ahell Posted November 22, 2024 Author Report Share Posted November 22, 2024 First observation about the Mitani aluminum clutch. It perfectly releases the transmission when disengaging. The neutral selection is excellent even when cold and I can significantly lower the engine idle speed. Quote Link to comment Share on other sites More sharing options...

ahell Posted May 24 Author Report Share Posted May 24 (edited) I machined a keihin to 32.30mm to fit it into a remanufactured pipe. The original dellorto is 31mm. It fits without forcing. A quick dremel work to pop the pipe lug and remove the shoulder due to the original 26 diameter. I will test Josep Banyeres' sleeve to adapt the airbox. Otherwise I will install a TRS sleeve.

ahell Posted June 13 Author Report Share Posted June 13 Replacing the intake manifold to install the Keihin carburetor requires removing the engine. A screw is inaccessible... A quick stroke with the Dremel to adjust the manifold diameter to the white plastic part that fits into the reed valve. This gave me the opportunity to add an extra 0.5mm base gasket, following J. Banyeres' advice. The Italkit S3 piston and connecting rod are perfect. This was a good opportunity to check the previous work. 45/125 jets. It seems like a good base. New footpegs, more in line with Lampkin's bike. 48 idle jet (adaptable), 3/4 open air screw. I'll try a Keihin 48 jet to see if my adaptable jets are properly calibrated because I thought I'd see more difference between a 45 and a 48. I made three 3.5mm shims to shift the airbox further back because the carburetor and adapter piece assembly are longer than the Dellorto's. The engine is soft at the bottom. I didn't lighten the flywheel on this one. The extension seems better... test on the flat. We'll see on the climbs. 1 Quote Link to comment Share on other sites More sharing options...
