that I am looking for justintendo, the manual isn't always the best setup and I don't want any kickbacks!
Mine has the SEM (Sometimes Electricity's Made) ignition and since I have not yet run this bike, I thought was wise to check it, when I checked it with a dial indicator I was surprised to find that it is presently set at 22 degrees btdc, far too much advance. Given what I have read about kickback issues, my gut feeling was to set it at 2.0 mm btdc but wasn't sure.
The other thing that I wanted to clarify was that the 400 and 430 use the same timing, since I believe the US got 430's in 1988 and we got 400's in Australia, but logic tells me that they should be the same.
Both you and Andy have been a great help, it is appreciated. It's great to be able to access this information and personal experience without smart a&$e comments some feel the need to post, I guess it makes them feel superior or something.

i run 1.9 on mine and the difference is very minor but most importantly no kickbacks
since these are RARELY use for REAL competition, as in open motocross or cross country then why run the ragged edge
softens the starting, very little power difference and gas is not as critical, i use pump Chevron premium with no issues

Absolutely correct 2premo, both the bike and myself are well past our prime so why push either of us to the limit? This will be a Vinduro bike so no serious competition is planned.
I will happily forego a little performance for reliability.

I will ask you guys and this is a post from another site, maybe you guys can help this fella ?

I have a 1987 Husqvarna 430 with pvl ignition. The crank has a slot for a keyway, the flywheel does not. I can't figure out how to set the timing. If anybody knows please help.

Does it have any timing marks?

I'll try to find out, are you talking about timing marks on the flywheel or the ignition backing plate?

Why would the flywheel not have a woodruff key slot? Is there such a set up? Or does he have the proper flywheel?

The flywheel doesn't need a keyway, the taper is what holds it in place, the woodruff key is only to locate for assembly but does not allow the user to adjust timing on lots of bikes. I am not familiar with pvl ignitions but the rotor is timed to the stator at or before tdc.

So it should have timing marks for assembly and adjustability.

the pvl systems are known for not having a keyway, i believe its simply because they dont want to put one there. real PIA. yes, the key is only a setup tool but its nice to have. just a pain to broach a keyway so i guess pvl just skips it. should be some kind of marks for timing but like any other ignition you will still need a tdc dial indicator or a crank degree wheel. at least to verify whats going on with the pvl.

here are the instructions
the flywheel, if something that small counts, has a mark
the stator has 2 marks one for a clockwise and one for counterclockwise rotations, look for the marks
i had one and it was easy to time

I agree, and I think it was due to the number of bikes the pvl is adapted to fit that makes it near impossible to make a "one size fits all" ignition.

Thanks so much for the information guys. You guys are the experts and that's why I asked you all for the help. Much appreciated and thanks for the rapid responses.
