• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

DO I NEED A FLYWHEEL WEIGHT ON MY CR150 OR AM I JUST BEING A WUSS?????

I still think the bike just nees some fine tuning.

For ideas, here is what I have done to mine.
http://www.cafehusky.com/threads/one-strong-150.18103/

I am usually never happy with the way my bike runs but as it sits now I love it. It pulls hard and early but there is not much of what I would call a hit. I do stall it once or twice a ride now if I am doing real tech low speed stuff all day but it is not bad. It stalls no easier than every KTM 200 I have ridden, it is just not as almost impossible to stall as a WR. Speaking of a KTM200, a buddy of mine rode my bike and a 200 last ride and said mine had more low end and was better at climbing. So I am confident you can get a CR150 to work, especially for a fast guy which it sounds like you are. If you add FWW I would not go too big as then the motor will not want to spin up which is what I do not like about the WR.
 
Walt... TONIGHT!! I have to do some welding on the frame to fix up the broken motor mounts and i am putting the 144 on as well. Should i check the squish before i fire it off? Sorry for the hijack :)
 
Nice!

I will be there too, in Vet B. This will be my first Enduro...
Great! Good place for a first enduro! Hope you do good and have fun!
stalling is caused by rear brake application w/o the clutch fully in 99% or more of the time.

FWW WILL give you more [[traction]] for a given conditions. that's about it. and that's a good thing. the more grip there is the more traction you'll have.

if there aint no grip at all the FWW will help you get a little more drive but pilot input is still CRUCIAL. whiskey throttle = wheel spin at the wrong time no matter what.

a FWW WONT do jack diddly for stalling. you could have a frisbee sized FWW on there and the back wheel locking up would still kill the motor. once the back wheel stops spinning, the engine is DEAD- unles you got your finger on the trigger.

learn to stay off the back brake and use the left lever to mimmick a slipper clutch on decel and you'll never stall it again. i promise!

and have your finger on the trigger all the time where it belongs so you can mreeeeeeeeeeep! at a moments notice. your finger should be on the clutch 110% of the time, never ever off it, and it should be slipped 99% of the time both under accel and decel and why?

its a 125 (or 150 whatever) mreeeeeeeeeeeeeeeep!!!
All makes sense to me. But remember I'm a fast A guy. My finger is ALWAYS on the clutch lever and at work. It is a 150 yes. I use it on accel on decel. It is not really the problem with stalling that is driving me nuts, it is the hold on or die light switch that this engine acts like between 1/4 and 1/2 throttle. Jetting?? At this point I can ride my WR150 way faster. Not sure why. Lots of work this week and I should figure it out. Bought a flywheel anyways.

You are right. If my WR will work I'm sure with a little fine tuning the CR engine will be AWESOME! Thanks for the info!
 
Ben,
Yes, I would check your squish just to be sure. What base gasket are you going to try first? The .5mm will give you ~ 155 psi, .4mm ~165, and the .3mm ~175. I would try to hit about 95-96 octane for either of the last two. I think Mark is running av gas and his should be in about the 170 range. He likes his as you can tell from his earlier post. The extra octane will certainly help your bottom and smooth out the power band some. My high compression 144 top end with ~210 psi runs amazing with no real hit but solid power everywhere so throttle control is paramount. It has spit me off backwards a couple of times just wicking it on in 3rd to 4th below the power valve. Yours probably isn't going to have quite that response but pretty close.
Keep us informed,
Walt
 
185 PSI Had to fiddle with the o-rings to get it to seal up, then it gave me a good reading. How does 50/50 110 leaded sunoco purple mixed with 91 octane pump super? THis thing is going to RIP****************************************! BTW, i ran 2.5 gallons of 110 mixed with 1.5 gallons of super at a two day race this weekend. I ran a tank of normal super first, then switched to the 110 mix, bike ran better. Just seemed to be crisper and more responsive. Had a guy track me down in the pits and go on about how good the bike sounded on the track :) FLetchman, i know the race gas is spendy but it might be worth messing with. This was with a slightly advanced timing as well.
 
Ben,
50:50 will give you just a tad over 100 with those two. If you are going to use the 110 then go ahead and mix it with regular unleaded. Will still give you a 98 octane and save you a few bucks.

okidoki. just responding to the topic title.
i was an A (looooong time ago). now im a B+ maybe on a REALLY good day. :)

i actually prefer the 2-stroke MX bikes (CR's, RM's, YZ's) for enduro/off-road in rocks mud and alpine. love the MX hit and light weight. esp when picking it up and dragging it over ledges and stuff and esp when there's grip, and at altitude too (read power loss over 6000' and up). the front is just so light it clears everything (logs, ledges etc). i dont like trail-bike power or suspension.
if it got tight and nasty i'd go up a gear and lug it or slip the clutch. ya get better traction slipping the clutch with the engine spooled up and pulling a higher gear anyways so....

how heavy a FWW did you get? had 3 for my hard enduro CR's. if it was snotty i'd run the 14oz., rocks 11oz, hard pan 10oz. had a CO2 bottle in my box w/ an impact on a 24" hose and & could change weights in less than 5 mins (not the same ignition i know). i run the least weight possible while still getting that "pull".
a big ol honkin' FWW will kill some snap on some engines. so lemme know how it works. it might be just the right amount of relief yer lookin for. a little goes a long way. keep riding the CR, the hit wont be noticable after a while and will be there when ya need zap.

also- put a tad more play in yer rr brake pedal maybe?

my '09 WR125 aint got an true MX hit per say but it gives up little or nothing in a drag race or overall performance to my wingman's '07 YZ125 and his is stock sans pipe and pretty quick (Vet Pro). his has more snap and bark when free-revving it, more pop out of a corner- but my WR hooks up more. he's got a race pipe and muffler. my WR's stock with an FMF t-core sparky muff so it' quiet. if i ride it right we can bang bars and it's who gets tired first that loses. (i got 8 years on him so its nice when i win and eat on his dime hahaha) it's really a neat comapro. his is a full on YZ 125 MX bike going off-road (cept for the oem husky TC glide plate i zip-tied on his blue bike so it's had some case protection lol), mines a 125 WR. im as fast (or slow) on either.
 
My take on flywheel weights is that they don't get you more bottom end. They will keep the engine from stalling so easily in heavy braking situations and at extremely low RPMs where the compression can overcome the inertia of a light flywheel. What flywheel weights do best is keep wheel spin to a minimum and put more of the power to the ground once you are in the best part of the powerband. I have a flywheel weight on 3 bikes. It doesn't seem to affect the low end on my 250 MX bike at all, and seems to make the power rather soft on my 200 c.c.c enduro bike and 85 c.c. mini bike.
 
The diameter has some affect as well as the weight of the FFW. I put a short blocky 12oz. on my GasGas 200. It spools up a little smoother and stays spooled without bogging as easily. I really like it better after adding the weight. Just throw one on and see what you think but I bet you will like it.
 
nothing wrong with trying a flywheel weight. if your bike is hitting really hard you might check to make sure your powervalves are working.
