Glen if I moved posts about, to un-highjack threads.... thats all I would do all day!!!glen howell wrote:Bob, I didn't mean to high jack this thread ,Would you please move my post about the 720 to my question and answer stickey.
We are running a 350 single on the dyno right now with a aerocharger 53 series. The turbo is a bit too big for that motor. 500 should be able to get close to 8 to 10 PSI?. Here is the funny part, just looking at peak hp numbers, NA this 350 snowmobile motor makes 64 hp and we hold it for 5-8 seconds on a pull. It is stock, no mods other than a larger carb.2strokeforever wrote:highjack away it dont bother me at all, nice work glen, whats a mild port job and head reshaping worth???,
or roosty do you have more info on your porting, not specs, but dyno sheets if the low end is that much better i might be interested but it have to be a big improvement for me to go with a low mid powerband...
glen I got an idea for a guy like you, its expensive though, aerocharge a 500![]()

it builds boost at high idle WITH NO LOAD, and dosent restrict flow on the top end, and it dosent need oil
you would be smoking R1 climbers on a 500 that weighs half as much![]()
only downside is $2500
You would think S/H would do alot of things differently....2strokeforever wrote:youd think aj would put a needle that works in the bikes he sells
is your service honda built with a newly assembled engine or did you provide a engine if its new are you getting any assistance with problems the clutch problem is bullshit and why didnt you get some spare jets from them lot of money just for a bike2strokeforever wrote:I went riding on some big hills and got the jeting better, wow the 500 can shift up on big hills where a 250 needs to shift down, and my bike is geared way higherright now im happy with the power and i know the 250s i draged were only close because there was no traction ( HARD gravel road )
please explain, the only way i can adjust from where i am without the clutch slipping is looser which would make my problem even worseand the reason its not disengaging is because your adjustment is wrong on your clutch cable
the only thing that bugs me is the stupid clutchcan anyone tell me if this is a 500 thing or new bike thing...
I just figured out that I acidently put energy conserving oil in the tranny
thats why you shouldnt work on a bike after a 22 hour day. aparently it can cause the clutch to slip ( it wasnt slipping) im changing it before i ride it again , but i still dont think that is causing my problem, i want to have it fixed before i ride next weekend
THE CLUTCH DOES NOT FULLY DISENGAGE even with the lever pushed to the bars i need to have it adjusted with less (5mm) than the recomended minimum free play (10-20mm) otherwise i cant even shift properly, normaly i use 20mm but i need all the travel i can get
how far should the blue be able to get it geting prety farhow long do i have to hold my bike wide open up a steep hill to get a acurate main jet plug test 10, 20, 30 sec? could it be my rich pilot is making a lean main read tan because it takes a bit to burn the black junk off
im a 1200 ish feet 170 main 42 pilot airscrew 2 turns out CCJ needle 2nd from the top
is this way off or does it sound about right

just before I bought the 500 I looked at last years KTM300 and after everything was said and done they wanted $11 000![]()
![]()
I got a carbon fiber skid plate and the spark arrestor thats it, but the $12.5k is after exchange, bad weather shipping fee, tax and shipping so it worked out to $1.5k more than the KTM , and i didnt ask for any jets I assumed it would be close![]()
for you asmericans you could get it for $10 500 and it seems easier to get around taxes there, but then a crf 250 is probably only worth $6000 down there
I got the jetting better, tan plug after wot plug check, the pipe turned blue till halfway thru the second bend, still a little rich at low throttle...
it handles great, killer low to mid, the HPSD seems to work it dosent stop headshake but it makes it really weak, the bar ends only move a inch or 2 if you get it![]()
the things I think could be better:
the clutch dosent fully disengage if you use 2 fingers, adjusted with minimal possible lever free play, makes it really hard to go thru tight trails because when i use 2 fingers for the clutch the bike will stall unless i give it gas and it still tries to creep forward, so i have to use 4 fingers but then i cant pop the clutch to get over a 2ft log because the clutch hand isnt holding on well enough![]()
is that normal for a new bike, or 500 or do you think it was assembled wrong????
the gyro effect I can really feel it, especially after coming off a 125, does 250 flywheel + ignition help this?
when I draged my friends on 250 they would stay right beside me until 4th gear (im a better rider than them), is that normal, or could it be that being on a gravel road made me spin so much that traction was the limit on how fast i could acelerate and more power would just mean I roosted more? I will try on asphalt as soon as i can
it would be nice to have better top end I got 1 days riding worth and I already want more. tan plug after wot plug check, the pipe turned blue till halfway thru the second bend so i know its not rich at wot
is there any way to get more top end power without losing much low end torque or mileage via porting
WHAT IS WITH THE BIKE COUGHING WHEN I DONT KICK IT HARD ENOUGH?????? if it dosent start a quarter of the time it will cough, its not backfiring because my foot dosent feel it when it coughs its just a pop/ phut sound coming out the exaust
heres what i am thinking of getting when i get $$$ anyone do this and what did you notice:
clean up casting flaws,polish exaust port, jet it as close as possible and a 250 ignition... 00 or newer
anyone have a 04 or newer ignition I rode a 04 cr250 and i could feel the traction control compared to a 05 kx and yz 250, i think honda was on to something it worked great(note the TC does not mean you dont spin but it somehow puts power to the ground better than anything else ive rode even with a bald tire)
what is required to make the 04 + ignitions work?
I'll second that. I run a 175 main at 3000 ft. at 32:1 and it's not even close to being too rich.kdizzle wrote:My specs again:

i have no idea how the hell you guys get away with such lean jetting. If i run anything less than a 55 pilot my bike wont start for shit, and is so ring dingy that it wont rev down in the air during a jump. I run a 60 in the thing and like it.
I run a 182 main in the cooler weather and believe it needs to be leaned out now that the hotter months have come around but I wont go any leaner than a mid 170 or it will ping its ass off.
My needle is a DGG and is right in the middle clip.
My bike pulls cleanly and has no spooge. Other 500 riders comment on how well it runs and a couple folks who have good running 2 smokes comment that my jetting is pretty damm good. it doesn not stop pulling until it hits the rev limiter.
I Ride with another member here who has a 41 and stock 86 motor, same premix and runs very close to my settings. He does have a slightly leaner needle though (CGK)
Maybe it is because I am flogging the bike on the MX track. I dont claim to use everything the 500 has to offer but i do twist up the throttle a bit. I run a PC pipe and use the upper rpm band. In WORCS races I run B class or intermediate class on the local races.
I know the P&P will open up the bike for more fuel but you guys are talking 45's for a pilot, which wont work for me at all.
baffles me every time i read these posts.
i know, havent looked yet but i put a new one in my 125 and it was notched real fast so mine is prolly toast, but if i dont look i can fix it laterYour SH was brand new right? Look at the basket and hub now and you will shit your pants...
what else fits the barnnett basket, can i get a complete barnet 250 clutch and swap plates to oem and swap the ring gear and will it work????Don't do OEM for the hub
