Again, I can't join for this drive...
Those doing the Ulu Yam drive for the first time, I'd suggest you take it easy and enjoy the scenery along the way. There are some blind corners within the first few KMs and along the lake so be careful as there are the occasional oncoming traffic which eats into your lane! Had a few of these near misses on the bike.... scary shit.
Work on your lines and don't worry too much about speed lar. Eventually, everyone has to slow down at Ulu Yam town.... IIRC, got Sunday morning market there...
After the town going up to Awana, in the other car, I just usually stick it in manual and pretty much do the whole climb in 2nd gear (pretty much same for the bike). Never done it in the E38 before, but should be the same la.... just much slower. Again, work on the lines rather than the speed, would be my dua sen advise.
Same going downhill. Use a combi of engine braking and brakes. Unless u are using performance brakes, there is a small chance your brakes may fade towards the last few corners.... again, scary scary shit.... so just be mindful la, coz it usually the last few corners that you get really comfy with the pace and corners and tend to over extend...
Drive at your own pace and you'll enjoy it more!
