Can't offer a comparison to the JD kit, but I have been running the Blais kit since my bike was new in 10'. Very pleased with it.

Does anybody know how the Blais kit differs from the JD kit? Just wondering if they have different jet sizes.

Probably the custom tapered needles in the JD kit.

I dont know the difference,but,the JD jet kit in my 530 works great,gets good mileage,fires up easily,warms up quick and off it goes.
Nice snappy power with no popping or problems.

Probably some jet kit installers dont take the time to dial things in,who ever jetted mine did good.

What kind of fuel mileage are you getting? I'm getting around 30 mpg with the JD kit. I'm not sure if that's good or bad...she really rips though.

If I can refrain from doing wheelies and broadsliding every minute or so I get mid 40's on mileage.
Its a hot rod,not a mileage machine.

To me its just a dirtbike with a plate, and that's how I tend to ride dirtbikes that make enough power to play with.
But it really doesnt do much worse then low 40's most all the time.

I need to put 1 size smaller pilot jet in as I have the fuel screw set on full lean,it runs so well as is I havent made time to mess with it.

The end of the muffler never has any black soot showing inside it so its not overly rich at most rpm ranges,it seems like most bigger 4 stroke singles my buddies own either pop or run kinda rich,who ever did the jets on mine got it pretty good,it runs about the same at higher altitude.

Average about 45 mpg all around riding with the jd kit. Never has been lower than that. Like Foot Dragger said, "its a dirtbike with a plate" so ride it like you stole it. Fuel + tires = $$$$=FUN= priceless

I had mine out in Nevada recently,I sat back and let it run up a slightly uphill sandy straight road...........I look down its going 90 and still pulling good. Jeechrise they really dont lack for pulling power!
Mine is jet kit only with Q muffler. 14/50 gearing.

I run some jetting specs I got from the KTM dealer in Santa Cruz CA. I think I am a little fat, but she runs real nice, starts easily, no issues. I got a big tank and don't do any epic out west rides, so I am content with it.

need some help here guys. My 08 450 xcrw just had a full rebuild and was running until some smoke appeared. My mechanic traced it the crank shaft seal, he installed a new one the same way as the old which is also the one that has failed. question is should the seal have the inner spring facing toward the bike or the clutch cover? just wanting to check because I know some seals came from factory backwards. the one seal was facing with spring part inside the engine so he installed a new one which failed so now I got another new one waiting to figure this out.

Spring faces the crank. I went to the 2009+ seal on my 08 after I replaced 2x, now no prob's. Some say it won't fit correctly but 60 hrs and works great, the 08 is pretty poor if you ask me the 09 is thicker.

So I have the bike back in my hands and got another issue. My mechanic said he did some research and found out that the crankcase breather hose is why oil is pushing back into my carb and to disconnect it. My dad and I have disconnected the hose from the crankcase and left the carb running to the top of the engine together with the t-joint blocked off. Now we have the hose from the crank blocked somewhat so that oil can get out because it keeps wanting to push out, is this normal? Is it because too much oil is in the engine?

shock spring help

I am ready to replace the rear shock spring and need a little guidance on what spring rate to go with. For reference I weigh-in at 190lbs, add riding gear that includes a camelback full of water adds another 15lbs and last are my wolfman saddle bags and tail bags with some tools and a few other essentials which puts another 20lbs for a total of 225lbs.
Is anybody weighing/carrying about the same load that could recommend a spring rate? I have looked at the race-tech site but their calculator only ask for rider weight without gear. Based on that it suggests going to the next heavier spring rate than stock.
Also does anyone have any opinions on straight rate vs. progressive springs? At 55 years old I'm no longer in race mode but do have those "moments" where twisting the throttle and acting like I'm 17 again do arise. I'm getting tired of having to straighten out my tag from bottoming out when the fun factor kicks in.
