You definitely did not double your HP by adding a pipe, fuel tuner and airbox mod, I imagine several people have already mentioned this but I couldn't help but point it out. Stock HP is around 30, you probably added 3-4, if that, might be only 2.....
SO hows that 12 tooth sprocket going? Heard thata 12 tooth can eat the swing arm as well as stock. did you eventually go to 14 tooth sprocket? whats your rear sprocket size?
Thanks for the insight. I noticed that you live in California, if I'm correct? I want to modify my exhaust system. Where can I get the servo sub or something similar along with the fuel controller? Appreciate it.
Do you get noise with the flatland skid plate? That problem has been mentioned more than a few times in reviews and forums. I think it is caused by the motor vibrating against the plate at certain rpms. I guess the problem would be similar on trail or street riding. I am trying to decide on which skid plate to get. The Moose skid plate made of a plastic type resin is said to not have that problem, but I have to wonder if it provides as much protection as aluminum.
You could put a piece of pipe insulation type foam or some kinda high heat foam between the skid plate and engine, and that would most likely help that problem.
gbtayc . I have a flatlands skid plate on mine and had the same issue, big noise blowing back on you. Took it to the local body shop and had them spray the inside (side closest to the motor) with spray-on bedliner. Took all the noise away.
I like the mods, but that smaller sprocket on the front is a bad idea. Chain will hit swing arm if you do some serious offroad shit. Go up one in front, and then gear it how you want it with the rear. I'm not just talking shit here, I've owned 2 of these bikes.
The Wr250r has a weak spot, the chain eating through the rubber chain guides and into the swingarm at the front sprocket. Advrider has sick pics of this. A smaller front sprocket allegedly makes this problem worse.
Just a note. It isn't HP that gets your front wheel off the ground. That would be torque. Once torque gets you moving HP becomes more relevant as you gain speed. HP is what allows you to keep up with traffic on the freeway. Torque is what gives you the grunt to hop over logs and rocks.
From another post... Adding a tooth to the front does the opposite that adding a tooth to the back does. Larger sprocket at the front would decrease acceleration and increase top speed. Smaller sprocket at the front would increase acceleration and decrease top speed. Larger sprocket at the back would increase acceleration and decrease top speed. Smaller sprocket at the back would decrease acceleration and increase top speed. Take the front sprocket and divide it into the rear and that will give you the "gear" ratio. 35 / 10 = 3.5 The front sprocket turns 3.5 times every time the back turns once. Change the back sprocket to 40 and you get 4 to 1. For more acceleration you need a higher number. For more top speed lower.
@Nicholas King i doubt it. I've had my 02 wr250 for about 9 years now and it barely ever needs a thing these bikes are tanks. the only thing i've had to do it replace spark plugs, clean the air filter (obviously) and clean the carb after long sits. this one not having a carb (i believe its fuel injected but he doesn't have the year listed) probably makes it even more bullet proof
Hi Mrpeejer Going to buy the same bike just soon, and thinking on doing the same modification you have done, only question, do i need that Servo sub you got? or can i just have the same thats allready on?
if you leave the stock servo system for the exhaust you should be fine it just represents about 2% of the bikes weight at 7 pounds so it make sense to remove it. also makes for a cleaner look and makes it easier to work on the bike
I really wish they made a larger displacement version of these bikes. The dr650's and xr650's are ugly as sin. I would love a wr250r, klx250s, or even crf250l with a 450cc motor. Ktm 500 exc is like the only attractive large displacement option but they want $10k for them!!!
Nick Wayerski small bore engine turbos aren't very easy to tune. Let alone are they very efficient for the space and weight they use. Slapping in a 450cc would be a million times more productive.
heloy Mrpeejer i have a queshtion, i have a wr250r 2010,after i removed al the all the:AIS,flapper,exup... how to of the check lamp that works now? sorry for my english :) and thanks!!!
Should do suspension mods first. Will make your bike much faster. Also, Id pick up a new case saver that doesn't just build up with dirt like the stock. Cant wait till I get around to getting that whale tail off my wr. Got a bit of other mods before that since its more cosmetic that anything. Think Im going to go with the edge as well.
If you want a tire that will corner a little better offroad but still last on the street try the Michelin AC10, had one on my old street legal yz250 and now on my wr250f.
I just got a mint 07 WR 450 , bought it to have a heavy practice bike while I race the YZ125 and YZ250 . I have to say this WR corners better than the YZ ... The Cornering is Amazing . I dont really feel the weight until I have to correct or dab ... I wouldnt race it b/c of the weight but it is definitely a 100% off road capable bike that Corners fantastic ! The WR is the only 4 stroke ive ever liked and i've rode many. btw, I have an m59 and 404 on it , not plated either
I don't want to sound too harsh. I've had mine for two seasons and it has never left me stranded (except for a flat tire) The 6 speed trans is a big benefit for gravel roads. It is an issue with all dual sports. The more riding you do, the more skilled you get. Then you just outgrow the bike.
