    No. When I sit on it, it has the proper amount of play.

    Thought I'd bump the thread. Sadly, another riding season is winding down in the northern regions. We put about 2500+ miles on each of the 230's without drama. (we have two 230s) Both batteries failed this year which has nothing to do with Honda. Both were cheap chinese battery store models. They only lasted about 1 season. So much for the savings. We replaced them with Yuasa brand this time around. Both have developed rocker cover gasket leaks. Not too bad, oil is not dripping on the floor or blowing off onto other areas or clothing but still bad enough to need replacement. Since it happened to both of my '07's at the same time, you folks might be looking for it also. Can't comment on valve movement but I bet they're still in spec. since the bikes start and run perfect. I'll post my findings this winter when I check the clearance and replace the rocker gaskets. Keep riding your little red rockers! :D :freaky

    Honda doesn't use a gasket on the rocker box, they use sealant (Hondabond) I'm pretty sure resealing the rocker box would require engine removal...lack of clearance, the rocker box won't clear the cylinder studs before hitting the frame backbone. Are you certain the seepage isn't coming from the tappet cap O rings?

    No, I'm not sure of that. It's just a typical oily/dirty mess in that area. I did make a casual attempt though, and it looked like the source was lower/below the cap on the rear of the cylinder. It could leak down and pool there. When I get serious, I'll degrease and wash it good and have another look. maybe puff some baby powder up in there if its not obvious. Not happy about having to pull the engine if I'm right.

    First time I've seen this thread.

    I don't own a 230F but my g/f does, she's on her second, the first turned out to be knackered and was replaced by an '05 model once we'd secured a full refund from the supplying dealer of the first bike.

    Link to pics of the first bike, blocked oilway to the head:

    I've just fitted the current bike with the carb power-up kit and also made a rear subframe extension out of 15mm OD steel tube. I welded it in place along with two loops each side (6mm steel bar) through which the straps of a Kriega US10 pass through. The extension supports the weight of the Kriega and the rear light unit. We've also fitted a carbon bashplate and have still to fit carbon engine case protectors (both sides) courtesy of Chris Barnes here in the UK. His workmanship is very good with great prices.

    If anyone wants a pic of the subframe extension, let me know.

    BTW: the all white bike - looks great.

    Has anyone tried putting a CRF230L speedo drive on a 230F?

    I don't know for certain about the 230L speedo drive but I do know the XR650R speedo drive will work with the 230F hub. I don't see why the 230L speedo drive wont work...The 230F front hub has the tabs required for a speedometer drive, besides the speedometer drive (gear box) you'll also need the ~ RETAINER, GEAR BOX 44680-MA0-000 ~ number 8 on the 230L microfiche illustration with the front wheel. This retainer is what meshes the tabs on the front hub to the speedo gear box. You'll need the dust seal (40x50x5) 91258-410-013 as well.

    I had bought a set of 17" supermoto wheels that were laced to 150F/230F stock hubs. The guy I bought them from had an XR650R speedo gear box, retainer and seal on his 230F and he used an aftermarket speedometer and it all worked for him. If you compare the speedo drives, retainers, and dust seals on the XR650R and the 230L (both bikes equipped with 21" front wheels and speedometers from the factory) you can see the interchangeability.

    Thanks

    I didn't think to try one off a bigger bike. There's actually a 650R sitting in the garage next to the 230. After looking at some part#'s I saw that the product code for both the 230F hub and the 230L speedo drive is KCZ. That's the product code for an XR250S a dualsport/supermoto sold in Brazil I think. That's what made me think smaller bike.

    I've used Trailtech gauges on other bikes but have also had a couple fail, loosing the total mileage. The standard Baja Designs analog speedo is practically indestructible.

    +1 for the Trail Tech here. Mine is 5 yrs. old now and still working fine. I think for the price and ease of installation, they can't be beat.

    Can a CRF230F really make enough power to climb nearly 13,000 feet into the Colorado Rockies?

    Thanx. One of my biggest concerns about carbed, small bore bikes was power loss at Colorado altitudes. Wouldn't be much fun touring the Rockies if I'm constantly dodging faster traffic on every road. Are my concerns about carburetors at Co altitudes just from reading too much internet whining?

    You right. These playbikes will struggle climbing the Rockies. They will be holding up traffic. But they'll eventally get over the mountain passes. My Honda is not street legal; so I took my DR 200 instead to the Million Dollar Highway, and max speed on the DR was sometime only 25 MPH wide open throttle on 3rd gear (4/5 gears were useless). There was a long traffic jam behind me. :rofl:

    Next time, just pull over and let people pass. It's the right thing to do. :freaky

    No, jetting correctly for the elevation is a big concern for carb'd bikes here in Colorado. For whatever reason the stock jet was fine for my CRF230f, YMMV. :dunno

    The CRF230f is a great trail bike for Colorado. I would not recommend it for "touring" Colorado however.

    Just bought this 03 from a friend, probably less than 1000 miles. Mods so far, bars, hand guards, grips, home modified seat, U bolt peg widening, skid plate not shown, trials tire, opened air box with Uni filter, carb re jetted, cut the round end off the defusser in the pipe, geared 14/45, Baja light kit, spacers in the forks. Going out for a ride today.

    Great looking bike Tom, I have a plated '03 also.

    What is the back tire (and size) you're running on it?
