Hi Hans, The biggest overbore I've done is 14mm on a Honda CJ250-out to 390cc (only did it cos I was told it was 'immpossible') I wouldnt worry about pin size...

Hey guys, I just found this place a couple of weeks ago and I thought I'd shared some good reading with you. ...
Hi Hans, I try to use used pistons for experiments so if it dont work its only cost me some time. If everything works OK I give it a couple of thousand miles...
I'm having a healthy little debate at the moment as to the cause of backfiring on a Fuel Injected bike ('02 gixxer 600 to be specific), in relation to the kill...
... hmmm, what about the thikness of the liner or the cylinder wall? What are the min measurements to not get in trouble here with a aircolled engine? Hens, ...
Hi both, I forgot to tell you I used the cylinder liners from the GS 1000, had the block bored to take them. It would be possible to go about another 2mm O.S....
Don't think of this stuff as the ANSWER to your questions. The ideas that he says that he "discovered" have been around the Tuning Benches for the last 40...
Hi, I read a bunch of stuff on the recommended site,(motoman?) a lot of it is based on research that was done by G.M. and Ford in the early 70's, plus of...
Fellows I am looking for some bright ideas about tuning the fuel delivery curves of a 2 stroke carburettor. It is an east german BVF fitted to the MZ250s .....
Hi Mike, I had some luck fitting Suzuki 2/s carbs to small honda foustroke motors. Instead of cutting down primary choke try drilling a hole in it. You can...
... in ... Interesting idea, might try that. What do you think about making the air duct smaller - will it make it richer at the top end, or just mess up the...
Mike, I'd be interested to know too. I've noticed that AMAL seem to use a "half-way" method, where there is an emulsion tube of sorts (for 4 stroke models),...
Hi Mike, I'll try and find out. There is a guy I work with that does weirder stuff than my but he only does big bikes ( he's building twin engine Kawasaki 1000...
Hi Mike, well I asked in work about modifying the air inlet tube, boy as this opened a can of worms! My view was that it would run richer everywhere because...
If you're talking about the air-flow fence on top of spraybar, that protrudes into the air upstream of the spraybar nozzle, lowering it will definitely make...

its cos primary choke carb (like two stroke) dont create a fuel emulsion (like 4 stroke), no emulsion tube. The air passage is there to stop inlet depression...
... All emulsifiers are intended to make the mixture leaner and moreso as air velocity rises in the throat at given throttle opening. That's primarily because...

Hi, I'm sorry to be working this to death but I need to get straight about fitting 2/s carbs to 4/s. At higher air speeds (ie full throttle) wont the air bleed...
... The whole reason for having a primary air bleed is to make it easier to get air density compensation in the carbie at the higher average intake velocities...
