Thanks to this thread, I went and picked up the Collari XS12RTSGS5 at my LHS (I was very surprised that they had it!).
I haven't run it yet, and I probably won't until next week, but I am very impressed with the build quality. I have a couple of questions, though.
1. I noticed that the carb inlet is smaller than the Nova based carb on my Mugen MT-12. I am using a 15mm base Motorsaver filter on my MT-12, which I love. I accidentally bought a 10mm base 0.12 Motorsaver filter, which doesn't fit the Collari very well. After measuring the carb inlet with my calipers, I found it to be 11.75mm. Will an 11mm base Motorsaver filter fit, or will it be too small as well? If it's too small, what filters are you guys using?
2. I have heard of people installing tapered (without altering the fuel jet size) Nova carbs on Collari engines for an increase in power, at the expense of fuel economy. Do you guys think that would be an advantage on this engine (that would at least solve my filter decision!)? The stock Collari carb is already tapered, but its overall dimensions are smaller than the Nova carb. I was just thinking that a larger filter, coupled with a larger carb (tapered with same fuel jet) would allow the engine to breath much better. Any opinions?
3. Anyone interested in a 10mm base Motorsaver filter? I have a brand new one for sale!!
