apologies to the welsh contingent for the heading (it's what they say when they have a true friend BTW) but i did enjoy riding ady's and gruntenbergs 501 last weekend as well as fraser's 450.
a comparison to my wittle 400?
well i have a LX2 grunty lineaweaver cam
i've a ported 35/27 head that's now a 35/29. standard on all their bikes!
big headers (standard again!)
open end can which guessing from my dyno runs is worth 1-1.5 hp all the way through.
keihin carb is std on grunt's and cypher's machines.
except for initial whallop over a couple of yards my bike matched theirs. fraser's was the most dimilatr in nearly all facets. mine is so smooth and just revs annd revs making it just about as fast but weaker on torque. so i think i need to thank lineaweaver for that excellent cam again!
ady's old 501 vibrated heavily and the suspension was a bit ify. grunt's suspension was better but still the bike was low. i think he likes the heavy 48 front springs over his 44s as long as the valving is right. my bike sits 2-3" taller than ady's when hitting the bottom of ruts and my feet were always clear on mine.
fraser's bike was so similar to mine! very very revvy, suspension was very compliant, because my seals are gone and i've yet to 'beef up' the high speed valving, i had a lot more travel, enough to bottom out trail riding - so too soft for racing then!
BTW fraser, my bars are bent backwards by mistake but i can't be arsed to move them again!
one last note, because i never play with the hi/lo i don't know whether i had more torque sitting there waiting. i never seem to remember the bloody thing!
