Dual Sport, Offroad Bikes

Hello guys. I didn't see an introduction spot in the forum, but I need help asap. I'm in PA and I fear one of my last riding days will be tomorrow. Let me start with an intro. I'm a 26 yr old male. I am an Isuzu nut. I frequent in a few isuzu forums. I own a 1989 I-Mark and a 93 Isuzu pup and have owned MANY Isuzu vehicles. I own my 1980 175 DT along with a 1982 Honda 3 wheeler 125 bored 50 over. I'm still getting the 3 wheeler put back together. I love off roading and ATV riding. I got my 175 DT recently for $300 and it's in pretty good shape. It's missing somer lights and stuff and I'm putting some on it so I can street ride it also. Now with that aside here is my probl…

hi there im new to the forum and can i just say it looks very helpful indeed.I have a dt125r 1990 on a g plate and just had a rebore and new piston i have a small question it has a powervalve but not one thats operated by a servo(if you know what i mean)How do i make sure this is in the correct position as mine seems to spin free and doesnt look like anyway of locking it off,I really dont know how its supposed to work any help would be great and not start the bike since replcaing the piston as i dont know what damage can be done by the pv being in the wrong postion?

This is my first forum posting. Just bought a 1973 DT3. The gas cap gasket is really bad. They don't seen to be available from Yamaha. Anyone have a source for these or is there another fix?

Hi, have just got my DT175MX running again, see previous threads, and I keep feeling for a bigger gear when riding in top. As far as I know I am on standard chain sprockets for a 125. Is the 175 different and if not which way do I go, bigger front sprocket or smaller rear. Anyone know, done it before? Thanks Phil

ok so i dont have a big attention span and on my TW125 it was right there... but i cant figure out how to take the seat off ... as i said with my tw it was 2 bolts on the underside of the seat (quite annoying) why why why do 125's need to have bolt on seats and be so annoying to remove, ok with a 125 your only under the seat to fix stuff but cmon wut happens if your out on the road and tools are limited lol an e-mail would be nice cmon the yamahas Edit: Please dont post your contact details in the forum Thanks...

Hi there all - I'm new here and I had a question for you experts. There is a 1982 Yamaha DT100 Enduro for sale not far from me and I was wondering what you all thought about this model. I must admit I am a complete noob when it comes to these bikes, but I am looking for something that is cheap, dependable, easy to maintain, really fuel efficient, and can carry me and the wife around on the family farm. The info I got from the seller says: What do y'all think? Should I drive out and take a look at this thing or pass? What would be a reasonable offer for a bike like this?

Hi If you have a road registered WR400F from circa 1999, I'm wondering if you could take a look at your V5 and help me fill out the following boxes on my application form for a first registration (I have some of the values already from the web, but I'll reproduce here if you can check it?): Variant: Version: Length: 2275mm HC g/km or g/kWh: Unladen weight: 113kg Number of Seats: 1 Max Net Power: 35.3kWh Width: 835mm NOx g/km or g/kWh: Power/Weight ratio: 0.312kW/kg CO2 g/km: Particulates (pm) g/km or g/kwh: CO g/km or g/kWh: HC + NOx g/km: Stationary Sound Level dB(A): Engine Speed Sound Level: Drive-by Sound Level dB(A): Thanks in advance for …

Which is best: Malossi og Giannelli. What will be the outcome of fitting a 50 cc silencer to a 125 cc m/cycle

I fancy an MT-03 for an every day all year round commute bike? are they any good I have had a ktm + ccm in the past so know what to expect from a big single.

This bike starts out great and runs awesome! alot of fun to ride. But after about ten minutes or so the bike starts bogging out and then lurching and then stalls out completely. You have to wait for the engine to cool down to start it again (about 20-30 minutes) and run it. But the weird thing is is that after it stalls it will idle roughly on choke and then it will start idling really fast and then stall out. It is the weirdest thing. I am running 32:1 motorcycle two stroke with premium gasoline. I've cleaned the carb too and the plug is wet after trying to start it. I also took the plug out after it stalls and it has good spark out of the cylinder. Any ideas? I…

I have 2 1974 DT 360's. The clutch won't engage on one of them I am restoring. The lever on the engine bottom moves freely - almost too easily, like it is not engaging the push rod. I have the clutch cover off and see no movement when the lever is pulled forward. Any ideas?

Managed to find myself a nice 1978 DT 175 MX the other day, after a bit of bartering I got the bloke down to £120, she's a bit rough, but after swapping the crank (looked like it had been sat in water for 10 years), she ran like an absolute dream. Anyway, I'm just wondering what they fetch running & on the road nowadays, and if anyone knows any places to buy new old stock. I'm also thinking about parts, I seem to remember pretty much _everything_ on the DT 125 and 175's were the same, apart from the bores and the fact the 175 head had 6 nuts instead of 5 or somthing, and the 5 plate clutches on the 125 instead of the 6plate clutches of the 175. I'm wanting to…

Hi, help wanted. Have been a bit unlucky or un-careful recently as I have managed to hole two pistons on my bike. I had just finished rebuilding the DT as a 175 (previously 125 which holed a piston sparking off the 175 conversion) and it had been running fine except that when I checked the spark plug it was a bit sooty (dark brown) so I went one grove down on the needle, from 4 from the top down to 3. Took it down the bypass to see what it would do and holed the piston again this afternoon!! Oh BUGGER !!! The advice wanted is, do I need to strip the whole thing down again? Is it possible/safe to remove the barrel etc and turn the engine upside down and spray engine cleane…

I have a tdr250 and about every 100 miles the porceline in the spark plug electrode appears to stop working and has a hairline crack, they are ngk br8es, has this happened to anyone else?

Hey everybody, i am new to this board and joined because i need alittle help from the dirt bike gurus. i am a chopper enthusiast and am trying to help a neighborhood kid who came to me looking for help. he saw that i work on bikes in my garage and stopped to ask if i could fix a dirtbike he found. i believe the bike is a late 60's to early 70's yamaha dt250? he found the bike abandoned in a field close to his home. it had been sitting there for years but the frame and engine where still there, everything else people took off. there were still some wires connected from the engine to the coil. my question is if anybody could help me figure out how to connect the wiring so i…
