Well 1,600 miles and so far all good.
1.) I am still hedging on the best storage, love the look of the v46 on these bikes size wise but am torn for the storage of the E55.
2.) I am leaning more away from 20x12 14GR DR Pulley slider rollers and more towards maybe eventually Dr Pulley 20x12 16GR when they need replacing.
3.) K&N doesn't have an air filter, Ligh Tech does have a washable one for the DT 300i 2009. I guess it is the same, so if K&N doesn't com up with one soon my order may have to come from out of the US.
4.) Still no oil loss yet, but time will tell. So far I am happy with the performance with the bike power and MPG wise.
5.) the muffler stays, I don't need the minimal performance increase to justify the extra amount of noise.
6.) HIDs are on hold. I don't want to use the extra 2 bulbs on high beams (because of bulb warmup if the lows turn off). I know it is only 70 watts or 1/10 a HP but on these low power, high MPG, machines that could make a difference. For now I am going to try 4x H8 PIAA Extra Super White 35w=70w bulbs. Worst case they go to my Sonata fog lights later on.
