Im from the U.S.A and im having a very hard time getting anywhere with parts here. Can anyone tell me where to order a clutch cover gasket as well as any other replacement parts I may need in the future and maybe where to find a service manual. Im right in the middle of re-assembling a motor I just bought complete but it was tore down for inspection from the person I bought it from and I just want to be sure I get it back together properly. Even just some copy's of the engine assembly pages or something online that I could print off. Need help with this a.s.a.p!! Thanks _________________ Alex
Did you try the parts manual here at nsr-world?? It's really quite handy (now that the mc18 is up )
I've heard that you can get the part number and any good honda dealer will be able to order it, but they have to send it as a LIVE order, or something of the sorts. This was spoken about in more detail not to long ago.
i have asked for help here and inquired about used parts here as well, try TYGA i have an email into them gotta get parts somewhere? all you need is a gasket? there is a tech part of this place that will answere some questions. BUT it dont tell everything. and it dont sell parts either _________________ DAYTONA SPECIAL,74 RD350 LONG ROD, 2 RD200 ELECTRIC'S,88 NSR 250RG, MICRO SPRINT CAR W/CR 250 ENG
I dont know what model I have other than it is the wet clutch model. Is there a way to tell and is there really any differences in the bottom ends of the different years? I believe there are different cylinders but im not concerned with that since this project is going to use the cylinders off one of the rs250 engines I aquired anyway. I know some people have been kinda touchy when it came to my project and I hope I dont offend anyone here. People that dont like my project tell me im "stealing" parts from the nsr community. Anyway the project is a TRX250R drag quad with an rs250 motor installed but as you all know those dont have a kickstart and that just wont due for this project as pushstarting is not an option in the sand! LOL, so ive opted for the nsr250 motors instead. I have talked with tyga and they told me some parts from my 91 rs250 motors will interchange with these nsr motors like the cylinders. I planned on using the parts manual here to help me along in putting this motor back together but sometimes the manual explains certain things more specifically. We have a pretty good Honda dealer here, I will give them some part numbers and see if they can order them. Lastly what is a "Live order"? Thanks for the quick replies!! _________________ Alex
If you are struggling, then we can supply virtually any part you require. You may find however, that many RS250 parts are now discontinued, or at best, very difficult to source.
I'm not sure where you get the idea we think you are stealing parts from the NSR community, and I doubt you'll find people here that are touchy with what you are doing. On the contrary, I imagine most here will be more than interested to see and hear more about your project.
Have you tried to cross-reference your engine number with those in the Online Parts Manual yet? _________________ Andy.

I was actually just going over my cases and it seems I have an mc16. So am I right to assume all year bottom ends are the same other than the whole wet, dry deal? Anyway im finding the nsr bottom end is going to work out even better than I thought! I was having some trouble launching with my setup but the nsr tranny has much better gearing for what im doing and should work out great. That reminds me, we usually run an override tranny in our drag quads which allows us to up shift without use of the clutch or backing off the throttle but I doubt anyone has ever cut one for the nsr trannies so I was wondering if anyone has any input as to how well the electronic quick shifters work? Do they really allow you to upshift just like im talking about without actually having the trann cut? This is a very interesting project for me and some of the other die hard TRX 250R owners. If this works out as well as im hoping we will finally be able to compete with the banshee twins on the same turf. Well almost they are 350's but im looking into some other type of cylinders that will work with the nsr bottom ends and ive got some good choices although im not sure how well theyd work for you guys. Since they wont have powervalves which wont matter for me since we only run w.o.t. This setup will also be run on methanol so I will be really putting this motor to the test. LOL, there is also a lockup clutch system available for our TRX's and it should work on the nsr's as well with a modified clutch cover. Wow im really rambing on now but I will post a pic and hopefully its ok and if not im sure someone will erase it for me . Thanks _________________ Alex
Sure, of course we'd like to see the project, on one condition... if you want to post images of it, please keep them down to a sensible size, or post thumbnail links to full size images, so that dial-up users don't have a hard time accessing the pages!
Are you positive you have an MC16 bottom-end? ALL NSR engine numbers begin with "MC16E", so make sure before you jump to any conclusions. All the bottom-ends are different, but some parts are interchangeable - mostly transmission parts - athough care needs to be taken mixing dry clutch and wet clutch parts. All the NSRs share similar (not identical) crankcases however, so fitting is pretty universal with the correct mounting bushes. _________________ Andy.

All NSR engines start with the engine number of MC16E, even the 18s, 21s and the 28s.
Maybe it's just me, but that engine looks like it has a dry clutch?? _________________ Jerry Lai
NSR250 [MC21SP]
Im not positive of much but the full number on the case reads MC 16 E - 1219430. I cant even be sure that is right either as I got two extra sets of crankcases with the deal as well as a bunch of other spares! I will be sure to do more research if I find im missing something and need to buy something. I hope the pic is posted how you wanted? The pic I posted has the rs250 motor in it still as im still assembling the nsr motor. _________________ Alex
Im open to any other suggestions and info you guys have! How much could you get me a clutch cover and gasket for? Thanks for all your help! _________________ Alex
Wet clutch and there is no rush, I just want to be sure to have a spare incase I screw up this one when doing the lockup mod. You guys have any experience stroking these engines and if so how far can you go with or without trenching the cases? _________________ Alex

What size are the Banshee motors? What HP do they make?
Maybe you might want to consider a 300 conversion using the NSR150 barrels? There's no reason why you can't start at 70hp with a 300, and soon be knocking on the door of 80hp.
The RS barrels will work well, but they aren't a simple "bolt on" job. _________________ Andy.

Andy,
I heard the Banshee motors heavily tweaked in the 500cc bigbore versions are about 70hp (all peaky), so the NSR has similar potential with better midrange, longevity and durability.
Alex,
first of all, where are you at? I am in WA State and have an MC28 parts manual. Most all the '28 stuff is interchangeable with the '21 stuff if you know what you are doing. I can help with that. Also, about your tranny: under heavy modding/high horsepower, the NSR has been known to have weak 2nd gear. Of course, this is coming from the guys at HARC PRO, who know these bikes at their extreme racing limits that most street riders never see. It would be a real good idea for drag racing to have the gears back-cut. And running the wet clutch, you may notice that it will only hold well to about 60-65hp before she slips. May not be noticeable if running in the sand, though.
Stroking the NSR is not an option. Noone has come up with a rod source as the NSR rod big ends are very big for a 125cc cylinder.
You may be better off parting the RS engine out and buying the Tyga 300 kit. The RS stuff is getting really rare and may go for really good prices. _________________ Paul Herr
