DR650 FF Spotted on 84 and 90

I just want to give a shout out to a DR650 rider with a yellow ADV sticker on the back of his helmet cruising though CT and MA on interstate 84 and 90 last Sunday the 25th. Nice inverted fork set up! Kudos for riding in these temps, I guess I'm not the only one riding my DR on the highways this time of year.

That must have been me!
So funny you noticed. I turned a lot of heads that day.
I was on my way home to Boston from visiting family in NJ.
Does this bike look familiar?

kientech now also makes a mounting plate for the 'busa can which can be attached to their midpipe, and these are cheap. which means the gsxr can prices should come down, as they both seem to be pretty-much the same performance-wise and both need no re-packing. so, a used 'busa or gsxr can, and a kientech midpipe should cost no more than the fmf.

regarding performance, all i can say is when i got my bike, it had an open airbox, yosh can, stock header and stock carb adjusted to suit. it ran fine, but i only put ~100 miles on it before i installed the fcr39 carb, hi-flow midpipe, and tsukigi gsxr can. now, it really runs fine! but as i said, i don't really have much to compare to...

Steering head bearings

Good day all,
I just got my DR back from the local shop, they replaced the steering bearings. I try to go over and check nuts/bolts when they do work on my bike. The pinch nuts were super tight along with the axle bolt. I'm talking WAY tighter than spec. Steering feels a little stiff, but it could be from the new bearings? When up on the center stand, steering seems smooth. Any tips or tricks that might help me have some confidence that the bearings were installed correctly?
Also, I'm pretty much done with that shop.

Also, would anyone happen to know what size the nut is on top of the triple tree is?
Thanks

I will have the rack fabricated by a local welder guy, but it's always better to see what others have done before designing your own rack/accessories, as you can improve the design or simply borrow neat ideas.
So if anyone has built such a thing, or knows such a product, a few pictures would be more than welcome.
i built the rack, pannier mounts, & tool tube,

The old saying (If I remember it correctly) Power, light-weight, reliability; choose any two.
Always just two!

HP isn't really misleading...like I said; just math.

There has never been a 125cc two stroke bike that makes 40 ft-lbs of torque (that is why you have to twist their nuts to make them go!). A 125cc 2 stroke GP bike only made 55 hp at like 14K RPM which is only 20.6 ft lbs. I think KTM made the most HP in 125 dirt bikes= 37 HP @ 11K which is only 17ish ft-lbs. But, you are right in that the more rpm you have with a constant torque will always give more HP. That is why when building an engine a flat torque that doesn't fall off in higher rpm is more desirable.

Do you mean the pinch bolts on the fork tubes ... or the 4 pinch bolts at the front axle plate? NEITHER should be over torqued.

The Axle pinch bolts WILL SNAP OFF if over torqued. Lots of examples here. The Axle itself uses a high torque value ... not sure what it is but it's very tight. But NOT the 4 little clamp nuts ... be careful with those.

The Fork tube Pinch bolts on Upper and Lower triple clamps also should NOT be super tight? Why? Over tightening will Squash the delicate Alu fork tubes ... and ruin them. Follow Suzuki's torque numbers.

The Top Nut is 1 1/4" ... forgot MM equivalent. (inch and a quarter)

To test if steering head bearing tension are properly adjusted ... raise front of bike UP until front tire is clear. Try to keep bike more or less level.
Steering should go full left to full right easily and freely with NO drag.
You can also grab front wheel and pull on it and try to feel for any slack.

If steering is dragging, then Top Nut must come off and the adjuster below that needs to be carefully adjusted. Make sure the order of washers and adjuster nuts are all in correct order. Don't mix them up. You could also raise steering stem UP and check your shop put in enough grease. Don't over grease or over pack these bearings.

Good luck!

Skunkwizard - nicely done and very functional. Knowing your talents, you probably did that in your sleep.

Torque values - from memory - Axle: 47 lb ft "Pinch" bolts: 7 lb ft - My wrench doesn't go that low so I got an INCH lb one and do 84 in lbs.

Thanks fr the reply Grifter,
yes, the axle pinch nuts, the four nuts down by the axle, they were super tight. A lot more than the 5 ft lbs I tighten them. I've read about these being snapped off! And the axle(47 ft lbs I believe) was so tight, I couldn't loosen it without stepping on it and bouncing. And I'm a big guy.

It was pretty late when I got home last night, and I was a bit frustrated with the mounting of the wheel.......so, I'll check the rest this evening. Thanks again for the input.

I'll also pick up the correct wrench/socket for the top nut.

That stinks, dljocky. Did you go to Redline again? From my memory the upper and lower triple pinch bolts have different torque settings. You should check and re-tighten those to proper spec too. Sorry to hear about your shop visit. Freaks me out too when someone has been wrenching on my bike. An uneasy feeling about a bike is stressful.

go with the wide man rack and mount a tool tube on the underside of the rack.
i replaced my stock tool tube with a larger one.

I remember doing it last year myself, just like Adv Grifter mentionned with getting that pinch nut adjsuted it should never be over tighten and how stiff ur steering can be is uppon rider's desire. What u should do if u have time is to drop ur front end where u can see both bearing and look inside the frame to see if they replace the base of bearings (rounded metal o-ring conic shape-or bearing sets) they suppose to go under both bearings (lower/upper). Some lazy mechanics tend to disregard replacing bearing sets which render the use of bearings meaningless. In this pix it's on the top right (sitting over da bearing). There is special press u can buy cheap from Harbor Freight to get them out.
I thing the top nut of 3tree is 32 or 34mm. Good luck.

Dirtmonkey8,
No, I went to the other shop. Thanks for the information, I'm checking it all out tomorrow.

DR650SEDDY, I'm going to drop the front end like you suggested
