Heh, I'll be passing on that.

Stagehand,
I've got an 8gig card in the thing. I tend to not run continuous shooting though. It makes things easier when I go to edit later on. As far as the HD squashing, it could just be that the video hasn't completely processed yet in youtube. I thought I had the same problem at first when I uploaded and only had 240. After a half hour or so, I had full 1080p.

I'm going to have to pick up a chest mount setup for mine. I like how it shows the abuse that gets taken when riding trails. Should make for some good video

Andrew

(at 6:09) I've said the same thing on SO many occasions!!

Oil cooler options

After lots of searching I seem to have found the basis of the oil cooler set-up used on the original G450RRs (Verhoeven's) as shown earlier in this thread



The Twin-Air oil cooler system uses an open 9-tube radiator and has fittings for nearly every standard manufacturer.... except of course the oddball beemer.



It appears that Verhoeven and crew used two of these systems in series, allowing for maximum oil cooling and capacity for the Dakar. Easy enough. The question now becomes how to best tie such a set-up into the 450 powerplant? The stock versions just replace the oil filter cover but the G450 might be more complicated - or not.

Could it really be that the only way to accomplish an oil cooler tie-in is the major modifications seen here in Bobby's (BMW Atlanta) pic?


Any insights out there on how to best accomplish this while keeping MAJOR modifications to the engine block to a minimum? If not, it would explain why Speedbrain chose to not go down this rabbit hole with their "production" G450RR offerings.

Ideas? Relevant experience?

Wild man,
Funny you should bring this up. I was actually about to design up an oil filter cover like the one in the picture. It should make tying in an oil cooler like the gold one in your picture there pretty simple. I had to do "R&D" on the shock mount pieces this weekend. All work and no play.....

Excellent! In that case, put me down for your first production model (or second prototype - I'm not picky)

My only concern was why they would tap into the motor as they did and not just come in through the oil filter cover - unless there's some issue about how it flows that wouldn't make it functional that way. I haven't studied the oil schematics enough to follow the "flow" and see what makes sense.

Regardless, I'm committed to solving the issue one way or another so count me in!

The shock mount looks interesting as well. I'll stay tuned for more "R&D" results from your "work" in the field.

Thanks Andrew.

4. Remove nut (large, left side) with pin wrench (Touratech tool).

5. Remove pivot shaft (axle) and taper roller bearing from right side.

6. Pull swing-arm to rear to remove.

7. Remove c/s sprocket (pinion) two (2) screws and lock washer.

8. Remove pinion.

Install - reverse steps.

1. Torque on pinion screws: 6 Nm

2. Move swing-arm into initial position.

3. Lubricate axle and taper roller bearing and install.

4. Tighten nut (pin wrench) 8 Nm. Make sure that correct tightening torque is applied. This is how bearing play is set.

5. Push the swing-arm to the left in the frame until it is seated against the spacing bushing. The spacing bushing moves as the swing-arm pivots.

6. Tighten 3 pinch bolts. Left: 38 Nm. Right (2x each side, alternately): 19 Nm

7. Use a grease gun to lubricate the inside of the pivot shaft (axle).

8. Install screw into left side of pivot shaft. 8 Nm.

9. Grease right side pivot shaft. Install screw. 8 Nm.

10. Install cap on right side.
Thanks a TON!

I'll keep posted for sure. I spend most of my time at work doing mold designs and not machining anymore. Which is nice, cause I enjoy machining, but for work it's not as fun. Making bike parts is far more exciting to me

I'll aim to tackle it this week, but might be looking more like next week. I've got a YZ to rebuild tonight. Oh the fun!

Andrew

ps. Oddly enough, the dealer had the missing brake part in stock. Now to just make my way out there this week too.

Haha- frickin stalling factor!... added to the fact that is a pretty steep slope- when it stalled I flailed like crazy on the downhill side, but decided it was better to eject than ride it down

Oh! Ithought you were talking about the get-off. SAme stalling factor, though

Adjustable rear ride height

Found a new swingarm with adjustable rear ride height.



Just go try it now

Cheers
Pilbara

PS: also found that with this new swingarm the rear ride height can be raised by 50mm and lowered by 30mm.

Sorry mate, have not heard or have any experience with this. I will be interested though as playing with shocks is on the to-do list.

Not at all. I do not regret it one bit. I decided to trailer to the trails, vs ride on the road for extended periods of time.
