the 450 will have less power and will be harder to start, and will be heavier, but to make up for it it will require more maintenance.

Natural selection favors Smart people, so nature selects morons to be slow and dumb for tigers and stuff too eat. But in our modern world there just aren't enough tigers.

always cool to see new ideas but hopefully its more that a standard powervalve. had a kx500 and wasnt impressed. didnt think the RC valve was anything to write home about either.
Hey guys, heres the deal
Its bobs parts, done for him by Glen
We (Eric, Bob & I) didnt sit there and measure specs, compare it to other work, or try and scam information of Glens work.
Bob and I opened the box to check it out because he's hella pumped to freshen the topend of his bike. Eric met us at Bobs to go for supper so he checked it out too.
Bob cant tell you how it runs becasue its not installed yet, None of us can tell you the port timing or dimensions because its glens and we wouldnt blab it and didnt measure it.
Its not likely some open dune high compression ass-kicker race motor becasue Bob requested a trail freindly pump gas setup
All I can say from looking at it its that its deffinately a GSS worked cylinder and appears to be much like the other ones glen posts pictures of, yes it has the exhaust bridge, likely becasue its for "trail"
not sure if any you guys thought of this. not even sure how good it would work on the honda but i want to get a old cylinder to mess with and have the transfers open at different times. front one a few degrees sooner than the rear. seems to work good on the triple transfer motors. dont nobody go steelin my idea now
I like to compare workmanship, port maps, and idea's about anything in general about engines.
I think most motorheads are intruiged by these things.
Not that it matters anyway, because pictures and port maps don't give acurrate info about port trajectories and port radius, or volume anyway.
The face of the port is just the begining of the story, as most of the people on this thread already know.
I don't have time to or desire to cut my own jug again, never mind anyone else's.
I don't think an informed customer a scammer, its a wise customer!

let me guess, honda didnt do it so theres no way it could be good . have you tried it ? why wouldnt it work ? i like to believe you know what your talking about most the time but i often wonder . hey im not saying it would work for the better with a 500 cylinder but nothing ventured nothing gained.
seems to work here but what the hell does calvin know . brit/gss probly had their doors blown off by a few cub motors
ok thats what the secret was . crossed my mind a while ago but didnt have any extra cylinders to mess with so it was only a thought. good to see someone put it to action. hope it works good
i did it on a few, including my bridgeless cyl, was trying to save some fuel from chasing out the pipe. Didnt dyno it or do anything back to back so who knows what it accomplished, i'd like to think it was working. Havent done it on the last 3 engines, been working on other areas and leaving the port work stock size and location at the sleeve, too many different things at once makes it hard to tell whats what.
