Hi all,
I know already this is going to be a headache but i'm 50/50 on aesthetics and ride-ability on this thanks to www.wrenchmonkees.com in fact maybe 60/40. I have to give credit because it was what spurred me on to get an old twin to do up. In my view an essential part of the stripped down look i've fallen for is the unexpected space under the seat and so no matter what the cost i have to have pods. So i'll have to learn something or another.
From what i've read CV carbs like the Mikunis on my GS are not happy with pods due to a lack of flow resistance/vacuum on the filter side, are not fully adjustable and availability of jets is a problem. So i noticed a lot of customs have Keihin CR specials on but read enough to see they are really only good for a lot of flat out racing, they look cool but i want something more street suitable. Then i noticed chat that Mikuni VMs are more suitable, cheaper and available, as are jets for them.
Am i getting this right so far?
I'll be getting some more open pipes on as well and so i'm wondering if i'm going to get other carbs with more open filters and more open pipes i really should just flow the ports while i'm at it (handy DIY guide http://www.pirate4x4.com/tech/billav...0Abrasives.pdf )...... just so i can use K&Ns
As you can see i've gone completely insane
before you say get a bigger bike instead of trying to tune a small one i did think of it but i really want a thin light nibble thing to chuck around town and the tight country lanes here, and this really is an exercise in aesthetics.
I'd rather tune for low and middle grunt than top end so again from what i've read i probably don't want a very big bore carb which would give better top end. But how do i work out what i should try? How do i know what size/type carb to get without something to try first to get an idea and go from there.
Please help untangle this if you can
