    The R18 sidecar thread

    Hhhhót out here today. Over 30 C. before 09.00. Now at a venta for coffee and water. Have the backpack loaded with metal cased laptop and tortoise green harvesting stuff. Pretty hard core on the bicycle but operacion bikini rules. What that has to do with the threas subject? Simple. I also...

    R18 Louvered Performance Plates

    The simplest would be enlarging the top opening. Now thát would imo need a mesh to discourage rodents to overwinter up there. For the rest it would not do much harm to do away with the filter entirely unless you plan do cross the Sahara or go do rally raids. Normal road use sees not much dirt...

    Two up ?

    'not quite right' is not a very precise symptom ;) Start with setting the preload to nigh max. Also check and maintain the tyre pressure religiously. Next cruise, not race. Although the bike tracks véry well, it is not a sporty one. Before I fitted a sidecar, I have done more kms two up...

    The R18 sidecar thread

    There are quite a few ant species that protect the plant they live on. I am sure NorthAmeria has a fair share. The region here is NÓTHING like Cataluña. Also the southern mountain range is not just a climate and water divide, it also is a tourist devide :ROFLMAO: On my morning cycling visit...

    The R18 sidecar thread

    Went for a short spin. By the time I had the chores done, it was too hot go cycling so... sidecar! After some nice rolling trough the 🤩 countryside here, took a detour to the industrial estate a bit up the road. Is about deserted on a Sunday and under the mid day sun the odd sole stays inside...

    R18 Louvered Performance Plates

    To the dust/critter fobic: Before the roads grew a black hard top motorbikes used to have nó air filter or at best a course gauze. The Nimbus type C has a véry rudimentary gauze pad one yet several go round the word trips over unmetalled tracks. Dust intake not being a worry. First hand info...

    Thanks. Confirms the lower range of my accelerometer results. Seriously I réally appreciate this. Nothing new for mé as both the science and engineering of the idea are sound but it still is another hard confirmation. About 2 strokes I nowadays limit myself to tuning not so modern Vespas by...

    The R18 sidecar thread

    Today a classic vehicle event further up, east, in the mountains. Only 65 kms but over local road just on the north face of the range, staying between 650 and 850 m altitude and áll twisties. As the road is simply modern surface on an áncient route the twist and turns predate motorized vehicle...

    1. you are mistaken 2. at the top where the engine mounting and cables enter, the hole is open. Right and that was ít for me; wishing you success.

    For a try simply leave the plates off and also the filter lid. The filter will stay put; don't worry about that.

    on the R18 it would be fixing a non problem, introducing turbulence, instability and less flow to the oil cooler.

    R18 Louvered Performance Plates

    there is no doubt that a sump guard would see less cooling air flowing. 'Detrimental' though implores negative effects and I as the engine runs quite cool I cannot see thát extend. It has a plastic sump which does not radiate as much as aluminium and has the oil cooler. So yes, a wee bit less...

    R18 Louvered Performance Plates

    Actually they don´t. At least not pushed in. Behind the fork / front wheel and mudguard is a lower pressure area with turbulence to boot. On the move no hot air will be sucked through the side openings. Yes @Gr8adv I had noticed the covers staying cooler too. Speaking of cool I am amázed at...

    The R18 sidecar thread

    Meanwhile, on the parallel slow fire... Still had the desire fot a solo bike. Lighter than the R18 but retro and a lot lighter. Enter the R45. I already háve two solo bikes though; Vespas more suited to the local roads than an R45. A dear lady friend convinced me. Exit the R45. Back to the...

    R18 Louvered Performance Plates

    Have a look at the top of the casings. It is where dust and whatnot gets in anyhow. The dirty the harmonicas where on the OUTside when I deleted them spoke clearly to me: It is an intake. As I have observed several times; this opening si why the engineers added opening to the filter lid; to make...

    R18 Louvered Performance Plates

    The obvious (or not so 🫣 ) way: Take a harmonica wubbah a draw the circumference of the entry side on paper. Calculate the surface. Time 2 = the intake area. Whatever one does to filter, filter box lid, this is where the air enters through. Have some fun with none too complicated...

    they do, Use the wind tunnel even. Just different models and also different riders.

    Important Turbulent free riding

    Indirectly; the trail is 150 mm. The rake is btw the culprit for the tricky front braking at coming at a stop.
