Hey guys. I am totally new to this forum and to the world of motorcycles (well I've ridden them but never worked on them). I have seen a few similar problems in other threads however I am what you could call mechanical un-inclined. So basically I could understand most of the reply's. So if anyone has a ultra baby step solution to this problem I would be greatly appreciative. Okay so here's the deal. I just bought (yesterday) a 1997 Suzuki DR200 that I planned on using as a get around town and exploring bike as a pretty beginner rider. When I bought it it ran great. When I got it home yesterday it ran just fine. When I tried to start it this morning it wouldn't go. It was turning over but not firing. So I pushed it down the street to a friends house who is pretty good with bikes. I live on a hill so on the way down I was able to bump start it and it ran perfect until I got to his driveway and stopped then it stalled. So we took the Carb off and cleaned the jets and put it back on and it started right up. I took if down the road and back and noticed it idled to low so it would stall if you didn't give it throttle. We turned the idle up but then it was so high that it would basically keep going in second gear with no throttle added. So we turned it back down but once again it died. This time it would not start and we killed the battery. We tried several times to bump start it with no positive results. So we pushed it up the hill and on the fourth try it worked and proceeded to bump start every time after than. But the problem still remained. We drove around and got the battery back to where we could start it with the electric start but it still wouldn't idle. And now it seems like it takes forever to come down to idle, like I will release the throttle and it will keep on going. I am at a complete loss as I have no clue how to work on bikes. Heck I don't even know what half the parts are used for or called when I see them in other posts. Basically can someone explain this so an idiot like me can understand? Also I see that there is a place labeled kick starter but no kick starter. That would sure be nice to have. It there any way that one can be added? Really any help or advice would be greatly appreciated. Thanks a ton.
So I have this somewhat beat up 1987 DR200 and ever since my friend bought it and I bought it from him, it doesn't seem to have a functional rev limiter or at least one I can distinctly hear or feel, so I decided to try it out a few days ago and just open it up with the clutch pulled - nothing too crazy or anything I haven't done before, but pretty high. I bailed pretty soon because I didn't hear the telltale cutoff of the limiters on my other bikes and didn't want to damage it, but when I backed off and it fell, the bike was VERY loud from the top end. A sort of rattling/ticking noise. I accelerated again before I realized I should stop and noticed the power was about half of what it was, so I killed it and pushed it home. I looked and the intake valve nut was completely loose and the valve had literally 1/4" clearance :/ Tightened that up to spec and ran again - was a little quieter, but still very loud. Removed the valve covers and head to check the piston and valves; the piston seemed fine, although I'm not sure exactly what to look for, but basically I thought a valve may have floated? but didn't see any signs of damage. This was my first time tearing down a top end with some idea of what I was doing. The valves looked like they sat fine in the head with no obvious damage. I put the bike back together and waited overnight for the gasket maker to cure, adjusted both valve clearances to spec today, and started it up. Fires up fine so I managed to set the timing correctly, but still very loud and rides with about half power. Feels like the beater CB125Ts I took my safety course on lol. The sound is slightly different than it was before the valve was tightened, more of a slappy tick with less rattle. My conclusion is maybe rings, explaining the poor power and maybe the sound. 90% sure the sound is coming from the top end as well. Does this sound like a likely explanation? Rings for this bike are cheap, but I've never bought them before and my usual part site offers standard, oversize 0.5, and oversize 1.0mm ring sets - which should I buy and how do I know? Lastly, from what I've listed, is it safe to ride the bike if I can live with the poor power until I can find a solution...?
Hello Chaps Nick from England here. First post so go easy on me :-) i wonder if if anyone can offer views on feasibility of increasing the capacity of a Chinese Suzuki GN125 derived engine beyond the "big bore" limit of 147cc. Following the advice found on this forum I've fitted a Chinese 147cc big bore kit, a VM26 carb and a DR200 cam...actually a Chinese QM200 cam, but I'm told they are the same thing. This is nice, but I would like to increase the capacity further, ideally up to 200cc. I know the stroke is longer and bore is wider on a 200cc variant so im guessing I would need a DR200 crankshaft, con rod, piston, barrel and head. But, in big handfuls, is this likely to be compatible with the 125 crank case and transmission ? ive posted here because there are (or were a decade ago) some guys who seemed to know everything about swapping bits between the small two valve Suzuki engines. Whereas other forums tell me I can get major performance increases by changing the air filter and spark plug :-) Thanks in advance Nick
