Mine goes in 90% before the reed stops contact the throat. They touch, but I wouldnt call it smashed down.

what if during the winter i drove up there, dynoed my bike, pulled it apart, got you to do your work then dyno it again?
whats it worth for a dyno pull?, or could you throw it in for free

i dont own the bike dyno, but have access to it.
that'd likely work.

got mine long time ago. could have been slight design change since then. your jug could be slightly different. hard to say. 1/4 way in they touched, all the way in the flapps were severly smashed. to be honest the damn thing almost needed a hammer to get it all the way in very first time i tried. something wasnt right. figured it was design flaw, they assured me it was supposed to be like that. whatever
. had to grind inside of the throat but they fit better now and reeds open more proper
also the insert didnt match the boot worth a shit. again they said it was fine
. took a fair amount of work to make the whole unit fit right. probly wont buy from mototassinari again unless they drastically improve the fit and finish of the products. funny thing is the cr250 had vforce3, fit like glove.

i'm sure Bobs and yours will be the same, the reed spacer i did for bob was an old rotten reed boot i milled the center out of to fit over the reedcage, i've used them before on stock reeds to sneak them back a bit.

I assume you may also do this to lessen the shrouding of the piston/ barrel inlet port and transfer boost ports by the reed unit?
That's the reason I run my reed block spacer - not for added case volume as it is normally used for. I run a 9mm thick spacer on my steelie - any more than that makes slide access too hard - on AFs I've been able to use thicker spacers, to get the optimal distance I want.

I'll see if he has any left. He went out of business and had some stock left over.

One thing I will say for anyone thinking about having Adam do porting for them... He has seen and tried out everyones porting, seen all the tricks the big names pull and has used all of this to develop porting I would consider to be equal to or greater than what you could get anywhere else. Plus hes a hoon though and through, so everyone go buy some porting from him!
Bob, you putting that on before dumont???

wonder if he seen this guys porting

hadnt seen that, but its neat, crank or wheel?
the torque peak is pretty dammn late coming in, and the same as what my conservative "twirp" porting does on the wheel.
i'm not going to say more HP cant be made, but it makes the bike a piece of crap to ride/own for most people

think that was at wheels. looks like a peaky hard to ride for sure

I am not aware of anything but wheel driven dyno's by dynojet.
I am sending my cylinder and cases to Adam this week.
I have 2 motors, and 3 cylinders for personal use.
The 3rd engine is being sold with my 450 chasis.
One will be for Ice racing, and so I am exploring other possible options for ultimate top end power.
Who's motor was that Clyde?
I am suprised to see numbers like that with a CR500 engine, and wonder if it wasn't on a quad, as the expansion chamber is the most restrictive high HP part on a bike from what I understand.

should be happy with roostious work. seems like his dyno was pretty good. not sure whole story on that engine. think it was a dude in cali did the porting and sent it to austrailia probly for a qaud. power curve is real steep. probly wouldnt be worth a shit except dunes

5 1/2 YEARS AGO!
I just popped off the head, and friggin' couldnt beleive my eyes...
I know some of you are going to chime in.... " Yea, but you dont ride everyday boB...."
I know, but I ride enough.
I need to get over to solidS, to give hime a hand forming his fuel tank. I'll post some photo's later....

Heres two before I go.... Notice cross hatch is still present, notice smooth bore, notice perfectly clean exhaust ports...
Good machine work ( Q&E in Anaheim, Torque plate & Plateau honed)
Good tuneup ( #42 pilot, DGJ Needle, #172 main <most the time>)
Good oil ('927)
Good airfilter ( UNI w/ Belray Sticky Blue !!)

Looks Good!!
Exhaust port is clean!
I need to pop off my intake as well and check it as I'm running a Wiseco for approx 3 years now.

I hear that '927 gummes everything up....
Only carbon found anywhere was stuck inside the exhaust flange, and it was minimal.

Yeah boy! 9 years on mine before the first rebuild. It didn't even need a top end then. I wore out the main bearings. No gunk, no scuffing, nada. Just toasted main bearings. The frame and chassis are pretty well thrashed though.
But then, I never ride, and when I do, I can't ride for shit.
