DR 650 engine sprocket - which way round please?

[Aslan]

thanks Fran - you'll gather I'm spending some dosh getting this DR good to go for things like the Dusty Butt when I look fwd to meeting you.

I'm off to test an MT21 front and D606 rear this evening on our PRAM track in a local forest.

cheers S

NZ spec is 41.
US Spec is 42.
The Freewind sprocket is 43

To be honest, my memory is pretty crap these days, like I'd probably forget my balls if I didn't have a bag to carry them around in, but I do know that I dropped 1 tooth. I thought it was 43 to 42 but it may have been 42 to 41. I will have a look when I get home tonight.

Edit:

I checked.
You are quite right - it was 42 to 41.

Flat side of the front sprocket to the outside (Just double checked on a new one up town).

Well, mine was new when I pulled the locking plate off and it was the other way, so there ya go. It matters not to me now as it's floating and so I guess the only way to find out is to do as Iain suggested and check the sprocket alignment (with a straight edge as I doubt the eyecrometer's accuracy).

Isn't consensus wonderful! Maybe north island bikes are different to south island bikes?
Just a thought, are the sprocket teeth central on the sprocket or offset as it may not matter which way the sprocket is fitted.....also, since no ones DR has blown up from sprocket mis-fitting yet, it probably doesn't matter what you do with them.

I'm with the souft islanders, flat side out. Then again though I was wearing out JT CS sprockets in about 2000kms with the scotty on. Suspect it was cause I could never get the amount of oil on the chain right through. I don't have a copy of the manual any more but I'm pretty sure there was a pic in there.

You need to grind the lip of the retainer plate to run a 14 tooth CS. Easy to do and no difference other than loose the cushion ring which has no real benefit anyway.

Doh - just re read the thread you already know about the grinding. Like TA - I was also running a 15/43 combo. Was a good compromise for the canty plains run and then river bed bashing/off roading etc. If we didnt do so much plains running I'd go for the 14/43 combo.

Why??? If you're running the same size CS all the time there is no benefit in the circlip. In fact there is a significant dis benefit in that the CS can move closer to the cases and potentially cause problems.

Ya can use overly large bright red words all you like but I dis-agree.

Self centering.

If you're not changing sprockets just loctite the screws up and you're away but if you're bored or like to fiddle the circlips make sense.

Self centering implying that it can and does more off centre sometimes...... I never lost a screw/bolt and I never loctited the bolts in the 12k kms I had the bike.

Well if you'd had it for a decent time

I havn't lost a bolt or used loctite on them either

But one side is being worn by the chain sideplate more than the other...

With the primative 5 speed box, whichever sprocket one chooses, one will never be completely satisfied useing just 1 cs sprocket! The 14t is indeed a good compromise, but compromise it is.

Color? Big and red:maybe gets the attention of those who miss the point.

It is however the old story: of leading a horse to water but the problem is making the bitch see sense!

You guys enjoy your circlipless system won't ya!

[Aslan]

hi fellow ADV enthusiasts - didn't intend my stupidity at not having taken greater care in noting which way a part came off would spark such passionate debate - thanks all for the helpful input - went through the Pram track here in Wellywood last evening (twilight run) without event with engine sprocket flat side out. Given I hadn't ground the plate as suggested by a number of you - I'll be checking for what damage if any i've inflicted.

BTW as Freewind points out this topic had previously been done to death - sorry I didn't search first.

As others have said - 'you've gotta love these DRs'

PS Off topic - if I had the wit and passion of NordieBoy I'd be tempted to try to run this thread on like his Newbie Post

PPS - Off topic - love the MT21 as a front tyre!

Last post on this topic from me - These bikes are a compromise in many ways and you have to learn to deal with that. To me this applies to every aspect of the bike including gearing. Tyres, suspension, seat, fuel range, gear ratios, etc will always be "wrong" but to me learning to deal with this is half the fun. Having the "perfect" bike for every situation is just damn expensive and means you'll still be annoyed at having the wrong bike for some of whatever ride you do.

As for circlips - I now have a 32mm socket for a 32mm nut

Cheers R

Very well said Ryan....this is just exactly why so many of us like them I guess!!

32mm socket eh? Well I can understand that no-one would want to carry this, and the 3/4 power bar for it, around to change sprockets at the side of the road!

14t c/s Aslan, and bolt the retainer on;either way round( apparantly!). Finished.
