every time you kick your bike you have to use the comp release. the starting routine is not hard(even on a hill)

For $100, you can do the '03 450 cam mod, and make the compression release the completely unnecessary antique that it truly is.

The 450 exhaust cam is a must have for the 426. Read this for more info: http://www.thumperta...078#post3706078

I guess if you are just a total beastly stud you could just kick it over. But I weigh over 200lbs and can't budge my kick starter without using the compression release.
The bikes are really easy to start once you learn how.

I think i kicked mine over once w/o the release...
Stand on trailer well above bike. Then while yelling at your kids - jump down on the starter with all youre might. I think it even started because I dont think I had it in me to start the kicking again - my leg hurt! In fact I remember my lower leg hurting for a couple of days :bonk:

I may install that cam this winter with a valve check and such, I just bought my bike, 01 from a kid in North Jersey. It runs great but have been straightning out little stuff on it since :)

Enjoy

I have a 01 426 and think the whole compression release thing isn't that bad. I guess if I raced it could be a pain but for out playing on it I haven't been bothered by having to use the lever. I suppose if I have $100 I have to spend I would make the change but it works fine for now.

That's because you never had auto decompression. Kick starting is only a part of the story. The bike will bump restart like a 125 after a brake stall, if you have anything over 5 mph left, just by flicking the clutch.

I guess if you are just a total beastly stud you could just kick it over.

The kick starter might explode, too. :eek:

I have a 450 cam and a hotcam that were given to me when I bought the bike. Which one would you recommend using? I've heard differing opinions.

Based on the feedback I see here, I would use the YZ450 cam.

The Hot Cams exhaust cam is a slightly different grind, and is intended to be used with the HC intake. It works best that way. People have said that they tried the Hot Cams e-cam by itself, and didn't think it gave as good a result as the Yamaha cam did.

The YZ450 cam in an otherwise stock 426 gives a small overall power increase, but the real story is that it flattens and extends the power curve very noticeably. The sudden hit as you roll into the mid range is replaced by the kind of power you'd expect in a 454 Chevelle; if you can hear it, it's in the meat of the power band, that kind of thing. Much smoother, very beefy low and mid, with a linear transition to top end.

The OEM cam does require that you use a special procedure to time it. See the instructions in Common Threads.

What's nice for you is that you can actually try them both, and decide for yourself. If you do that, I'd say start with the Hot Cams, because I think you'll like the Yamaha cam better, and doing it that way will save time.

Remember that you'll most likely need to adjust the valve clearance for the different cam.
