    Pulled the intake boot and reed box out today. No porting, but piston and reeds look nice.

    Feel pretty confident that the top end (at least) is good.

    Any suggestions on an aftermarket silencer and jetting? Remember, I've got a Mikuni VM34 no airbox and a Uni filter, high elevation (5200-7200 ft).

    Got it running again and went for a quick test ride a few days ago (sans silencer)...

    Drained old gas, sealed the cracked intake boot with some Plasti-Dip (a chemical resistant liquid rubber product), cleaned the carb, and lowered the jet needle a notch. Had to set the idle real high to keep it running, a bit boggy on the low end, but very strong on top. Acceleration on these things is amazing, even when the tuning is off. Felt like light speed quickness compared to the 200X. Shifting felt good, although I only got up to 3rd gear.

    Head gasket leak appears to have stopped, verdict is still out on the front sprocket seal, but if it is leaking it appears to be minor. Didn't see any oil near the drain plug this time either. Motor seems decent.

    Ordered a DG Type II silencer from ShecklerRacing.com today. Lowest price I could find, low shipping rate (total cost incl shipping was $101), CA location and slick website kinda suckered me in...didn't realize it's owned by that Hollywoodish young skate star Ryan Sheckler and his dad Randy until later...

    I hope they don't lag on shipping it to me because I'm itching to have some fun with it, and all I need now to get me on the trail is the silencer and the front brake MC; cross-referenced the part#'s and discovered that both the '83 200X and '84 250R use the same MC up front so I should be able to use the Nissin that is on my 200X right now.

    Has anybody bought anything from Sheckler Racing? If so, how long did the part take to ship?
    Also decided to sell the 200X, got it advertised locally.

    Thanks for the updates. Keep em coming. Glad the oil leaks seem to be minor.

    Sheckler dropped the ball on my DG: sent me an email 3 days later saying their supplier was currently out of stock and estimated wait time was February...

    Took another 3-4 days to issue me a Paypal refund, I ordered another one off Starcycle.com, Paypal shipped to my old address but luckily I had my old roomates # who still lived there and was able to drive over to Reno and pick it up...Meanwhile I've been fighting a RAGING cold/flu for over a week and been busy working so I haven't had an opportunity to mount it until yesterday. Trike is missing the muffler hangers so I had to create my own...

    So I got my DG mounted last night with a little redneck engineering...and with a little more inspired redneck tinkering managed to get my mismatched throttle cable barrel to thread into the carb cap (this trike is starting to look like a tribute to redneck design)...

    Got it running pretty decent today, and went for a brief test ride. Other then some occasional bogging at random throttle positions, the tuning seemed pretty close to where it needed to be. It idles great and I could find no leaks around the carb intake when I sprayed starter fluid around it (the Plasti-Dip patch job appears to have worked). Rode it to the end of my drive, seemed fairly smooth and awesome power as I ripped it up to 3rd gear (blows me away how quick it feels compared to the X), downshifted to first as I neared Eastlake Bvd and did a donut in the gravel with ridiculous ease and very light throttle, then took it into the hills for further testing.

    It felt pretty strong and smooth for the most part, narrow 250 2 stroke powerband definitely a handful to control compared to my X, but I was taking it easy trying to get a feel for the thing while still getting it revved up enough to get an idea of it's state of tuning (also still don't have a front brake so I was being cautious). A couple times it appeared to be bogging a bit in the midrange (almost sounded like it was low on gas), and I only had about a gallon in the tank, but I hadn't actually gone that far (maybe a mile or so), but I decided to flip the petcock to reserve, and turned around to go back home as soon as I got to the first plateau.

    It seemed to be running fine on the way back down. I was about 1/8th of a mile or less away from home and there's this wicked downhill hairpin turn on loose soil where I've been able to get really sideways fairly easily on my 200X by nailing the throttle and throwing my weight over the fender at just the right moment. So I tried pitching the rear end around a little bit but was late on the throttle, and as my momentum carried me around the turn I tried laying up on the twist throttle, but somehow I ended up pinning it in my effort to hang on (I think THIS is the reason ATC's come factory equipped with thumb throttles), and that mother-effer all of a sudden got on the pipe, I went rocketing up towards the inside edge of the fireroad up a steep berm and I think (things got really fuzzy here because it happened so FAST) I barrel rolled it towards the opposite side (heading towards a steep drop off the hill). At one point I remember being completely upside down in my seat, wheels in the air, then the trike kept rolling and spit me off it, heard the sickening thud of the wheeler as it impacted the ground, hit a rut , and incredibly, uprighted itself wheels down on the edge of the road, ass end a couple feet from dropping into oblivion, front wheel stuck perpendicular in a deep rut...

    Real bad place to have a wipeout...I was very fortunate to have not totaled myself or the trike, and it is somewhat miraculous that I got away with just a couple very minor scrapes and bruises.

    The R didn't fare as well, but so far as I can tell it seems to have escaped serious carnage: badly bent handlebars, broken throttle, some new dents in the tank, and a little gash near the center of the upper tripple tree...the forks and frame steering/headtube looks straight, but for some reason when I look at it from the side the rake seems to have grown... ...hope it's just an illusion

    I know some of you are thinking the cause of the crash is solely due to rider error, and it's true I'm not used to the power of a screaming 250 2-stroke trike, but I am a good experienced rider, and was taking precaution...rider error not withstanding, I don't believe that wreck would have happened with a thumb throttle (could have backed off the gas and hung on to the grip thru that high G turn )...it was a pretty effing freaky feeling trying to let off the throttle with physics making me do the opposite and pinning it WFO... ...I was leery about the twist throttle to begin with, and now I"LL NEVER HAVE A TWIST THROTTLE ON MY TRIKES EVER.

    Video of it running after the crash:
    Some








    Black stuff on silencer is melted fender plastic...surprised no one's noticed so far that these aren't 2nd gen fenders...I'm guessing they came off a 1st gen...more redneck engineering...

    Sucks I crashed it on very nearly my first ride, but on a positive note, motor seems strong, tuning is not far off...and it fired up first kick after the wreck...

    Oh yeah...I had my helmet on...always wear the gear kids
