I have a stock port timing 500 with just bolt on items and the head cut correctly and I run a Skat Trak hooker 12 paddle at the Oregon coast with no problems. Best tire I have tried. Tracks good and straight, corners well and I would never have any less paddles and molded paddle again.

thanks for the help and I will keep all this in mind. 100HP, my head was cut a long time ago and I went tame at 14:1 on the comp ratio. I didn't cut it, I had a local guy do the work that specializes in large single cylinder 2 strokes. If I were going all out on the porting on this, I would have him...

#1. I won't do the actual porting myself, I would love to do the grinding but I'm too shaky to make it nice. #2. Unless this was a full out drag bike, I would never take the exhaust bridge out. I will put a degree wheel on it stock and see what the port timings are before any port mapping will be do...

100HP Honda, I just got done reading your post on the KTM 440 which has turned out real nice by the way and was looking at the port timings on the drag bike, okay I got to say my 192 on the exhaust duration looks tame compared to the 200 degree's on your drag bike. I thought I was pretty agressive a...

what suggestions do you have? Depending on the stock port timings which I'm sure are pretty low I wouldn't even begin to go this much on this motor. It's just a play around dune bike that I want to keep ridable and together.

Oh 100hp Honda you so funny!!! Maybe it was the secretary, I don't know. why don't you buy one and tell us what the power spread is like. My version of a clean up port will end up rasing and widening the ports a few mm's before it's over to match up the sleeve with the cast of the cylinder. I be a e...

ha interesting, I e-mailed them and asked if the 9 hp was actually factual since that's a huge increase just slapping a pipe on and if the porting was stock. They told me that the bike was completely stock so here we go I guess. I will probably do some clean up porting on mine but that's it. I asked...

I'm not made of money but for $299.00 unplated I might have to try one. They are a beast of a pipe from seeing the picture on their website.

has anyone tried the new CPI CR500 sand pipe yet? They claim 9 hp over stock pipe on a stock port motor. they produce and sell alot of banshee and snowmobile pipes and I know the banshee pipe is very popular.

okay that sounds good. What do you mean by exhaust face being wide? I assume you mean that the piston pin cutouts are narrow and just around the pin area so the exhaust port is fully closed and transfer flow doesn't escape out the exhaust?

Can anyone tell me if the piston pin height on the 84-89 CR pistons is the same as the 90-01? Sounds like either my main bearings or lower rod bearing are going out and it's time for a rebuild on my 93. I would like to use a Wossner piston but they only make a piston for a 84-89 which I find odd bec...

I would be more concerned with how trued each stock honda crank was vs it's weight since it appears from 89 to 01 cranks all weigh within grams of each other if it has the stock rod on it. The truer the crank meaning both wheels are aligned and equal on both sides, the smoother running the bike will...

I do the same as you do with the silicone this along with not overtightening the plastic cover seems to do the trick.

as crappy as the stock plastic stator cover is, it's about impossible to keep this area dry. This bike was pretty rough when it was purcahsed so who knows what kind of shape everything was in. Will ohm everything out and see were it stands. Rewind $100.00 Ricky Stator, if it's just the coil on the s...

bro in law's 500 was running great until he shut it off. Could not get the thing fired. Had weak if no spark. Typically the stator goes tits up if there isn't spark so I guess this could be kind of related to this thread. Will take the entire ignition off and check the ohms per factory specs but any...

has anyone tried VP's Q-16 oxygenated fuel yet? I was reading about it on a car drag racing site and it's sounds pretty impressive. Wouldn't be real practical in a general rider but for a dragger or hill climber that had to run gas, it appears to be pretty potent stuff.

1.8 is a good overall rod/stroke ratio but for good life out of a high winding 2 stroke motor 2 is ideal for piston and rod life. For our 500's even getting them reving to 8500 rpms and still making power 1.8 is fine. other than some sled rods I have seen, you don't get much stouter than a CR 500 ro...

if you trail ride, cast is fine and will last. I can tell you after having cast piston skirts explode into a million pieces, I would never run a cast piston. Dune only bike, forged all the way. As long as you get your cylinder bored correctly for a forged piston and you do the proper break in on the...

moose racing has the kind that has the loose stuff packed in a sheet that you just slide on. I just bought a 16" one for my PC silencer. This stuff is the best there is. Lasts for ever. I just got almost 2 years out of my last one and it wasn't that bad at that.

I have conversed a little with the sales manager for Wossner pistons USA. Nice guy. He says they will make any custom piston as long as you buy 4 like pistons. There manufacturing plant is in Germany where the pistons are made then shipped here to a warehouse in LA somewhere. He told me if I sent hi...

roller bearing, nice. Will have to keep that in mind.

when I bought the bike it had a gay aftermarket clutch lever and perch on it and it was broken. I put a new stock honda clutch perch and lever on it.

Danny, good to know on the spring deal. One thing of note, I did replace the rod as well because it was gouged at the end that it rides on the accuator. Maybe this cable thing is the problem. I will find out, I have a new cable and I will see it that's it. It's been on there since 1993 my guess so i...

in the 90-01 honda service manual in the clutch section on the first page in the parts diagram (picture of the assembly) it shows a picture of the clutch accuator, the part the the cable hooks to, with a return spring. There is a hole for one end of a spring to mount to. Does anyone have this spring...
