    A little help with an xr200r rear spring

    These ones (complete shock) are available in Australia and New Zealand new they are supposed to be OK, certainly cheaper than a genuine honda one out here at least https://www.ebay.com.au/itm/Replacement-Shock-Absorber-Honda-XR200R-1986-to-2002/273349478673?epid=12021337212&hash=item3fa4e60911:g:qS8AAOSwDn5bRXRx https://www.bits4bikes.co.nz/View-A-Product/Id/21328

    xr200 1980 flywheel removal

    So i am dismantling three xr200 motors two early 1990s, one 1980. Hoping with a few new parts/machining to end up with two good engines. The 1980 (casing number Me02e 5105889 = 1980 https://4-stroke.net/honda-vin-to-year-code-list.html) motor has a different flywheel stator setup which was updated in 1986. 86 on you can push the flywheel off with a 14x1.5 metric bolt. The 1980 flywheel thread size is different it's smaller anyone know the bolt size I would need? Tried a few I had lying around but no luck. Nothing leapt out when I googled it either, cheers in advance.

    XR200 year differences engine

    slight correction Honda changed the left crank half in 90 to a larger sprocket ID; early is 20mm, late is 22mm (also 86-87 TLR200). Early part number: 14311-107-000 Late part number: 14311-KJ2-300 actually everything up to and including 1988 is 14311-107-000 beyond is Late part number: 14311-KJ2-300

    XR200 year differences engine

    Thanks heaps Chuck that is really helpful the gear shift lever was welded on, on one of the engines I am working on and the countershaft on one is worn from ill-sized sprockets, plus I have a worn left side case this info will help ensure I get the right replacement 2nd hand /newparts

    XR200 year differences engine

    Just trying to compile a list of changes that occurred within the two valve engine over it's life (currently rebuilding 2 engines) So far I have the kickstart mechanism from old school Al The K/S shaft and lever changed in 87. 86 had a 6mm bolt, and 87 a 8mm bolt. The 87 shaft had a deeper groove for the larger bolt. Longer spring in 86 for ratchet. The gear change was 87......87 - 02 the large tooth type. The case was fly cut larger to accept the new larger dia spindle gear........can be done to earlier case. And from Chuck.... this gets a little confusing The left end of the kicker shaft fits into a boss on the left case, and the left case also changed part numbers in 94. So my summary is three kicker gears changed in 94 and both case part numbers also changed. But all three shafts have the same part numbers from 86 and on. The three bearings listed in the tranny part fiche have the same metric code numbers but the Honda part number for the right side main shaft changed from a Honda standards number to a Honda part number. A standard 6006 bearing is 13mm wide but my local bearing house did have a narrow version at 9mm, my 97 Honda bearing is 11mm wide. I have a 86 TLR200 case and that bearing is 13mm wide and the same Honda part number as the 86-93 XR200 bearings so it appear Honda went to a non standard bearing in 94. I seem to remember the bearing on the kickstart shaft became thinner to accommodate the wider gear, can anyone summarise the changes/years for the kickstart? Next there is the crank bearing change From Chuck Honda changed the fit of the right main bearing from press fit on crank and slip fit into the case, to slip on crank and press into case beginning with engine number 5705049 (beginning in 94) so you can not mix early and late right case, bearing, or crank. Unfortunately the numbers are on the left case and the fit issue is the right case. And there is the oil pump change again from Chuck The newer larger pump supercedes the small pump, has about 50% more capacity, the new pump was with the 94 engine but superceded all older pumps and then there is the lower camchain sprocket that goes on the crank Again from Chuck Honda changed the left crank half in 90 to a larger sprocket ID; early is 20mm, late is 22mm (also 86-87 TLR200). Early part number: 14311-107-000 Late part number: 14311-KJ2-300 Have I missed anything? I am working on a 90 and 95, I am getting a lot of parts from ebay and the freight to New Zealand is rough both need new rods and one has a pretty beat up left hand case so gotta be up to speed on this stuff as without care I could end up ordering the wrong parts, thanks in advance

    Mod or sell my XR200R

    I own both Xr250 and 200 the 250 has significantly more power but is significantly heavier. If you fall off in a situation where you need to heft the bike out of a deep rut or similar the 200 is way easier to deal with. The low seat height has it's benefits as it is real easy to stick a leg out to right yourself when things get wobbly. The 250 has much plusher suspension, and while everyone says xr drum brakes are ok, and they are if well maintained, disc brakes are great the decomp lever is nice when you flood the engine, and great for bump starts. It does feel like sitting on top of a tall building after riding a late model 200, it is quite a bit taller but you can get a rear lowering link to drop the seat height a little. I have a fork brace on the 250, it made a world of difference to the handling, in retrospect those long spindly forks just felt vague, I was having problems with random front end washouts prior to fitting the brace, could have been the tires or my (lack) of riding style but if I bought another 250 I would immediately stick a fork brace on it.

    XR200 rebuild question

    So I am splitting the cases on a 1990 xr200. So far for the top end I have new honda valves and springs and a motorcycle mechanic friend will rework the valve seats. I have a head with tidy journals good cam and rockers. I got a rktj cast piston for a good price and I am boring out to 66mm. New cam chain, guide/tensioner and sprockets. I have a proX rod on order and my friend will press the crank. I intend to replace all bearings and seals (bought a winderosa seal kit) in the bottom end and I will take a hard look at the oil pump and clutch basket and freshen up the clutch. What else is there in the bottom end or engine overall that needs close scrutiny, is subject to wear, that I will need to check thoroughly? I want to get this thing sorted to a state where I don't have any worries for a long time. Did a similar rebuild on a xr250 10 years ago and it has run faultlessly (with good maintenance and synth oil) ever since so I am a big believer in a thorough refresh.

    ‘96 xr200 build... sorta

    So Chuck I am confused, you had cr85 forks and you switched to crf150? or you you used crf150 forks in cr85 triple clamps? I thought most crf150's except the very latest ones had conventional forks (here in NZ I have never seen a crf150 with USDs?) and cr85's were USD? Reason I ask is I have xr250, stem, triple clamps and forks but they are old (87 pre cartridge). I was toying with the idea of putting them on my 200 and lowering the clamps a bit to loose some height but reading this and seeing LostIn207's very nice conversion makes me think USD CR85 forks might be the better option (there are plenty of dismantlers here that have cr85 parts) and I could use my stem on cr85 triple clamps. Would it press straight in or are more intensive mods required? Given both of you changed the top clamp is the Honda cr85 clamp less than ideal? Props to you both for these nice mods

    XR200 Piston choices

    Looking at a new Piston. Choices, aside from dodgy no name stuff, price wise they start with Namura, then proX then wiseco or wossner. Strangely I can get Wossner for cheaper out here in New Zealand than in the US and cheaper than Wiseco. Any of the last three would probably be ok with wiseco & wossner being forged. How are the Namura pistons for reliability/durability. Searching on here gives varied opinions has anyone had a problem in a small Honda 4stroke?

    82 XR200R Swingarm upgrade?

    lowering links are available for xr250's I wonder if one could be used to drop the seat down a little, they aren't cheap though

    xr190 anyone?

    These are being sold new in New Zealand for use as farm bikes, they are used as they are cheaper than ATV's on dairy and sheep farms. https://www.trademe.co.nz/motors/motorbikes/motorbikes/dirt-bikes/auction-1704795526.htm?rsqid=9e0141e49d1647ee9e06ca005c74e604 supercedes the ctx200 bushman https://www.trademe.co.nz/motors/motorbikes/motorbikes/dirt-bikes/auction-1544793586.htm?rsqid=101e97ff6a03463cbdc5523e9fcf9e14

    xr200head issues

    That post I think is this one (below). I contacted DRturnip who felt that his mod (which was done on a 125 head) might not cope with the increased torque/power applied to a 200 cam So you could buy one of those cheap cr230 style cams off ebay and fit an extension to it, at least to do a trial before wrecking a genuine 230 cam. What would be the best way to fit that extension, could you drill and tap the end of the cam and screw it in (or steel too hard), weld an extension on? I guess it would be hard to keep things concentric?

    xr200head issues

    Thanks Chuck can you provide any info on the dimensions or part number for the roller bearing? is it necessary to machine the end of the cam down to fit it?

    xr200head issues

    another one not sure if something like this could be done with a 200 (this was a 125)

    xr200head issues

    wow so I found this I messaged the guy to see how it worked out
