what did a stock 600 suzuki around the year 2000 read on your dyno?

Never had a stock 600, but James Smiths (ex brenden Gere) was (from memory) 110 (this was a few years ago mind, so a bit foggy) one thing I always remember is a standard 1995 Rs 125 made 41, and a b kit made 43up, 1989 NX4 37hp

If you say had a 158cc single 4 stroke with a really nice plain bearing bottom end. Custom light forged piston. Redesigned port layout. An ingitech allowing 14000 to 15000 rpm. Flowed head that can pump 32hp worth of air. Massive titanium valve's and huge cams and a close ratio 6 speed in a good frame and a total bike weight of 82kg. That should go ok don't you think.

Thats what I want. Might be a bit loud.

all the 600 suzuki's on my dyno jet were 102-103 . l once dyno'ed a worn out one at 104.5 it was put on ray's dyno later that month and put out 115 hp on his !! . denis charlet tryed his bike on 3 dyno jets around the place and all were no more than a 1hp out to each other

Yea, I don't get too carried away with small differences, apples with apples and all that, but I am pretty sure a 6hundy set up for proddy racing 10 years ago was about 110

with a really nice plain bearing bottom end.

Why a plain bearing bottom end?

[TZ350]

Why a plain bearing bottom end?

A plain Brg can carry more load and rpm, notice rpm .....

Rich's posts are carrying a big hint about where things are already at and are going to with some of the FXR's that are on the front row of the grid ......

[richban]

Why a plain bearing bottom end?

Sounds cool. I know the KTM 250 dirt engine revs to 13000 all day with a normal bearing setup. Mr honda has gone plain bearing for the moto3 engine. Not sure what the others have done. There is plenty of power in the current engine setup its just up out of reach at the moment. Its all about chasing the weakest link.

Not sure at what rpm things get a little stupid on a single OHC 4 banger. 14500 sound like a good number.

And there is the key to what TeeZee is saying
150cc 4T at 14500 needs over 200psi bmep to go mid 30s crank power.
Full house intake and exhaust tuning, mega cams, tons of TDC overlap, and you think the 2T powerband is too narrow at 30Hp,try riding that FXR.
Sure Kev could make it happen, but I think the reliability cost and rider ability needed is out of reach to most.

[speedpro]

Pay attention , because there could be a clue here.

about how fast the 190cc bikes are??

[speedpro]

Nearly every recent post ignores the rider aspect. I'm not ever going to win a race again and if i recall correctly I have only ever won one in the past. Dave Manuell however is a totally different kettle of fish. Damned shame my bike stopped at Taupo. Rich is on to it though. If one of the fast young guys is put on a good 2-stroke it will immediately be in witha a chance whereas the exact same bike with me on it will be cruising around well away from the pointy end. Nathaniel being a good illustration of the point I'm making.

Agreed.

Chasing top end power does tend to turn your nice liner 4 stroke into a bit of a 2 stroke. I am sure there is a happy place. It's cost and compromise. And riding for sure. I am 3 hp down on my old engine but still doing the same lap times. Kart track that is. In the GP I couldn't even hold in a slip stream with Dave or Andrew A. Needs them ponies there for sure.

Yeah after seeing Dave M on Avalons 125 at HD he was my favorite for the GP. Also Avalon is super fast these days. I was thinking a fight between them for the win. Also if Gaz gets a few more HP he is a weapon for sure. Plenty of talent out there. Its great that F4 is attracting these great riders. North island short track series next year will be a cage fight.

That's 'cause your profile was considerably bigger than my wake.
