I looked at your website and noticed you do alot of trail riding. I am just wondering what clutching you are running. I notice that most people run the 55g vs the 58g that I have in mine. HPD sent the 58g with the kit. What does the 58g do that the 55g will not. Is one better for trails than the other. Also what porting are you running? I also have red-yellow spring with violet secondarey. Cannot remember helix.

 

Snoopy61,

Wow, it's been a while since I've messed with the clutching on my machine, (if it works, don't mess with it) but I'll give it a shot. I know I'm running an HPD brown primary spring and a violet secondary spring. The weights I'm not sure of, but they did come with the HPD clutch kit I bought with my pipe. I do know that they are lighter than the stock weights. Probably around 51.5 grams. Between the lighter weights and the brown spring it does have a higher engagement, but once it's in the powerband it pulls like a freight train. But, it can still can putt around with the stock machines when going slow. The heavier weights would lower your engagement point assuming the springs were equal. I'm also running an Aaen Roller clutch with a 42-38 helix.

I had Rick Ritter from RCR give the Sport a mid-top end porting and it is worth every penny. The powerband is MUCH more noticable. To get the most out of a porting, you have to darn near have to have everything in place already. The reed valve, bigger carb, pipe w/silencer, and air box mods. The stock carb is a very serious limiting factor along with the reeds. Replace these first before you get into porting.

Hope this helps!

 

Thanks for the reply back. I do have everything and right now it is getting a new rod put in it. While it was down I was going to get it ported. What made you choose RCR over HPD? All I hear is HPD this and HPD that. I have noticed where alot of people are choosing RCR instead od HPD. Talked to the AZ bad boys and they too like RCR. How does your bike stand up against Banshees,Raptors and modded 400EX's?Where I ride there is a 300ft strip and I want to beat them. Most I alredy can it is the modded ones I have trouble with. What advantage do the lighter weights have over the heavier weights? I have a cool head also on pump gas so can I still run pump gas on the same porting you have? Thanks for the help

Ronnie,

I like dealing with Rick Ritter of RCR because he is a great guy. Besides, he uses Swaintech coated Wiseco pistons. I must admit to being the pioneer to the whole coated piston thing. Rick did a bore and hone job on my cylinder along with the porting. As soon as I got it back together, I babied it as I usually do for the first tank of gas. Then at Cochranton 2000 I seized the piston because I didn't let it warm up enough. Cold seizure is pretty common with the softer Wiseco pistons because the piston heats up faster than the cylinder walls. If you start the machine from dead cold and jump on it with out letting it warm up slowly, it will seize. The ceramic coated dome delays the piston's heat up. Plus the Poly-Moly side coating reduces the chance of scuffing. Scuffing is when the piston deposits aluminum on the cylinder walls and the aluminum jams the rings so you have no compression.

Yes, you can beat Raptors, Banshees, DS650s and 400EXs on just pump gas. At Cochranton I SMOKED a stock Banshee in a drag (this is how I seized the motor). He just wasn't even close. The modded machines might be a bit closer to you, but you should still beat them.

Lighter fly weights are better because they let the clutch engage in the meat of the powerband. The clutch should engage at a point when the machine is just starting to make more horsepower. The higher RPM engagement point assures this. Because there is less mass (weight) and usually a heavier spring, it takes more RPM to get the clutch to fully engage. Some guys (mostly the magazine writers), want the clutch to engage right off of idle. This is nice if you aren't interested in 300 ft drag times and want to crawl around rocks all day. But for drag racing and sporty performance, you have to have the clutch engage at higher RPMs (more specifically when the engine is making horsepower) to get faster times and more sporty performance.

C-Ya!

 

Mr. Chero, you seem to very smart when it comes to polaris quads.I have a 98sport 400L with rcr stage 1 top end kit. I run 270 main jet and have also installed v force delta 2 reed cage.I ride dunes alot and trails sometimes. I have hade the quad for almost 2months and have had the drive belt give out twice.I never ride in water becuase of the air box mod.Any suggestions on what is wrong. I am 6'5" and 270lbs, could i be to heavy?The second belt lasted only a few hrs at the dunes.

 

You are a time in the mods where you need to decide what to do. If you want to race 300 feet drags you should consider a full race setup.

If you want a fast reliable trail bike I would call rick and talk with him. Rick is also doing some race ports now to but I havent seen one run yet. HPD full race setup is fast to once you get it setup right, ask CED about the diff in speed once you get your combo right.

I have another company im dealing with but not sure how it is going to run yet so I have no comment on it yet.

There are other companys to look at to AZbadboys have been doing some intresting things to. Guess you can say im not sold on HPD part of it is I dont like running the same setup as everybody else, but thier race pipe is prob. the best on the market right now.

 

Sporty i got your pipe fixed.Ordered one last tuesday and got it thursday.This pipe hits and pulls really hard.I must agree it is probably the best pipe out there,for the race mod.It is probably the ugliest too.Later.

 

biggin,

Well, since you ride in sand the belt slipping due to water is out. There could be a few possible causes. The first could be that your clutches are out of alignment. Some how or another, the transmission may have shifted. Get a clutch alignment tool from Hot Seat or take it to a trusted dealer to have him check it out.

The second could be that the shims are missing from the driven (secondary) clutch. These shims are just two washers that fit on the secondary transmission shaft and are needed for proper alignment. Again, you'll need a clutch alignment tool to check it.

The third is that you're motor mounts are either shot or loose. When you rev the machine the motor will get out of shape due to the torque.

The fourth is that you may not have the belt cover sealed tight and you might be getting a little sand in there. Not that much that it will accumulate in the cover, but just enough to abrade the belt.

I seriously doubt it's due to your weight. I'm 6' 0" and weigh 250 and it doesn't bother mine, even in heavy mud. Granted, sand is a type of terrain that really saps power from your machine, but I still don't think that's it.

Hope this helped!

 

Mr.Chero
Thank you for the pointers!
