XC / May GP Race

Thanks guys, I appreciate the comments The 'smaller' utility quad is an 800, not sure what the bigger one is. My only option is to pass them in the corners, there's no passing them on the straights. From now on I need to get ahead of them and stay ahead of them, lol.

XC / May GP Race

« on: May 23, 2014, 10:16:21 PM »

The track flooded again so there was only one race last weekend. I was a little disappointed that I was the only one in the Women's class, but I had a blast racing. Other than one guy trying to ride over me when I stalled it instead of going around like 12 other people did, it's the most fun racing I've had in long time.

For once I managed to kick it on the first try, but I still didn't get off the line that fast. I got a lot of practice passing, especially with the utility guys. Not sure what I can do to start any faster against the push buttons, although I've seen Kyle pull a hole shot on a dead start which was pretty awesome.

The video is the first 15 or so minutes of the race.

Great job, I wondered how that track was for quads. I thought about going down there sometime for practice (if they have one) to see what it's like.

Carburetor, Intake, and Exhaust / Cast Smart Carb has arrived!

Hey Breezy. Everything has still continued to run the same. The only issue I have had was a little bit ago. When I would be on the gas WFO pounding through the gears, it occasionally would bog. I had a suspicion to two what it was, but called up Corey at APT and asked him. He confirmed what I was thinking. He said that I was draining the fuel bowl and it wasn't filling fast enough. This was due to either needing more fuel level in the float bowl or the fuel cap was not letting enough air through the gas tank. He said that some of the aftermarket plastic check valve that you can buy for the gas tank are highly restrictive and don't allow much air in the tank. I happen to be running one of these. So, I replaced it will some regular black vent hose like factory and raised the fuel level in the carb. Not sure which one was the issue, but good to go now. Other than that, it has been running fantastic. I don't know what to do with myself not having to change jets and needle heights all the time trying to find what runs right! LOL. I have pretty much narrowed down the sweet spot on this low speed find adjustment knob on this Smart Carb and have not been messing with it much anymore. Hope this answers your question.

Thanks for the reply . I had one of those plastic vent things on my 86 when I bought it. I had seen a thread somewhere about it possibly being too restrictive and just put a piece of vent hose on it. That's great to know that it works well under racing conditions.

Thanks for all the info you have posted on the smart carb. I was wondering if it still seems to be a great as initially reported. I have seen threads on the billet carb ,but this is the first I have read about the cast carb. I have a 38 mm air striker on my woods quads, and it's a PITA to try to get the jetting right with the weather around here. I'm definitely thinking of getting the 38 mm cast carb at some point when the hubby gets some extra overtime. The jetting on my      Duncan MX motor doesn't seem to nearly as finicky (We never had to mess with the jetting like we do on the 38mm AS), but it has a regular 36 mm carb on it.

XC / First Races of the 2014 Season

« on: April 25, 2014, 05:23:02 PM »

Sounds like fun! It's about time you posted some of your racing info! I was beginning to think you had stopped racing. Sharp looking R.

Thanks I didn't race much last fall because the weather was so crappy, lol.
 
Hopefully by the next race my R will look a lot better. That plastic is completely uncut, but it was pretty scratched up and faded when I got it.  I've got new number plates coming from Cranked Up Gear, and my husband polished up one front fender with the boiled linseed oil/paint thinner combo, and it's working out really well. (I tried wet sanding the plastic, but that didn't really work out too well.)

XC / First Races of the 2014 Season

« on: April 25, 2014, 04:37:38 PM »

Last weekend was the first two races of the Fast Traxx Grand Prix Super Series. I finished 3rd on Saturday, and I was the only one in the Women's class on Sunday. Seeing as I haven't been on a quad since last fall I was pretty happy with how well I ran. Crazily I actually had an faster overall time on Sunday which doesn't make a lot of sense since all I had to do was get through scoring once to win.

I'm really excited because they changed the series this year. In the past the SX/MX/GP was all combined. This year the Grand Prix races are a separate series, and there are 16 races (8 weekends) where before there was only 10 or 12 races.

Engine and Bottom End / Finding a Pro X piston kit

« on: March 26, 2014, 04:10:31 PM »

How often do you recommend changing the piston?  I had Eric Gorr port my cylinder and bore it.  He sent the piston with it it is a 66.25 wiesco. It is on an 85 atc.

If your using a 66.25 piston and plan on using that size again you might want to try to pick one up on Ebay because no one makes them any more. It's annoying that these web sites show that they have them, then you call and find out they aren't available. Wiseco shows it being available  to order, but when I called the guy acted like I should have know they don't make them anymore.

If the bore looks good and measures within spec it should not need to be honed.  Anytime a cylinder is honed some material is removed from the bore, making the piston to cylinder wall clearance a little looser.  If your air filter does it's job and you run a lot of oil in the fuel it is not uncommon to be able to replace the piston many times without boring the cylinder.  If you hone the cylinder each time you replace the piston you will have to bore it more frequently.

Pistons need to be replaced frequently to keep the clearances tight.  Keeping the clearances tight makes the bore last much longer and the engine will produce more power.  Some of the seasoned racers understand this but the average guys lets the clearances get too loose and damages the bore requiring boring the cylinder to the next oversize each time the piston is replaced.

Thanks for the reply, I appreciate the information.  I bought this cylinder new from Duncan in 1996, and then they rebulit the whole motor a few years ago. I need to do a better job of keeping track of the hours on this rebuild. I didn't realize that it was down on power until I had my 86 rebuilt and had something to compare it to. I don't know enough about it to decide whether or not to replace the piston without it needing honed or bored. I should have just sent it back to Loren to begin with.

I am also curious as to how often it is recommended to change the piston. It's not like I get to go out and ride for hours and hours. I only race, and even then I don't put a lot of hours on my motors.

The guy who was going to hone the cylinder doesn't feel like he has the equipment or whatever to do it right, and no one makes a .25 over piston any more. I talked to Loren Duncan and I'm sending everything back to him and let him decide whether or not it needs bored.

I'll 2X on the ball hone idea. Most things have a place to be used, leave those ball hones to the auto industry.

So are you guys saying that you should never hone a cylinder, but bore it every time you change the piston and rings? Both the Honda mechanic and the guy in the shop at car quest said the cylinder looks great. They are going to hone it (with something other than a ball hone) and mic it and make sure everything is to spec before I order a piston. The guy at car quest recognized the quality of the work done to the cylinder and commented on it, he seemed to be very knowledgable.

It also seems to no one makes the .25 piston any more but Wiseco, this is according to the guy at LA Sleeve. So as long as the cylinder is true I'm either just going to have to replace the rings on the Pro X piston or make sure Wiseco has the .25 kit. There web site says they do, but they were already closed before I could call.

Thanks for the info guys. We took the cylinder and piston to the Honda shop and had the one mechanic look at it. He's been there for years and has a 250R. He checked it out, looked at the piston and rings, and measured everything,and he said it didn't need bored. The piston that came out of it is a Pro X .025. The mechanic said that it looked good and just needed a ball hone run through it. He said they don't do honing any more and they take it to a local Harley shop or Car Quest.

I originally bought the cylinder new in 96 when I bought the quad. It was freshened up once when I was racing back then. Here about 3 years ago I sent the whole motor to Duncan to be rebuilt, and I'm going to assume that Loren is the one that took it up to .25.

When I say overdue, I just mean that I haven't really ridden the 88 much since I got the 86 set up for the woods. I only raced the 88 once or twice last year and didn't notice it was down on compression and power until I had the 86 motor rebuilt. There's nothing wrong with it, per se. I'm freshening up the Duncan motor so I have the 88 as a back up for the GP series.

No that price is the norm. Loren bored my national ported cyl and found a woessner piston kit for it for the same price. I used to work at a cycle shop and a Wiseco was $49.99 so I really feel the prices are rediculous these days. I'm not familiar with the sizing any more, sorry I'm not any help

Maybe Duncan's not using Pro X pistons now, it's been 3 or 4 years since they rebuilt my 88 motor. The Honda shop could only get a .50 over Pro X piston. Somehow in owing a 250R for 18 years I've managed to never have to order a piston kit. I don't want to get something different without knowing for sure what I need. Hopefully Duncan will have the Pro X or something equivalent.

Ok, I thought it would be pretty strait forward to order a piston kit, but apparently not. I'm rebuilding the top end on my 88 because it's past due. I had my guy at the Honda shop check out the cylinder and piston, and he told me to replace it with the same .25 Pro X piston that's in it, however I can't seem to find one...

I'm gathering that the standard piston size is 66mm, is that correct? So I need a 66.25? The markings on the inside of the piston are CR25088, but even when I look for a piston for a CR 250 I'm not finding a 66.25. I've got to call Duncan Racing to order reeds and packing kit for my silencer but they aren't open again til Tuesday. They don't even have the piston kits listed now, it says to call for availability. I just looked the other day and it said they were $129.99 which seemed a little high.
