Wed, 20 April 2005 05:27 The one thing you didn't mention is if you are using a head with standard ports and cams. The limiting factor of a 2TG at this size is the ports and cams NOT the 40mm solexs. I can support this with personal experience and dyno sheets from three different 1940cc 2TGs. One engine I built for myself ran a 1940cc bottom end, standard ports, 286deg Wade cams and 40mm solex carbs with 34mm chokes. This engine made 92kw at the wheels but wasn't at all happy trying to rev past 6500rpm. I then had the head ported and ran 36mm chokes( the limit for a 40mm carb). The engine produced 97kw atw and happily reved to 7000rpm. My current engine is very similar but runs 45mm efi hardware throttles, a Haltech and 308deg cams. Its made a best of 104kw and is happy reving past 8000rpm. The point I suppose is if you are doing it on a budget then theres nothing wrong with using the solexs. I think the argument of parts availability is crap. Sure parts are almost impossible to find but who says you need them. My 36mm chokes were machined out from 34mm chokes. You don't need to change emulsion tubes and the like and as far as jets and air correctors go carefully soldering them and redrilling with jet drills is not difficult and very effective. you should only have to drill them out though cause you'll need to go bigger. Idle jets can also be drilled out to suit. Having done exactly this to two engines they were both very driveable and behaved as they should and performed very well.
