stroker crazy said:While there is a fad for extremely short pipes, a longer pipe works better overall.
People will follow fashion with short pipes and suffer mid-range power loss with (theoretical) stratospheric top-end revs, but some will prefer function over fad and go longer. Manufacturers usually have a reason behind the lengths they design for the bike.

JadusMotorcycleParts said:I rent a big space - its actually a converted laundry basement. Yeah, I had a really hard time finding a space too - especially in Malmö. Thats why I ended up in Arlöv haha. Nice you have a place now. Is your bike functional? It would be cool to meet up for a ride sometime
Eleganten said:Would be awesome to do some riding with another "small CC" bike!
JadusMotorcycleParts said:Definitely man! Get in touch when you get down here. Haha 'small CC'. Its all relative I guess. When my Dad was riding bikes, a 250 was a medium to big size bike, in many countries it still is. Something with the Swedes - they just love BIG bikes!
Eleganten said:Yeah, we swedes seem to have a fondness for big bikes. I've always loved smaller bikes. Maybe because I was brought up on an Enfield India 500 with 22 HP. I lived in Australia a couple of years back and worked at a wrecking yard/Yamaha dealer and I really got fond of the small L-plate bikes like the zxr250, cbr250 and the 400cc equivalents. We got shitty bikes here in Sweden due to old insurance rules but we do have really good rules regarding customization of bikes.
Do you know the measurements of the oil filter cover yet? Thought maybe Yamaha used the same for the sr4/500. In that case I have an idea to develop!
FerousBastard said:Wow you have been busy! That printer is definitely getting put to good use. Personally I'd go with the oil filter cover design to the far right but just as a cover without the height of the cooling fins, that thing looks rad! Just a thought; Any cooling ability of the added surface area of the other designs would be negligible to the effort put into machining the part. Adding ports for an external oil cooler, now that's a different story.
For the valve covers I'd do something similar to the rad looking filter cover. The engine casings themselves have a lot of fins going on on their own, flowing all over the place as you've pointed out.
You said you are in Malmö right? I'm in Kolding, Danmark and am working on redesigning a LS650 savage; http://www.dotheton.com/forum/index.php?topic=66958 still working out the details though, but could be cool to exchange ideas sometime.
zap2504 said:No idea of functionality (for that you would need to prototype and compare cylinder head temps) but I like the look of the horizontal valve covers! If the TT/XT exhaust valve covers fit the SR it might be a better manufacturing/sales plan to just make 1 exhaust cover and have a silicone plug for the SR use. As far as long fins vs short - if they were painted silver to match the engine, there would probably not be any visual difference between them, but (again) testing would tell if one was more effective than the other.
