125-200cc Woods project

Hi, cafehusky thanks for the already great amount of information here, been riding since I was 14 hooning around in the uk on my mates farm I've decided to get into enduro racing. Had a go on my exc 125 and placed 13th in a low class, thought it was great until I made an impulse buy of a 2013 husky 150 with 30 hours from new for £2000 and I realised how much i missed my first Wr 125! Problem is this CR 150 is a whole different breed! Never experienced the power this thing has! Wanting to turn it into a woods bike, thinking a flywheel weight and WR fuel tank should do it? Any advice would help. Thanks again, sorry for the long winded post

I take it you want to make the bike easier to use in the tighter going (woods bike) Firstly the keihin will need to be jetted perfectly and best of luck with that lol. The next thing I would do is to try and find some of Walts powervalve springs as they can shift the power around a fair bit making the on / off power smoother from bottom to top, Flywheel weight may help but I prefer the lighter rotor but Im a big fat old knacker and find the engine spoils up faster and pulls harder with the smaller cr item, But if you want to make it a real cracker of a woods bike Walts 165 kit is the way to go, Still after all the time Ive had mine it never gets the grin off my face no matter what bikes I ride I still love getting back on the 165 and if you went for a Lectron carb to finish the whole package off you would be one very happy camper, And lastly I dont like the forks on the crs as enduro forks but have never played with them to make them better on chop / roots ect but should imagine with a few adjustments should work fine depending on your speed and weight.

My wife and daughters pretty much learned to ride woods on a cr125. I had an Airstriker carb and a rekluse auto clutch in it. The rekluse really mellowed it out and made it rideable for them. I rode/raced a wr144 and did really well on it. This winter I'm converting their cr125 to my race bike. Switching it to the lectron off the other bike, keeping the auto clutch, adding a 165 kit and having the forks redone for the woods.I'm looking for more snap out of the corners and this thing has it . The ignition and flywheel brings it on the pipe hard and fast. I would add the auto clutch, then you can ride a gear high. You might try to soften up the front too, the bike is set up for mx, so it will deflect off everything and not soak it up. You could also look for a wr ignition and swap it. I'm sure there is a wr owner that would swap ignitions with you.

Two things that I would say are mandatory are an FMF pipe and a 51 or 52T rear sprocket. I wouldn't have thought one tooth would make that much difference, but it did.

I bought a used RB designs TMX and it also made a big difference. If/when you do a top end, measure the squish beforehand, and use the thinner base gasket to get it to 1 mm. All those things help bottom end power tremendously.
