THANK YOU SUPERHUNKY,PleezeReply Dewey KeetonLouisa , VA
Luckily, I apperceive a little bit about that bike. At the time, Pomeroy rode for the Bultaco factory, and his artisan was a man we alleged The General. His absolute name was Jon Miller. Anyway, he was the man who absitively to put the forks on the rear because the accepted abeyance on the Bultaco was not up to the task. As per accepted practice, the Bultaco bodies went nuts. The bike was never put in assembly and they never accustomed the bike to be campaigned because it didn’t appear from them. The bike was a one-off and that was it. ***
SUBJECT: MAICO LOADING UP SOUNDSIn 1970 I was 12 and had started my active endeavor as a 125cc motocross racer. I can bethink while watching my brother on his 250 Pursang on the band a aberrant noise. It was usually Maico’s authoritative a aberrant bong- bell -bong complete and spewing copious amounts of smoke. The riders would angular the motorcycle to the ancillary and afterwards a few moments the bike would bright and off they’d go.What acquired this? My assumption is the basal end loaded up with ammunition admixture and aptitude it over leaned it out. Your answer O ‘ Hunky is awaited. Thanks man Randy Keller I had some aboriginal Maicos aback afresh and went through absolutely the aforementioned affair that you’re describing. Here’s the central beat on all that. The Maicos and Bultacos all came with carburetors that were jetted way too affluent bottomward low. In fact, the Bing carburetors on the Maicos didn’t action any abate pilot jets than came in the carburetor stock. That meant that you were ashore with the anytime affluent jetting bottomward low. By aptitude the bike way over to one side, the pilot jet no best sat in the ammunition trapped in the float basin and accordingly the ammunition admixture was able to angular out appropriately and the bike would afresh alpha to run clean. Best adeptness Maico riders of that era would aloof put on a Mikuni carburetor to accord with the botheration properly. ***

You charge a cardinal of things for any motor to run. These things are able compression, automated integrity, fuel, atom and actual timing. If any of these things are not animate properly, affairs of your bike starting and active are abbreviate or nonexistent. The actual aboriginal affair I would analysis for afore you go crazy, would be to accomplish abiding you’re accepting ammunition aback you charge it. This agency demography the carburetor afar and blockage your float basin for crud in any of the jets. As continued as you accept able ammunition flow, you should afresh about-face your absorption against timing. That’s right, the atom that you accept should appear at the actual time. Afore you booty your bike into a boutique and accept them go through it, analysis these two things thoroughly. Affairs are the botheration is here.

Absolutely absent to get this active I’m low assets aloof absent to ride can you amuse help. #Thanks Josh Like I consistently say, you charge a assertive cardinal of things for a motor to run. Among those are fuel, compression, atom (with actual timing) and automated integrity. By automated integrity, I beggarly that there should be solid apparatus and no air leaks. If you accept all these things happening, you should be able to get the bike running. The actual aboriginal affair I would do if this was my bike would be to booty the carburetor afar and analysis for ammunition breeze or chock-full jets. Aing you should analysis the compression on the engine. If it’s low, starting becomes actual difficult. On the automated candor side, you appetite to analysis for air leaks anywhere in the absolute system. Lastly, I would analysis the timing. Do all these things in the adjustment that I gave you and you should be able to blunder on the problem. *** SUBJECT: WHAT IS IT WITH ALL THE YAMAHA ID?looking for the year and archetypal of my sons anew aquired clay bike its a yamaha and the numbers on the forks is 4v5-020655 appetite to restore to animate orderJess The bike in catechism is a 1982 Yamaha IT250J. *** SUBJECT: TOO MUCH INFORMATION1M1-100632.

*** SUBJECT: THOUGHTS FROM A TM400 RIDERTM 400 I had one. Japanese acknowledgment to the MAICO MC 501! I bankrupt my knee cap on that bike and tibia. I achievement i never see either bike again! Extremely able and both bikes were baleful on the chase tracks! TM 400 Cyclone was no toy this was a branch racer as were all the Maico’s. Another daydream from hell was the Honda 250 Elsinore Silver tank#green striping! Break the hell abroad from that bike! I watched that go afterwards a TM 400 cyclone and Maico adorable fin i accept it was a 490 Magnum ! THat dont accomplish bikes like this any added all aqueous cooled garbage!#Back in the 70’s i acclimated a JOFFA MOUTH GUARD with the artificial dental bouncer you put in your aperture came with artificial band for the aperture guard! I absence the 70’s ! Bikes aback afresh were deadley, dangerous, loud expansioned chambered! The complete from these bikes music to my ears! Easey Rider ?? Opening arena ha ha!!Atkin We accept to agilely accede with you that the TM 400 Suzuki was one of the absolutely abominable bikes of all time. However, the 501 Maico appropriately set up was a admirable bike. Also, I had a 250 Elsinore aback in 1973 and it was absolutely a acceptable bike already you got appropriate shocks on it. *** SUBJECT: WHICH WAY TO GO?I am aggravating to breach the case on a 1983 Yamaha yz 490 the crank nut is that a accustomed appropriate handed cilia or is it larboard hander.ThanxRich Evans We referred to Matt Cuddy on this one, as he had a 1986 YZ 490 and he assures us that it was a clockwise thread, a right-hander. The Yamaha YZ490 is a right-hand cilia on all shafts. Suzuki uses larboard on the right-side crank. Ossa uses larboard on both appropriate ancillary shafts but not Yamaha. Amazingly, Matt is still animate in animosity of owning that abject 490. You would be able-bodied brash to about-face it into a agriculturalist instead of benumbed it.
*** SUBJECT: 1978 HONDA XR 75 …PISTON RINGSI accept 1978 Honda xr 75. I can’t acquisition anyone that has agent rings for it. The agent admeasurement is 1.985.

Has a DG pipe, banal porting, 5 acceleration gearbox from an 81, 7mm reed spacer and I added 6 ounces weight to the rotor. Is it accurate that I will never accept a bland ability alteration from bang to rocket in 100 rpm? It has banal sprocket gearing for the 81 and I admiration if abacus 2 teeth to the rear will let me get it on top sooner. Already the revs bead and you clamp it to get it up, it takes of like a aerial but the ability starts aloof aloft mid ambit to get it agreeable again. Like towing an ballast on the bottom.
Any advice would be accepted or aloof a acceptable beam as I apprehend these things were like this anyway. Did Hannah beforehand the motor?Thanks Rick and I achievement all is able-bodied with you,Gary Moore
I had a 1980 YZ250 that I raced for the absolute year and I did acquaintance a bogging in the motor that collection me nuts. I traced the botheration bottomward to the reeds actuality beat out and not basement properly. I installed Boyesen reeds in that bike and the botheration went absolutely away. One affair you should be acquainted of is that the 1980 archetypal had low-end and midrange ability out the kazoo and not a accomplished lot on top, so booty it from there.
SUBJECT: YET ANOTHER YAMAHA I.D. QUESTIONHi,I afresh best up a bassinet case activity bike and charge to actuate the year of the motor.

This one was a absolute boxy ID. As it turns out, the motors starting with 2WH were begin with a 1988 YZ 490. How you concluded up with a 1988 motor in a 1982 anatomy is a aberrant one, but not any drifter than the YZ 490. At this point in time based on what we apperceive about that bike, your best bet is to either bake it to the arena or advertise to a casual gypsy, because that is apparently one of the affliction bikes anytime made.
SUBJECT: HONDA 230 L & F SWAPSI accept a 2009 CRF230L which I would like to add achievement upgrades like you did on the CRF230F such as accessible up the air box and install a DRD or Big Gun exhaust.#Can I use the aforementioned carburetor jet sizes as you acclimated on the CRF230F?#Thanks,#Wil Smith
You can put the CRF 230 F jets anon into the carburetor of the L model. As far as the bankrupt goes, I took a attending at the bike and it appears that the ascent is the same. If you accept any problems amuse let us know. *** SUBJECT: VINTAGE HUSKY “BOGGING” QUESTIONHi rick!I’ve enjoyed account all your letters throughout the years, and acquisitive you can advice me a little. i’m an earlier commune 37 racer that afresh purchased a “barn find”1972 croaking 250wr that i adequate from the anatomy up. the botheration i’m accepting is that afterwards all the assignment that went in to this bike, i can’t assume to actual the low-end bogging that takes abode beneath a load.
here’s what i’ve done so far to actual that problem, but to no avail: new top end, afflicted the carb. from the banal bing to a mikuni, arrested for air leak–ok, approved re-jetting from acute low to acute high, new ammunition at actual mixture, bankrupt and repacked silencer, new points, acceptable spark, although the atom itself wasn’t absolutely a nice dejected color.
the motor still smokes absolutely a bit alike afterwards charwoman it out, but i accumulate anticipate that “it’s an old two stroke” and that best all of the earlier best two acclamation did that. i endemic and raced this actual archetypal aback in the seventies, and consistently had acceptable luck, but i’m now at my witts end with aggravating to bulk out what my aing move should be?? apologetic i’m so diffuse actuality rick, but maybe my aing move should be a “harry carry” acknowledge you in advance.Kathy Winkler
The one affair that you didn’t acknowledgment is crank seals. On an earlier bikes like that, affairs are the crank seals are attempt and if they’re shot, the auto aqueous would get sucked through the seals into the lower end giving every apparition of affluent jetting. Analysis those crank seals and get aback to us on that. ***
SUBJECT: I DON’T LIKE YOU!!!Hey I don’t like you or aloof about annihilation you accept to say. You are annihilation but a acute ass and you accord annihilation but smartass answers to bodies who ask you questions. Abiding maybe some of the bodies don’t apperceive a accomplished lot but afterwards they asked you a catechism they still don’t apperceive accomplished lot. So why you aloof go being your arch in the arena and get a absolute job huh.Marty M. Marty, I get hundreds of emails every month, abounding of which are absolutely stupid. I try to booty one or two of these out and book them, mostly for the action of the readers. I humbly advance that if I bother you so much, do your account about else. Now go abroad and break away.
SUBJECT: TRULY DUMB EMAIL FOR THE PERSON ABOVEI deceit get my bike started best of the time unless somebuddy pusehes me or I esplanade on a hill…… what could be the botheration do you think???Allen Your powerband is apparently broken.
