October 1, 200817 yr hi does anyone have any experience with the madrid motorcycle alpha bikes or their 301cc kit? if so, what differences have you felt, (sure, more power) but what about traction etc. cheers
October 2, 200817 yr Author I suppose this is for a 2T? yep, 2t, there's a bit of a write up on todotrial cheers
November 13, 200817 yr well, well, well, my alfa 301 kit arrived today, stay tuned...cheers Get someone to take pictures, of the crash!
November 14, 200817 yr Congrats, Borus... Are you aware that it's necessary to bore out the cases to fit the wider neck? Cheers, JM.
November 14, 200817 yr Author Congrats, Borus... Are you aware that it's necessary to bore out the cases to fit the wider neck? Cheers, JM. thanks jm, yes i was aware after deciphering the translation from aldolfo with my dealer, the kit is on, bike is up and running, after the run in we'll see how she goes, very very early feeling is it may have a broader power band cheers
November 14, 200817 yr Author i left the caby in it's 290 set up, fast throttle, 2.5 mm retarded, 45 pilot, 122 main, third clip in the keihin, it runs great, after a couple of hours on it riding my practice obstacles and sections the bike is what you would expect. more power, more low end grunt, maybe a wider power band, i thought third gear was very usable before, it certainly a fun gear now . obviously not run in yet but i'm happy to say it certainly accomplished what i was looking for. cheers
November 15, 200817 yr Author What was the total cost? 758 eruos including insured delivery to the door. i guess is have a slightly used 290 cylinder and piston available, i'm wondering out loud if someone wants to upgrade their 250? mmmm:rolleyes: cheer
November 15, 200817 yr Author Almost sure they are different bore and strokes on the 250 and 290. different bore, same stroke, simple swap out - (sherco's stoke numbers for the 250 is incorrect on their flyers.) cheers
November 15, 200817 yr Cheers Borus, just done the maths! Every year they print the same old figures don't they. So to downsize from a 290 to a 250 is it simply a barrel, head and piston change then.
November 15, 200817 yr Author Cheers Borus, just done the maths! Every year they print the same old figures don't they.So to downsize from a 290 to a 250 is it simply a barrel, head and piston change then. just did some checking and the 250/290 heads and crankcase set are different. so, will need to do some research on the swap cheers Edited November 15, 200817 yr by borus
November 15, 200817 yr So how much material must come out of the case? I would take a good 250 top if you find a trade!
